У меня было несколько проблем при создании этого сайта, и это самый новый.Я создал эти поля выбора, однако, только цифры отображаются в первом, где во втором и потому что question_type связан с таблицей Question, вопросы, которые я добавляю в базу данных, показываютвверх вместо типа квестона, где есть только два типа вопросов, которые должны отображаться.И в зависимости от выбора, сделанного пользователем, новая страница, предназначенная только для чтения, будет отображаться с вопросами, относящимися к этой конкретной теме, с определенным типом вопросов.
Это models.py
from django.db import models
from home.choices import *
# Create your models here.
class Topic(models.Model):
topic_name = models.IntegerField(
choices = question_topic_name_choices, default = 1)
def __str__(self):
return '%s' % self.topic_name
class Image (models.Model):
image_file = models.ImageField()
def __str__(self):
return '%s' % self.image_file
class Question(models.Model):
questions_type = models. IntegerField(
choices = questions_type_choices, default = 1)
question_topic = models.ForeignKey( 'Topic',
on_delete=models.CASCADE,
blank=True,
null=True)
question_description = models.TextField()
question_answer = models.ForeignKey( 'Answer',
on_delete=models.CASCADE,
blank=True,
null=True)
question_image = models.ForeignKey( 'Image',
on_delete=models.CASCADE,
blank=True,
null=True)
def __str__(self):
return '%s' % self.question_type
class Answer(models.Model):

answer_image = models.ForeignKey( 'Image',
on_delete=models.CASCADE,

null=True)
def __str__(self):
return '%s' % self.answer_description

Это views.py
