Django中的多个分页不起作用，正在重定向

Question

我已经为此挣扎了一段时间，我已经接近了一些东西。我有四个模型，通过外键按以下顺序相互绑定：Faculty>；部门>；研究程序>；课程。我创建了分页，搜索我所有的课程。现在我想为只属于特定教员的课程创建分页。例如，我总共有3门课程，其中2门属于信息学系，1门属于医学系，对于每门课程，我需要按每页1门课程分页。 经过多次尝试，我想使用faculties id作为一种进行单独分页的方法，但没有成功。。显示教员的所有课程，而不是仅显示1个，如果单击“下一步”，我将重定向到所有课程的分页。我不知道如何解决这个问题：

@login_required def index(request): query_list = Course.objects.all() query = request.GET.get('q') if query: query_list = query_list.filter(Q(name__icontains=query)) paginator = Paginator(query_list, 1) page = request.GET.get('page') faculty_id = request.GET.get('faculty_id') courses_to_display = None try: courses = paginator.page(page) except PageNotAnInteger: courses = paginator.page(1) except EmptyPage: courses = paginator.page(paginator.num_pages) if not faculty_id: courses_to_display = courses faculties = Faculty.objects.all() for faculty in faculties: f_courses = [] departments = faculty.department_set.all() for department in departments: studies = department.studyprogramme_set.all() for study in studies: for course in study.course_set.all(): f_courses.append(course) paginated_courses = Paginator(f_courses, 1) try: fp_courses = paginated_courses.page(page) except PageNotAnInteger: fp_courses = paginated_courses.page(1) except EmptyPage: fp_courses = paginated_courses.page(paginated_courses.num_pages) faculty.paginated_courses = fp_courses if faculty_id: courses_to_display = fp_courses context = { 'courses': courses_to_display, 'faculties': faculties, 'departments': Department.objects.all(), 'studies': StudyProgramme.objects.all(), 'teachers': Teacher.objects.all() } return render(request, 'courses/index.html', context)
