django delete view override delete method

im using the delete view and i want to customize the action of the deletion.

there are some checks i need to do before deleting the object and in case the

checks doesn't pass i want to redirect to the same view and show a matching

massage (just like i can do in the form_valid method with the form.add_error

and return self.form_invalid(form)).

so i have the following delete method:

def delete(self, request, *args, **kwargs):
    if XXXX:
        ### add_error and return a massage ###
    else:
        return super(delete, self).delete(request, *args, **kwargs)

what i need/can do in the "if" to prevent the deletion and explain the user

what the problem is?

thx

To prevent deletion you just have not to call super().delete in the if clause.

For explaining why deletion was not performed you can use django messages (https://docs.djangoproject.com/en/1.8/ref/contrib/messages/)

So I think you can use something like this in your if clause

messages.add_message(request, messages.WARNING, 'Object was not deleted')
return self.render_to_response(self.get_context_data())

And you'll be able to access message text using code from django messages documentation: https://docs.djangoproject.com/en/1.8/ref/contrib/messages/#django.contrib.messages.get_messages
