详细信息在代码中，它本身就说明了这一点。我有一个配置文件模型，其中的字段不在User中，我需要制作一个表单来填充User和Profile中的字段：

class Profile(models.Model):
    user = models.OneToOneField(
        to=User,
        on_delete=models.CASCADE
        )
    rating = models.IntegerField(default=0, blank=False)
    avatar = models.ImageField()
    
    def __str__(self):
        return self.user.string()
    
    def absolute_url(self):
        return f"/post/{self.pk}/"
    
    class Meta:
        db_table = 'profile'
        ordering = ['-user']

class SignUpForm(UserCreationForm):
    username = UsernameField(
        max_length=256,
        label=_('RegisterUsername'),
        widget=forms.TextInput(
            attrs= {
                'class': "form-control"
            }
        ),
    )
    email = forms.CharField(
        max_length=320,
        label=_('RegisterEmail'),
        widget=forms.EmailInput(
            attrs= {
                'class': "form-control"
            }
        ),
    )
    nickname = forms.CharField(
        max_length=256,
        label=_('RegisterUsername'),
        widget=forms.TextInput(
            attrs= {
                'class': "form-control"
            }
        ),
    )
    password1 = forms.CharField(
        max_length=256,
        label=_('RegisterPassword1'),
        widget=forms.PasswordInput(
            attrs= {
                'class': "form-control"
            }
        ),
    )
    password2 = forms.CharField(
        max_length=256,
        label=_('RegisterPassword2'),
        widget=forms.PasswordInput(
            attrs= {
                'class': "form-control"
            }
        ),
    )
    avatar = forms.ImageField(
        label=_('UploadAvatar'),
        widget=forms.FileInput(
            attrs= {
                'class': "btn btn-outline"
            }
        ),
    )
    
    class Meta:
        model = Profile
        fields = [
            'username', 
            'email'
            'nickname'
            'password1', 
            'password2', 
            'avatar', 
        ]

django.core.exceptions.FieldError:为配置文件指定的未知字段（emailnicknamepassword1）
我以为会有效果...
