Re: [Catalyst] error handling (Chain where ajax and non-ajax actionschain off)
Hi,
From: Eden Cardim edencar...@gmail.com
in Controller::Artist:
sub error_404 :Action {
Can I find more information about the :Action dispatch type?
Is it just a replacement for :Private? Or it is something different?

Re: [Catalyst] Accessing DB from external model
From: Mike Raynham catal...@mikeraynham.co.uk
Hi,
I am fairly new to all things Perl and Catalyst, and would like to know if
what I am attempting to do is correct.
I've recently finished reading 'The Definitive Guide to Catalyst', which
has been very helpful, but I am still a little confused about separating
my business logic from my Catalyst application, and accessing the database
connection from my non-Catalyst application.
At the moment, I have my external class in the lib/MyApp directory. It
uses the connection info found in MyApp::Model::DB, like so:
---
# lib/MyApp/MyExternalClass.pm
MyApp::MyExternalClass
use MyApp::Model::DB;
use MyApp::Schema;
my $connect_info = MyApp::Model::DB-config-{connect_info};
my $schema = MyApp::Schema-connect( $connect_info );
# Do stuff with $schema...
---
That works, and I can connect to the database. However, I have searched
this mailing list, and found this:
http://www.mail-archive.com/catalyst@lists.scsys.co.uk/msg00817.html
Here, the connection information is moved from MyApp::Model::DB to
MyApp::DB, and then Catalyst::Model::Adaptor is used to glue
MyApp::Model::DB to MyApp::DB. Is it a good idea? MyApp::Model::DB
appears to be part of the Catalyst application, so if I want to access the
database from an external model, it makes sense to me to move the
connection code outside of the Catalyst application.
Regards,
Mike
The best idea would be to put the connection information in the
application's config file like in the example below. (This example uses a
Perl data structure, but you can use any configuration type accepted by
Config::Any).
'Model::DB' = {
schema_class = 'MyApp::Schema',
connect_info = {
dsn = 'dbi:Oracle:host=10.10.10.10;port=1521;sid=ora8',
user = 'user',
password = password,
#name_sep = '.',
LongReadLen = 100*1024*1024,
LongTruncOk = 1,
on_connect_call = 'datetime_setup',
on_connect_do = [
alter session set NLS_COMP='LINGUISTIC',
alter session set NLS_SORT='BINARY_AI',
],
},
},
The model will access the connection information directly if it is defined
in the config file, and you can use the data from this config file in any
other external program.
You can use the module Config::JFDI for using the Catalyst config file
easier.

Re: [Catalyst] Accessing DB from external model
From: Darren Duncan dar...@darrenduncan.net
For any configuration details that might vary either per application or per
deployment, make these user-configurable parameters of MyDBLib, with then
each
of your applications would supply arguments to it when instantiating a
MyDBLib
object; in the Catalyst app's case, said arguments would be in your Catalyst
app
config file as is normal for MyApp::Model::DB.
For any configuration details that are unlikely to vary per application or
per
deployment, especially if they are details for which your actual code would
vary, then put these directly in your MyDBLib code instead.
Yes you are right.

Now some of this looks wrong to me; a lot of those details should be in your
MyDBLib code instead of the config file. Your config file should instead
look
more like this:
'Model::DB' = {
schema_class = 'MyApp::Schema',
connect_info = {
host = '10.10.10.10',
port = 1521,
user = 'user',
password = password,
},
},
These are more details that a non-programmer user would set.
I agree and yes, that sample code could give bad ideas.
In my case I am the app designer, coder, maintainer, site admin, everything but
the web designer and I've done it so for not specifying these settings in more
places.
Is there another place where I could put these settings for a certain DBIC
schema?
For example, can I put them in the MyApp/Schema.pm, orsomewhere else? Can you
give an example?
Thanks.

Re: [Catalyst] myapp_test.pl - running code from the command line
From: Jonathon Soong j...@investmentscience.com.au Yes I realise now it might make more sense in the Model, but at the moment it is in the Controller (it is someone else's code, so more difficult for me to refactor). There are two questions I have then: 1. How do you call a Model's function from the command line? 2. Is there no way to call controller methods that require authentication? Thanks Jon The model can be just a thin wrapper for your non-catalyst modules like MyApp::Model::DB could be for your DBIC schema. And you can use your non-catalyst module from a non-catalyst script that can be ran by a cron job. If the code is in the controller and you can access it by web only, you can create a script that accesses your running Catalyst application, does the login (submits the login form with the necessary username and password), saves the cookie and resends that cookie for all the requests you need to do after logging in.

Re: [Catalyst] Has anyone read the book Catalyst 5.8 : The Perl MVCFramework yet?
IMHO the dispatching is a very important chapter for a web framework, especially for Catalyst that has so many things to offer in this field. And another important thing is to show how Catalyst works alone, without an ORM, without a templating system, without a form processor, with the warning that this not the right way to do it, but it is very important for the beginners to see which are the things that depend on Catalyst and which are those that depend on the ORM or templating system. And another important thing is to use a lot of warnings that This is not the right way when DBIC code is used in the controllers for beeing easier to understand by the beginners, but to let them know that that way of doing things should be avoided. And it should be very helpful to show examples of models that get data and save data, but models that don't use an ORM like DBIC. --Octavian - Original Message - From: Kieren Diment dim...@gmail.com To: The elegant MVC web framework catalyst@lists.scsys.co.uk Sent: Tuesday, October 26, 2010 7:57 AM Subject: Re: [Catalyst] Has anyone read the book Catalyst 5.8 : The Perl MVCFramework yet?

Re: [Catalyst] Returning to referer - which action to take?
From: Ekki Plicht (DF4OR) e...@plicht.de Hi. In my app I use I18N, so the visitor should be able to select his or her language at will. The available languages are available on all pages for selection. Once selected the preferred language is stored in a session cookie, otherwise the automatic mechanism of I18N uses the preferred language set in the request header (if any) Can't you use I18N's mechanism for detecting the current's page language? For example, you can have urls like: www.site.com/en/dir1/dir2 www.site.com/ro/dir1/dir2 In this case you may store the chosen language in the cookie only for displaying the first page of that site in that language the next time the visitor accesses your site. Of course, you don't need to create a En or Ro controller for doing this. You can override prepare_path() or you can use the module: http://search.cpan.org/~mendel/Catalyst-Plugin-I18N-PathPrefix-0.02/lib/Catalyst/Plugin/I18N/PathPrefix.pm There is another example that uses the chained dispatching mechanism you can find at: http://www.catalystframework.org/calendar/2006/18 Imagine that currently page http://localhost:3000/foo/1/bar/2 is displayed in english. Now visitor clicks on http://localhost:3000/sellang/de , the internal variable for language is set. This normally involves per-user session management and cookies. Now I want to display the very same page (/foo/1/bar/2) but in german. It is not a good idea to use the same URL for pages in different languages, because they won't be probably all indexed by the search engines. You can add a query_string like lang=en but it is not nice and it requires too many changes if your app is already half-built. Serving the pages in different languages works fine with C::P::I18N, but I can't figure out how to return the visitor to the refering page. Simply redirecting to the referer does not work, because a prepared cookie isn't preserved over a redirect (isn't it?). A redirect is nothing else than a HTTP header that tells the browser to what URL it should visit immediately. So the cookie already set by the first request should be sent by the next request too. Ideally, the link to each language-changer on each page should display the same page in the chosen language, and not the first page of the site or another default page. So if the visitor is on the page: www.site.com/ro/dir1/dir2 and clicks on the English link, it should see immediately the page: www.site.com/en/dir1/dir2 The referrer page is the one in Romanian so if the user clicks on the back button, the /ro/dir1/dir2 page will be re-displayed.

Re: [Catalyst] best practices for handling forms?
Hi,
A clean example that uses HTML::FormFu is:
package MyApp::Controller::Foo;
use Moose;
extends 'Catalyst::Controller::HTML::FormFu';
# or just use parent 'Catalyst::Controller::HTML::FormFu' if you don't use
Moose
sub edit : Local FormConfig {
my ($self, $c, $id) = @_;
my $form = $c-stash-{form};
my $foo = $c-model(DB::Foo)-find($id);
if ($form-submitted_and_valid) {
$form-model-update($foo);
$c-flash(notice = Foo was updated successfully.);
$c-res-redirect($c-uri_for_action('/foo/index'));
}
else {
$form-model-default_values($foo);
}
}
sub edit : Local FormConfig {
You can use Path or the chaining dispatch type or something else, not only
Local.
If you use the attribute FormConfig, it will search for the form placed by
default in
root/forms/foo/edit.conf
If you want to use another specified form, you can use something like:
sub edit : Local FormConfig('path/to/another/form') {
my $form = $c-stash-{form};
If you use the FormConfig attribute, it will place the form in the stash
automaticly so you just need to get it from there.
my $foo = $c-model(DB::Foo)-find($id);
This uses DBIx::Class result class DB::Foo for getting the $foo record.
if ($form-submitted_and_valid) {
This will be true only if the form past all the validation and constraints.
$form-model-update($foo);
This will update the $foo record in the database. In order to work this way,
you need to have defined the database schema in myapp.conf like:
'Controller::HTML::FormFu' = {
model_stash = {
schema = 'DB',
},
},
And in the edit.conf form configuration file (defined below using
Config::General) you will need to have defined the resultset like:
model_config
resultset Foo
/model_config
$c-res-redirect($c-uri_for_action('/foo/index'));
$c-uri_for_action is prefered because /foo/index is not a URI but an
internal path to the index action from the Foo controller and this code
doesn't need to be changed even if the public URI to that action changes.
$form-model-default_values($foo);
This fills the form with the values from $foo record when the form is
displayed.
HTH.

Subject: [Catalyst] best practices for handling forms?
Hi,
I am curious what everyone thinks as being the best practices for
handling forms in Catalyst. Are there any Catalyst applications you
have run across which are good examples of how to use Catalyst's
features to handle forms?
To illustrate what I am getting at, below is typical Rails (v2)
controller code which implements updating the attributes of an object:
def edit
@book = Book.find(params[:id])
@subjects = Subject.find(:all)
end
def update
@book = Book.find(params[:id])
if @book.update_attributes(params[:book])
flash[:notice] = 'Book successfully updated.'
redirect_to :action = 'show', :id = @book
else
@subjects = Subject.find(:all)
render :action = 'edit'
end
end
In Catalyst, this would be appear something like (and please correct
me if I have made any errors here):
sub edit :Args(1) {
my ($self, $c, $id) = @_;
... set up $c-stash for template 'edit' ...
# no need to set $c-stash-{template} - will be set from the current
action
}
sub update :Args(1) {
my ($self, $c, $id) = @_;
...process form...
if (form is valid) {
...perform updates...
$c-flash-{notice} = 'Book successfully updated.';
$c-res-redirect('show', $id);
} else {
... set up $c-stash for 'edit' template ...
$c-stash-{template} = 'edit';
}
}
Any comments on this architecture? Is there a better way? My main problems
are:
1. The code ... set up $c-stash for 'edit' template ... is duplicated
in both edit and update (which is also true for the Rails code).
2. Having the template name defaulted from the current action is nice,
but that means we have to explicitly set it in the update method. Is
it better to always explicitly set the template name in a controller
method? Then update could perform a $c-detach('edit', $id) or would
you use $c-go('edit', $id)?
Thanks,
ER

Re: [Catalyst] Defining ARRAY in Config::General config
Hi Andrew,
I tried:
C:\Documents and Settings\Teddy perl -MConfig::General -e print
$Config::General::VERSION
2.49
#The program:
use Config::General;
use Data::Dumper;
my $conf = Config::General-new('config.conf');
my %conf = $conf-getall;
print Dumper \%conf;

foo [ bar ]
/array2
foo [ bar ]
#The result:
$VAR1 = {
'foo' = '[ bar ]',
'array2' = {
'foo' = '[ bar ]'
}
};
So it seems it doesn't work as it should because it creates a scalar that
contains [ bar ].
Am I missing something?

Re: [Catalyst] best practices for handling forms?
You don't need to do the redirect if you don't want it, but it is the
recommended way.
Instead of the redirect, you can forward to another method that prints the page
you want:
$c-forward('foo/success_method', ['possible', 'parameters']);
In that case after the data is stored in DB, the specified method is called.
But after doing a POST request it is a good idea to do a redirect because if
the user would refresh the page, he might send the posted data again.

Hernan, Octavian - thanks for your replies.
Both of you have given examples where the display of the form and the
processing of the form are handled by the same method. In that case in
order to go from one page to the next you always need to use a
redirect. Doing this is very clean, but it involve another
communications round trip.
If the form display and form processing are handled by separate
methods, you can avoid the redirect if you're careful.
Any thoughts on this issue?

No, it wouldn't. The adaptor you showed has a lifetime of the
application, and so it won't be recreated each request.
Thank you all for remembering me this! I used Catalyst::Model::Factory
somewhere else exactly because it doesn't create just a single object
instance like C::M::Adaptor, but I have forgotten.
Also, even if you were creating an object every request (which you
aren't), if you're worrying about this without numbers, then this is
premature opimisation.
Well, it is not exactly without numbers. I have tried
ab -n 200 -c 5 http://localhost/
The result was... 3 to 4 requests per second.
I commented the line that stores the menu in the stash (for not using the
menu at all) and the same command line gave a result of around 33 requests
per second, which is a very big difference.
So I think the buggy part is the module that creates the menu object from
the data structure loaded in the configuration file.
I will first try to use the data structure directly in the TT template
without creating an object from it.
If it would be too slow, I will try to draw the menu entirely in the
template without using an external data structure, although I don't like
this.
Thank you all very much for your help.

then it is used on each request to re-create the menu object.

I don't believe that. But never mind..
I have checked the memory by using the top command before and after loading
the development server and I did it for more times. I've seen that big
difference so I assume that it is the memory used by my app.
I have moved some modules outside lib because they are used only by some
scripts which are ran in a cron job, and the memory usage decreased, but it
is still very high.
Even an empty Cat app started with the development server occupies 36 MB of
RAM.
It is strange that it occupies so much, because I heard that a Cat app can
be used even on an VPS with 256 MB RAM. I use Perl 5.10.0 under Ubuntu
10.04, with the latest Catalyst, latest HTML::FormFu, latest
Template-Toolkit, latest DBIC and I use Oracle.

Whatever component in your application is using InstancePerContext is
leaking.
Are you using it directly yourself, and if not, what components from CPAN
are you using, at what versions?
(Or, look into a debug dump screen, find the things in the stash which
are in an __InstancePerContext key - these are the candidates to blame)
Thank you for telling where to find that information. I don't use
InstancePerContext directly, but C::C::HTML::FormFu uses it.
I have tested an empty Cat app (created with catalyst.pl MyApp) and it was
not leaking.
I have just changed the controller Root.pm and made it subclass
C::C::HTML::FormFu instead of C::C and CatalystX::LeakChecker started to
report leaks and those stash elements were closed to C::C::HTML::FormFu.
So C::C::HTML::FormFu or HTML::FormFu or another module it uses might be the
leak cause.
I reported this to the HTML::FormFu mailing list.
Thanks.

also changed to 1 all the settings for Prefork MPM, but when using the ab
utility, the memory usage increases and it creates swap.
The memory it occupies also increases if I use the internal development server.
So I am pretty sure my app has some memory leaks and I tried to use
CatalystX::LeakChecker for finding them.
It gave the following results, but I don't know how to interpret them and find
the piece of code that create leaks:
[debug] Circular reference detected:
..

| $ctx-{stash}-{__InstancePerContext_158258668}-{c} |
| $ctx-{stash}-{__InstancePerContext_158322332}-{c} |
''
I've also tried to use C::P::LeakTracker by adding it to the list of plugins
and creating the Leaks.pm controller:
package BRK::Controller::Leaks;
use Moose;
use namespace::autoclean;
use parent qw(Catalyst::Controller::LeakTracker);
sub index :Path :Args(0) {
my ( $self, $c ) = @_;
$c-forward(list_requests); # redirect to request listing view
}
__PACKAGE__-meta-make_immutable;
1;
But when I access it, it gives the error below.
Please give me some hints for using these 2 modules, or recommend another way
of finding the code that create memory leaks.
Thank you.
I am using Perl 5.10.1 and Catalyst 5.80025.
Here is the error generated when I access /leaks:

[Catalyst] Create a PHP::Session
Hi, I need to make a program that shares the sessions with another program which is made in PHP and I thought the easiest way would be to generate the session data on the server using PHP::Session. The PHP session file names are of the form sess_po0nkrgqkjcbx7jb2z1ug17vwn. I was able to create a CGI script that can share the session files with a PHP program, but I find it difficult to do it in a Catalyst app. Please give me some hints about the modules/methods that should be subclassed. I first thought that creating a Store plugin would be enough, but then I realised that I also need to generate the file names that have a special name. I tried to do it by using String::Random and overriding generate_session_id and validate_session_id from Catalyst::Plugin::Session but then I've seen that the app create a session file for each new request. I tried to find out how C::P::S::Store::File works, but I couldn't find how Catalyst creates and then finds the file names of the session files. I was sure that the value of the cookie, that SHA-1 signature is also the session ID and the name of the file, but I found that it is not true. The session ID is stored in the session file but I don't know how to reach from the cookie value to the session ID (because I am sure Catalyst doesn't reads all the session files until it founds the good one). Can you please tell me (or tell me where to look for) how the Cat app finds the file that holds the session data? Thanks.

Re: [Catalyst] HOWTO: order_by a field in a related record, for paging
From: w...@serensoft.com
$c-model()-search( {}, {order_by=???, page=$page} )
How do we order_by a field from a related record when pulling a resultset?
We want to order users by team (then by lastname, firstname) and be able to
PAGE back and forth...
e.g. a User belongs_to a Team.
my $team_name = $c-user-team-name;
my $users = $c-model('My::User')
-search_rs( {}, {
order_by = {
-asc = ???user-team-name???, ## howto?
-asc = 'lastname',
-asc = 'firstname',
},
page = $page,
} );
We're wanting to order by team-name, then user-lastname, then
user-firstname.
Here's a perl sort AFTER we have the results:
my $user_collection = [
sort {
$a-team-name cmp $b-team-name ||
$a-lastname cmp $b-lastname ||
$a-firstname cmp $b-firstname
}
$users-all
];
But this approach doesn't allow for paging backward and forward over the
list...?

will trillich
Hi,
You can use an order_by block like:
order_by = [
{-asc = 'team.name'},
{-asc = 'me.lastname'},
{-asc = 'me.firstname'},
],
Or, if there is -asc for everyone, you can use:
order_by = ['team.name', 'me.firstname', 'me.lastname'],
In the order_by blocks you need to use the names of the columns as they are
used in the generated SQL query. For finding those names, use
$ENV{DBIC_TRACE}++.
HTH.

Re: [Catalyst] Alternatives to Catalyst ?
From: Ævar Arnfjörð Bjarmason ava...@gmail.com
...
Now that it's quietened down, I can ask a question. Does this I mean
it's preferable to use
$c-req-{parameters}-{foo}
rather than
$c-req-param('foo')
Obviously I'd rather use the faster method but if I'm breaking the
encapsulation in some ways that's going to bite me later, I'd steer
clear.
Obviously.
Unless you're doing method calls in a tight loop somewhere in your
code you *shouldn't care about this*. Now I've written code that
actually *did* suffer from method call overhead but since you're just
casually asking it's very unlikely that you're doing the same.
Don't sprinkle premature optimizations around your codebase just
because someone produced a benchmark showing one is faster than the
other. You should be doing *profiling* of your entire program, not
micro-optimizing something that's likely 0.0001% of its total runtime.
If I remember well $c-req-param() is not recommended, but not for
performance reasons.
It resembles the method with the same name from CGI.pm, and it can return
not only a scalar value, but it could also return an array if it is called
in list context. So it might break the code if multiple values were sent for
the same variable.

Re: [Catalyst] Alternatives to DBIx?
From: Kiffin Gish kiffin.g...@planet.nl I'd say that rather than spending time studying SQL::DB, which I found complicated and hard to tackle, you might as well invest the same time and energy anyway in figuring out DBIx::Class.

Re: [Catalyst] Alternatives to DBIx?
Hi, From: John Karr brain...@brainbuz.org Working in raw DBI is the opposite of the DRY principle which underlies having a framework in the first place, so I am seeking an alternative. Just as Catalyst uses MVC, DBIx chooses ORM, but that paradigm is not the only way to be effective PERL==SQL glue. From the Manpage Fey::SQL looks like what I want: neatly wrapped and sweetened SQL, without the repetition and overhead inherent in working from DBI. I'm going to spend some time working with it and also with SQL::DB, when I have a more educated opinion I will share it. Both Fey and SQLDB are a nativist approach to SQL (much like TT is to html), and I would argue that in keeping the PERL paradigm of many ways to accomplish a task, the choice between a SQL-native DBI wrapper and an ORM wrapper should be up to the individual, the issue seems to be finding a worthy SQL-native wrapper. If the overhead/speed is the most important thing, then DBI is better than DBIC (by the way is DBIx::Class or DBIC, not just DBIx). But in that case you probably shouldn't be interested in using Template-Toolkit nor Catalyst, because they also have their overhead, and the other higher level modules used for accessing the database have their overhead also and the best solution would be DBI. In my own analysis the Time and Effort to learn DBIx is greater than the Time wasted writing repetitious DBI code, the time I've already invested on DBIx has shown that there is a better way than DBI, but for me it isn't DBIx. Of course that an application that uses just mod_perl handlers and not very many objects, templates, form processors, ORMs... is faster than one that use them, and for someone who doesn't know the interface of those modules is also faster to develop because no aditional learning time is required, but that application will be much much harder to maintain on the long term. If the long term development process is important, then with very few exceptions, the applications should not be optimized prematurely because there may be found other more elegant optimizations than manipulating SQL code directly. Learning the interface of DBIC takes some time, but you shouldn't learn it again and again for each new project, so on the long term the development process will be much faster. If what you don't like at all is the DBIC syntax, then yes, in that case you have a good reason for using something else, but a good idea would be to learn it a little and try to use it in order to see its benefits.

Re: [Catalyst] Catalyst Redirect to https
From: Bill Moseley
2010/3/25 Octavian Rasnita orasn...@gmail.com
The back end servers don't know if the current request is an http or an
https one and on each redirect, they do the redirection using the http
scheme.
(I have also set the configuration option using_frontend_proxy to true.)
Also, because the back end servers receive only http requests,
$c-req-secure is always equal to 0.
I have read that I can set the HTTPS environment variable to On and I
put the following line in the
configuration file of the load balancer Apache server in the
virtualhost that handles SSL requests:
SetEnv HTTPS On
Does that header get to Catalyst? Obviously, check that first.
I have this in a after 'prepare_headers':
$res-secure( 1 ) if lc( $req-header( 'Https' ) || '' ) eq 'on';
The load balancer sends all traffic to the same port. The load balancer
sets that header for SSL traffic.
I didn't know that HTTPS should be an HTTP header and not an environment
variable so I have also added as a header.
I have put in the configuration file of the back end servers (to be sure that
it will reach the app):
SetEnv HTTPS On
and in the configuration file of the load balancer server:
RequestHeader set HTTPS On
And in a test action I have done:
my $body;
$body .= HTTPS environment variable: $ENV{HTTPS}br /\n;
$body .= HTTPS header: . $c-req-header('HTTPS') . br /\n;
$body .= secure: . $c-req-secure . br /\n;;
$c-req-secure(1); #Force it to be true
$body .= secure: . $c-req-secure . br /\n; # Check if it is set
correctly
$body .= uri_for_action: . $c-uri_for_action('/user/login2') . br /\n;
$c-res-body($body);
And the result is:
HTTPS environment variable: On
HTTPS header: On
secure: 0
secure: 1
uri_for_action: http://site.testsite.com:/en/user/login2
So it seems that both the environment variable HTTPS and the header HTTPS are
seen by Catalyst, but $c-req-secure is still equal to 0.
Do I need to add a certain plugin in order to be able to use $c-req-secure
or what could be the problem that it is not set correctly?
I have read in Catalyst::Request:
the URI scheme (eg., http vs. https) must be determined through heuristics;
depending on your server configuration, it may be incorrect. See $req-secure
for more info.
And more info:
Note that the URI scheme (eg., http vs. https) must be determined through
heuristics, and therefore the reliablity of $req-secure will depend on your
server configuration. If you are serving secure pages on the standard SSL port
(443) and/or setting the HTTPS environment variable, $req-secure should be
valid.
I am accessing the site using SSL by the port so I need the HTTPS
environment variable (or HTTP header) but I don't know why $c-req-secure is
still not set.
And finally, even though I forced $c-req-secure to be true,
$c-uri_for_action still uses the http scheme and not https so in the entire
application the redirects won't be done correctly and this is the big problem.
Thanks.

Hi,
Sorry but I haven't provided the correct information.
The problem is that I use a load balancer (Apache mod_proxy_balancer) and it
gets the https request, however it passes the request to the backend Apache -
mod_perl based servers using http.
How do you do $c-res-redirect in cases like this?
The front end server listens to the ports 80 and 443 and the back end servers
to the ports 81 and 82 (they are on the same machine for the moment).
The back end servers don't know if the current request is an http or an https
one and on each redirect, they do the redirection using the http scheme.
(I have also set the configuration option using_frontend_proxy to true.)
Also, because the back end servers receive only http requests, $c-req-secure
is always equal to 0.
I have read that I can set the HTTPS environment variable to On and I put the
following line in the configuration file of the load balancer Apache server in
the virtualhost that handles SSL requests:
SetEnv HTTPS On
But nothing changes and $c-req-secure is still equal to 0, and the redirects
are still done using the https scheme, so I am doing something wrong for sure.
Do I need to have special virtualhosts on the back end servers that handle the
requests that came using https and set the HTTPS environment variable on those
virtualhosts? Or how can I let the Catalyst app know if the requests to the
load balancer were using https?
Please tell me what should I do or where can I find more information about
using a load balancer with https and Catalyst.
Thanks.

From: Christiaan Kras c.k...@pcc-online.net
You can use Catalyst::Plugin::RequireSSL to force https.
Although I think https should be used by your method if that's what the
user access the app with.

Hi,
In a catalyst action accessed using https I do:
if ($c-authenticate({username = $username, password = $password,
active = 1})) {
$c-res-redirect($c-uri_for_action(/index));
}
It redirects to / URI of the site, but using http, not https as in the
request for the current page.
Isn't $c-uri_for_action() able to see that the current URI uses https
and continue to use it or this revert to http is intentional?
Thanks.

Re: [Catalyst] [DBIx::Class::ResultSet ] not equal in where clause
From: David
Hi,
is not possible to set 'not equal' using ResultSet search method? I can't
make it with 'search_literal' method because I need to use a join clause too.
I would like to do something like:
$c-model('DB::Test')-search({-and = [ 'me.name' = 'name', -not = {
'users.id' = 'id'}]},
{ join = 'users' });
If you want to use -and, you can skip it. If you'll want to use the same
table/column in 2 expressions you can add it back.
Try something like:
$c-model('DB::Test')-search({
'me.name' = 'name',
'users.id' = {'!=' = 'id'},
},{
join = 'users',
});

Re: [Catalyst] Which C::View::PDF should I use?
To: The elegant MVC web framework catalyst@lists.scsys.co.uk Hi Charlie, Thanks for that. I've looked at various html 2 pdf tools (I used html2ps for a project about 10 years ago). But lack of even basic CSS support makes the them useless for creating pretty PDFs. In reality, this project doesn't really need PDF output (HTML would work fine), but $customer says it's a requirement, so I've got to make it work for creating pretty PDFs. I've found that a simple way to put values into a PDF is to use PDF forms - position the form fields in the appropriate location in the template doc, and to generate the output update the form fields and write a 'flattened' version of the doc. This means you can use visual tools to layout the doc, and your code doesn't need to know anything except the field names. Do you know if there is a way of creating PDFs in the same way the HTML templates are created, by just putting a variable name in a certain place and render that pdf file by replacing that variable with its value? (Without needing to specify the position where those variables will be placed) Thanks.

Why do you need this subroutine?
It should be reached only by the authenticated users, and if somebody

you can get this information in the other subroutines also.

From: Kiffin Gish kiffin.g...@planet.nl
Well actually I want to relate it to the timezone of the current user or
if that is not set in the user preferences, the browser time.
After you get the user time zone from users preferences, you can send it as
a parameter to set_time_zone() method of DateTime.
You can do it in the templates:
[% row.last_modified.set_time_zone(c.user.get('time_zone')).strftime('%F
%T') %]
(not tested, but it should work)
Don't know how to get the time zone of the user from browser, but I think it
is not possible. You might need to get the visitor's IP and use a service
that can tell you his/her country or even city, and maybe there is a module
that can translate that into DateTime time_zone rformat...

If your users have an ID, they're probably logged in. If they are logged in,
you can get and use that ID in your app by getting it with:
my $user_id = $c-user-obj-id
or
my $user_id = $c-user-get('id');
(And the second way is recommended).

Re: [Catalyst] Where is the form field lost?
From: Charlie Garrison garri...@zeta.org.au One of the reasons I found IC::FS so much better, was the extra control for things like how files are named/stored on disk. From the POD: fs_file_name Provides the file naming algorithm. Override this method to change it. This method is called with two parameters: The name of the column and the column_info object. _fs_column_dirs Returns the sub-directory components for a given file name. Override it to provide a deeper directory tree or change the algorithm. That's true, but I still don't know how can I store the path to the file. If in the file field I store just the file name, I need to create a second column just for storing the random path for each file upload field. If I will store the random path and the file name in the same column like /e3/e3434ae1b/The original file name.pdf then each time I would need to create a subroutine that takes this file name and gets only the original file name for printing it on the page, but I think this is the most simple way though.

[Catalyst] Where is the form field lost?
Hi,
After sending a form with a file upload field, that field is lost if no file
was attached, just like when the form doesn't contain that file upload field
at all.
I have tried to check Catalyst, Catalyst::Request, Catalyst::Engine,
HTTP::Body and HTTP::Body::MultiPart in order to find where are the file
upload fields lost, but I
couldn't find it.
I need to know if the form didn't have a file upload field, or if it had it
but no file was uploaded.
I have printed Dumper $request-_body in Catalyst::Engine::prepare_uploads,
and when a file is uploaded, it looks like:
$VAR1 = bless( {
'content_length' = '1727',
'tmpdir' = 'C:\\DOCUME~1\\Octavian\\LOCALS~1\\Temp',
'part' = {},
'buffer' = '',
'state' = 'done',
'chunk_buffer' = '',
'body' = undef,
'content_type' = 'multipart/form-data;
boundary=---7da8c3070458',
'length' = 1727,
'boundary' = '---7da8c3070458',
'chunked' = '',
'upload' = {
'file' = {
'headers' = {
'Content-Type' =
'text/plain',
'Content-Disposition'
= 'form-data; name=file; filename=E:\\_cool.txt'
},
'tempname' =
'C:\\DOCUME~1\\Octavian\\LOCALS~1\\Temp\\PrJ0ruNzzR',
'name' = 'file',
'size' = 44,
'filename' = 'E:\\_cool.txt'
}
},
'param' = {},
}, 'HTTP::Body::MultiPart' );
If no file was uploaded, it prints:
$VAR1 = bless( {
'content_length' = '1699',
'tmpdir' = 'C:\\DOCUME~1\\Octavian\\LOCALS~1\\Temp',
'part' = {},
'buffer' = '',
'state' = 'done',
'chunk_buffer' = '',
'body' = undef,
'content_type' = 'multipart/form-data;
boundary=---7da1573870458',
'length' = 1699,
'boundary' = '---7da1573870458',
'chunked' = '',
'upload' = {},
'param' = {},
}, 'HTTP::Body::MultiPart' );
So the 'upload' key doesn't contain anything, not even the name of the file
upload field.
Can you give me a hint where I should look for finding where the empty file
upload field is skipped if it is empty?
Thank you.

Give your upload field(s) a name like upload_1 and then see if it

I gave it the name file, but if the file is not uploaded, it doesn't
appear in uploads(). (I hope file is OK as a name, no?)
Can you give me a hint where I should look for finding where the empty

upload field is skipped if it is empty?
That's how HTTP::Body works. If there's a filename, which there is with
upload fields, but the file name is empty, then it's skipped.
Aha, so I should look better in HTTP::Body.
Is there a reason it does that? (Leaves alone all other empty form fields
but deletes the empty file upload fields?)
if ( exists $part-{filename} ) {
if ( $part-{filename} ne ) {
$part-{fh}-close if defined $part-{fh};
delete @{$part}{qw[ data done fh ]};
$self-upload( $part-{name}, $part );
}
}
BTW -- I think that delete of fh should not happen (and the temp file
should be set to unlink on destroy). Otherwise you can end up with
orphaned
temp files.
And I think it should also returned the empty file upload field as an empty
upload field, and not delete it at all.
I think this change cannot cause errors in other places.

Re: [Catalyst] Where is the form field lost?
Hi Stephen, From: Stephen Howard step...@enterity.com I believe your problem lies in the browser itself. I know, for example, that browsers do not send empty values for checkboxes that remain unchecked - they simply eliminate that field from the form submission altogether. Sounds like file fields might be the same way. Your best bet is to use a bit of scripting on the browser side to mark a hidden field to stand in for the empty file field. - Stephen I have verified that, and the browser sends the empty upload field, with no content, like: -7da3d8a106ce Content-Disposition: form-data; name=file; filename= Content-Type: application/octet-stream -7da3d8a106ce So after the MIME header there is no content, but the header with the name of the field (file) is sent to the server.

Re: [Catalyst] Where is the form field lost?

orasn...@gmail.comwrote:
Give your upload field(s) a name like upload_1 and then see if it

I gave it the name file, but if the file is not uploaded, it doesn't
appear in uploads(). (I hope file is OK as a name, no?)
Why do you need to know that a field existed on the form but was submitted
empty? Checkboxes don't submit if not checked. You get what's included
in
the post and have to work from that. Either you have an upload or not,
right?
I made a InflateColumn::FileUpload inflator similar to InflateColumn::File,
which also works with HTML::FormFu and it has an additional feature.
The files can be uploaded by just using:
sub add : Local FormConfig {
my ($self, $c) = @_;
my $form = $c-stash-{form};
if ($form-submitted_and_valid) {
$form-model-create;
#Print the success message and redirect here
}
}
And the existing record that contains file uploads can be also modified by
using:
sub edit : Local FormConfig {
my ($self, $c, $id) = @_;
my $form = $c-stash-{form};
my $record = $c-model(DB::TableName)-find($id);
if ($form-submitted_and_valid) {
$form-model-update($record);
# Here print the success message and redirect
}
else {
$form-model-default_values($record);
}
}
In the Result::TableName there should be:
# If the user might need to replace the existing uploaded file with another
one:
__PACKAGE__-mk_group_accessors(simple = 'file_replace_validator');
__PACKAGE__-load_components(InflateColumn::FileUpload);
__PACKAGE__-add_columns(
file, {
data_type = VARCHAR,
default_value = undef,
is_nullable = 1,
size = 255,
is_file_upload = 1,
file_upload_path = $ENV{the_directory_where_the_files_will_be_stored},
});
The form used to add new records will contain a common HTML::FormFu File
element (and other elements needed).
The form used for editing can contain a checkbox with the name
file_replace_validator, or if the name of the file upload field would be
foo, that checkbox will be named foo_replace_validator. I created an
accessor for it because there should be no column with this name in the db
table (although I may find a solution to not need it at all).
When the user will use the form for creating a new record, it will upload
the file if a file is loaded in the form, or it will send the form without
that field so here there is no problem.
When the user will use the editing form, he or she will have the option of
choosing if she wants to replace the existing file.
If she doesn't check that checkbox, it doesn't matter if she uploads a file
in that field, because the original file won't be changed.
If she checks it, it means that she wants to replace the existing file with
the new file uploaded. If she checks it but she doesn't upload any file, it
means that she wants to replace the existing file with nothing, so she just
wants to delete the existing file.
So with this inflator one can upload a new file, delete an existing file,
and replace an existing file with another one by using just 2 forms which
are the same, but the editing form may have that aditional checkbox for
confirming the replacement.
If the user will delete the record, the file attached will be also deleted
from the disk.
If the user will access the record, it will get a hashref with 2 elements -
the filename, and the IO::File handle to that file so she will be able to
use the same syntax as the InflateColumns::File does it:
a href=[% c.uri_for('/static/path_to_dir', row.id, row.file.filename).path
%][% row.file.filename | html %]/a
The problem is that if DBIC doesn't find any file upload field, the inflator
is not used at all, so it doesn't do anything, although it should see that
there is an empty file upload field that has the is_upload_file attribute,
see that the user has chosen to replace the existing file with it,
so it should delete the existing file.
For making it work, I need to add the following ugly code in the edit
action:
if ($form-submitted_and_valid) {
#Set a hashref for the empty file field because otherwise FileUpload
inflator ignores it
unless ($form-param('file')) {
$c-req-params-{file} = {};
$form-process;
}
$form-model-update($anunt);
#...
}
I didn't want to load this inflator to CPAN until I solve this issue, but if
you or somebody else wants, I can send you the source code.
Without commends in the code or documentation can't really know the
author's
reasoning. I guess it assume uploads go to temp files and no need to do
that if there's no content.
If the file is an empty one, I guess there shouldn't be a big issue if the
file would go to the temp directory. I think it could get deleted as the
other non-empty files which are uploaded there.

Re: [Catalyst] modules for conditional GET ?
From: Dami Laurent (PJ) laurent.d...@justice.ge.ch Hi Catalysters, For some actions of a Catalyst app, I would like to implement conditional GET (using If-Modified-Since HTTP header), where the timestamp of one config file decides whether the page should be refreshed or not --- this is because that page is quite expensive to compute. This scenario sounds like a common thing to do, so I expected to find some Catalyst plugins/extensions in CPAN to do that, but didn't find any. Did I just miss some CPAN modules, or should I really start from scratch ? Thanks in advance for any hints, Laurent Dami Try Catalyst::Plugin::Cache::HTTP.

Re: [Catalyst] Various ways to use c.uri_for
From: Kiffin Gish kiffin.g...@planet.nl
I noticed that in certain examples depending on the coder, sometimes the
following format is used:
c.uri_for(c.controller('Users').action_for('list'))
and other times this fomat:
c.uri_for('/users/list')
What's the difference and is there an advantage of using one or the
other?
Thanks alot in advance.
--
Kiffin Gish kiffin.g...@planet.nl
In the first case you can provide the name of the action and not the URL
that dispatches to it.
The advantage of the first one is that you may want to change the way the
URL looks like and in that case those links will work.
For example, say that you have the following action:
package MyApp::Controller::Users;
sub lst : Path('list' {}
You can access the lst action by using the following:
c.uri_for('/users/list')
and
c.uri_for(c.controller('users').action_for('lst')
In the future, if you will want to change some things and access the list of
users with an URL like
/users/something-else
the first way won't work, and you will need to check all the templates and
change it, while the second will work fine, and it will generate the correct
URL to the action lst.
It could be helpful to have shortcuts for the second way of creating URLS,
something like...
c.url_query('controller_name', 'action_name', param1, param2)
We can put a url_query subroutine in MyApp.pm that looks like the one below
(although I don't know if it works in all the cases - chains), but it could
be helpful to have such a thing in the core:
sub url_query {
my ($c, $controller, $action, @params) = @_;
return $c-uri_for($c-controller($controller)-action_for($action),
@params)-path_query;
}

That column is automaticly inflated by the component InflateColumn::DateTime
which is loaded above by:
__PACKAGE__-load_components(InflateColumn::DateTime, Core);
so that column is a DateTime object and you can use the DateTime methods
like:
$row-last_modified-ymd
$row-last_modified-set_locale('fr')-strftime('%e %b %Y')
...
If you want, you can disable the inflation by adding (after do not modify
this or anything above'):
__PACKAGE__-add_columns(
last_modified = { data_type = 'datetime', inflate_datetime = 0 }
);

Imagine the following code in one of your actions:

my $result = [ $c-model( 'Foo' )-search( {

From: J. Shirley Trusting Google to give you the latest version is probably a pretty bad idea :) To derail this conversation a little bit, perhaps the canonical meta tag pointing to the most recent release would do well on older versions still sitting on CPAN? I'm not sure how else to coerce Google into always linking to the most recent version of whatever it finds. That, and the Latest Release on CPAN is busted. It points to 5.7003 which then goes to a Not Found page. Ick. There could be a permalink to the latest version on CPAN, and a program that handles the 404 Not Found errors which could get the module name (without version) and redirect to that permalink. This way, if the older versions are removed from CPAN, the Google always would return the latest version of the found module.

class definition, because the data from that column might be presented in
different languages, for different locales.
In the POD documentation of DBIx::Class::InflateColumn::DateTime I've
learned how to set the locale for the date columns, but only by setting it
in the class definition.
I've tried to set it when I used it, like
$class-date_field-month_name(locale = 'ro_RO')
or
$class-date_field-month_name({locale = 'ro_RO'})
with no luck, of course.
Thank you for any hints.

IMHO this is something the view should handle. The model's output should
stay the same regardless of which locale the user has.
What view classes are you using? I usually write a TT macro which sets
the locale and/or timezone to the user's preferences.

I found that I can use
$class_name-date_field-set_locale('ro')-month_name
I found that the last version of the Catalyst DBIC::Schema helper adds
InflateColumn::DateTime component by default, and until now I was using a
raw date like
[% row.date %]
and it printed a date like 2009-04-24.
Now it prints it as 2009-04-24T00:00:00.
I wanted to correct this and this is how I became interested about also
localizing the dates.
Thanks.

Re: [Catalyst] RFC: Sample press release and announcement homepage
From: John Napiorkowski jjn1...@yahoo.com ... the revolutionary Moose Object system, the most advanced Object Oriented framework for any major scripting language I would change that to 'one of the most advanced' - less flame igniting (and by the way Perl 6 probably does have a more advanced Object system). I really want to agree but then I read some of the crazy hype coming out of pretty much every other system and I ask myself if our modesty hurts us? I mean I'd rather go to the mat and try to argue Moose is the best thing ever and stir some controversy than to keep being ignored as we have been. Any other thoughts or feelings? My first version of this was even more strongly worked, but I toned it down a bit. Still, I figured at least one person would call me out on one or two bits. I'll mellow it out if people think I should. You can say that Moose is the best, but in that case I think it would be elegant (and helpful) to also say why. If we don't even know if it (and why) it is the best... I think you should not tell that.

Re: [Catalyst] Using JSON
Ok, thank you all for your recommendations. So C::V::JSON would be the way to go for creating JSON and C::C::REST for creating/parsing. I don't know yet if I would need to parse JSON if I use JQuery because I've seen that it can get the data in JSON format, but it sends the requests to the server in the standard CGI format using var1=valu1var2=value2... so I might not need to parse JSON but just to create it. Anyway, now I know which would be the right way of creating JSON too if I would need it.

I knew that it should be the prefered method for the forms that don't change anything on the server, like a search form. Isn't this true?

Re: [Catalyst] Thoughts On GeoIP Modules?
From: Andy Dorman ador...@ironicdesign.com The problem so far is manual sign ups for accounts that are then abused. And in analyzing what happened we have noticed that many of the abused accounts were signed up from one or two countries. We think that geoIP restrictions could cut our abused account sign ups in half at least. This would also ban the good users, but those who want to continue abusing would be able to use an anonymous proxy from another country.

Re: [Catalyst] RFC: The paradox of choice in web development
From: Ali M. tclwarr...@gmail.com When Catalyst is not chosen I personally believe it the combination of two things 1. Perl is no longer perceived as an easy language, or language that make development easier. More exactly,, Perl is considered a language hard to learn, that creates a code hard to maintain, a language that uses a strange OOP style (because I guess there are no books for Perl beginners that teach about Moose or Mouse), a language which is too flexible and because of this it is not prefered by the large teams of programmers because each of them could have a different style. 2. Catalyst perceivably doesn't offer enough added value for developers who are not that much into Perl to make the sacrifice and use Perl anyway. If the programmers are not that much into perl, this means that they don't know how to use DBIx::Class and Catalyst and possibly other few modules which are usually used by Catalyst developers, and in that case they can't understand the power of Catalyst. If Catalyst wants to compete with RoR or other frameworks, it should be as easy to install as those frameworks, and the simple apps should be also very easy to create. The comparisons between web frameworks are not based on the number of the requests they serve, or on the number of database tables they manage, or on the number of backend servers they are installed on, but on the number of web sites that use those frameworks, so those comparisons might show that there are 100 sites that use RoR and only 5 that use Catalyst, but don't tell that 3 from those 5 sites that use Catalyst have 3 times more visitors than all those 100 sites that use RoR. And of course, the conclusion is that RoR is much better. I think that the success of other languages, especially Python is also due to the fact that they support better Windows than Perl. WxPython is better developed than WxPerl, there are even screen readers that interact with the GUI of the OS in Windows and Linux, and finally... the number of programmers for Windows is bigger than the number of programmers for Linux. Most Perl programmers use to consider good to publicly despise Windows and those who use Windows, and also consider that Perl is a language for the web, while those who use Python or even Ruby consider them very good languages for creating programs with a desktop GUI. PerlScript as a client language, or one which is used in .hta applications or Windows Scripting Host, is pretty hard to use if we compare it with VBScript or JScript, and even if we can say that Perl can be used in places where other languages can't be used, practicly it can't be used really successfully. Of course, there are no manuals or training materials for using PerlScript, which are newer than 7 or 8 years. Even on Symbian, Python is better developed than Perl, which practicly I don't think it is really used on the mobile phones. I've seen a few persons that say that yes, there are many perl developers that create modules for CPAN, which is great, but the core Perl development team is probably very thin, Perl 6 is not ready yet, while Python 3 was launched and it has a great and powerful core team. Python is sustained by Gmail and Sun, which create programs that use it, but Perl, even though it is used by big companies like Oracle, just use it, and don't seem to sustain its development. I think these disadvantages also influence the potential users to think that even the Python frameworks are better, which is not true.

Re: [Catalyst] HTML::FormFu form elements
From: Greg Coates gcoa...@csuchico.edu
I've run into a scenario where I need to be able to build an
HTML::FormFu form and then only display portions of it in my template.
(So, the typical [% form %] in the template will be replaced by
something else, at least in my ideal world.)
I tried doing this in the template:
[% form.get_element('name' = 'element_name') %]
I didn't get an error, but it didn't display.
Does anyone know if what I'm trying to do is possible, and if so, how to
do it?
Thanks,
Greg Coates
Can't you just split the form configuration file in more files, and create
another configuration file that loads all those parts?
When you will need the entire form you could load the form configuration file
that loads all the parts, and when you need just a part of the form, you could
load the configuration file that contains that part only.

Re: [Catalyst] Proper ngettext with Catalyst
From: Felix Antonius Wilhelm Ostmann ostm...@websuche.de i run into the same problem with german phrases [quant,_1,message has,messages have] been sent. but in german: singular: Es wurde 1 Nachricht gesendet. plural: Es wurden 10 Nachrichten gesendet. So i cant build that with normal quant ... and i was thinking about a quantf :) Es [quantf,_1,wurde %d Nachricht,wurden %d Nachrichten] gesendet. That would also fit for other languages where words get shuffled for different counts, right? And you can use quantf only in that languages that need that. Others can still use normal quant. In Locale::Maketext I read that for more complex cases, the quant() method could be overriden. But making a quantf() method could be very helpful and it could also allow commify the number using the tools offered by Locale::Maketext.

Re: [Catalyst] Proper ngettext with Catalyst
On Sat, Jan 31, 2009 at 8:29 AM, Nikolai Prokoschenko b. is wrong semantically, since plural form count is different in different languages and the position of a word can differ depending on the number (this is one reason why gnu recommends translating complete sentences) I didn't know that. Do you say that in some languages they say something like: I have 1 apple. and I have apples 10. (or 10 apples I have.) If this is true, then yes, maketext's way is not good.

Re: [Catalyst] Proper ngettext with Catalyst
From: J. Shirley jshir...@gmail.com Most east-Asian languages don't have the same concept of plurals. You don't add the s, so it would just be I have 1 apple or I have 10 apple. This is not an issue, because for the japanese translation, the string could be something like: I have [quant,_1,apple,apple] But the problem would appear if the position of the words is different depending on plural/singular. So if we would need to write: singular: I have 1 apple. plural: I have apples 10. then we can't use maketext. Or maybe in certain languages we need to use: I have apple 1. I have apples 10. and then I don't know how maketext could deal with this. It could use something like: I have [quant,_1,apple,apples,,reverse] Or another keyword than reverse could be used, for example rtl and the default could be ltr. So a poe file for a rtl language could contain something like: msgid I have [quant,_1,apple,apples]. msgstr I have [quant,_1,apple,apples,,rtl]. Of course, between those 2 commas, we can put no apples if we need. If gettext allows using msgid_plural (I didn't know about it), it is more flexible than maketext, but it requires some more to type.

Re: [Catalyst] Proper ngettext with Catalyst
From: Kieren Diment dim...@gmail.com In indonesian, to pluralise you just say the word twice, or in writing put a 2 after it. I have two apples: Saya ada dua appel appel. or: Saya ada dua appel2 Saya ada [quant,_1,appel,appel appel]. But it doesn't do a perfect translation this way, because instead of dua it just puts 2, which is not very nice in some languages. For example, in Romanian some numerals depend if the noun is masculine or feminine: 1 is unu for masculine and una for feminine nouns. 2 is doi for masculin and doua for feminine nouns. And it also depends for 21, 22, 31, 32, and so on, but these bigger numbers are usually written as numbers because they are too longer otherwise. For 1 and 2 however, in many cases they are written as words because it is much clear. Another problem is the case of 0 because in English is easy but in other languages the structure of the sentence is totally different. For example: I have seen 1 boy. I have seen 2 boys. I have seen no boys. But in Romanian it should be: Am vazut 1 baiat. Am vazut 2 baieti. Nu am vazut nici un baiat. Of course, in English works but it is not very nice either. It should have been I haven't seen any boy or something like that.
