将字段中的对象排序为多个

燃气轮机试验-许多现场模型试验。我需要用这种奇怪的算法对测试进行排序,但问题不同。在所有操作之后,我得到一个排序的测试列表,并将它们添加到manytomy字段中。但是当我从这个字段获取值测试时,它们是按从最小的id测试到最大的id测试的顺序显示的。如何按顺序将测试添加到此字段?

    tests = Test.objects.all()
    gt = GroupTest.objects.create(title=name, user=user)

    #code

    import random
    tests_array = []
    tests_go = []

    for reading in ReadingForTest.objects.all():
        if tests.filter(reading=reading).count() != 0:
            tests_array.append(tests.filter(reading=reading))

    tests_list = tests.filter(reading__isnull=True)

    while len(tests_list) > 0:
        number = random.randint(0, 5)
        tests_array.append(tests_list[:number])
        tests_list = tests_list[number:]

    seq = [x for x in range(len(tests_array))]

    random.shuffle(seq)

    for i in seq:
        tests_go.extend(tests_array[i])

    tests_go = tests_go[:number_of_questions]

    print_arr = []
    for test in tests_go:
        print_arr.append(test.id)
        gt.tests.add(test)

    print(print_arr)
    print([x.id for x in gt.tests.all()])
