Question

我有这个错误 --> raise TypeError("'class Meta' 的属性无效：%s" % ','.join(meta_attrs)) TypeError：'class Meta' 的属性无效：模型

我想创建人们可以注册的页面，但我有这个错误。如何解决？

我用谷歌搜索，但找不到原因。有什么问题？

Answer 1

您在此处定义Model，但您可能想要定义ModelForm。注意ModelForm 的Meta 使用model，而不是model<s>s</s>：

from django import forms
from django.contrib.auth.models import User

class SignUp(forms.ModelForm):
    class Meta:
        model = User
        fields = '__all__'

在创建User 对象的情况下，最好从UserCreationForm 继承，因为这会将散列 密码存储在数据库中：

from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User

class SignUp(UserCreationForm):
    class Meta:
        model = User
        fields = '__all__'

通过使用通用ModelForm，它将原始密码存储在表单中，然后身份验证将失败（因为这会检查哈希密码）。

Answer 2

应该是ModelForm而不是models.Model

from django.contrib.auth.models import User
from django.forms import ModelForm
class SignUp(ModelForm):
    class Meta:
        model=User
        fields = [add your fields here]

Answer 3

注释掉

'rest_framework.authtoken',

那么你就可以进行迁移和迁移
