Question

我試圖建立一個自定義的註冊到我的網站，所以我使用了一個註冊配置文件模型。

我遇到這個錯誤提交，我提出讓剛註冊的電子郵件確認後用戶的完整個人資料信息的表格後。 看該圖

我的一些代碼：

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) 
    birth_date = models.DateField(null=True, blank=True) 
    birth_place = models.CharField(max_length=80, verbose_name= ("Lieu de 
    Naissance")) 
    email_confirmed = models.BooleanField(default=False) 
    adress = models.CharField(max_length=80, verbose_name=("Adresse")) 
    adress_complement = models.CharField(max_length=80, verbose_name= 
    ("Complément d'Adresse")) 
    city = models.CharField(max_length=80, verbose_name=("Ville")) 
    zip_code = models.IntegerField(null=True, blank=True) 
    drive_licence_num = models.CharField(max_length=80, verbose_name=("N° du 
    Permis de conduire")) 
    social_secu_num = models.IntegerField(null=True, blank=True) 
    phone_number = models.IntegerField(null=True, blank=True) 

    @receiver(post_save, sender=User) 
    def update_user_profile(sender, instance, created, **kwargs): 
    if created: 
    Profile.objects.create(user=instance) 
    instance.profile.save() 

forms.py

from django import forms 
from django.contrib.auth.forms import UserCreationForm 
from django.contrib.auth.models import User 
from mysite.core.models import Profile 

class SignUpForm(UserCreationForm): 
    email = forms.EmailField(max_length=254, help_text='Required. Inform a 
      valid email address.') 
    class Meta: 
     model = User 
     fields = ('first_name', 'last_name', 'email', 'username', 'password1', 
       'password2',) 

class ProfileForm(forms.ModelForm): 
    class Meta: 
    model = Profile 
    fields = ('birth_date','birth_place', 'adress', 'adress_complement', 
       'city', 'zip_code', 'drive_licence_num', 'social_secu_num', 
       'phone_number') 

views.py（complete_profile視圖）

def complete_profile(request): 
    #if email_confirmed == True: 
    if request.user.is_authenticated(): 
     if request.method == 'POST': 

      form = ProfileForm(request.POST) 
      if form.is_valid(): 
       form.save() 

       return render(request, 'home.html') 
     else: 
      form = ProfileForm() 
      return render(request, 'complete_profile.html', {'form': form}) 
    else: 
     return render(request, 'login.html') 

Answer 1

您可能需要實例request.user.profile傳遞到窗體。

def complete_profile(request): 
    if request.user.is_authenticated(): 
     if request.method == 'POST': 
      form = ProfileForm(request.POST, instance=request.user.profile) 
      if form.is_valid(): 
       #form.instance.user = request.user 
       form.save() 
      return render(request, 'home.html') 
     else: 
      form = ProfileForm() 
      return render(request, 'complete_profile.html', {'form': form}) 
    else: 
     return render(request, 'login.html') 

Answer 2

form = ProfileForm(request.POST,instance=request.user.profile) 
      if form.is_valid(): 
       form.save() 

試試這個
