Question

我有两个模型：UserEdus和Question。

我需要将所有Questions作为其作者的UserEdus。

Models.py

class UserEdus(models.Model):
user = models.OneToOneField(User, on_delete=models.SET_NULL, null=True)

class Question(models.Model):
author = models.ForeignKey(UserEdus, null=False)

Views.py

class MyQuestionListView(generic.ListView):
    model = Question
    paginate_by = 10
    queryset = Question.objects.filter(author=User.useredus)
    template_name = 'edus/myquestion_list.html'

此查询集返回int() argument must be a string, a bytes-like object or a number, not 'ReverseOneToOneDescriptor'

如果我这样做

queryset = User.useredus.question.all()

返回'ReverseOneToOneDescriptor' object has no attribute 'question'

虽然在模板级别上，我可以使用

获得正确的结果

{% for question in user.useredus.question_set.all %}

Answer 1

如果您想根据请求用户动态设置查询集，那么您将不得不重写get_queryset方法。所以做这样的事情：

class MyQuestionListView(generic.ListView):
    model = Question
    paginate_by = 10
    template_name = 'edus/myquestion_list.html'

    def get_queryset(self):
        return self.request.user.useredus.question_set.all()

基于当前用户
