Provided that you have enabled the authentication middleware , you don't need to do any of this. The fact that the username shows up in your template indicates that you have enabled it. Each view has access to a request.user that is an instance of a User model. So the following is very much redundant

user = User.objects.get(username=request.user.username)

Because you already have request.user.username !! if you wanted to find the user's email, you do request.user.email Or just do

user = request.user 

and use the newly created variable (eg user.username)

Reference: https://docs.djangoproject.com/en/1.10/ref/request-response/#django.http.HttpRequest.user

From the AuthenticationMiddleware: An instance of AUTH_USER_MODEL representing the currently logged-in user. If the user isn't currently logged in, user will be set to an instance of AnonymousUser. You can tell them apart with is_authenticated, like so:
