Я хочу получить question_description answer_descritption и question_image answer_image, если они найдены в базе данных в соответствии с темой и типом вопроса, используя два ChoiceField для обоих: Тема и Тип вопроса.
Однако я не знаю, как это сделать.Я видел некоторые учебные пособия и получил представление о том, что мне нужно делать, но я не уверен, как выполнить те же приемы в моем случае, потому что в Интернете не так много ChoiceField примеров, за исключением того, что есть общие примеры того, какиспользуйте формы и извлекайте данные из базы данных.
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):
question_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_description = models.TextField()
answer_image = models.ForeignKey( 'Image',
on_delete=models.CASCADE,
blank=True,
null=True)
answer_topic = models.ForeignKey( 'Topic',
on_delete=models.CASCADE,
blank=True,
null=True)
def __str__(self):
return '%s' % self.answer_description
Это forms.py
from django import forms
from betterforms.multiform import MultiModelForm
from .models import Topic, Image, Question, Answer
from .choices import questions_type_choices, question_topic_name_choices
class TopicForm(forms.ModelForm):
topic_name = forms.ChoiceField(
choices=question_topic_name_choices,
widget = forms.Select(
attrs = {'class': 'home-select-one'}
))
class Meta:
model = Topic
fields = ['topic_name',]
def __str__(self):
return self.fields
class QuestionForm(forms.ModelForm):
question_type = forms.ChoiceField(
choices= questions_type_choices,
widget = forms.Select(
attrs = {'class': 'home-select-two'},
))
class Meta:
model = Question
fields = ['question_type',]
def __str__(self):
return self.fields
class QuizMultiForm(MultiModelForm):
form_classes = {
'topics':TopicForm,
'questions':QuestionForm
}
Это views.py
from django.shortcuts import render, render_to_response
from django.views.generic import TemplateView
from home.models import Topic, Image, Question, Answer
from home.forms import QuizMultiForm
class QuizView(TemplateView):
template_name = 'index.html'
def get(self, request):
# What queries do I need to put here to get the question and answer's description according to the ChoiceField input
form = QuizMultiForm()
return render (request, self.template_name, {'form': form})
def post(self, request):
form = QuizMultiForm(request.POST)
if form.is_valid():
text = form.cleaned_data['topic_name', 'question_type'] # I don't know what to put here!
args = {'form': form, 'text': text}
return render (request, self.template_name, args)
Это шаблон:
{% extends 'base.html' %}
{% block content %}
<form method="POST">
{% csrf_token %}
{{ form.as_p }}
<button type="submit" id="home-Physics-time-button">It is Physics Time</button>
<h1> {{ text }} </h1>
</form>
{% endblock content %}
Я бы хотел помочь!Спасибо!
