Question

#models.py 

class Profile(models.Model): 
    user = models.OneToOneField(settings.AUTH_USER_MODEL) 
    birthday = models.DateField(blank=True, null=True) 

我延長django.contrib.auth.views.models.User與附加infomations諸如生日等 的問題是，我無法與request.user.profile訪問birthday在views.py。 我不得不使用額外的小部件來使應用更直觀。

我做了這樣的：

#forms.py 
class ProfileEditForm(forms.ModelForm): 
    birthday = forms.DateField(widget=extras.SelectDateWidget) 

    class Meta: 
     model = Profile 
     fields = ('photo', 'phone_num', 'nationality', 'gender') 

#views.py 
@login_required 
def edit(request): 
    if request.method == 'POST': 
     user_form = UserEditForm(instance = request.user, 
           data = request.POST) 
     profile_form = ProfileEditForm(instance = request.user.profile, 
             data = request.POST, 
             files = request.FILES) 
     if user_form.is_valid() and profile_form.is_valid(): 
      request.user.profile.birthday = user_form.cleaned_data['birthday'] 
      user_form.save() 
      profile_form.save() 
    else: 
     user_form = UserEditForm(instance=request.user) 
     profile_form = ProfileEditForm(
      instance = request.user.profile 
     ) 
    return render(request, 
        'views/edit_profile.html', 
        {'user_form' : user_form, 
        'profile_form' : profile_form})

正如@Alasdair提到的，你需要糾正UserEditForm類。回到自定義小部件，你可以做

class ProfileEditForm(forms.ModelForm): 
    class Meta: 
     model = Profile 
     fields = ('photo', 'phone_num', 'nationality', 'gender', 'birthday') 
     widgets = { 
      'birthday': extras.SelectDateWidget, 
     }
