python - django: User Registration with error: no such table: auth_user

Question

I try to use Django's default Auth to handle register and login. And I think the procedure is pretty standard, but mine is with sth wrong.

my setting.py:

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'books',
)

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

AUTH_USER_MODEL = 'books.User'

my books.models.py:

class User(AbstractUser):
    account_balance = models.DecimalField(max_digits=5, decimal_places=2, default=0)

my views.py:

from django.contrib.auth.forms import UserCreationForm

def register(request):
    if request.method == 'POST':
        form = UserCreationForm(request.POST)
        if form.is_valid():
            new_user = form.save()
            return HttpResponseRedirect("/accounts/profile/")
    else:
        form = UserCreationForm()
    return render(request, "registration/register.html", {'form': form,})

my urls.py

urlpatterns = patterns('',
    (r'^accounts/login/$', login),
    (r'^accounts/logout/$', logout),
    (r'^accounts/profile/$', profile),
    (r'^accounts/register/$', register),
)

Even I tried delete the db.sqlite3 and re python manage.py syncdb, there's still this error message:

OperationalError at /accounts/register/
no such table: auth_user
Request Method: POST
Request URL:    http://127.0.0.1:8000/accounts/register/
Django Version: 1.7b4
Exception Type: OperationalError
Exception Value:    
no such table: auth_user

Can someone explain and tell me what I should do?

Answer 1

Update

You are probably getting this error because you are using UserCreationForm modelform, in which in META it contains User(django.contrib.auth.models > User) as model.

class Meta:
    model = User
    fields = ("username",)

And here you are using your own custom auth model, so tables related to User has not been created. So here you have to use your own custom modelform. where in Meta class, model should be your User(books.User) model

Answer 2

./manage.py migrate

If you've just enabled all the middlewares etc this will run each migration and add the missing tables.

Answer 3

Only thing you need to do is :

python manage.py migrate

and after that:

python manage.py createsuperuser

after that you can select username and password.

here is the sample output:

Username (leave blank to use 'hp'): admin
Email address: [email protected]
Password:
Password (again):
Superuser created successfully.

Answer 4

This will work for django version <1.7:

Initialize the tables with the command

manage.py syncdb

This allows you to nominate a "super user" as well as initializing any tables.

Answer 5

it is need to make migration before create superuser.

python manage.py makemigrations
python manage.py migrate

python manage.py createsuperuser
Username : admin
Password : 12345678

python manage.py runserver

Answer 6

Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions. try running

python manage.py migrate

then run

python manage.py createsuperuser

Answer 7

If using a custom auth model, in your UserCreationForm subclass, you'll have to override both the metaclass and clean_username method as it references a hardcoded User class (the latter just until django 1.8).

class Meta(UserCreationForm.Meta):
        model = get_user_model()

    def clean_username(self):
        username = self.cleaned_data['username']

        try:
            self.Meta.model.objects.get(username=username)
        except self.Meta.model.DoesNotExist:
            return username

        raise forms.ValidationError(
            self.error_messages['duplicate_username'],
            code='duplicate_username',
        )

Answer 8

Before creating a custom user model, a first migration must be performed. Then install the application of your user model and add the AUTH_USER_MODEL.

As well:

class UserForm(UserCreationForm):

    class Meta:
        model = User
        fields = ("username",)

and

python manage.py migrate auth
python manage.py migrate

Answer 9

Just perform migrations before registering the user.

Answer 10

I have also faced the same problem "no such table: auth_user" when I was trying to deploy one of my Django website in a virtual environment.

Here is my solution which worked in my case:

In your settings.py file where you defined your database setting like this:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',

        'NAME': os.path.join(os.getcwd(), 'db.sqlite3'),
     }
 }  

just locate your db.sqlite3 database or any other database that you are using and write down a full path of your database , so the database setting will now look something like this ;

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': '/home/django/django_project/db.sqlite3',
    }
}  

I hope that your problem will resolve now.

Answer 11

python manage.py makemigrations then → python manage.py migrate fixes it.

Assuming Apps defined/installed in settings.py exist in the project directory.

Answer 12

Please check how many python instances are running in background like in windows go--->task manager and check python instances and kill or end task i.e kill all python instances. run again using "py manage.py runserver" command. i hope it will be work fine....

Answer 13

On Django 1.11 I had to do this after following instructions in docs https://docs.djangoproject.com/en/1.11/topics/auth/customizing/#substituting-a-custom-user-model

# create default database:
./manage.py migrate

# create my custom model migration:
# running `./manage.py makemigrations` was not enough
./manage.py makemigrations books
# specify one-off defaults

# create table with users:
./manage.py migrate

Answer 14

Just do the following flow

$ django-admin createproject <your project name>

under <your project dict> type django-admin createapp <app name>

under <app name>/admin.py

from django.contrib import admin
from .models import Post
admin.site.register(Post)

Go to the root project. Then $python manage.py migrate

Then it asks for username and password

Answer 15

If You did any changes in project/app then execute:

python manage.py migrate
python manage.py makemigrations
python manage.py createsuperuser

Answer 16

call these command

python manage.py makemigrations
python manage.py migrate

Answer 17

theres four steps for adding a custom user model to django

1. Create a CustomUser model
2. update project/settings.py AUTH_USER_MODEL
3. customize UserCreationForm & UserChangeForm
4. add the custom user model to admin.py

you missed customize forms , add the CustomUser and CustomUserAdmin to admin.site.register() , then makemigrations nd migrate .

#proj_app/forms.py
from django.contrib.auth import get_user_model
from django.contrib.auth.forms import UserCreationForm, UserChangeForm

class CustomUserCreationForm(UserCreationForm):
    class Meta:
            model = get_user_model()
            fields = ('email','username',)

class CustomUserChangeForm(UserChangeForm):
    class Meta:
            model = get_user_model()
            fields = ('email',  'username',)

#proj_app/admin.py
from django.contrib import admin
from django.contrib.auth import get_user_model
from django.contrib.auth.admin import UserAdmin

from .forms import CustomUserCreationForm , CustomUserChangeForm

CustomUser = get_user_model()

class CustomUserAdmin(UserAdmin):
    add_form = CustomUserCreationForm
    form = CustomUserChangeForm
    model = CustomUser
    list_display = ['email','username',]

admin.site.register(CustomUser, CustomUserAdmin)

here we extend the existing UserAdmin into CustomUserAdmin and tell django to use our new forms, custom user model, and list only the email and username of a user also we could add more of existing User fields to list_display
