如何在 Django 5.0.2 和 Django Registration 3.4 中使用 django-registration 创建自定义注册表单

Question

我承认我是 Django 的新手，但我一整天都在为这个问题而头撞墙。我创建了一个新的应用程序并从 django_registration 继承了类，但似乎我的表单数据从未保存过。我的字段显示并可在前端和管理区域访问，但用户注册似乎从未发生，并且我没有收到错误。 （它与标准 django 注册一起工作得很好，但我想扩展它并为未来做好计划。）

表格.py

from django_registration.forms import RegistrationForm
from authentication.models import MyCustomUser
from django import forms

class MyCustomUserForm(RegistrationForm): 
    class Meta(RegistrationForm.Meta):
        model = MyCustomUser
        #fields = "__all__"
        fields = ['username', 'email', 'first_name', 'last_name', 'profile_photo', 'password1', 'password2']

模型.py

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

class MyCustomUser(AbstractUser):
    ROLE_CHOICES = (
        ('APPLICANT', 'Applicant'),
        ('EMPLOYEE', 'Employee'),
        ('ADMIN', 'Admin'),
        (None, 'None')
    )
    role = models.CharField(max_length=30, choices=ROLE_CHOICES)
    profile_photo = models.ImageField()
    #username = forms.CharField(max_length = 100) #this is already handled for us in AbstractUser
    #email  = forms.EmailField(max_length = 100) #this is already handled for us in AbstractUser
    #password1 = forms.CharField(widget = forms.PasswordInput(), max_length = 100) #this is already handled for us in AbstractUser
    #password2 = forms.CharField(widget = forms.PasswordInput(),  max_length = 100) #this is already handled for us in AbstractUser
    first = forms.CharField(max_length = 100 )
    last = forms.CharField(max_length = 100)
    #USERNAME_FIELD = username #this is already handled for us in AbstractUser
    REQUIRED_FIELDS = []

管理员.py

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .forms import MyCustomUserForm
from .models import MyCustomUser

class CustomUserAdmin(UserAdmin):
    add_form = MyCustomUserForm
    #form = CustomUserChangeForm
    model = MyCustomUser
    list_display = ["email", "username", "first_name", "last_name", "profile_photo", "role"]

admin.site.register(MyCustomUser, CustomUserAdmin)

设置.py

AUTH_USER_MODEL = 'authentication.MyCustomUser'

url.py

path('accounts/register/', SignUpView.as_view(), name='django_registration_register')

views.py

from django.shortcuts import render, redirect
from django.views.generic import View
from django.views import generic
from django_registration.views import RegistrationView as BaseRegistrationView
from authentication.forms import MyCustomUserForm

class SignUpView(BaseRegistrationView):#generic.CreateView
    form_class = MyCustomUserForm
    template_name = "authentication/registration_form.html"

我尝试将https://github.com/ubernostrum/django-registration/blob/trunk/src/django_registration/backends/activation/views.py中的方法添加到我的views.py中，但没有区别。我想如果我继承了这个类，那么方法无论如何都是可以访问的。我已经浏览了https://django-registration.readthedocs.io/en/latest/index.html的文档，试图弄清楚我需要做什么，但我不清楚我在这里缺少什么。

您的

MyCustomUser

模型继承自

AbstractUser

，这是正确的，但直接在模型中使用 Django 表单字段（

first

和

last

变量）是不正确的。 模型应该定义数据库字段，而不是表单字段。您应该删除这些并使用 AbstractUser 提供的

first_name

和

last_name

字段，如下所示：

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

class MyCustomUser(AbstractUser):
    ROLE_CHOICES = (
        ('APPLICANT', 'Applicant'),
        ('EMPLOYEE', 'Employee'),
        ('ADMIN', 'Admin'),
        (None, 'None')
    )
    role = models.CharField(max_length=30, choices=ROLE_CHOICES, default=None, blank=True, null=True)
    profile_photo = models.ImageField(upload_to='profile_photos/', blank=True, null=True)  # Specify upload directory and make it optional if you want

这应该可以解决您的问题。
