Re: Expire Password Reset Link

Why give out more than one link? Why not use get_or_create to make link or 
use existing link for that user?

Re: How to

Take a look at django permissions/groups models where you can make groups 
and put these models in each group. After that you add the users to the 
group so they can only edit models in that group

Re: no migrations to apply after deleting a field in models

[Nelson Varela]

Don't delete the 0001_initial file!
That is your first state. Just delete the field from you model and do 
makemigrations again.. You wil get a 0002_ file which deletes the field.

Re: Set user permission via python

[Nelson Varela]

Glad you've found the solution. 
One thing I wanted to advice you is to use the get_or_create method on User.
For more detail check the django documentation.
So:
u, created = User.objects.get_or_create(username="user_name", defaults={
email='user...@example.com', password='blah'})

Use the .review you've defined as related name. The _set is when you don't

Re: While registering the user with django form, it gives "UNIQUE constraint failed: auth_user.username" error

[Nelson Varela]

You do not have to save the user 2 times in your form:

user = user_form.save()
user.save()

Maybe this is also the problem...

Login in all pages

[Nelson Varela]

Take a look at middleware.

You can create a middleware which runs for every request. In 'process_request' 
you can check if the user is authenticated. If not... show or redirect to the 
login view.

The advantage is that you don't have to worry about placing decorators above 
your views.

settings.MEDIA_ROOT, 'show_indexes': False}), )

Help a newb with authentication and registration

[Nelson Varela]

Hi,

I don't know what allauth does but you can check the django docs about custom 
auth and user model:

https://docs.djangoproject.com/en/1.7/topics/auth/customizing/

Maybe not what you are looking for but it's a good documentation whichs can 
help you understand more about this topic.
