Django-“用户”对象不可迭代

Question

当我在上下文中传递instance1 ，它给出的错误'User' object is not iterable 。 我想在pk模板中显示名称。 示例http://localhost:8000/users/15/profile-update/ pk=15

 def userProfileUpdate(request, pk):
        if request.method == 'POST':
            u_form = UserUpdateForm(request.POST, instance=User.objects.get(id=pk))
            p_form = UserProfileForm(request.POST, 
                                     request.FILES,
                                     instance=UserProfile.objects.get(user_id=pk))
            if u_form.is_valid() and p_form.is_valid():
                u_form.save()
                p_form.save()
                messages.success(request, 'Profile Updated!!!')
                return redirect('users')
        else:
            instance1 = User.objects.get(id=pk)
            u_form = UserUpdateForm(instance=User.objects.get(id=pk))
            p_form = UserProfileForm(instance=UserProfile.objects.get(user_id=pk))
        context ={
            'object': instance1, # This is giving the error
            'u_form': u_form,
            'p_form': p_form
        }
        return render(request, 'users/userprofile.html', context)

Answer 1

用户request.user代替User.objects.get(id=pk)和request.user.userprofile代替UserProfile.objects.get(user_id=pk))

Answer 2

找到了ans。 它不使用对象名称，而是应该放置与对象不同的名称。 例

object12

context ={
            'object12': instance1, # Change here
            'u_form': u_form,
            'p_form': p_form
        }

在模板中，我们可以将其作为{{ object12.first_name }}
