HTTP GET /messages/notification/ 500 [0.16, 127.0.0.1:56012]
Also here is my code:
models.py
class ProfileImage(models.Model):
"""
Profile model
"""
user = models.OneToOneField(
verbose_name=_('User'),
#to=settings.AUTH_USER_MODEL,
to = User,
related_name='profile',
on_delete=models.CASCADE
)
avatar = models.ImageField(upload_to='profile_image')
notifications = models.FloatField(default='0')
views.py
def notifications(request, user_id, *args, **kwargs):
user = User.objects.get(pk=user_id)
user.profile.notifications = user.profile.notifications + 1
user.save()
return JsonResponse(data=user.profile.notifications, safe=False)
urls.py
path('messages/notification/', notifications)
my html for the ajax call
// Add the notification val
$.get('notification/')
someone tell me that is that I dont have users, but when I do have a user, I dont know what is going on

Answer 1

You need to send user_id to the view:
path('messages/notification/(?P<user_id>[a-zA-Z0-9/_\.-]*)', notifications)
and:
$.get('messages/notification/{{ user.pk }}')
Update
You have to know their user id to get their notifications:
$.get('messages/notification/12234')
I assume you have a User model somewhere?
Also, user_id is coming in as a string, so need to int() that:
user = User.objects.get(pk=int(user_id))
Or use:
path('messages/notification/<int:user_id>', notifications)

Answer 2

So for does who saw this later, what I did is to change the
path('messages/notification/', notifications)
To
url(r'^ajax/notification/$', notification),
