不正确的配置：创建没有＆＃39;字段的ModelForm＆＃39; 属性或＆＃39;排除＆＃39;属性被禁止;形成 CustomUserChangeForm需要更新。

from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from login1.models import CustomUser


class CustomUserCreationForm(UserCreationForm):
    def __init__(self, *args, **kargs):
        super(CustomUserCreationForm, self).__init__(*args, **kargs)
        del self.fields['username']

    class Meta:
       model = CustomUser
       fields = ("email",)

class CustomUserChangeForm(UserChangeForm):
    def __init__(self, *args, **kargs):
        super(CustomUserChangeForm, self).__init__(*args, **kargs)
        del self.fields['username']

    class Meta:
        model = CustomUser

Answer 1

当你创建一个ModelForm时，它希望你指定在模板中显示哪些字段，即当你在html中执行{{form}}时，你会期望某些字段能够正确呈现吗？因此，在这种情况下，您必须指定fields属性。

class CustomUserChangeForm(UserChangeForm):      
    def __init__(self, *args, **kargs):
        super(CustomUserChangeForm, self).__init__(*args, **kargs)       
        del self.fields['username']

    class Meta:
        model = CustomUser
        fields = '__all__' or ['your_field']

Answer 2

您需要在CustomUserChangeForm.Meta类中定义应在表单中包含哪些模型字段：

class CustomUserChangeForm(UserChangeForm):
    def __init__(self, *args, **kargs):
        super(CustomUserChangeForm, self).__init__(*args, **kargs)
        del self.fields['username']

    class Meta:
        model = CustomUser
        fields = '__all__'  #<-- add this or name fields you want to include as sequence
