如何将表单保存在数据库中（django）

Question

I have a quiz.我有一个测验。 I have 2 pages, I create the questions and their answers on the first page and I put these questions on the second page, but I want these questions to have the Answer model input, ie each question has its own input.我有 2 页，我在第一页创建问题及其答案，并将这些问题放在第二页，但我希望这些问题有 Answer model 输入，即每个问题都有自己的输入。 When I try to set a query with an Id in the view and the unsuitable Answer form to save does not work, it is not stored in the database.当我尝试在视图中设置带有 Id 的查询并且不适合保存的答案表单不起作用时，它不会存储在数据库中。 How do I save?我该如何保存？

models.py模型.py

from django.db import models

# Create your models here.
class Question(models.Model):
    question=models.CharField(max_length=100)
    answer_question=models.CharField(max_length=100, default=None)

    def __str__(self):
        return self.question

    
class Answer(models.Model):
    questin=models.ForeignKey(Question, on_delete=models.CASCADE, related_name="questions")
    answer=models.CharField(max_length=100,blank=True)

    def __str__(self):
        return str(self.questin)

forms.py forms.py

from django import forms

class QuestionForm(forms.ModelForm):
    class Meta:
        model=Question
        fields="__all__"


class AnswerForm(forms.ModelForm):
    class Meta:
        model=Answer
        fields="__all__"
