我如何在 Django 中注册自定义用户模型（一种类型）？

Question

如何在 django 中使用自定义用户模型 (OneToOneField) 创建正确的登录和注册？我使用的是普通 HTML 表格。我正在使用 Django 2.2.3。我的数据库是 Postgeres。

你好，我创建了一个可以登录并注册的网站，但是......我需要自定义用户模型......所以我创建了一个自定义用户模型（在一个字段上使用一个），但我不我不知道如何为其创建登录和注册...所以我尝试了...但它无法正常工作...我无法在我的自定义用户模型中使用其他字段进行注册，它只注册了 User ，而不是 Profile 并给我这个错误“'Manager' object has no attribute 'create_profile'”。对于我的登录……我认为它是通过 Django 的用户登录的。我正在使用 Django 2.2.3。我的数据库是 Postgeres。我怎样才能创建正确的登录和注册？

我的models.py:

from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver

class Profile(models.Model):
     user           =   models.OneToOneField(User,on_delete=models.CASCADE)
     address        =   models.TextField(max_length=500)
     phone          =   models.CharField(max_length=50)
     postcode       =   models.CharField(max_length=50, blank=True)
     isManager      =   models.BooleanField(default=False)
     isAccountment  =   models.BooleanField(default=False)
     isStorekeeper  =   models.BooleanField(default=False)
     isSeller       =   models.BooleanField(default=False)
     isNormal       =   models.BooleanField(default=True)

     def __str__(self):
         return self.user.email

def create_profile(sender,**kwargs):
    if kwargs['created']:
        user_profile=Profile.objects.create(user=kwargs['instance'])
post_save.connect(create_profile,sender=User)

我的 views.py :

from django.shortcuts import render , redirect
from django.contrib.auth.models import User
from accounts.models import Profile
from django.contrib import auth
from django.contrib.auth.decorators import login_required
from django.db.models import Q
from django.core.mail import send_mail



def signup(request):
if request.method == 'POST':
    #USER HAS INFO AND WANTS ACCOUNT___NOW!
    if request.POST['password1'] == request.POST['password2']:
        try:
            user =  User.objects.get(username=request.POST['username'],)
            return render(request,'accounts/signup.html',{'error':'Username Exist...Try Something Else !','username':user})
        except User.DoesNotExist :
            user = User.objects.create_user(request.POST['username'] , password = request.POST['password1'],first_name=request.POST['fname'],last_name=request.POST['lname'],email=request.POST['email'],)
            profile = user.profile # because of signal and one2one relation
            profile.phone = request.POST['mobile_num']
            profile.address = request.POST['address']
            profile.postcode = request.POST['post_code']
            profile.save()
            auth.login(request,user)              
            return redirect('homepage')
    return render(request,'accounts/signup.html',{'error':"Passwords Don't Match"})
else:
    #USER wants enter info
    return render(request,'accounts/signup.html')    
def login(request):
    if request.method == 'POST':
        user=auth.authenticate(username=request.POST['username'],password=request.POST['password'])
        if user is not None:
            auth.login(request,user)
            return render(request,'products/home.html')
            #return redirect('homepage')
        else:
            return render(request,'accounts/login.html',{'error':'Username Or Password Is Incorrect !'})
    else:
        return render(request,'accounts/login.html')

def logout(request):
    if request.method =='POST':
        auth.logout(request)
        return redirect('homepage')
@login_required
def myproducts(request):
        user_id=request.user.id
        products=Products.objects.all().filter(creator__exact=user_id)
        return render(request,'accounts/myproducts.html',{'products':products})
def about_us(request):
    return render(request,'accounts/aboutus.html')
def connect_us(request):
    return render(request,'accounts/connectus.html')

这是我的表单页面：

{% extends 'base.html' %}

{% block content%}
<h1 style="margin-left:490px"> Register </h1>
<div class="left" style="margin-left:465px">
<form method="POST" action="{% url 'signup' %}">
  {% csrf_token %}
  First Name:
  <br/>
  <input type="text" name="fname"/><br/>
  Last Name:
  <br/>
  <input type="text" name="lname"/><br/>
  UserName:
  <br/>
  <input type="text" name="username"/><br/>
  Mobile:
  <br/>
  <input type="text" name="mobile_num"/><br/>
  Email:
  <br/>
  <input type="text" name="email"/><br/>
  Address:
  <br/>
  <input type="text" name="address"/><br/>
  Post Code
  <br/>
  <input type="text" name="post_code"/><br/>
  Password:
  <br/>
  <input type="password" name="password1"/><br/>
  Confirm password:
  <br/>
  <input type="password" name="password2"/>
  <br/>
  <br/>
  <input class="btn btn-primary" type="submit" name="signup-btn" value="SignUp" style="margin-top:-23px;margin-left:49px;"/>
</form>
{% if error %}
<p style="color:red">{{error}}</p>
<br/>
{% endif%}
</div>
{% endblock %}

请帮忙。

我认为您混淆了 signals and manager 方法。您不能将信号方法称为管理器方法。

我的意思是create_profile()是一个信号，当User被创建时会自动触发。因此，您应该创建 User 实例，而不是创建 Profile。像这样：

def signup(request):
    if request.method == 'POST':
        #USER HAS INFO AND WANTS ACCOUNT___NOW!
        if request.POST['password1'] == request.POST['password2']:
            try:
                # rest of the code...
            except User.DoesNotExist :
                user = User.objects.create_user(username=request.POST['username'] ,first_name=request.POST['fname'],last_name=request.POST['lname'],email=request.POST['email'],password = request.POST['password1'])
                profile = user.profile # because of signal and one2one relation
                profile.phone_no = request.POST['phone'] 
                profile.post_code = request.POST['post_code']
                profile.save()
                auth.login(request,user)
                return redirect('homepage')
        return render(request,'accounts/signup.html',{'error':"Passwords Don't Match"})
    else:
        #USER wants enter info
        return render(request,'accounts/signup.html')

但是，当您尝试创建 User 时，您可能会遇到错误 NOT NULL constraint failed，因为在 Profile 中有两个字段（phone 和 address) 不为空。所以我建议你制作它们 null=True。
