用户注册错误:没有这样的表:auth_user [英] User Registration with error: no such table: auth_user

问题描述

我正在尝试使用 Django 的默认身份验证来处理注册和登录.

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),
)

我尝试删除 db.sqlite3 文件并重新运行 python manage.py syncdb 但我仍然收到此错误消息:

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

推荐答案

更新

您收到此错误可能是因为您使用的是 UserCreationForm 模型表单，其中在 META 中它包含 User(django.contrib.auth.models > User) 作为模型.

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",)

这里您使用的是您自己的自定义身份验证模型，因此尚未创建与 User 相关的表.所以在这里你必须使用你自己的自定义模型表单.在元类中，模型应该是你的 User(books.User) 模型

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
