Hi guys,

first of all, I'm new to Django and this group.

I've just created my first Django login form by extending AuthenticationForm and overriding confirm_login_allowed method to do some extra checks and raise proper exceptions. I've done that based on an example from the Django 1.9 documentation (https://docs.djangoproject.com/en/1.9/topics/auth/default/#module-django.contrib.auth.forms):

class PickyAuthenticationForm(AuthenticationForm):      def confirm_login_allowed(self, user):          if not user.is_active:              raise forms.ValidationError(                  _("This account is inactive."),                  code='inactive',              )  

...

Of course I imported the forms (it would be nice if I didn't have to figure out which forms should I import ...): 

from django import forms

This, however, issues a problem: "... confirm_login_allowed _("This account is inactive."), NameError: global name '_' is not defined".

So, despite what the doc says, I tweaked the code a bit to this, and it works:

class PickyAuthenticationForm(AuthenticationForm):      def confirm_login_allowed(self, user):          if not user.is_active:              raise forms.ValidationError("This account is inactive.", code='inactive',)  

...

I still don't understand why the previous one code didn't work. Is it a mistake in the documentation? I doubt it, and what I think instead is that I imported wrong forms. Instead of:

from django import forms

I should do:

from django.<something different here> import forms

and maybe then the syntax ValidationError would be as in the docs.
