[Catalyst] Catalyst::Plugin::Authentication w/ multiple stores
Hi everyone, I am resending this previous post from December because I got no replies - maybe it was the Xmas thing, maybe I'm just stupid. Do the Catalyst::Plugin::Authentication developers or anyone using Catalyst have any idea... (see below) -- original post -- Does anyone know how to configure Catalyst::Plugin::Authentication with multiple stores? The docs are very ambiguous on this and when I follow them as best I can it doesn't work. I use C::P::A::Store::LDAP as my first store and try to authenticate users with that but I would like Catalyst to also try a secondary store, C::P::A::Store::DBIC, if the user doesn't exist in the LDAP tree. Am I misunderstanding C::P::A's feature of being able to use multiple stores? In MyApp.pm: use Catalyst qw/ -Debug ConfigLoader Static::Simple StackTrace Authentication Authentication::Store::LDAP Authentication::Store::DBIC Authentication::Credential::Password Authorization::Roles Authorization::ACL Session Session::Store::FastMmap Session::State::Cookie /; In myapp.yml: authentication: store: Catalyst::Plugin::Authentication::Store::LDAP stores: ldap: Catalyst::Plugin::Authentication::Store::LDAP dbic: Catalyst::Plugin::Authentication::Store::DBIC ldap: ldap_server: pdc.domain.com ldap_server_options: version: 3 binddn: cn=adsearchuser,cn=Users,dc=domain,dc=com bindpw: adsearchpassword user_basedn: cn=Users,dc=domain,dc=com user_scope: sub user_filter: ((objectclass=user)(samaccountname=%s)) user_field: samaccountname dbic: user_class: Schema::User user_field: username password_field: password password_type: hashed password_hash_type: SHA-1 Is there something incorrect here?

Re: [Catalyst] Browser window/tab independent sessions
Hi, Maybe I didn't understand well the question, but if the user wants to create a session that works only in a certain window, but doesn't work in the other windows, a simple cookie can be used if its expiry date is set to 0. This way the cookie won't be saved, but it will be memorised by the current window of the browser, and if the browser window is closed, the session ID is lost, and the user must log in again for creating another session. Same thing if he wants to use another window. Isn't this what is needed?

Putting things that are specific to a window/tab in a cookie-based session is a pet peeve of mine actually, since it can break things so spectacularly. If you check, you'll see that all of the major web sites like Yahoo and Amazon are careful to avoid this kind of issue (multiple tabs don't interfere with each other) and they generally seem to use the old-school techniques. How would I create these URI's for each window. I suppose I would have to have a 'create new window' button in the application that generated a new window with a unique window_session?

I like the lightness it gives but I've been slow to pick up because I want to be sure that pages work without js, and I haven't figured out a generic method yet. I'm sure others are ahead of me on this ... Typical scenario without AJAX : form button submits to URL, which triggers a single Cat action, which is rendered by a single template, usually of the same name. That's simple, just a one-to-one relationship. When we use AJAX, things look very similar, EXCEPT that only a part of a page is loaded. This implies that for the non-js user of the same page, multiple actions and templates have been combined so that the result is identical, even though the whole page loaded. When you say above only part of a page is loaded are you talking about the content part and not the headers, footers, and menus -- or talking about part of the content such as just a new row in a table or updating a single field in a form? It could be either ... usually some part of the content, but it could be all of it. I am talking here though about scenarios where it's more AHAH than AJAX ... the function that makes the request just sticks it as-is into the page, rather than doing some kind of decode on it. Mostly because that seems simpler, and I like simple ... Not sure exactly what you are asking for, but I'll explain what I do if that helps -- and besides I'm no fan of being warnocked. Ha ... I had to look that up, I'd not heard of Warnock before. I ask silly questions sometimes, but silly questions sometimes turn out to be useful, so I don't take it personally ... (grin) ... though I appreciate the response. I don't use that much AJAX, but I do use it for, say, displaying the next page of a list or sorting a table by a column by clicking on a column heading, or selecting a different tab to limit a table's display to a category of some type. My templates are already split up quite a bit. So, I have templates that know how to display tabs, table column headings, and how to build the table. When I update a table (e.g. next page) the same controller code is called for both AJAX and for non-ajax requests (it's the same request url) and the same template is called (derived from the controller's action name). ok ... so does the the controller know that the req is ajax? how? an added argument like ?ajax=true perhaps ... ? I use the typical TT wrapper method to build my entire page from headers, footers, banners, menus, etc. But, the TT wrapper code can detect it's an AJAX request from the request headers and knows to only build the content (i.e. the table with data I'm sorting), but not the entire page. Then my end action also knows it's an ajax request and then returns using JSON. right. so in this case there is a generic [% IF ajax %] in your template code that suppresses headers, footers and so on? which will be fine if you are getting all the content, but not part of it, I guess ? Since I use common template code for generating tabs and table headers and use the same urls for my ajax requests it's easy for javascript to search the DOM and create the events for the ajax requests. That way my HTML markup doesn't have to do anything specific for the ajax calls. That's the commonly recommended method, of course, keeping the behavior and html separate. For AJAX requests that don't update the entire page content, like an auto-complete search box, I still use the same controller as for the non-ajax request but then the controller has a little extra code to return just the search results not the entire new content -- it's just one extra line of code in most cases. Not always the most efficient method (since I end up returning more columns than is really needed for the ajax update), but so far has not been an problem. so do you typically use the same controller action, and have a flag to tell it to act differently? Of course, for updating a single field in a form (e.g. type in a zip code and city and state are automatically filled in) I use a separate controller that just handles the ajax code. In that case there's no need for an extra template since it's just updating existing markup -- the controller just returns JSON. So, I try to write as much as possible without coding specifics for the ajax calls. It's the standard recommendation to write the code for non-ajax usage, then add that behavior on page load. And, then I divide my templates into small enough parts that can be used for ajax and non-ajax calls based on how the request comes in. Thanks for the feedback. It's been enough to feed my thoughts a bit. I'll go and have a play with the code and see what comes out.

Join Chicago.pm on January 16th for an evening of Catalyst, a modern
framework for making web applications without the pain usually
associated with web development. Jonathan will be talking in-depth
about developing Catalyst applications, a topic that he knows very
well. He is a contributor to Catalyst, maintains numerous Catalyst
plug-ins, and is rumored to be writing a book on the subject.
Date: Tuesday January 16th 2007
Time: 7:00 p.m.
Where: Performics @ 180 N La Salle 12th Floor
RSVP: By noon January 15th to [EMAIL PROTECTED]
The official meeting starts at 7, but there is talk of a group getting
together before (or after) for a social. You guys can nail down the
details on that :)
Also, don't forget the Chicago.pm meeting to be held this Tuesday
January 9th at IIT in Wheaton. Andy Lester, Pete Krawzcyk, and myself
each have each picked four modules to present in a session called New
Modules For The New Year. Check out http://chicago.pm.org/ for more

Yeah, Catalyst already has an implementation for this -
package MyApp::Controller::Foo;
...
sub cancel :Action :Args(1) { ... }
then in myapp.conf
Controller Foo
Action cancel
Path /cancel
/Action
/Controller
You can apply any attribute like that, although setting Args or

Hi,
I want to conver a number to binary. I installed Math::BigInt, and get this

eventhough the installion is good. And I checked if the module installed.
There is a BigInt.pm in /lib /usr/lib/perl5/5.8.5/Math , and bigint.pm
(lowercase) in /lib /usr/lib/perl5/5.8.5
I'm not sure why I get the error.
Then, I try to plugin in the controller that needs the functions, no
compiling error, but runtime error when I try to use the function, such as
$x-as_bin();
this is my code:
my $x = 10;
$c-stash-{mybinary} = $x-as_bin();
Please help me to get this right. Also, I could not install
Bundle::Math
Thank you.
If you're on Debian (Etch) or derivatives, the perl-modules package
contains Math::BigInt. How did you install the library? You could also
check if the installation directory for that module is included in
@INC. Also, I think the module names and packages are
case-sensitive...

Hello all,
Is there a best practice way to maintain a map of URLs used in
a Catalyst application. To clarify, I need to map actions to
URLs outside of Catalyst (CRON jobs, Emailers, etc) and won't
have access to $c-uri_for or the $c-dispatcher.
If you need to do this, your design is broken.
Perhaps, but I ascribe that to it being in transition :)
Step back. Explain what you're trying to achieve.
Automated emails sent out to users need to provide them with a
list of different webapp URLs. These actions are asynchronous
from the webapp itself. I have a number of scripts (a few are
legacy dinosaurs) that need webapp URLs as well.
If I choose to change /cancel to /account/cancel later on, I'd
like to do it in one place. I realize that without parsing the
controllers' actions I can't expect the outside code to get those
URLs. I would also rather not use MyApp.pm in simple scripts
that only need my model logic and a URL, and in some cases I can't.
Explain can't in a form that doesn't make me feel you've just
completely missed the point of achieve and told me what you're
trying (failing) to implement :)
I'd like to routinely send an email to a user telling them to pay
for something, including a link to a page in my webapp allowing
them to do so.
I just use Catalyst::Engine::JobQueue::POE (or in older apps a script
that's the moral equivalent) and uri_for for that.
My hope was to configure the URL mapping in a config file, which
could be accessed by my webapp and outside scripts. Something
like this:
sub cancel : Args(1) : Path($urlmap-{account_cancel}) {
# action
}
This, of course, does not work because attributes do not evaluate
their arguments. Perhaps my solution is to subclass the
Dispatcher to allow for:
sub cancel : Args(1) : FromURLMap('account_cancel') {
# action
}
That wouldn't be too hard. Thoughts?
Yeah, Catalyst already has an implementation for this -
package MyApp::Controller::Foo;
...
sub cancel :Action :Args(1) { ... }
then in myapp.conf
Controller Foo
Action cancel
Path /cancel
/Action
/Controller
You can apply any attribute like that, although setting Args or
similar from the config file might be considered unwise.
Perfect, I had missed that this type of URL to action mapping was
possible with the :Action attribute. I have no interest in placing
Args or other attributes in the config. This should work fine for me.
:Action isn't -required-, you just need at least one
attribute. :Action is the long-standing traditional no-op attribute
(:Private isn't valid with any other attrs) so I tend to add it to
all of them so if I delete the :Args for whatever reason or don't
have one in the first place things don't go batshit on me :)

Re: [Catalyst] sane AJAX strategy

Right, I use AJAX to mean both.
ok ... so does the the controller know that the req is ajax? how? an
added argument like ?ajax=true perhaps ... ?
I look at the request headers.
=cut
sub is_ajax {
my $c = shift;
my $headers = $c-req-headers;
return $headers-header('x-prototype-version')
|| ( ($headers-header('x-requested-with')||'') eq 'XMLHttpRequest' );
}
right. so in this case there is a generic [% IF ajax %] in your
template code that suppresses headers, footers and so on?
Kind of. Something like this -- I capture the tables into
page.just_table and then:
SWITCH page.type || template.type;
CASE 'text'; # render as-is. Page is not html
content;
CASE 'html';
content WRAPPER page/html.html
+ page/layout.html# standard site layout
+ includes/tabs.html # include tabs, if available
+ includes/pager.html;# also page navigation
CASE 'ajax_table'; # just return the content of the table
page.just_table;
END;
For AJAX requests that don't update the entire page content, like an
auto-complete search box, I still use the same controller as for the
non-ajax request but then the controller has a little extra code to
return just the search results not the entire new content -- it's just
one extra line of code in most cases. Not always the most efficient
method (since I end up returning more columns than is really needed for
the ajax update), but so far has not been an problem.
so do you typically use the same controller action, and have a flag to
tell it to act differently?
Yes, kind of. Some things are common enough (like search boxes) so I
have a method for it.
So a controller that shows a list of users (possibly limited by a
search) looks like this:
sub list : Path {
my ($self, $c, $limit ) = @_;
my $options = $self-search_options( $c, $limit );
return if $c-ajax_search( $options, qw/ first_name last_name email / );
$c-paged_list( $options );
}
search_options parses out the parameters from the request -- $option
is basically:
$options-{class}-search( $options-{criteria} )
kind of thing. Then ajax_search() does the query and uses a template
to format for the auto-complete javascript. paged_list() is just a
method to generate a list based on rows and columns and how it should
be sorted.
Not very helpful without seeing all the code, I suppose, but it's just
stuff I use in a bunch of controllers so it's factored out.

[Catalyst] Not getting passed arguments in $c-user methods
Hi,
I'm fairly new with Catalyst, so please forgive me if this is obvious.
I'm using a DBIx::Class Person class for the authentication store.
I've extended this Person class using a custom component. (This is
running on mod_perl 1.29 and Apache 1.3.33 on Debian stable.)
That all works well enough, I can access the class and its methods via
$c-user. However, the methods are not getting any arguments other than
$self.
In a catalyst action I tried this code:
---
$c-log-info( $c-user-return_arg('first') );
my $user_obj
= $c-model('MacWebDB::Person')-find( $c-user-person_id() );
$c-log-info( $user_obj-return_arg('second') );
---
where the return_arg method is added to Person via a component:
---
package UMN::MAC::DBIx::Person;
use base qw( DBIx::Class );
__PACKAGE__-load_components( qw( Person_Component PK::Auto Core ) );
[...]
package DBIx::Class::Person_Component;
use base qw( DBIx::Class );
sub return_arg {
my ($self, $arg) = @_;
return arg: $arg;
}
1;
---
Then in the log, I find this:
[info] arg:
[info] arg: second
So in both calls, I'm getting the correct method, but only the second
version receives any arguments.
I'm using the following plugins:
use Catalyst qw/
-Debug
ConfigLoader
Static::Simple
Email
HTML::Widget
Session
Session::Store::FastMmap
Session::State::Cookie
Authentication
Authentication::Store::DBIC
Authentication::Credential::Password
Authorization::Roles
/
;
Thanks for any suggestions.

Octavian Rasnita wrote: And I think this is what is wanted, because I can't see other needs for having 2 separate sessions on the same computer. There is no need for having two separate sessions if you can guarantee the user will ALWAYS be able to finish one task before starting another. That works beautifully in theory, not so well in real life. Practical case one: database of users for an ISP. A helpdesk operator is going through his tickets, looking up one user at a time, when a phone call comes in. He now either has to deal with the customer without looking them up (practically impossible), or he has to abandon the session where he half completed the processing of the ticket in order to look up the customer. Both alternatives are unappealing. Practical case two: a webshop where items can be customised. (i.e. first you choose a widget, then you specify the color, case design, ram size, two wheels or four, Let us say all of those choices affect the price). As long as your customers go through the shop one widget at a time, everything is fine. But if he goes through two different sessions at a time because he wants to comparison shop, they have a problem. If *all* your state is in the cookie, it is simply impossible for them to do that. There are very good reasons why PART of the session information should be unique to each tab, and PART of it should be common. Deciding which part belongs where requires knowledge of the problem domain, and thinking through of common usage scenarios. Saying Oh, that problem is solved by choosing browser X is completely unacceptable in the real world. In the real world, you can NOT choose which browser all the people using your application will run, nor can you afford to turn away those who run different browsers. ___ List: Catalyst@lists.rawmode.org Listinfo: http://lists.rawmode.org/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.rawmode.org/ Dev site: http://dev.catalyst.perl.org/
