Right.
If you need more help about DBI, dbi-us...@perl.org is a better place to
ask.
Not that we catalyst users are not willing to help you, but most people
here know much about Catalyst, and not-as-much about DBI.
Feel free to ask your DBI questions here, but if it comes to DBI
details, the people reading dbi-us...@perl.org are, well, more
qualified. The chance to get helpful answers (or any answers at all, for
more special/difficult questions) is much higher if you post to the
right list...

Hi Craig,
Using C::M::DBI is straight forward. Install it from cpan, and run
script/yourapp.pl create model DBI DBI dsn user password
where "dsn" is sth like "dbi:mysql:dbname", depending on your backend.
If it doesn't work you most likely have some typo in your dsn, username
or password.
When this doesn't work, what error is printed?
What was your input (except passwd, of course)?
Something like $c->dbh doesn't exist. The database handler belongs to
the model, and you can create Cat applications with several models, or
without any model at all. (Or with a model which is not a
database-model, or, or ...)
$c->model('DBI')->dbh does the trick.
The name "DBI" is required by C::A::Store::DBI, but besides this, any
model name is fine.
Alternatively, add a shortcut to your main App.pm:
sub dbh{ shift->model("DBI")->dbh }
Now, $c->dbh is available.
Session timeouts et cetera are configurable in the session plugin.
The session keeps track of when it was created, and when it was updated.
Setting extra fields (in the session or in the database), which are not
automatically set by the authentication plugin, can easily be done by
you, even if you use a authentication plugin. You can do this in the
"auto" action, for example.
I can only suggest you to search for existing modules, and use them
whenever possible. Thanks to Moose, extending a catalyst module is easy
in most cases. And it is much less work than writing everything from
scratch.
In my opinion, the biggest benefit of catalyst is (besides its great
backwards compatibility), that it is very modular, dozens of modules
exist, and most modules are extendable and reusable.
If you try to write all your code by yourself, you will not get happy.
Another suggestion: Maybe you should first forget about your real
applicationfor now, and just work through the catalyst tutorial. You can
finish it in some hours (depending on your perl- and web knowledge).
It will give you a great overview about how Catalyst works, what is
possible (almost everything) and what isn't possible (almost nothing) :)
Or maybe you don't need a monster like catalyst? "Dancer" might be an
option.
Dancer is a perl MVC Framework, too. It is much smaller and simpler than
Catalyst, has less dependencies and less modules and (at least I was
told so) is easier to learn. It does not do as much for you as catalyst
does (in most cases, you have to write more code). But if you have to
reinvent the wheel again and again anyway, it might be a better choice.
Don't get me wrong. I don't suggest you to let catalyst go. Catalyst
rocks! But if most of the benefits are really not an option for you, you
should think about alternatives.

This was what I thought and am trying to avoid, I am doing my best to keep
concern with SQL trot he Model and any action/method that requires data to use
the Model and have the business logic kept in the Model, so that only
actions->routes and the additional application helper methods are in the
controller.
I have read and seen frameworks such as Mojolicious encourage a shrinkage of
the Model and move alot of functionality to the Controller, so there is a
paradigm which seems to imply it is ok to do more stuff in the Controller, but
I am leaning towards having the main code in the Model and then bolting it
together via the Controller.
So for example the authentication for the user is in the Controller but it
simply utilises the Model
EG.
sub AuthenticateUser {
my ( $self, $c ) = @_;
$c->session;
if(!$c->model('Members')->LogCheck($c)){
$c->forward('/login/login');
}
}
Dunno, this is all new to me and I'm refactoring as I go, so I doubt I'll get
it right first time! Does anyone?

Just a small FYI more than anything, which might help fill in a few gaps...
$c->dbh would need you to modify MyApp.pm, this is useful at times for
creating little helper methods that you want accessible via $c, or to
override existing $c methods.
The session plugin does this too, that's why $c->sessionid is available,
etc. or $c->check_user_roles() when using the Authorization::Roles plugin.
I'm not sure you'd really want $c->dbh anyway, since that's doesn't
sound like you would be encapsulating the Model very well, and sounds
like you'd have SQL in your controller code?

There's no black-magic going on, so your AuthenticateUser() sub never

In short, you'll only get $c when using the method attributes, such as

Right, that's not the case. It only passes to the :Chained or :Args or
:CaptureArgs methods. This leaves you free to create your own internal methods
that don't get extra $c args interfering with your logic.

Re: [Catalyst] Why is $c undefined?
Hi again,
$c is automatically passed to Catalyst-actions (not methods), but only
if you use Catalyst to do so.
If you call
$self->someaction;
or
$c->controller('SomeController')->someaction();
it is not passed. How can catalyst know if you are calling a catalyst
action, or any method on any object? And even if the object is a
catalyst controller, how can catalyst know if it is a action, which
requires the context, or just a helper, which doesn't use the context?
If you want catalyst to pass $c, use $c->forward, $c->detach, $c->visit
and $c->go instead:
$c->forward("/someaction");
or
$c->forward($c->controller('MyController')->action_for("someaction"));
or
$c->forward("/somecontroller/someaction");
Read the main catalyst docs for details. (perldoc Catalyst)

RE: [Catalyst] Why is $c undefined?
Cool, thanks.
Reading the tutorial I got the impression $c was always passed.
Thanks for clearing that up, which is why I guess $c->dbh doesn't exist.
hmm, much for me to get my head round for sure!

There's no black-magic going on, so your AuthenticateUser() sub never

In short, you'll only get $c when using the method attributes, such as

RE: [Catalyst] Unable to output anything in Root.pm -> 'auto'
Hi Lukas,
I tried to use C::Model::DBI , but I cannot get it to work?
I've ended up refactoring my own SQL module from the exisitng app as OOP and
then as an extension of Catayst::Model
I then create my own Model which extends my SQL module and I've got it working.
No matter what I tried , I couldn't find $c->dbh , I really seem to be
struggling at the moment getting my head round Catalyst, but I am persevering!
I was hoping to use the built in DBI functionality, as it is meant to keep
database handles / connections open etc..but $c->dbh didn't exits in my Model
when I created it via myapp_create.pl MODEL DBI
I also appreciate there is a lot of stuff already written such as the
authentication mechanism, but will that update my backend DB with the current
location of the user?
Does it have a mechanism to enable 'heartbeat' to keep idle sessions open?
Will it keep up-to-date the date / time field so we can see at a glance the
length of time a user has been logged on via our admin system?
Or does it simply keep a state of whether the user is loged in or not?
I also know that I should look at ORM and DBIC, but one thing at a time, Rome
wasn't built in a day, and playing with Catalyst is simply something I want to
do, not a requirement of my Job.
I start a 10 month SQL course in January, where I'm sure I will learn about
DB's in far more detail and can then consider ORM / DBIC.
There is only so many hours in the day, then there are only so many I am paid
to work and then there is only so much information I can absorb in one go!
I'm already sitting here doing unpaid overtime, but I'm commited to getting
Catalyst working, so don't mind putting in the extra hours, sounds sad I know,
but I am enjoying it, even if I seem frustrated at times.
Thank for all the input.
Craig.

Subject: Re: [Catalyst] Unable to output anything in Root.pm -> 'auto'
Hi Craig,
You are NOT wrong. Catalyst allows you to do so. I think it is the right
choice.
For C::A::Store::DBI - What you need is to provide the user_table,
user_key and user_name, and the password_field and password_type for the
credential part. I guess you have this, haven't you?
All the "role" stuff is optional and only required if you want to use
Catalyst::Plugin::Authorization::Roles (which you don't want if I got
you right).
I would suggest you to use as much existing code as possible, and only
rewrite what you really need.
In your case:
Use C::A::Store::DBI for authentication and C::Model::DBI to access your
database.
If you do so, you only have to write your own authorization code (roles
etc) and your CRUD stuff. You can access your db using DBI, without ORM
or any assumptions to the db layout.
If you can not use C::A::Store::DBI for any reasons, I would still
recommend you to either write your own Catalyst::Authentication::Store
and/or Catalyst::Authentication::Credential modules (I guess a
Store-module will do the trick). You will not have to deal with
user-sessions and related stuff. Just tell Catalyst how to authenticate
the user, and let catalyst itself deal with the session.
Catalyst::Plugin::Authentication::Internals tells you how to write your
own store and credential modules. You will have to read the docs first,
but I am sure that this is less work than writing ALL your
authentication, session handling and authorization code by yourself.
When it comes to reusability, Catalyst is unbeatable :)
If you want or need to write your own authentication code in your
controller classes, you should still use $c->session directly. Don't
fiddle with the session id. Doing so is error-prone, and not required.
You can do it like this:
unless(defined $c->session->{user}){;
my $user = your_auth_code(\%data);
$c->session(user => $user);
}
You can later access it in any controller by saying:
my $user = $c->session->{user}
You can even make a shortcut in your App.pm:
sub is_authenticated{ defined( shift->session->{user}) }
And later check if the user is authenticated like this:
if($c->is_authenticated){
do_some_privileged_stuff();
}
You should consider using DBIx::Class anyway. It doesn't require
normalized databases. Automated model generation might not work
correctly, but in general you can use it on any database. DBIx::Class is
well documented, easy to learn, and it makes database access simple and
safe. Without ORM, you will most likely have to write 10 times more
database-code, and you will have to double check it to ensure that you
are not vulnerable to sql injections.
You are not forced to use DBIC relationships et cetera. You can just use
it to update your tables, and only use the rels where you have them in
your db layout.
In my opinion, the reasons not to use DBIC are:
1: it takes some time to install, but you only have to do it once.
2: it s

In my opinion, the reasons not to use DBIC are:
1: it takes some time to install, but you only have to do it once.
2: it slows down the startup time for your application, but unless you
are using plain CGI, this doesn't really matter. (If you use
plain-old-CGI, STOP doing so. Use FastCGI instead.)
3: It sometimes generates more SQL statements than it is required to
fulfill a certain task, but this is only relevant if you are running a
high performance, high traffic site. And IF this is the case, you can
still optimize it.
If you compare it to the benefits I described above, the benefits are
dominant in most cases.
I know that this is not the universal truth (which doesn't exist
anyway). It is my personal opinion. Just think about it.
Additionally: DBIC makes moving from one database system to another very
very easy. You have a SQLite DB, and want to move to Portgresql?
no problem. With DBIC, you are already done :)
Ok. I hope I could help.
Sorry for the DBIC-praising at the end. It is just that I first didn't
want to use DBIC, too. And now I see how much easier my life is with
DBIC, and I think I should have moved to DBIC earlier.

Hi Luka,
Perhaps I miss-read the info on
http://search.cpan.org/~janus/Catalyst-Authentication-Store-DBI-0.01/lib/Catalyst/Authentication/Store/DBI.pm
But from what I can see it expects you to map specific fields in a table as
well as have a user role table with specific data mapping?
[quote] __PACKAGE__->config->{'authentication'} = {
'default_realm' => 'default',
'realms' => {

Have I read the above incorrectly?
I have a non-normalised DB , with an application that functions in a particular
way, I deal with user roles and other such stuff in my own way and I cannot
refactor to use catalyst without ensuring all sections of the system function
the same along with the back end admin system, I can't rewrite both parts at
the same time, this is a live app in production that works currently, I'm
simply trying to learn Catalyst & MVC cuteness, not start from scratch.
>From what I can see using any of those authentication modules expects certain

Please correct me if I'm reading the CPAN documentation incorrectly.
I want to refactor my app to be MVC using Catalyst without being forced to do
any other than MVC cuteness and work the way I want to with the a database that
already exists, I got the feeling Catalyst allows this unlike ROR or other MVC
frameworks.
Again, have I got this wrong?
If to use Catalyst I have to have a normalised DB, use specific modules with
data in a particular format, then I will just refactor our systems myself using
my own modules and such, best to find this out now before I spend any more time
on something that isn't suitable.
Thanks,
Craig.

Hey Craig,
I got it. You want to store your credentials in a database, but you don't want
to use DBIx::Class?
What about Catalyst::Authentication::Storage::DBI?
If this doesn't help, you might me right. Maybe you have to write your own
authentication module. In that case, consider making it a
Catalyst::Authentication::Store module, and publish it on cpan. It might be
useful for others, too...
By the way: Catalyst::Model::DBI is a ORM-less, raw DBI model for catalyst. So
"... whenever I look at how it implements anything to do with DB access, it
forces ORM upon you ..." is not correct. There are very few things which are
really forced by catalyst. Using DBIx::Class is just considered "good
practice". A lot of people use it, thats why it is used in most tutorials and
examples.

I guess there is something for you: Examples: Catalyst::Authentication::Credential::Remote -> let the webserver do authenticaion Catalyst::Authentication::Credential::HTTP -> basic and digest authentication Catalyst::Authentication::Store::Htpasswd -> use catalyst authentication with htpasswd-files Or you use Catalyst::Authentication::Store::Minimal, and populate the config hash within "finalize_config" (If you want to store accounts and passwords in a file, which has no standard-format.

"By the way, what do you need the session-id for? Catalyst handles sessions in
a transparent way"
To authenticate users, I don't want to store authentication in the hash and it
seems the only other way to do this is via ORM, which I don't want to use
either.
I find catalyst whenever I look at how it implements anything to do with DB
access, it forces ORM upon you, so I need to write my own authentication code
don't I ?

Hi again,
about the missing sessionid:
I don't know much about the internals of Catalyst::Plugin::Session, but I guess
that the session is a lazy attribute, and only created if used.
This means: unless you put something in the session, you will not have one, and
therefore have no session-id.
This is very handy, because the overhead related to creating and restoring a
session is only executed if the session is really needed.
If your app has a session-less interface without authentication, and extra
functionality for authenticated users, the session will only be created for
authenticated users.
If you touch your session object before fetching the session-id, it will
work:
$c->session;
$c->res->body("SESSIONID " . $c->sessionid);
As soon as you implemented authentication, the session will be used and the
session-id will be set.
By the way, what do you need the session-id for? Catalyst handles sessions in a
transparent way. In most cases, you don't need to access the session-id in your
code. And if it is only for debugging: The session plugin writes the session-id
to $c->log when a session is created or restored. This means: the code showed
above will result in the session-id being printed twice :)

RE: [Catalyst] Unable to output anything in Root.pm -> 'auto'
OK, thanks.
I assume you meant 'comment' not 'uncomment' , which I did and it now outputs
what I wanted!
Though $c->sessionid is still blank?

Hi Craig,
Take a look at the default "index" method in Controller/Root.pm.
If you look at the debug output, you will see that "index" is called after
"auto". Index sets, and therefore overwrites $c->res->body.
If you use a template system, the default "end" action
(ActionClass:RenderView) will only render the template if $c->res->body is not
set. But setting the body directly, as in "index", will overwrite any
previously added content.
Uncomment the line '$c->response->body( $c->welcome_message );' in 'sub index
...', and you will see whatever you write to $c->res->body in "auto".
Cheers, Lukas

Hi Craig,

Uncomment the line '$c->response->body( $c->welcome_message );' in
'sub index ...', and you will see whatever you write to $c->res->body in
"auto".

RE: [Catalyst] Unable to output anything in Root.pm -> 'auto'
Oh I also tried changing it to ‘begin’ instead of ‘auto’, still doesn’t work?
I also thought that all calls to ANY method / sub will always be passed $self &
$c , only it doesn’t seem to be passing in $c and I’ve had to manually do it?
I’ve tried…
# always runs first!
sub begin :Private {
my ( $self, $c ) = @_;
# Authenticate
$self->AuthenticateUser($c);
return 1;
}
sub AuthenticateUser {
my ( $self, $c ) = @_;
die 'Session ID = ' . $c->sessionid;
}
But there is no session ID.
I am still getting the “Use of uninitialized value in concatenation (.) or
string” error.
I’ve read
http://search.cpan.org/~mramberg/Catalyst-Plugin-Session-0.14/lib/Catalyst/Plugin/Session/Tutorial.pod
Where it states : These plugins will automatically set $c->sessionid at the
begining of the request, and automatically cause $c->sessionid to be saved by
the client at the end of the request.
So why is $c->sessionid uninitialized?
Any ideas where my session info is?
Thanks,
Craig

[Catalyst] Unable to output anything in Root.pm -> 'auto'
Hi,
I seem to be going round in circles unable to get Catalyst to output anything
via 'auto'?
I made a change to the Root.pm to try to add authentication via the 'auto'
method, but it does nothing?
# always runs first!
sub auto :Private {
my ( $self, $c ) = @_;
# Authenticate
$c->response->body('Matched Members::Controller::Auto in Root.' .
$c->sessionid);
}
This doesn't output anything and I simply get the welcome screen, plus there is
a warning in the devel server output of
"Use of uninitialized value in concatenation (.) or string"
I have ..
use Catalyst qw/
-Debug
ConfigLoader
Static::Simple
StackTrace
Session
Session::Store::FastMmap
Session::State::Cookie
/;
In my main MyApp.pm
Why is $c->response->body not working and why is the sessionid empty?
Thanks
