Python 将两个pk传递到url

如果“学年”值已更改，则不会显示404。 我希望数据仅在“学年”和“pk”在url中都具有正确的值时显示

比如说 如果您有以下数据（学年=2020，pk=33） 当您输入url和 两者都是相同的结果

但是，我只想在两个值都正确时显示结果

我真的不知道我的解释是否正确，谢谢

view.py

class StudentDetail(DetailView,FormView):
        model = Student
        template_name = 'student/member.html'
        context_object_name = 'student'
        form_class = AddConsultation
    
        def get_context_data(self, **kwargs):
            context = super().get_context_data(**kwargs)
            context['pk'] = Student.objects.filter(pk=self.kwargs.get('pk'))
            return context

url.py

path('student/<school_year>/<pk>/', views.StudentDetail.as_view(), name='student_detail'),

我将删除

get\u context\u数据

并使用

get\u object\u或

覆盖

get\u object

：

class StudentDetail(DetailView, FormClass):
    model = Student
    template_name = 'student/member.html'
    context_object_name = 'student'
    form_class = AddConsultation

    def get_object(self, queryset=None):
        return get_object_or_404(Student, pk=self.kwargs['pk'], school_year=self.kwargs['school_year'])

其他解决方案可能是：

class StudentDetail(DetailView, FormClass):
    model = Student
    template_name = 'student/member.html'
    context_object_name = 'student'
    form_class = AddConsultation
    slug_field = 'school_year'
    slug_url_kwarg = 'school_year'
    query_pk_and_slug = True

但我发现第一个没那么神奇：）

干杯！它起作用了。get_context_数据和get_对象之间有什么区别？get_对象用于填充模板中的对象变量，get_context_数据用于向模板上下文添加更多内容

class StudentDetail(DetailView, FormClass):
    model = Student
    template_name = 'student/member.html'
    context_object_name = 'student'
    form_class = AddConsultation

    def get_object(self, queryset=None):
        return get_object_or_404(Student, pk=self.kwargs['pk'], school_year=self.kwargs['school_year'])

class StudentDetail(DetailView, FormClass):
    model = Student
    template_name = 'student/member.html'
    context_object_name = 'student'
    form_class = AddConsultation
    slug_field = 'school_year'
    slug_url_kwarg = 'school_year'
    query_pk_and_slug = True
