python - AUTH_USER_MODEL 指的是尚未安装和创建的模型 .. AbstractUser 模型无法登录

Question

AUTH_USER_MODEL 错误已在 EDIT3 中解决。通过表单创建用户时，密码仍然不会保存。

我正在使用 Django 1.5 使用新的用户覆盖/扩展功能，我无法通过我的注册表单注册新用户 - 只能通过管理员。通过注册表单注册时，我收到以下错误:

管理器不可用；用户已被替换为“poker.PokerUser”

models.py:

class PokerUser(AbstractUser):
    poker_relate = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True)
    token = models.EmailField()
    USER_CHOICES = (
        ('1', 'Staker'),
        ('2', 'Horse')
    )
    user_type = models.CharField(choices=USER_CHOICES, max_length=10)
    username1 = models.CharField(null=True, blank=True, max_length=40)
    username2 = models.CharField(null=True, blank=True, max_length=40)
    username3 = models.CharField(null=True, blank=True, max_length=40)
    username4 = models.CharField(null=True, blank=True, max_length=40)
    username5 = models.CharField(null=True, blank=True, max_length=40)

PokerUserForm 模型:

class PokerUserForm(UserCreationForm):
    class Meta:
        model = PokerUser
        fields = ('username','password1','password2','email','user_type','token','username1','username2','username3','username4','username5',)

我尝试将 PokerUserForm 模型中的模型更改为使用 get_user_model() 而不是通过设置 model = get_user_model() 显式定义模型 而不是 model = PokerUser 但随后我收到以下错误:

django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'poker.PokerUser' that has not been installed

我的 AUTH_USER_MODEL 设置在我的 settings.py 中，如下所示:

AUTH_USER_MODEL = 'poker.PokerUser'

开始吧 - 我在 views.py 中的注册 View :

def UserRegistration(request):
    player = PokerUser()

    if request.method == 'POST':
        form = PokerUserForm(request.POST, instance=player)
        if form.is_valid():
            player.email_address = form.cleaned_data['email']
            player.user_type = form.cleaned_data['user_type']
            # if player is staker, token is their own email. otherwise their token is their staker's email and
            # their relation is their staker
            if player.user_type == '1' or player.user_type == 'staker':
                player.token = player.email_address
            else:
                player.token = form.cleaned_data['token']
                staker = PokerUser.objects.get(email=player.token)
                player.poker_relate = staker
            player.save()
            return HttpResponseRedirect('/')
    else:
        form = PokerUserForm()
    initialData = {'form': form}
    csrfContext = RequestContext(request, initialData)
    return render_to_response('registration/register.html', csrfContext)

EDIT1:

According to the docs ，则必须重新创建 UserCreationForm 以用于自定义用户类。

我将整个 UserCreationForm 覆盖如下:

class UserCreationForm(forms.ModelForm):
    """
    A form that creates a user, with no privileges, from the given username and
    password.
    """
    error_messages = {
        'duplicate_username': _("A user with that username already exists."),
        'password_mismatch': _("The two password fields didn't match."),
        }
    username = forms.RegexField(label=_("Username"), max_length=30,
        regex=r'^[\w.@+-]+$',
        help_text=_("Required. 30 characters or fewer. Letters, digits and "
                    "@/./+/-/_ only."),
        error_messages={
            'invalid': _("This value may contain only letters, numbers and "
                         "@/./+/-/_ characters.")})
    password1 = forms.CharField(label=_("Password"),
        widget=forms.PasswordInput)
    password2 = forms.CharField(label=_("Password confirmation"),
        widget=forms.PasswordInput,
        help_text=_("Enter the same password as above, for verification."))

    class Meta:
        model = PokerUser
        fields = ('username','password1','password2','email','user_type','token','username1','username2','username3','username4','username5',)

    def clean_username(self):
        # Since User.username is unique, this check is redundant,
        # but it sets a nicer error message than the ORM. See #13147.
        username = self.cleaned_data["username"]
        try:
            PokerUser.objects.get(username=username)
        except PokerUser.DoesNotExist:
            return username
        raise forms.ValidationError(self.error_messages['duplicate_username'])

    def clean_password2(self):
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 and password2 and password1 != password2:
            raise forms.ValidationError(
                self.error_messages['password_mismatch'])
        return password2

    def save(self, commit=True):
        user = super(UserCreationForm, self).save(commit=False)
        user.set_password(self.cleaned_data["password1"])
        if commit:
            user.save()
        return user

这能够解决这个错误:

管理器不可用；用户已被替换为“poker.PokerUser”

现在，用户已创建但无法登录。当我在管理员中检查用户时，所有信息似乎都是正确的，除了密码。在管理员中手动添加密码似乎无法正常工作。尽管如此，通过管理员添加用户仍然可以正常工作。

编辑 2:

我仍然无法以通过注册表单创建的任何 AbstractUser 模型登录。如上所述，我已经完全覆盖了 UserCreationForm，并且无法实现get_user_model() 出现此错误:

AUTH_USER_MODEL 指的是尚未安装的模型“poker.PokerUser”

get_user_model() 的 Django 代码是:

 def get_user_model():
    "Return the User model that is active in this project"
    from django.conf import settings
    from django.db.models import get_model

    try:
        app_label, model_name = settings.AUTH_USER_MODEL.split('.')
    except ValueError:
        raise ImproperlyConfigured("AUTH_USER_MODEL must be of the form 'app_label.model_name'")
    user_model = get_model(app_label, model_name)
    if user_model is None:
        raise ImproperlyConfigured("AUTH_USER_MODEL refers to model '%s' that has not been installed" % settings.AUTH_USER_MODEL)
    return user_model

由于我的 settings.py 中有 AUTH_USER_MODEL = 'poker.PokerUser' 设置，这应该可以工作。我已经通过 Django 控制台验证了这一点:

>>> from django.contrib.auth import get_user_model
>>> settings.AUTH_USER_MODEL
Out[14]: 'poker.PokerUser'
>>> from django.db.models import get_model
>>> app_label, model_name = settings.AUTH_USER_MODEL.split('.')
>>> user_model = get_model(app_label, model_name)
>>> user_model
Out[18]: poker.models.PokerUser

但是，实现仍然无法正常工作。

如果您已经读到这里，谢谢!

EDIT3:

AUTH_USER_MODEL 指的是尚未安装的模型'poker.PokerUser' 已修复。我不小心拥有了在 poker.models 而不是 registration.forms 中重新创建的 UserCreationForm，所以当我运行 get_user_model() 已分配给 poker.PokerUser，但无法解析，因为它已经在该位置。

现在剩下的唯一问题是在创建新用户时，他们的密码不会保存。我通过在此处放置打印语句将其缩小到 UserCreationForm 中的单个方法:

def clean_password2(self):
    password1 = self.cleaned_data.get("password1")
    print password1
    password2 = self.cleaned_data.get("password2")
    print password2
    if password1 and password2 and password1 != password2:
        raise forms.ValidationError(
            self.error_messages['password_mismatch'])
    print password2
    return password2

def save(self, commit=True):
    user = super(UserCreationForm, self).save(commit=False)
    user.set_password(self.cleaned_data["password1"])
    print self.cleaned_data["password1"]
    if commit:
        user.save()
    return user

clean_password2 中的 print password1 和 print password1 语句显示纯文本密码，但 print self.cleaned_data["password1 save 方法中的 "] 为空白。为什么我的表单数据没有传递给 save 方法？

TL;DR AbstractUser 模型创建在管理员和注册表单中都有效，但只有通过管理员创建的用户才能登录。通过注册表创建的用户无法登录，并且似乎在没有密码的情况下保存 - 所有其他信息都正确保存。

我遇到过几次。一直是进口问题。假设我们有 core/models.py，它实现了一个自定义用户并从另一个文件(比如 Else)导入了一个符号:

from Something import Else

class CustomUser(AbstractBaseUser):
    pass

然后我们有另一个使用 CustomUser 并定义 Else 的文件。让我们称之为 something/models.py:

from core.models import CustomUser

class Else(models.Model):
    pass

class AnotherClass(models.model):
    user = models.ForeignKey(CustomUser)

当 core/models.py 去 import Else 时，它​​会评估 something/models.py 并运行到 AnotherClass 定义中。 AnotherClass 使用 CustomUser，但尚未安装 CustomUser，因为我们正在创建它。所以，它会抛出这个错误。

我通过保持 core/models.py 独立解决了这个问题。它不会从我的其他应用中导入太多内容。
