I am trying to use Django’s default Auth to handle register and log in.
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'
books.models.py:
class User(AbstractUser):
account_balance = models.DecimalField(max_digits=5, decimal_places=2, default=0)
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,})
urls.py:
urlpatterns = patterns('',
(r'^accounts/login/$', login),
(r'^accounts/logout/$', logout),
(r'^accounts/profile/$', profile),
(r'^accounts/register/$', register),
)
I tried deleting the db.sqlite3 file and re-ran python manage.py syncdb but I still get 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

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.
Method 1
./manage.py migrate
If you’ve just enabled all the middlewares etc this will run each migration and add the missing tables.
Method 2
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: <a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="fc848586bc9b919d9590d29f9391">[email protected]</a> Password: Password (again): Superuser created successfully.
Method 3
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
Method 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.
Method 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
Method 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
Method 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',
)
Method 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
Method 9
For custom forms( if you have made your own forms) use this command to migrate
python manage.py migrate –run-syncdb
Method 10
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
Method 11
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
Method 12
Just perform migrations before registering the user.
Method 13
theres four steps for adding a custom user model to django
- Create a CustomUser model
- update project/settings.py AUTH_USER_MODEL
- customize UserCreationForm & UserChangeForm
- 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
Method 14
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.
Method 15
python manage.py makemigrations then → python manage.py migrate fixes it.
Assuming Apps defined/installed in settings.py exist in the project directory.
Method 16
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….
Method 17
If You did any changes in project/app then execute:
python manage.py migrate python manage.py makemigrations python manage.py createsuperuser
Method 18
call these command
python manage.py makemigrations python manage.py migrate
