Description

Before rendering template code is supposed to remove email field error on unique validation
"Foo with this Email address already exists."

Code works on previous version of Django 1.8.4
Django 1.9 displays error in template

Model:

class  Foo(models.Model):
     email = models.EmailAddress(unique = True)

View:

from django.views.generic import CreateView

Class BarCreateView(CreateView):
     
       def form_invalid(self, form):
               if form.has_error('email', 'unique'):
                      form.errors.pop('email', None)
               return super(BarCreateView, self).form_invalid(form)

Template:

        <form id="login_form" method="post" action="">
            {% csrf_token %}
            {{form}}
            <input type="submit" value="Submit" />
        </form>

I believe this is a duplicate of #25548, which will be fixed in the upcoming 1.9.1 release.

As a work around until 1.9.1 is released, you can replace the super call

return super(BarCreateView, self).form_invalid(form)

with it's implementation (it's only one line long)

return self.render_to_response(self.get_context_data(form=form))
