Question

所以我想知道Django 1.7.1中是否有可能像reverse Tabular Inline这样做：

现在我有：

型号：

class UserProfile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)

我希望我的内联类似：

class UserInline(admin.TabularInline):
    model = get_user_model()

class UserProfileAdmin(admin.ModelAdmin):
    inlines = [
        UserInline,
    ]

但我得到<class 'users.admin.UserInline'>: (admin.E202) 'auth.User' has no ForeignKey to 'users.UserProfile'.

我真的需要只使用UserProfile来创建/编辑新用户，而不是像内联文档所建议的那样。

任何人都知道如何实现这一目标？

Answer 1

有几种方法可以在Django中扩展用户模型，看起来你选择了错误的用例。

尝试使用继承来扩展内置用户模型。

class UserWithProfile(AbstractBaseUser):
    ...
    date_of_birth = models.DateField()
    relationship_status = models.IntegerField(choices=RS)
    height = models.FloatField()
    ...
    REQUIRED_FIELDS = ['date_of_birth', 'height']

在settings.py：

AUTH_USER_MODEL = 'myapp.UserWithProfile'

我发现了一种更简单的方法，通过创建自己的自定义模型，我可以实现这一点：

class GirlModelForm(forms.ModelForm):
    username = forms.CharField(
        label=_('username'), max_length=30,
        help_text=_(
            'Required. 30 characters or fewer. Letters, digits and @/./+/-/_ only.'
        ),
        validators=[
            validators.RegexValidator(
                r'^[\w.@+-]+$', _('Enter a valid username.'), 'invalid'
            )
        ])
    first_name = forms.CharField(label=_('first name'), max_length=30)
    last_name = forms.CharField(label=_('last name'), max_length=30)
    email = forms.EmailField(label=_('email address'))

    # The attribute required must be False because of the clean() workaround
    user = forms.ModelChoiceField(
        queryset=get_user_model().objects.all(), required=False
    )

    class Meta:
        model = Girl
        # fields = [
        #     'degree', 'extra_field'
        # ]

    def __init__(self, *args, **kwargs):
        if not kwargs.get('initial'):
            kwargs['initial'] = {}

        if kwargs.get('instance'):
            kwargs['initial'].update({
                'username': kwargs['instance'].user.username,
                'first_name': kwargs['instance'].user.first_name,
                'last_name': kwargs['instance'].user.last_name,
                'email': kwargs['instance'].user.email,
            })
        super(GirlModelForm, self).__init__(*args, **kwargs)

    def clean(self):
        """
        This is a nasty workaround and it exists so that we can create/edit
        the user directly in the Userprofiles. The motive is referenced here
        http://stackoverflow.com/q/27235143/977622 and basically the idea is
        to make the built in user NOT REQUIRED and GET or CREATE the user
        object and create a new attribute in the cleaned_data with the user
        object
        """
        cleaned_data = super(GirlModelForm, self).clean()
        user, created = get_user_model().objects.get_or_create(
            email=cleaned_data['email'],
            defaults={
                'first_name': cleaned_data['first_name'],
                'last_name': cleaned_data['last_name'],
                'username': cleaned_data['username'],
            }
        )

        if not created:
            # If the user exists update it
            user.first_name = cleaned_data['first_name']
            user.last_name = cleaned_data['last_name']
            user.username = cleaned_data['username']

        user.save()
        cleaned_data['user'] = user

也许有更好的方法可以做到这一点，但这是我能够做的，而无需重做我的模型
