RelatedObjectDoesNotExist. User has no profile

I’ve read some other answers for this (almost) question but they didn’t help. I have the following 2 files mixed for user and profile apps(?). In other answers they said this happens if you don’t use >objects.get_or_create or not making signals.py file you’ll get this error but I’ve gone through both of those ways and no results. This is the traceback I get:

forms.py:

from django import forms

from django.contrib.auth.forms import UserCreationForm
from .models import Profile


class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()

    class Meta:

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()

models.py for profile model:

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


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):
        super().save()

        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)

and this is the views.py file:

from django.shortcuts import render, redirect
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from .forms import UserRegisterForm, ProfileUpdateForm, UserUpdateForm


def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            messages.success(
                request, f'Your account has been created! You are now able to log in')
            return redirect('login')
    else:
        form = UserRegisterForm()
    context = {
        'form': form
    }
    return render(request, 'users/register.html', context)


@login_required
def profile(request):
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(
            request.POST, request.FILES, instance=request.user.profile)
        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, f'Your account has been updated!')
            return redirect('profile')
    else:

        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.profile)
    context = {
        'u_form': u_form,
        'p_form': p_form
    }
    return render(request, 'users/profile.html', context)

Thanks for reading this :).

P.S. As I see in admin page, no profiles are made after registration (neither from site nor admin page).

Answer

Good to see someone who’s practicing Django with Corey’s tutorial! It took me few days to catch what went wrong. Here’s how I did it.

Your views.py looks like this:

@login_required()
def profile(request):
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST,
                                   request.FILES,
                                   instance=request.user.profile)

Add one in views.py so that it looks like below

@login_required()
def profile(request):
    Profile.objects.get_or_create(user=request.user)
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST,
                                   request.FILES,
                                   instance=request.user.profile)

If you happen to face same issue somehow, create a new account and go to profile page and see if it throws any error.
