DjangoRelatedObjectDoesNotExist at /profile/

Viewed 32

I've been through in similar topics for days for a possible solution, however none of them solved my issue which seems pretty simple to me but I stucked on this error right after I created a user: RelatedObjectDoesNotExist at /profile/ Error I'm getting

I know there must be something missing in my singlas.py which does not create the Profile after creation of a User but I'm lost in solutions after tried many. Any help will make my day after long frustration period;

Somehow I sort it out; but I dont know the logic behind of it. I literraly coppied my two function from signals.py file into my models.py file with the releted imports and it's worked :)

There is the final models.py

from django.db import models
from django.contrib.auth.models import User  
from PIL import Image  

from django.db.models.signals import post_save  
from django.dispatch import receiver  


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'  

    def save(self, *args, **kwargs):  
        super().save(*args, **kwargs)  

        img = Image.open(self.image.path)  
        if img.height > 300 or img.width > 300: 
            output_size = (300, 300) 
            img.thumbnail(output_size) 
            img.save(self.image.path)
 

@receiver(post_save, sender=User)  
def create_profile(sender, instance, created, **kwargs):  
    if created:  
        Profile.objects.create(user=instance)

@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
    instance.profile.save()
