使用OneToOne字段和用戶模型創建User Profile頁面

Question

我目前使用的是Django all-auth，它有一個/ accounts/profile頁面，我想用創建/填充更新用戶信息的表單。

我有一個老師字段，它擴展了使用OneToOne字段的用戶模型。

models.py

class Teacher(models.Model): 
    user = models.OneToOneField(User, on_delete=models.PROTECT, related_name='Teacher') 
    bio = models.TextField(max_length=500, blank=True) 
    availability = models.BooleanField(default=False) 
    teacher_logo = models.FileField() 

這個老師模型是我希望用戶在/帳號/更新個人資料的內容。

forms.py

class UserForm(forms.ModelForm): 
    class Meta: 
     model = User 
     fields = ('first_name', 'last_name', 'email') 

class TeacherForm(forms.ModelForm): 
    class Meta: 
     model = Teacher 
     fields = ('availability', 'bio','teacher_logo') 

views.py

@login_required 
@transaction.atomic 
def update_profile(request): 
    if request.method == 'POST': 
     user_form = UserForm(request.POST, instance=request.user) 
     teacher_form = TeacherForm(request.POST, instance=request.user.teacher) 
     if user_form.is_valid() and teacher_form.is_valid(): 
      user_form.save() 
      teacher_form.save() 
      messages.success(request, _('Your profile was successfully updated!')) 
      return redirect('users:index') 
     else: 
      messages.error(request, _('Please correct the error below.')) 
    else: 
     user_form = UserForm(instance=request.user) 
     teacher_form = TeacherForm(instance=request.user.teacher) 
    return render(request, 'accounts/profile.html', { 
     'user_form': user_form, 
     'teacher_form': teacher_form 
    }) 

模板用戶/ profile.html

<form method="post"> 
    {% csrf_token %} 
    {{ user_form.as_p }} 
    {{ teacher_form.as_p }} 
    <button type="submit">Save changes</button> 
</form> 

urls.py

url(r'^profile/$', views.update_profile, name='Update-Profile') 

我可以使用更新的觀點，但後來我需要在URL，這似乎是這樣做的一個不正確的方法來指定;另外，用戶將能夠編輯其他配置文件。

當我運行上述內容時，我得到一個抱怨，'用戶'對象沒有屬性'老師'。

當我刪除.teacher從TeacherForm(instance=request.user.teacher)它加載頁面的形式，但是當我更新，它仍然給了我同樣的抱怨

EDIT（在views.py兩地刪除）：models.py額外

@receiver(post_save, sender=User) 
def create_user_profile(sender, instance, created, **kwargs): 
    if created: 
     Teacher.objects.create(user=instance) 

@receiver(post_save, sender=User) 
def save_user_profile(sender, instance, **kwargs): 
    instance.Teacher.save() 

Answer 1

設置相關的名稱爲Teacher，所以你需要：

teacher_form = TeacherForm(instance=request.user.Teacher) 
#            ^^^^ 

或更好的設置related_name爲「老師」

class Teacher(models.Model): 
    user = models.OneToOneField(
     User, 
     on_delete=models.PROTECT, 
     related_name='teacher') 
#      ^^^
