django.db.utils.IntegrityError UNIQUE constraint failed
sqlite3.IntegrityError: UNIQUE constraint failed: new__users_profile.user_id
The above exception was the direct cause of the following exception:
new__users_profile.user_id
Error occurs when I'm trying to register new user, login to an existing user and when I am trying to migrate. I've tried to delete all migrations and migrate once again but it didn't help

I think you need primary_key=True,
class Profile(models.Model):
user = models.OneToOneField(User, primary_key=True, on_delete=models.CASCADE, null=True)
In class profile, add primary_key=True and remove null=True
user = models.OneToOneField(User,primary_key=True, on_delete=models.CASCADE)
I hope it will work!

So In my Django Admin I have a User section (that comes default) and I made a profile section in my forms.py file. I want to add an option when you click in the profile page to redirect to and 'edit' profile page where a user can change their user/profile info including their picture. I'm still pretty knew to Django so I don't know where I need to begin. I have snippets of my code from different parts of my Django app to show because currently I don't know where to start.

The console I cant understand where the issue is located to change to add the label onto the register area any help is fully thank have a good afternoon :)
In your forms, you specified a field for Modal = User, but your Class called Customer. When you say modal = User Django tries to use own User Modal which does not have dateofbirth field.
Im still learning Django and I am stuck at user registration / profile creation.
My goal
So, the purpose of this is to save the new user and at the same time save the profile of the new user with de data from the form. I use 2 forms u_form and p_form.
What I have done so far:
Created model Profile with OneToOneField to User
Created 2 forms for User (u_form) and Profile (p_form)
Created signals.py to create new Profile when new User is created
In the view I have create function with u_form.save()
Problem
This works, but the new Profile is completely empty.. When I put p_form.save() in my view it gives me this error:
NOT NULL constraint failed

If you want Profile fields to be empty initially just add blank=True in every model fields except for user .
voorletter = models.CharField(max_length=10, blank=True)
.....
.....
.....
telefoonnummer = models.CharField(max_length=25, blank=True)
Then run makemigrations and migrate command to successfully make the changes in the database.
it will solve NOT NULL constraint failed error
I am currently developing a blogging webapp and I tried to extend my Django User Framework With a One To One Field, everything is working fine, but when I'm trying to register a new user, it's throwing a NameError. It is also worth noting that the user is being created and stored(I checked it from the admin page). It is saying that this statement profile.user = user in my views.py is creating the problem. Can anyone please help me with this?

The error its showing is from here = from .forms import UserRegisterForm, UserUpdateForm, ProfileUpdateForm
Please have a look what i am doing wrong..
Your forms.py only has a UserRegisterForm. The error complains about the fact that it can not import the UserUpdateForm (and likely if you remove that, it will complain about the ProfileUpdateForm, since that is not defined either). You can fix the problem with the UserUpdateForm by importing it from the django.contrib.auth.forms module, and re-export it. For ProfileUpdateForm, you will need to implement additional forms:
# register/forms.py
from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm, UserUpdateForm
class UserRegisterForm(UserCreationForm):
email = forms.EmailField()
class Meta:
model = User
fields = ['username', 'email']
class ProfileUpdateForm(forms.ModelForm):
class Meta:
model = Profile
exclude = ['user']
