[Answered ]-WIth django, can you do something similiar to user = User.new(params[:user]) during a form post?

Look at the model form documentation. Basically, the code would look like:

f = UserForm(request.POST or None)
user = f.save()

If you are talking about Django’s built-in auth app, then keep in mind that there are a few considerations when creating users, such as passwords, unique usernames, etc
