You should tell us what you want to achieve.

"I want to pass an action to detach()" is not a proper problem description.


The documentation is pretty clear on what is expected.
https://metacpan.org/pod/Catalyst#c-detach-action-arguments

$c->detach( $action [, \@arguments ] )
$c->detach( $class, $method, [, \@arguments ] )
$c->detach()

Have you checked the Catalyst Tutorial. It should provide examples for detach()
There is also the test suite which you can grep for detach.

I'm having a problem with Catalyst randomly deciding when it is OK to have a controller and a model called the same, as I have in the same root auto subroutine ,

$c->detach('splashscreen','index').

Where I have both a controller called 'SplashScreen' and a model called 'SplashScreen', and the detach works fine.

However, for another controller / model pair called 'ComplianceUpdates',

This doesn't work

$c->detach('complianceupdates','index').

and errors with...

Couldn't detach to command "complianceupdates": Invalid action or component.
So If I am to use

$c->detach($action);

How do I create a Catalyst::Action object.
Exactly like I just told you on IRC: $c->detach($c->controller('ComplianceUpdate')->action_for('index'));

What attributes am I meant to be setting in the object before I pass it in, and where are the docs for this as I can't find them.

All help is appreciated.

No the documentation isn't clear, if I could understand it I wouldn’t be asking this question.

What is $action ? And yes I've looked at the manual.

Chapter 3 when you search for 'detach' states..

NOTE: If you use the default template technique, you will not be able to use either the $c->forward or the $c->detach mechanisms (these are discussed in Chapter 2 and Chapter 9 of the Tutorial).

So I go back to chapter 2 and search for detach and get zero results the same when I search chapter 9?

Not sure why you seem to think the tutorial is clear, when I seem to be going round in circles?

Thanks Alexander,

I must have missed this : $c->detach($c->controller('ComplianceUpdate')->action_for('index'));

It's working as desired, much appreciated.

I'm sorry you couldn't understand from the documentation. I'll try and explain
a little more here:

# lib/MyApp/Controller/A.pm
package MyApp::Controller::A;
...

sub my_action_1 :Local {
my ($self, $c) = @_;
$c->res->body('in action 1');
}

sub my_action_2 :Local {
my ($self, $c) = @_;
$c->detach('my_action_1');
}

# lib/MyApp/Controller/B.pm
package MyApp::Controller::A;
...

sub other_action :Local {
my ($self, $c) = @_;
$c->detach('/a/my_action_1');
# or
$c->detach('MyApp::Controller::A', 'my_action_1');
}

Is it clearer now?

Cheers!

Hi Andre,

That is clearer, and Alexander provided me with a working solution, but it doesn't make sense with your example.

$action is an action object isn't it?

So Alexander's example has :-

$c->detach($c->controller('ComplianceUpdate')->action_for('index'));

So I assume

$c->controller('ComplianceUpdate')->action_for('index');

is returning an action object that is passed to detach.

However, your example just has a string path '/a/my_action_1' , how is that an action object?

Are you saying detach (for the single argument signature) takes a URL path and that $action is just a string scalar with a URL path in it and not an action object reference as I got the impression?

Or are there two single argument signatures to detach() one takes an Action object and one takes a URL path string?

Because I did a Data::Dumper of

die Dumper($c->controller('ComplianceUpdate')->action_for('index')) and I got an object!

"$VAR1 = bless( {
'namespace' => 'complianceupdates',
'name' => 'index',
'class' => 'HLP_Members::Controller::ComplianceUpdates',
'attributes' => {
'Path' => [
'complianceupdates'
],
'Args' => [
'0'
]
},
'reverse' => 'complianceupdates/index',
'code' => sub { "DUMMY" }
}, 'Catalyst::Action' );"


Having just tested with : -

$c->detach('/complianceupdates/index');

is working.

So the question now is which is better...

$c->controller('ComplianceUpdate')->action_for('index');

or

$c->detach('/complianceupdates/index');

Pass a string or a pass an object?

Thanks,

Craig.

It's not :) Catalyst magically converts that for you.

See this:

https://metacpan.org/source/JJNAPIORK/Catalyst-Runtime-5.90051/lib/Catalyst/Dispatcher.pm#L148

It either gets an action object, or it translates the path to an object for
you.

I like the string option better. It's cleaner to read. But you should be fine
with both.

Awesome, thanks for demystifying this for me!

# go to a string path ("/foo/bar/gorch")
# or action object
if (blessed($command) && $command->isa('Catalyst::Action')) {
$action = $command;
}
else {
$action = $self->_invoke_as_path( $c, "$command", \@args );
}

I'm still at a loss why when I was using the wrong syntax, it was working for SplashScreen, but the same syntax for ComplianceUpdates wasn't!

And I still can't find where in the docs/tutorial any of this is explained? (a section and page number would be helpful!)

Regards,

Craig.

Below is a piece of text I created for the Catalyst documentation a long
time ago (perldoc Catalyst).
It tries to makes the things a little bit clearer for using uri_for_action()
method, but it is the same in any case an action path is used.
The idea is that even though the action path looks like a URL, it is not an
URL. It is not the URL that calls that action.

""
Note that although the path looks like a URI that dispatches to the
wanted action, it is not a URI, but an internal path to that action.

For example, if the action looks like:

package MyApp::Controller::Users;

sub lst : Path('the-list') {}

You can use:

$c->uri_for_action('/users/lst')

and it will create the URI /users/the-list.

Being pedantic here, but it doesn't accept a URL path; it
accepts an action path. Often they are the same, but they don't
need to be.

# in Root Controller
sub my_list :Path('list') { ... }

You would pass /my_list to detach, but the URL for that action
would be /list.

Hi Charlie,

So it is a URI for a method name in the controller class object you wish to execute.

So rather than matching it as a Path URL, it matches it a as a 'ControllerClass/Method'

So for the URL path in my case would be '/complianceupdates/' , but for detach it is '/complianceupdates/index'

As index is the name of the method that handles the '/' path.

Got it! Many thanks,

Craig.

Or using an action path:

$c->detach( $c->dispatcher->get_action_by_path('/complianceupdate/index') );

It’s a mouthful so if you need it lots, stick a method in your
application class à la

sub path_action {
my $c = shift;
$c->dispatcher->get_action_by_path( @_ );
}

so you can then say

$c->detach( $c->path_action('/complianceupdate/index') );

The advantage or all this is that you change change your url layout without touching the code at all.
