I posted a more specific question earlier but I'll ask this more general question, hope this is OK…

How do I debug Catalyst when a GET request to a URL works but a POST request to a URL fails?

I've got debugging on and I can see my URL, or action, or route or whatever we should call it, loading like this:

[debug] Loaded Private actions:

[snip]

| Private            | Class                     | Method
| /user/update       | MyApp::Controller::User   | update

[snip]

[download]

Then I can also see this:

[debug] Loaded Chained actions:

[snip]

| Path Spec            | Private                  
| /user/*/update       | -> /user/chain (1)
|                      | => /user/update (0)  

[snip]

[download]

Which makes sense, because the URL is myapp.com/user/<a given user's id>/update

But I still have my problem which is that when I do a GET to that URL, everything works. But when I do a POST to that URL, I get an error, actually a 404.

Inside the update method in the Controller, I have something like this:


if($c->req->method eq 'POST'){
    ### update a database
}

But the code appears to be failing before that ever runs, as soon as the POST request is made.

How do I debug this? In another type of application there would be a routing table specifying that a given URL accepts GETs or POSTs or both. But that's not how Catalyst works? How can I verify that a POST to that URL, and implicitly to that Controller and Action, is even allowed? And/or how can I debug what happens specifically when a POST is made and Catalyst throws an error?

More detail: the debug log shows just this:

.---------------------------------------------------------------------
+-------------------------------+-----------.
| Action                                                              
+                               | Time      |
+---------------------------------------------------------------------
+-------------------------------+-----------+
| user/<my user name>/update - start                                  
+                               | 0.024544s |
|  /auto                                                              
+                               | 0.002635s |
|   -> /error_template                                                
+                               | 0.000193s |
|  /end                                                               
+                               | 0.020821s |

so it performed the right Action, then 'auto' took over and it failed at that point?
