I've created a newforms custom form in which I'm trying to update a
user's email while making sure no other user currently has the new
email address. Ignoring the fact that I could use the User generated
forms, I was wondering if anyone could hint on the best way to pass a
variable to a custom forms class.
For some unknown reason the EditUserForm class doesn't see the user
variable.
The error I'm getting is: "global name 'user' is not defined" from the
EditUserForm class.
I know for certain that request.user is valid when I make the call.
I'm pretty sure I don't understand how DeclarativeFieldsMetaclass
works and I think this is where I'm having problems.
Anyone care to enlighten me?
Call from view.py:
data = {'email': request.user.email,}
form = EditUserForm(request.user, data)
Forms Class:
class EditUserForm(forms.Form):
email = forms.EmailField()
def __init__(self, user, *args, **kwargs):
self.user = user
super(EditUserForm, self).__init__(*args, **kwargs)
def clean_email(self):
if user.email is not self.clean_data["email"]:
email_exists = True
try:email =
User.objects.get(email__exact=self.clean_data["email"])
except:email_exists = False
if(email_exists):raise ValidationError(u"E-mail already in
use by another user.")
return self.clean_data["email"]
