Extend ResetPasswordTokenGenerator to handle arbitraty tokens

[cgenie@…]

The django.contrib.auth.tokens.ResetPasswordTokenGenerator is a useful class, but suitable only for doing one thing. It would be nice to extend it to support generating tokens for other events, like for example customer creation.
Here's the diff on tokens.py:

6c6
< class PasswordResetTokenGenerator(object):
---
> class AbstractTokenGenerator(object):
54c54
<         key_salt = "django.contrib.auth.tokens.PasswordResetTokenGenerator"
---
>         key_salt = '%s.%s' % (self.__class__.__module__, self.__class__.__name__)
69a70,73
> 
> 
> class PasswordResetTokenGenerator(AbstractTokenGenerator):
>     pass

The ResetPasswordToken returns the same value for old and new version of code.

Thanks for the report! I don't think the proposed patch makes sense; the specific user data that is hashed in _make_token_with_timestamp is sensible for the password-reset (as outlined in the comment) but not necessarily for some other use; just changing the key salt doesn't magically make this a one-size-fits-all token generator. If you want to reuse some of this code, you can subclass and override the _make_token_with_timestamp method, and you probably should be doing that anyway.
