google app engine 405 http DELETE with AngularJS $resource

Question

I am using GAE Python (with the webapp2 framework) and AngularJS.

I am have trouble with routes on GAE. In fact I have an action in Angular $resource that allows to delete an object in my datastore.

Here's my Angular $resource code:

deleteImage :
        {
            method      : 'DELETE',
            isArray     :  false,
            format      : '.json',
            url         : '/api/hairdressers/:hrd_id/images/:ima_id',
            params      :
            {
            }
        },

When I'm calling this method, that calls this url with the DELETE verb :

mysite.com/api/hairdresser/877848/images/5451681

In my backend I have a route like :

webapp2.Route(r'/api/hairdressers/<hrd_id:(\d+)>/images/<ima_id:(\d+)>', handler=HairdresserRestHandler, handler_method='hairdresser_delete_image', name='HairdresserDeleteImageRestHandler', methods=['DELETE']),

This route calls the hairdresser_delete_image method in the HairdresserRestHandler.

But I have a 405 Method Not Allowed Error message when calling this URL.

I also have others routes which begins with /api/hairdressers/ but with others params and verbs. Does anybody know what am I doing wrong?

The problem I am guessing is in your python server code.

You handler for deleting images should look like this, note that I am defining a function called delete not get or anything else, this will allow the method to be executed.

class HairdresserDeleteImageRestHandler(webapp2.RequestHandler):
def delete(self):
    self.response.write('I will delete an image!')

On another side note make sure your urls match, I notice deleteimage in your Route path but not in the url you are calling /api/hairdresser/877848/images/5451681

Thanks you for your answer ! I am actually using the handler_method= attribute which allows to redirect the request to a specific function in my handler ! Effectively I had not the same url in my $resource and python code, I correct it but still have the same issue ...
