How to get the currently logged-in user's id?
in models.py:
class Game(models.model):
name = models.CharField(max_length=255)
owner = models.ForeignKey(User, related_name='game_user', verbose_name='Owner')
in views.py:
gta = Game.objects.create(name="gta", owner=?)

First make sure you have SessionMiddleware and AuthenticationMiddleware middlewares added to your MIDDLEWARE_CLASSES setting.
The current user is in request object, you can get it by:
def sample_view(request):
current_user = request.user
print current_user.id
request.user will give you a User object representing the currently logged-in user. If a user isn't currently logged in, request.user will be set to an instance of AnonymousUser. You can tell them apart with the field is_authenticated, like so:
if request.user.is_authenticated:
# Do something for authenticated users.
else:
# Do something for anonymous users.
You can access Current logged in user by using the following code:
request.user.id
I wrote this in an ajax view, but it is a more expansive answer giving the list of currently logged in and logged out users.
The is_authenticated attribute always returns True for my users, which I suppose is expected since it only checks for AnonymousUsers, but that proves useless if you were to say develop a chat app where you need logged in users displayed.
This checks for expired sessions and then figures out which user they belong to based on the decoded _auth_user_id attribute:
def ajax_find_logged_in_users(request, client_url):
"""
Figure out which users are authenticated in the system or not.
Is a logical way to check if a user has an expired session (i.e. they are not logged in)
:param request:
:param client_url:
:return:
"""
# query non-expired sessions
sessions = Session.objects.filter(expire_date__gte=timezone.now())
user_id_list = []
# build list of user ids from query
for session in sessions:
data = session.get_decoded()
# if the user is authenticated
if data.get('_auth_user_id'):
user_id_list.append(data.get('_auth_user_id'))
# gather the logged in people from the list of pks
logged_in_users = CustomUser.objects.filter(id__in=user_id_list)
list_of_logged_in_users = [{user.id: user.get_name()} for user in logged_in_users]
# Query all logged in staff users based on id list
all_staff_users = CustomUser.objects.filter(is_resident=False, is_active=True, is_superuser=False)
logged_out_users = list()
# for some reason exclude() would not work correctly, so I did this the long way.
for user in all_staff_users:
if user not in logged_in_users:
logged_out_users.append(user)
list_of_logged_out_users = [{user.id: user.get_name()} for user in logged_out_users]
# return the ajax response
data = {
'logged_in_users': list_of_logged_in_users,
'logged_out_users': list_of_logged_out_users,
}
print(data)
return HttpResponse(json.dumps(data))
Assuming you are referring to Django's Auth User, in your view:
def game(request):
user = request.user
gta = Game.objects.create(name="gta", owner=user)
This is how I usually get current logged in user and their id in my templates.
<p>Your Username is : {{user|default: Unknown}} </p>
<p>Your User Id is : {{user.id|default: Unknown}} </p>
FOR WITHIN TEMPLATES
This is how I usually get current logged in user and their id in my templates.
<p>Your Username is : {{user}} </p>
<p>Your User Id is : {{user.id}} </p>
