Pagination in Django not working as expected

Question

I wanted pagination for all the courses available and that was easy to achieve. But now I'm stuck because I wanted pagination for faculties also, which will show specific courses of the accessed faculty. I have 4 models: faculties, departments, studies, and courses. The pagination will show for faculties as well, but the problem is that if I try to go to the second page, it will redirect me to the second page of all courses list. Or, if I change page on all courses and then try to access a faculty, no course will show at all in the faculty.

def index(request):
    course_list = Course.objects.all()
    page = request.GET.get('page', 1)
    paginator = Paginator(course_list, 1)
    try:
        courses = paginator.page(page)
    except PageNotAnInteger:
        courses = paginator.page(1)
    except EmptyPage:
        courses = paginator.page(paginator.num_pages)
    faculty_list = Faculty.objects.all()
    page = request.GET.get('page2', 1)
    paginator = Paginator(faculty_list, 1)
    try:
        faculties = paginator.page(page)
    except PageNotAnInteger:
        faculties = paginator.page(1)
    except EmptyPage:
        faculties = paginator.page(paginator.num_pages)
    context = {'courses': courses,
               'faculties': faculties,
               'departments': Department.objects.all(),
               'studies': StudyProgramme.objects.all(),
               'teachers': Teacher.objects.all()
               }
    return render(request, 'courses/index.html', context)

Answer 1

paginator = Paginator(course_list, 1)

paginator = Paginator(faculty_list, 1)

Changing your second instance name to paginator_two would solve your problem
