在 django 管理数据库中，我没有得到预期的视图。我正在按照教程在 Django 中制作一个测验应用程序。我完全按照视频中所示做了，但我仍然没有得到相同的输出。我附上了预期视图的图片和我得到的图片。

得到这个： 在此处输入图像描述

期待这个： 在此处输入图像描述

models.py（在测验中）：

from django.db import models

from django.contrib.auth import get_user_model
User = get_user_model()

# Create your models here.
class Quiz(models.Model):
    name = models.CharField(max_length=255)
    description = models.CharField(max_length=70)
    slug = models.SlugField(blank=True)
    roll_out = models.BooleanField(default=False)
    timestamp = models.DateTimeField(auto_now_add=True)

    class Meta:
        ordering = ['timestamp',]
        verbose_name_plural = 'Quizzes'

    def __str__(self):
        return self.name


class Question(models.Model):
    quiz = models.ForeignKey(Quiz, on_delete=models.CASCADE, related_name='questions')
    label = models.CharField('Question', max_length=255)
    order = models.IntegerField(default=0)

    def __str__(self):
        return self.label

class Answer(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE, related_name='answers')
    label = models.CharField('Answer', max_length=255)
    is_correct = models.BooleanField('Correct answer', default=False)

    def __str__(self):
        return self.label

class QuizTaker(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    quiz = models.ForeignKey(Quiz, on_delete=models.CASCADE)
    score = models.IntegerField(default=0)
    completed = models.BooleanField(default=False)
    date_finished = models.DateTimeField()
    timestamp = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.user.username

class UserAnswer(models.Model):
    quiz_taker = models.ForeignKey(QuizTaker,on_delete=models.CASCADE)
    quistion = models.ForeignKey(Question,on_delete=models.CASCADE)
    answer = models.ForeignKey(Answer,on_delete=models.CASCADE)

    def __str__(self):
        return self.question.label

在 admin.py

from django.contrib import admin
import nested_admin
from .models import Quiz, Question, Answer, QuizTaker, UserAnswer

# Register your models here.

class AnswerInline(nested_admin.NestedTabularInline):
    model = Answer
    extra = 4
    max_num = 4

class QuestionInline(nested_admin.NestedTabularInline):
    model = Question
    inline = [AnswerInline]
    extra = 5

class QuizAdmin(nested_admin.NestedModelAdmin):
    inline = [QuestionInline,]

class UserAnswerInline(admin.TabularInline):
    model = UserAnswer

class QuizTakerAdmin(admin.ModelAdmin):
    inline = [UserAnswerInline,]

admin.site.register(Quiz,QuizAdmin)
admin.site.register(Question)
admin.site.register(Answer)
admin.site.register(QuizTaker,QuizTakerAdmin)
admin.site.register(UserAnswer)

在 settings.py
