Use signal function to create Profile object upon creation of User object - django

Question

I am a following a tutorial on Django and have the following models.py
from django.db import models
from django.contrib.auth.models import User
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
image = models.ImageField(default = 'default.jpg', upload_to = 'profile_pics')
def __str__(self):
return f"{self.user.username} Profile"
I use the register view to create a User object:
def register(request):
if request.method == 'POST': # if form was submitted w data
form = UserRegisterForm(request.POST) #instantiate form w post data
if form.is_valid():
form.save() #save user to db
username = form.cleaned_data.get('username') #get this to print out success message
messages.success(request, f"Your account has been created. You are now able to log in.") #Formatted string literal for f-string
return redirect('login')
else:
form = UserRegisterForm()
return render(request, 'users/register.html', {'form':form})
Upon creation of a User object I am trying to use signals to create a Profile object. I have created a signals.py file in my app directory:
from django.db.models.signals import post_save
from django.contrib.auth.models import User
from django.dispatch import receiver
from .models import Profile
#Run this function every time a User is created
#receiver(post_save, sender = User)
def create_profile(sender, instance, created, **kwargs):
if created: #if User was created
Profile.objects.create(user = instance)
#receiver(post_save, sender = User)
def save_profile(sender, instance, **kwargs):
instance.profile.save()
and have imported the signals within the ready method of apps.py:
from django.apps import AppConfig
class UsersConfig(AppConfig):
name = 'users'
# To make signals work you have to import your signals
# inside the ready method of our apps.py module
def ready(self):
import users.signals
However, upon the creation of a new User there is still no associated Profile object. Any idea why this is not working?

Answer 1

UsersConfig.ready() never runs and thus your signals are not seen by Django
Solutions
Add users.apps.UsersConfig to your INSTALLED_APPS
OR
Add default_app_config = 'users.apps.UsersConfig' in your __init__.py
OR
Just add your signals directly in your models.py
Checkout: https://docs.djangoproject.com/en/2.2/ref/applications/

Answer 2

Based on the information, I guess you have not defined default_app_config in the __init__.py file of the app.
Open the __init__.py which would be an empty file.
In that, add a line which specifies the value of default_app_config which equals to the path of UsersConfig class which you have defined in apps.py.
It should be following:
default_app_config = 'users.apps.UsersConfig'
Add this line and it should work.
