I have a form like this
What is the best way to validate for an already existing User when
using the django.contrib.auth.models.User and the new forms
authentication system?
Overiding Form.clean(), and adding some uniqueness validation code
works, but binds the form to the DB. There's not much way around
that, I'm guessing. But is there a better approach?
Details to question below---------------------->
class NewAccountForm(forms.Form):
username = forms.EmailField()
password = forms.CharField(widget=forms.PasswordInput)
I have it all working fine from a view like this
from django.contrib.auth.models import User
import logging as log
def create_account(request):
if request.method == 'GET':
form = NewAccountForm()
elif request.method == 'POST':
form = NewAccountForm(request.POST)
if form.is_valid():
data = form.cleaned_data
log.debug("\n".join(["%s=%s" % (k,v) for k,v in data.items()]))
# Create the account
user = User(username=data['username'],
email=data['username'], password=data['password'])
user.save()
return render_to_response('registration/login.html', {},
context_instance=RequestContext(request) )
# Either initial GET or Validation errors - return to account page
return render_to_response('registration/createaccount.html',
{'form': form }, context_instance=RequestContext(request) )
When I try to create a user that already exists (username exists in
the DB), I get this error
IntegrityError at /accounts/createaccount/
(1062, "Duplicate entry '[EMAIL PROTECTED]' for key 2")
