示例1: get_context_data
# 需要導入模塊: from students.models import Student [as 別名]
# 或者: from students.models.Student import get_current [as 別名]

context = super().get_context_data(**kwargs)
exam_rooms = ExamRoom.objects.filter(available=True)
context['student_count'] = Student.get_current(want_exam=True).order_by('name', 'prename').count()
context['free_places_1'] = sum([exam_room.capacity(1) for exam_room in exam_rooms])
context['free_places_2'] = sum([exam_room.capacity(2) for exam_room in exam_rooms])
