Question

我正在上Djago在线课程，没有人寻求帮助。希望获得帮助和提示。

我正在学习创建表单（登录/单据）。

到目前为止，我在models.py

from django.db import models
from django.contrib import auth


class User(auth.models.User,auth.models.PermissionsMixin):

    def __str__(self):
        return "@{}".format(self.username)

在forms.py

from django.contrib.auth import get_user_model
from django.contrib.auth.forms import UserCreationForm

class UserCreateForm(UserCreationForm):

    class Meta:
        fields = ('username','email','password1','password2')
        model = get_user_model()

    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        self.fields['username'].label = 'Display Name'
        self.fields['email'].label = 'Email Address'

我想添加其他姓氏作为姓，但是当我在'surname'（class meta的{{1}}中添加fields时出现错误，但是在线培训显示我可以轻松添加其他字段。您能告诉我我做错了什么以及如何添加此字段吗？

当我在forms.py中添加字段'surname'时：

forms.py

它给出以下错误：

from django.contrib.auth import get_user_model
from django.contrib.auth.forms import UserCreationForm

class UserCreateForm(UserCreationForm):

    class Meta:
        fields = ('username','email','surname','password1','password2')
        model = get_user_model()

    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        self.fields['username'].label = 'Display Name'
        self.fields['surname'].label = 'Surname'
        self.fields['email'].label = 'Email Address'

我在raise FieldError(message) django.core.exceptions.FieldError: Unknown field(s) (surname) specified for User中

views.py

Answer 1

首先，您正在使用get_user_model()方法，但是您正在使用自定义User模型。

在您的设置中，设置AUTH_USER_MODEL：

AUTH_USER_MODEL = 'app.User'

然后将surname字段添加到您的User模型中：

class User(auth.models.User):
    surname = models.Charfield()

    def __str__(self):
        return "@{}".format(self.username)

运行并应用迁移。然后，您可以将surname字段添加到表单fields

class UserCreateForm(UserCreationForm):

    class Meta:
        fields = ('username','email','surname','password1','password2')
        model = get_user_model()

    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        self.fields['username'].label = 'Display Name'
        self.fields['surname'].label = 'Surname'
        self.fields['email'].label = 'Email Address'

Answer 2

您需要对forms.py文件进行以下更改：-

from appname.models import USER 
from django.contrib.auth.forms import UserCreationForm

class UserCreateForm(UserCreationForm):

    class Meta:
        fields = ('username','email','surname','password1','password2')
        model = USER

    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        self.fields['username'].label = 'Display Name'
        self.fields['surname'].label = 'Surname'
        self.fields['email'].label = 'Email Address'

Answer 3

# In your forms.py, you need to add new field 'surname'

For Example:-
from django import forms
from django.contrib.auth import get_user_model
from django.contrib.auth.forms import UserCreationForm

class UserCreateForm(UserCreationForm):
    surname = forms.CharField(max_length=20)

    class Meta:
        fields = ('username','email','surname','password1','password2')
        model = get_user_model()

    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        self.fields['username'].label = 'Display Name'
        self.fields['surname'].label = 'Surname'
        self.fields['email'].label = 'Email Address'
