User Registration with error: no such table: auth_user

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.

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',
        )

./manage.py migrate

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

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.

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

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.

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

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

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….

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

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

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

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

call these command

python manage.py makemigrations
python manage.py migrate

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

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

Just perform migrations before registering the user.

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

For custom forms( if you have made your own forms) use this command to migrate

python manage.py migrate –run-syncdb

I have no idea what I did wrong but got to the point where I decided to clear the whole database. So I ran the command:

python manage.py flush 

After that my database was clear then I ran the commands;

python manage.py makemigrations
python manage.py migrate

then:

python manage.py createsuperuser

That worked for me.
