如果更改“學(xué)年”值，則不會出現(xiàn) 404。我希望僅當(dāng) 'school_year' 和 'pk' 的 url 值都正確時才顯示數(shù)據(jù)。例如，如果您有數(shù)據(jù) (School_Year = 2020, pk = 33)，當(dāng)您輸入 url https://190.0.1/190/190/33和https://190.0.1/190/whatthell/33時 ，兩者都是相同的結(jié)果。但是，我想僅當(dāng)兩個值都正確時才顯示結(jié)果。我真的不知道我解釋是否正確，謝謝。view.pyclass 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 contexturl.pypath('student/<school_year>/<pk>/', views.StudentDetail.as_view(), name='student_detail'),html鏈接<a href='{% url 'student_detail' student.school_year student.pk %}'>models.pyclass Student(models.Model): school_year = models.CharField( max_length=10, choices=SCHOOL_YEAR_CHOICES, default='2021N', verbose_name='school year' ) ... etc

我將使用以下方法刪除get_context_data并覆蓋：get_objectget_object_or_404
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'])
其他解決方案可能是：
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
但我發(fā)現(xiàn)第一個不那么神奇:)
