Excluding password when extending UserCreationForm

Question

I want to make a view where the user can change the attributes for his User object: first_name, last_name and email address. Django has a built in UserCreationForm for creating users. I already have an extended version that also includes email, first_name and last_name. Now I am trying to extend that one to not include the password and username.

from django.contrib.auth.forms import UserCreationForm
class ExtendedUserCreationForm(UserCreationForm):
    class Meta:
        model = User
        fields = ('username', 'password1', 'password2', 
                  'email', "first_name", 'last_name' )

class UserEditForm(ExtendedUserCreationForm):
    class Meta:
        model = User
        exclude = ('username', 'password1', 'password2')

The UserEditForm I am looking for will of course not be able to create new instances, but it will only be used to edit existing instances:

form = UserEditForm(instance=request.user)

However, the username field and password fields are still shown. How can I exclude these?

Answer 1

You can just remove the password2 field in the init of the form like so:

class MyUserCreationForm(UserCreationForm):

    def __init__(self, *args, **kargs):
        super(MyUserCreationForm, self).__init__(*args, **kargs)
        del self.fields['password2']
