找出Django当前登录的用户

Question

I have created a list of 5 users. How do I find out which user has logged in currently? Also please mention, if there is any way to find out if the super-user has logged in?

My requirement is, I want to restrict the access of certain pages in the templates only to the superuser.

Answer 1

Current user is in request object:

def my_view(request):
    current_user = request.user

It's django.contrib.auth.models.User class and it has some fields, eg

• is_staff - Boolean. Designates whether this user can access the admin site;
• is_superuser - Boolean. Designates that this user has all permissions without explicitly assigning them.

http://docs.djangoproject.com/en/1.1/topics/auth/#django.contrib.auth.models.User

So to test whether current user is superuser you can:

if user.is_active and user.is_superuser:
    ...

You can use it in template or pass this to template as variable via context.

Answer 2

听起来你应该使用内置的权限系统 。

Answer 3

Check out the user_passes_test decorator for your views. Django snippets has a related decorator:

These decorators are based on user_passes_test and permission_required, but when a user is logged in and fails the test, it will render a 403 error instead of redirecting to login - only anonymous users will be asked to login.
