尝试将循环插入\uu init__

Question

我在Django数据库中有一个对象Quiz，它包含test_name和num_of_questions列。我试图在下一步中获得所有render name、count questions和render列的值（使用适当的测验名称）。我是新来的，所以我想问，我做得对吗

from .models import Quiz 

class rendered():
    quizs = Quiz.objects.all()
    for quiz in quizs:
        quizname = quiz.test_name
        n_o_q = quiz.num_of_questions
        tup = (quizname, n_o_q)


    def __init__(self, quiz_sum):
        self.quiz_sum = tup
        super(rendered, self).__init__()
