我正在通過 onetoone 關(guān)系機智配置文件模型擴展 django 用戶模型。我想在創(chuàng)建用戶實例時創(chuàng)建用戶的配置文件，所以我使用 post_save 信號。當(dāng)我創(chuàng)建用戶（使用注冊視圖）時，還創(chuàng)建了一個配置文件空白和空值，這正是我想要的。但是當(dāng)我嘗試使用該用戶登錄時，會出現(xiàn) IntegrityError。視圖.pydef register(request):if request.method == 'POST': user_form = CreatUserForm(request.POST) if user_form.is_valid(): new_user = user_form.save(commit=False) new_user.set_password(user_form.cleaned_data['password']) new_user.save() return render(request,'accounts/registration_done.html',{'new_user':new_user}) else: return render(request,'accounts/registration.html', {'user_form':user_form})else: user_form = CreatUserForm() return render(request,'accounts/registration.html',{'user_form':user_form})@login_requireddef edit_profile(request):if request.method == 'POST': user_edit_form = UserEditForm(instance=request.user,data=request.POST) profile_edit_form = ProfileEditForm(instance=request.user.profile,data=request.POST) if user_edit_form.is_valid() and profile_edit_form.is_valid(): user_edit_form.save() profile_edit_form.save() messages.add_message(request,messages.SUCCESS,'profile updated') return redirect('dashboard') else: return render(request,'accounts/edit_profile.html',{'user_edit_form':user_edit_form, 'profile_edit_form':profile_edit_form})else: user_edit_form = UserEditForm(instance=request.user) profile_edit_form = ProfileEditForm(instance=request.user.profile) return render(request,'accounts/edit_profile.html',{'user_edit_form':user_edit_form, 'profile_edit_form':profile_edit_form})

嘿，當(dāng)您更新特定用戶實例時，將觸發(fā)后保存。
def create_user_profile(sender, instance, created, **kwargs):
Profile.objects.get_or_create(user=instance)
或檢查實例是否是新的
def create_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
