filters defined in :before_filter does not seem to get fired when ajax requests are made to the methods in the :before_filter

hi, guys

My rails 3 app is working fine except for resource deletion which uses ajax. The resource is "part".

When the user clicks on the "delete part" link, a confirmation pop up box will appear. Upon clicked on "ok", an ajax request is fired to the 'delete' method in my controller.

In the "parts" controller, I have a before_filter which points to a method which checks if the current user has authorisation to delete the given part entry.

This method works fine for my other methods specified in the before_filter but doesn't for the deletion method.

------------------ extract from: app/view/parts/index.html.erb (start)

I've done some extra checks and observed that with Javascript turned off on my web browsers (chrome and firefox), the destroy method does not get called when I click on it.

in app/views/parts/index.html.erb, i observed that I was using ":method => delete" to generate the deletion link. I have changed it to use 'data-method'=> :delete but it still does not work :frowning:

                                link_to 'Delete',                                         part_path(part.id),                                        :method => :delete,                                         'data-confirm' => 'Are you sure?',                                         'data-remote' => 'true',                                         'class' => 'delete_part'

                                 to

                                link_to 'Delete',                                         part_path(part.id),                                        'data-method' => :delete,                                         'data-confirm' => 'Are you sure?',                                         'data-remote' => 'true',                                         'class' => 'delete_part'

My bad... I put "delete" in the :before_filter's list of methods when the method name is "destroy".

Silly gotcha.

Sorry gents. Hope someone facing roughly the same issue would benefit from this little lesson I learnt.

Cheers :slight_smile:
