Сбой ограничения NOT NULL: users_profile.usertype

0 голосов
/ 06 февраля 2020

Я пытаюсь создать приложение Django, в котором могут регистрироваться пользователи двух разных типов - арендаторы и арендодатели. Я добавил BooleanField в мой models.py, который добавит запись в БД, а в мои forms.py я добавил ChoiceField, где пользователи могут выбирать, кто они.

После нажатия кнопки Регистрация, учетная запись создана, но я получаю IntegrityError at /register.

Я использую Python 3, Django = 3.0.3 и django -crispy-forms = 1.8.1

модели. py 

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

usertypechoices = [(1,'Landlord'),(2,'Tenant')]

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')
    usertype = models.BooleanField(choices=usertypechoices)

    def __str__(self):
        return f'{self.user.username} Profile'

    # Resize images to reduce memory wasted
    def save(self, *args, **kwargs):
        super(Profile, self).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)

forms.py 

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

class UserRegistrationForm(UserCreationForm):
    email = forms.EmailField()
    usertype = forms.ChoiceField(choices=usertypechoices)

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

views.py 

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


def register(request):
    if request.method == 'POST':
        form = UserRegistrationForm(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 = UserRegistrationForm()
    return render(request, 'users/register.html', {'form': form})
