 You (and the page) are completely correct, and I missed the relevant line, 
reading through, a half dozen times in a row. Apologies.

Re: Custom password validation

[Helton Alves]

hey man, how are you ?

I don't know if I understand very well, but you can try make a custom user
and in forms file you can do the validation that you need. :D

if that's right, you can follow this example:
http://www.lasolution.be/blog/creating-custom-user-model-django-16-part-1.html

I hope to have helped you!

I've tried a few different things. First I did this:

class UserAdmin(UserAdmin):
form = MySetPasswordForm

# Re-register UserAdmin
admin.site.unregister(User)
admin.site.register(User, UserAdmin)

And I got this error:

: (admin.E016)
The value of 'form' must inherit from 'BaseModelForm'.

So then I changed MySetPasswordForm to inherit from BaseModelForm and
then I got this error:

__init__() missing 1 required positional argument: 'user'

So then I added the user param so now MySetPasswordForm looked like this:

class MySetPasswordForm(BaseModelForm):
def __init__(self, user, *args, **kwargs):
super(MySetPasswordForm, self).__init__(user, *args, **kwargs)
self.fields['password1'].validators.append(validate_password_strength)

But I still got the same error as before.

I can't believe it's this hard to add a password validator. It must be
a very common need, so clearly I must be missing something simple. Can
anyone please provide some assistance here.

If you are talking about part 3 of the tutorial then it in fact contains an
import of Http404 and it's intrdroduced together with the first piece of
code that uses it.

It's right in the views.py snippet located under the "Raising a 404 error"
section title:
https://docs.djangoproject.com/en/1.8/intro/tutorial03/#raising-a-404-error

Tutorial missing import: Http404

[John Matthew Ian Davis]

obviously one needs to change:

from django.http import HttpResponse, 

to

from django.http import HttpResponse, Http404

but that's a speed-bump that should not be in the tutorial.
