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: xyz@gmail.com
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:
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 #7:
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 #8:
Just perform migrations before registering the user.
