How to add a cancel button to DeleteView in django

django, django-class-based-views

Solution

Your approach of overriding the `post` method and checking to see if the cancel button was pressed is ok. You can redirect by returning an `HttpResponseRedirect` instance.

from django.http import HttpResponseRedirect

class AuthorDelete(DeleteView):
    model = Author
    success_url = reverse_lazy('author-list')

    def post(self, request, *args, **kwargs):
        if "cancel" in request.POST:
            url = self.get_success_url()
            return HttpResponseRedirect(url)
        else:
            return super(AuthorDelete, self).post(request, *args, **kwargs)

I've used `get_success_url()` to be generic, its default implementation is to return `self.success_url`.

Problem

What's the best way to add a "cancel" button to a generic class-based view in Django? In the example below, I would like the cancel button to take you to `success_url` without deleting the object. I have tried adding a button `<input type="submit" name="cancel" value="Cancel" />` to the template. I can detect if this button was pressed by overriding the post method of the `AuthorDelete` class, but I can't work out how to redirect from there. Example myapp/views.py: ``` from django.views.generic.edit import DeleteView from django.core.urlresolvers import reverse_lazy from myapp.models import Author class AuthorDelete(DeleteView): model = Author success_url = reverse_lazy('author-list') def post(self, request, *args, **kwargs): if request.POST["cancel"]: return ### return what? Can I redirect from here? else: return super(AuthorDelete, self).post(request, *args, **kwargs) ``` Example myapp/author_confirm_delete.html: ``` <form action="" method="post">{% csrf_token %} <p>Are you sure you want to delete "{{ object }}"?</p> <input type="submit" value="Confirm" /> <input type="submit" name="cancel" value="Cancel" /> </form> ``` (Examples adapted from the docs)
