Re: [Catalyst] Trouble using Catalyst::Controller::FormBuilder
Hi,
this is a Moose thing. It inlines things like the constructor of the
Controller object. But since the controller is only instantiated once
(anyone correct me if I'm wrong) this won't give you a lot of a
speed improvement. Just remove the line and be happy :-)

I think you are looking in the right direction with the this though; try
validating it in your function to ensure it contains what you're expecting
perhaps?
Also, can you verify that jquery is actually getting loaded OK?
ie. In your document, put something like:
$(function() { alert(jquery has loaded!); });
and check to see that you get an alert box when you load the page. If not,
fire up Chrome's developer tools, or Firefox's Firebug, and see they mention

calls of

But in Catalyst::Manual::Tutorial::04_BasicCRUD.pod I read:

This will override the definition for these fields that
Schema::Loader

What's the truth? Repeating calls of this method adds more columns

They are replaced if the name you supply matches a previously setup
column.
So both is true :-)

When they login, this information is stored into their session, and retrieved whenever. agreed. I would store it in the session in the form you want it to be presented, which would save you whatever time it would take to be inflating it. Now the problem begins: I have tables for studies, series and images (and many more), each of them has multiple timestamps (e.g. when the study was created, the series acquired, the image processed, and when everything was created and deleted). So when I access all these times, I would have to convert all of them, e.g. in a template [% study.time.convertTZ(c.user) %] [% series.time.convertTZ(c.user) %] rather than just use (after Catalyst knows about the users timezone, somehow). [% study.time %] [% series.time %] and I must not miss a single value. And things get even more complicated when I filter for times (e.g. show images created in the last 3 hours), or if I want to show only datasets whose deletion date is in the past (could have be deleted in Europe and should also be gone in the US). Hi Christian, I don't quite get the above paragraph. If you search for db entries which have been created in the last 3 hours and you have a column created_on which stores the time of creation incl. time zone (of your server) you won't face any problems because you can simply search for them. The problem occurs only if you store the current time of the user without time zone in the created_on column. To the original question: I'd say that the conversion between time zones belongs in the View. As you are doing it already with [% study.time.convertTZ(c.user) %]. I see that this means you have to type more but neither the controller nor the model should do this conversion. moritz ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/

The problem was fixed by calling utf8::decode on the data prior to sending back via ajax. BUT WHY? I am using the JSON view to render ajax responses, and it sets the charset header correctly to UTF-8. Of course, even when you decode, perl still represents as internal utf8. But why should this be necessary? Thanks! What is the encoding of the web page that issues that ajax request? Does this occur on different browser as well?

Re: [Catalyst] Potential query string pollution vulnerability?
Am 16.06.2009 um 11:11 schrieb Tobias Kremer:
Hi all,
I just experienced a nasty case of query string pollution
vulnerability in one of my Catalyst/DBIC apps. I think that the
circumstances under which this applies are not _that_ rare, so I
figured it'd be best to inform the world.
Imagine the following code in one of your actions:
sub crashme :Local {
my( $self, $c ) = @_;
my $result = [ $c-model( 'Foo' )-search( {
-or = [
name = $c-req-param( 'name' )
],
} ) ];
}
To me, this never looked like a potential security threat because
$c-req-param('name') is correctly inserted/quoted via bind
parameters, right? Well, let's see what happens, if we pollute the
query string a bit:
/crashme?name=Fooname=Bar
This results in the following SQL:
SELECT ... FROM ... me WHERE ( ( name = ? OR Bar IS NULL ) )
Oh oh! :(
'Bar' is used as a column name here because Catalyst::Request::param
returns an Array if the caller desires it (wantarray). Solving this
problem is easy: Either force scalar context, or force array context
and take only the first element.
I'm not sure if it makes sense or is even possible to fix this within
DBIC and/or Catalyst. By the way, I'm using DBIC 0.08107 and Catalyst
5.71.
What do you think?

The tables that break FormFu have relationships defined where the

to true, everything seems to work fine.
Eg.
__PACKAGE__-belongs_to(
gp = 'My::Schema::Result::GP',
{ id = 'gp' },
{ is_foreign_key_constraint = 0 }
);
I didn't write the DB schema so I'm not sure why they indicated
these weren't foreign keys, when they are, but I still don't think
FormFu should barf on them.
What do you think?

Re: [Catalyst] how to reuse Catalyst Schema for non-web purposes?
So it's the model I put the business logic in? That sounds ok, for now. But what about this: * Input from the web has to be validated. May be I use Data::FormValidator, may be FormFu. However, I may have to validate the params I get from the script (eg. data import from ERP systems), too. Do I have to implement the validation again? And maybe normalization/converting, too? Or where would you place these functionality? Extra modules? You are not limited by the number of models. You can write a model which does the form/data validation and which calls the dbic model to insert the data. Just place an extra layer between your controller and your dbic model. * What about business logic that is in not only bound to a specific schema but has an overall logic that fetches data from different tables, adds some somewhere and produces results? How would you implement such a logic? Any examples? I would write an extra model for this or you create a resultset class which can handle that. This very much depends on the data which is needed. * An example for using data and logic outside of the web app would be generating invoices by night. That process would bring out some PDFs which will be printed or sent by mail through another script. Shouldn't a view be involved in this process that builds the PDFs from templates? Is it possible to build this example upon a Catalyst web app? Examples? I use Template::Plugin::Latex to create a TeX document which is then converted to a pdf. But this is totally independent from catalyst. It is a script which is run once a day and generates the invoices. No need to follow the MVC scheme here. If you plan to run those jobs with catalyst I'll suggest you have a look a job queue which can help you with that (e.g. TheSchwartz). moritz ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/

About usage I found only this:

Hi Neo,
Are you running a really old version of Catalyst::Devel?
If you specify the -r option to myapp_server.pl that was generated
with a (oh, 2 years?) very old version of Catalyst::Devel it will
not work right.
This option clobbers your engine and sets the engine to
'HTTP::Restart'. Take a look at your script/myapp_server.pl and
find the section for checking $restart
The proper lines should be:
if ( $restart $ENV{CATALYST_ENGINE} eq 'HTTP' ) {
$ENV{CATALYST_ENGINE} = 'HTTP::Restarter';
}
It used to omit the test for CATALYST_ENGINE, and ... well, that's
not right :)
Otherwise, it should definitely throw an error for an invalid
engine being specified:
$ CATALYST_ENGINE='Yourmom' perl script/myapp_server.pl
Can't locate Catalyst/Engine/Yourmom.pm in @INC
-J
Ha! Thank you very much, this was exactly the problem!
Our startup-scripts indeed seem to be abount two years old. I
remember seeing a warning about old scripts once, but haven't seen
them in a while and thought one of my colleagues fixed it.
If I may ask a following question how to rebuild the scripts?

}
});
};
var form = [% form.render %];

});
/script
I needed to make these changes to get it to display.
Yes that's correct. HTML::FormFu::ExtJS helps you with creating the
form only.
The whole logic is up to you.
There are many ways to display a form. I usually put them in an
Ext.Window.
But you can still render them directly to your html body.

# $c-stash-{message} = 'Hello World!';
$c-stash-{books} = [$c-model('DB::Books')-all]; ### this
doesn't work
$c-forward('MyApp::View::JSON');
}
any pointers into the right syntax/approach here would be greatly
appreciated. I presume i have to write some kind of JSON encoder for
the data coming out of $c-model('DB::Books')-all?
thanks again for your help
Hi,
You can access the raw data through $row-{_column_data}. But this is
not recommended because it doesn't call any inflators.
try
$c-stash-{books} = [map { $_-{_column_data} } $c-
model('DB::Books')-all];

Re: [Catalyst] In search of RESTful CRUD holy grail
Am 04.03.2009 um 13:25 schrieb Zbigniew Lukasiak: This might be a futile mission - but I think I learn something with each recurrence of this discussion. So let's restart it once again. CatalystX::CRUD::REST has a well described RESTful URI structure: # POST /foo- create new record # GET /foo- list all records # PUT /foo/pk - update record # DELETE/foo/pk - delete record # GET /foo/pk - view record # GET /foo/pk/edit_form - edit record form # GET /foo/create_form- create record form I think everyone will agree that this is indeed REST. For some cases there might be a slight problem with that URI schema - if you have a string primary key - and it can have the value of 'create_form' - then you will not know if the client is requesting a view on the object with that id or if he wants the page with the form to create a new object. This leads to new variation: # POST /foo- create new record # GET /foo- list all records # PUT /foo/by_id/pk - update record # DELETE/foo/by_id/pk - delete record # GET /foo/by_id/pk - view record # GET /foo/by_id/pk/edit_form - edit record form # GET /foo/create_form- create record form Of course 'by_id' could be 'instance' or whatever (perhaps the library should let the user to choose that infix part). Now '/foo/by_id/pk/edit_form' needs to make a PUT request to /foo/by_id/pk. To get around the problem with requests outside of the basic 'GET' and 'POST' repertoir we can use Catalyst::Request::REST::ForBrowsers. But it also means that for browser requests in the case of mistakes made in the form the action answering that PUT request to '/foo/by_id/pk' needs to render the form again with error indicators. But for non browser requests in case of similar errors it needs to encode those errors in some other way. This shows that 'edit_form' is only informing us how to *render* (or serialize) the data. In the case of GET requests it informs us that we should render the object data inside of a form and in the case of a PUT request with errors it informs us that we should similarly put the error data into the form. This leads to next variation: # PUT /foo/by_id/pk - update record or return the error encoded for non-browsers # PUT /foo/by_id/pk/edit_form - update record or return the error encoded as HTML form # DELETE/foo/by_id/pk - delete record # GET /foo/by_id/pk - view record (for non-browsers encoded) # GET /foo/by_id/pk/edit_form - view record encoded as an edit form And similarly: # POST /foo - create new record # POST /foo/create_form - create record form # GET /foo - list all records # GET /foo/create_form - create record form i.e. - here we treat 'edit_form' and 'create_form' consistently as a path info parameter informing us about the serialization method. The advantage of this arrangement is also that we don't need to put any address into the 'action' parameter of the form - and let it always submit to itself. In another variation we could move that parameter from path info to real parameters and have uris like: # PUT /foo/by_id/pk- update record or return the error encoded # PUT /foo/by_id/pk?x-view=edit_form - update record or return the error encoded as HTML form # DELETE/foo/by_id/pk- delete record # GET /foo/by_id/pk - view record (encoded) # GET /foo/by_id/pk?x-view=edit_form- view record encoded as an edit form Finally we need serialisation and dispatching to different methods for the same address (/foo/by_id/) based on the method. This is covered by Catalyst::Controller::REST. What I have not yet explored is how to add this new serialisation method (to 'edit_form') to the configuration of a Catalyst::Controller::REST based controller. Hi, here are my thoughts on this: I don't distinguish between edit_form and create_form. If there is a primary key or similar avaiable (either in the path or in $c-req- param) I show the edit form, if there is no such value I show the create form. Furthermore I would not put the form rendering in the same path as the REST interface. I would do something like this: # POST /foo- create new record # GET /foo- list all records # PUT /foo/pk - update record # DELETE /foo/pk - delete record # GET /foo/pk - view record # GET

I would say a form should post / put / delete to the rest api. Within that controller we can easily see if a browser is requesting this url or a web service (see ForBrowser's looks_like_browser()). If it's a browser we can detach to the /form/foo controller. Otherwise we show the errors in the format of the Accept header. I don't like this, however. If your UI is all AJAXy, by all means let it use the REST api directly. But for old-school HTML forms, I'd post to the /form/foo or /form/foo/pk and let that controller either call the REST api internally, or bypass it altogether.

Yeah, that was unclear. I was talking about our own sites

which I suggested script based attacks were by definition
going to be XSS. Malicious ActionScript is still script.
But I hadn't read the POST exploits as described in the

Might be pretty simple in Cat stuff. The crux of the POST
issue seems that the target site's cookies are still safe
from the attacking site's POST. So, off the top of my
head, untested, please modify, correct, refine, put
in wiki, etc.
Form template:
form action=[% c.request.uri() %] method=post
[% USE Digest.SHA1 -%]
input type=hidden value=csrf_check value=[% c.sessionid |
sha1_hex %] /
/form
Controller form validation:
use Digest::SHA1 qw(sha1_hex);
some_error_or_other() unless
$c-user_exists
and
$c-request-body_params-{csrf_check} eq sha1_hex($c-sessionid);
I think this gives you a good protection. But if you have a
XSS problem with your website the attacker could receive the
session cookie via XSS (see the facebook example above).
After that he can set up his form using the checksum.
The best way is to include a random string which has to be stored
somewhere for comparison on the server side.

Re: [Catalyst] Slow template processing on debian lenny
Hi,
I've been using TT for years and enjoy the features it provides. In
one of
my Catalyst applications, I'm processing a template which generates
HTML to
give me a table with counts taken from a hash. I'm using a lot of
nested
FOREACH to generate the table.
On my machine, an ubuntu hardy, it works fast - about 2.5 seconds to
process the template. On a production server using debian lenny, it
used to
take around the same amount of time. But recently, I upgraded it to
libperl
5.10 and updated the different Perl modules including Template and
Catalyst::View::TT. After this upgrade, the same template takes 25
seconds
on average to process. The times I am mentioning are the times taken
on the
server side, as shown by the Catalyst application debug logs.
I tried to work around the problem by bypassing C::V::TT and using the
following code to process the template inside the controller, but to
no avail:
my $tmpl = Template-new({
INCLUDE_PATH = $c-config-{home} . '/root',
RELATIVE = 1
});
my $output = '';
$tmpl-process('index.tt', { %{$c-stash}, c = $c }, \$output);
$c-res-body($output);
Try Template::Alloy instead. It's a fully compatible faster
implementation of TT.
replace
my $tmpl = Template-new({
INCLUDE_PATH = $c-config-{home} . '/root',
RELATIVE = 1
});
with
my $tmpl = Template::Alloy-new({
INCLUDE_PATH = $c-config-{home} . '/root',
RELATIVE = 1
});
and install Template::alloy, of course.

Re: [Catalyst] Pushing data to Catalyst powered web page
Good afternoon all
I am busy with a project where I need to read an RFID tag, get the
data
associated with the tag and then push the data to a web page for a
security person to monitor.
I can successfully read the tag by using LogicAlloy's ALE server. It
then calls my Catalyst application at http://localhost/ale/notifier :
sub notifier : Private {
my ( $self, $c ) = @_;
#$c-stash-{template} = 'notifier.tt2';
$c-stash-{tagdata} = $c-request-params-{tagdata};
open (TagData, 'C:\Eclipse Projects\Asset
Tracker\AssetTracker\lib\AssetTracker\tagdata.txt');
print TagData $c-request-params-{tagdata};
close TagData;
}
As you can see I do not get the associated tag data yet, I am just
trying to display the tag data received from the ALE server.
I can see that the data is coming through correctly by monitoring the
console debug and checking the tagdata.txt file.
The problem that I have is that I have no idea how to push the data
to a
web page instead of pulling.
Hi,
you might want to have a look at http://meteorserver.org/. This server
pushes data to a client via a persistent http connection. To handle
such things with catalyst is not a very good idea. the ALE server will
talk to the meteor server and not the catalyst application.
If you do not need realtime push you could reload a catalyst page
every x seconds.
This page opens the file tagdata.txt and prints its content. Add a
html meta tag to reload the page every x seconds.

How are you generating the JSON? We had a similar circumstance
(although our production server would also exhibit failures under
the
built-in server) because of varying JSON.pm versions.
Make sure you use a JSON module that properly understands
unicode. I
try to use Catalyst::View::JSON wherever possibly, and if it isn't
then JSON::XS::encode_json( $perlref ) works the most reliably.

I use standard JSON module [use JSON;] from cpan,version is 2.07.
code like
below:
my $json = new JSON;
$json-canonical(1);
my $response = $json-encode($var);
But i think the problem is nothing to do with JSON, for some
points like
below:
1. The problem will not occur when I use catalyst's built-in server
2. After JSON module convert a hash to JSON data, I use $c-log-

$c-log-debug(JS Response:\n$jsResponse); # the showed on the

Re: [Catalyst] Dispatching with Chained vs HTTP method
Hi Zbyszek,
do you plan FormFu support? In case the submitted values are not valid
the response is a xml/json/whatever which includes the error messages.
That would be really great :)

just looking for some advice on the best way to do something..
So I wrote a controller class using Chained that basically auto-
converts any
DBIx::Schema (which includes a tiny extra base class itself) into a
REST API..
Well, a simple one anyway - it supports find and search so far, and
foreign
keys in the objects get serialised into hashes of the URIs to fetch
them.
All working nicely so far, but this is all for GET queries.
But the behaviour should be different depending upon whether you
GET /item/1234
or
DELETE /item/1234
etc.
I was thinking something like this: (Abbreviated code below)
sub item_by_id : Chained CaptureArgs(2) {
my ($self, $c, $type, $id) = @_;
$c-stash-{item} = $c-model(DB:$type)-find($id);
}
sub delete : Chained('item_by_id') Args ActionClass('MethodDELETE') {
my ($self, $c) = @_;
$c-stash-{item}-delete;
}
sub modify : Chained('item_by_id') Args ActionClass('MethodPUT') {
my ($self, $c) = @_;
$c-stash-{item}-update($c-request-params);
}
Then the appropriate ActionClasses would check if the $c-req-
method eq 'GET'
or 'DELETE' or whatever.
But I was just wondering if you had other ideas, and if using
ActionClasses
with Chained actions is crackfuelled and going to lead to a world
of misery and
pain.
Cheers!

Re: [Catalyst] Re: CatalystSites.org
Totally depends. I ported an app to Catalyst that previously was
basically one-action-per-controller. It cannot be called anything
less than a lot of work, but it paid of royally. The code is as
DRY as it was before, but it’s now far better structured.
Previously it was blocks of if-elsif chains grouping together
execution steps that are shared by some URIs but not others – now
it’s Chained. A typical controller looks something like this:
sub base : Chained PathPart('doc') CaptureArgs(0) { ... }
sub list : Chained('base') PathPart('') Args(0) { ... }
sub item : Chained('base') PathPart('') CaptureArgs(1) { ... }
sub view : Chained('item') PathPart('') Args(0) { ... }
sub edit : Chained('item') Args(0) { ... }
This gives `/doc` (goes `base` then `list`), `/doc/*` (goes
`base` then `item` then `view`), and `/doc/*/edit` (goes `base`
then `item` then `edit`).
And then you can put stuff shared by all actions in `base`[^1],
and stuff shared by all actions that relate to a single document
(eg. stuffing that document into the stash) all in `item`.
By liberal use of `PathPart('') CaptureArgs(0)` you can force any
URI to step down any number of intermediate steps you require, so
you can use that to group together shared code any way you see
fit:
sub foo : Chained CaptureArgs(0) {}
sub bar : Chained('foo') PathPart('') CaptureArgs(0) {}
sub baz : Chained('bar') PathPart('') CaptureArgs(0) {}
sub qux : Chained('baz') Args(0) {}
This will dispatch `/foo/qux` across the entire foo bar baz qux
chain. Now consider:
...
This is the best example I've seen! It would be great if you could
write this up and put it in the manual or wiki!
I think I finally know how chained works :-)
thanks!

Re: [Catalyst] RIA on Catalyst
Hi Peter, I'm using Catalyst and ExtJS. I use JSON as the default view and pass everything to the stash so it gets to the UI. I'm not using any REST or SOA or anything like that because my app will never communicate with other apps. Are you sure that all the http methods work with xmlhttprequest? Doing a quick google search I found this: http://lists.macosforge.org/pipermail/webkit-unassigned/2006-March/006215.html I can recommend ExtJS. It has very good docs and is pretty straight forward. I'm using HTML::FormFu too. It does all the validation and I wrote a small wrapper which creates ExtJS forms from formfu form objects. Server side validation can be done pretty easy this way. cheers, moritz Am 10.04.2008 um 19:25 schrieb Peter Edwards: I've been thinking about how to implement a Rich Internet Application type interface using WSDL and REST data sources including some from a Catalyst base in an SOA style environment.

Re: [Catalyst] RFC: Catalyst::Plugin::AutoValidate
Hi Markus,
great plugin. But is it really a plugin? I'd prefer to use it as a
controller base class because it is controller specific. This way you
could chose which controllers should use this plugin and let the
others do their work without being disturbed by this plugin (and you
could still use it in the Root controller).
I think the C::Plugin namespace is already poisened enough :)

They can handle all of the connections (with a long KeepAlive) and only talk to the backend FastCGI when a poll request comes through from the AJAX client. If you're really pushing with a constantly connected client, you'll need a FastCGI process per client. The difference is who initiates communication over the channel. If the server can send to the client at any moment, that's true push. Most people get along with a rapidly polling client that says Anything for me? every so often. In general polling is wasteful of bandwidth, while push is wasteful of server-side resources.

[Catalyst] $c-user-some_relationship always retrives user id from the db
Hi, I request all albums of a user by calling $c-user-albums-all; That results in a query which retrieves the user id and then querys the album table with that user id in the where clause. It works, but how can I prevent that first query which retrieves the user id? Can't I store the user id in the session so that the query could use that value instead of receiving it from the database? I looked through the docs but couldn't find anythink.

[Catalyst] add components to files generated by C::Helper::Model::DBIC::Schema
Hi, I need to add some components to some packages created by Catalyst::Helper::Model::DBIC::Schema. I tried adding them under the md5 checksum so updates wont break, but some of them needed to be placed before Core is loaded. I didn't find anything about this in the docs. Any help?

Re: [Catalyst] Catalyst::View::Email broken?
Hi,
could you also implement a way to put the subject in the template?
Something like (TT):
[% subject = My Subject %]
[% BLOCK content %]
Email content
[% END %]
This makes localization possible for the subject,
when can we expect a new version?
Greets,
Moritz

Done.
But thinking about this module brought me to the conclusion, that it
doesn't buy me anything (besides headaches).
Instead I've put a tiny little send_mail method in MyApp's base class,
that calls Email::MIME::Creator and Email::Send.
Less code that can break (and actually does) and more elegant to say
$self-send_mail($email_mime_object);
instead of
$c-stash-{email} = $email_mime_hash;
$c-forward('View::Email');

Thanks for the bug!
I definitely see your point about the simpler send_mail method, and
I think for a lot of cases it probably is easier that way. I really
want to tie into the template rendering process with it, and that
was my main impetus for writing the module in the first place.
Once I can tie into other views to render attachments, I think it
will be worth it (An attachment sourced from a PDF View, for
example). Until then, it's just slow progression that way.
Thanks for the feedback, though. If you are just doing a plugin
cycle, you may want to look at Catalyst::Plugin::Email.

Re: [Catalyst] Catalyst::View::Email broken?
You could run the code which sends the mail within a template which
gets post processed.
There you can access subject and content and attachments if you
like and pass them to the mail function.
the post processed template could check whether subject or content is
avaiable. if so pass it all together to create the mail. Otherwise use
the stashed subject and the template output for the mail.
I'd prefer this way because you have all your localization in one place.

Moritz,
That patch isn't likely to go in, since subject belongs in the
headers which is outside of the rendering cycle or that mime-part.
If you want to do localization of the subject, just do:
$c-stash-{email}-{subject} = $c-localize(Subject Here);
