RelatedObjectDoesNotExist. User has no profile

Question

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:

Exception Type: RelatedObjectDoesNotExist at /profile/
Exception Value: User has no profile.

forms.py:

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


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

    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']


class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ['username', 'email']


class ProfileUpdateForm(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ['image']

signal.py:

from django.db.models.signals import post_save
from django.contrib.auth.models import User
from django.dispatch import receiver
from .models import Profile


@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()

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 1

the problem is in views.py after def profile you should call the get_or_create method for your Profile model so the view will look like this

@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) 

Answer 2

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.

define all apps in the end of Installed apps.

Installed Applications:
[
 'django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'blog', #use <your_app>.apps.<YourAppConfig (class name)> instead of app name
 'users',
 'crispy_forms',
 'django_cleanup',
]
