Python 如何在django中使用auth_用户模型和cutom模型字段创建自定义注册表

我是django的新手，我有自定义的用户模型，带有额外的状态和标题模型。到目前为止，我已经完成了数据库部分，如何使用foreignkey字段为cutom用户模型创建注册表。 我的车型类别代码：

from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.contrib.auth.models import AbstractUser

class Title(models.Model):
value = models.CharField(max_length=100, null=True, blank=True)

class Meta:
    db_table = 'title'

class Status(models.Model): 
value = models.CharField(max_length=100, null=True, blank=True)

class Meta:
    db_table = 'status'

class User(AbstractUser):

filenumber = models.CharField(max_length=9, null=True, blank=True)
personalemail = forms.EmailField(required=True)
intakeyear = models.IntegerField(null=True, blank=True)
title = models.ForeignKey(Title, on_delete=models.CASCADE, null=True, blank=True)
status = models.ForeignKey(Status, on_delete=models.CASCADE, null=True, blank=True)

My settings.py：

AUTH_USER_MODEL = 'student.User'# changes built-in user model to ours

如何创建用户注册表单字段，如 名字、姓氏、标题、状态、电子邮件、个人电子邮件、密码、密码确认。我在用户模型标题和状态（foreignkey字段）以及文件号、intakeyear和personalemail中添加了额外的字段

My form.py文件：

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from django.forms import ModelForm

from student.models import User
from student.models import Title, Statu

class StudentNewRegistrationForm(forms.ModelForm):
title = forms.CharField(required=True)
intakeyear = forms.IntegerField(required=True)
email = forms.EmailField(required=True)
personalemail = forms.EmailField(required=True)
status = forms.CharField(required=True)


def __init__(self, *args, **kwargs):
    super(StudentNewRegistrationForm, self).__init__(*args, **kwargs)
    title = [('', 'Choose a title')]
    title.extend(Title.objects.values_list('id', 'value'))
    self.fields['title'] = forms.ChoiceField(choices=title)

    status = [('', 'Choose a status')]
    status.extend(Status.objects.values_list('id', 'value'))
    self.fields['status'] = forms.ChoiceField(choices=status)

class Meta:
    model = User
    fields = ['username','first_name','last_name','email','password1',
            'password2''title','status','intakeyear','personalemail'
    ]

def save(self, commit=True):
    user = super(StudentNewRegistrationForm, self).save(commit=False)
    user.first_name = self.cleaned_data['first_name']
    user.last_name = self.cleaned_data['last_name']
    user.email = self.cleaned_data['email']
    user.personalemail = self.cleaned_data['email']
    user.title = self.cleaned_data['title']
    user.intakeyear = self.cleaned_data['intakeyear']
    user.status = self.cleaned_data['status']
    user.password1 = self.cleaned_data['password1']
    user.password2 = self.cleaned_data['password2']

    if commit:
        user.save()
    return user

views.py：

from django.shortcuts import render, redirect
from django.urls import reverse
from django.contrib.auth.models import User
from django.contrib.auth import update_session_auth_hash
from django.contrib.auth.decorators import login_required
from .forms import StudentNewRegistrationForm

def student_new_registration(request):
  if request.method == 'POST':
    form = StudentNewRegistrationForm(request.POST)
    if form.is_valid():
        form.save()
        return redirect(reverse('student:home'))

else:
    form = StudentNewRegistrationForm()

    args = {'form': form}
    return render(request, 'student/studentnewregistrationform.html', args)

studentnewregistrationform.html：

请帮助我提前感谢任何人

因为

标题

和

状态

模型的字段是

外国

您应该使用

模型选择字段

而不是

选择字段

：

def __init__(self, *args, **kwargs):
    super(StudentNewRegistrationForm, self).__init__(*args, **kwargs)
    self.fields['title'] = forms.ModelChoiceField(queryset=Title.objects.all(), empty_label='Choose a title')

    self.fields['status'] = forms.ModelChoiceField(queryset=Status.objects.all(), empty_label='Choose a status')

要显示值而不是ID，只需将

\uu str\uuu（）

方法添加到

Status

和

Title

模型：

class Title(models.Model):
    ...
    def __str__(self):
        return.self.value

class Status(models.Model): 
    ...
    def __str__(self):
        return.self.value 

---

由于

title

和

status

模型的字段是

ForeignKyy

您应该使用

modelcoocefield

而不是像这样使用

ChoiceField

：

def __init__(self, *args, **kwargs):
    super(StudentNewRegistrationForm, self).__init__(*args, **kwargs)
    self.fields['title'] = forms.ModelChoiceField(queryset=Title.objects.all(), empty_label='Choose a title')

    self.fields['status'] = forms.ModelChoiceField(queryset=Status.objects.all(), empty_label='Choose a status')

要显示值而不是ID，只需将

\uu str\uuu（）

方法添加到

Status

和

Title

模型：

class Title(models.Model):
    ...
    def __str__(self):
        return.self.value

class Status(models.Model): 
    ...
    def __str__(self):
        return.self.value
