python - 为什么我的 ModelChoiceField 显示三个表单而不是两个表单，为什么它不读取我的选择？

问题描述

首先，我将两个模型表单融合到一个表单中，它们应该显示主题名称和问题类型，但由于某种原因，出现了三个表单，第一个没有显示第二个出现的选项两次，我不希望第二次出现，因为我的 CSS 没有应用在它上面。

选择没有出现。
三种形式而不是两种形式。

这是我的model.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_description

class Answer(models.Model):
    answer_description = models.TextField()
    answer_image = models.ForeignKey(    'Image',
                                    on_delete=models.CASCADE,
                                    blank=True,
                                    null=True)

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

这是我的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.ModelChoiceField(
                    queryset = Topic.objects.all(),
                    widget = forms.Select(
                    choices=(question_topic_name_choices),
                    attrs = {'class': 'home-select-one'}
                    ))
    class Meta:
        model = Topic
        fields = ['topic_name',]

class QuestionForm(forms.ModelForm):
    question_type =   forms.ModelChoiceField(
                    queryset = Topic.objects.all(),
                    widget = forms.Select(
                    choices=(questions_type_choices),
                    attrs = {'class': 'home-select-two'}
                    ))
    class Meta:
        model = Question
        fields = ['questions_type',]
class QuizMultiForm(MultiModelForm):
    form_classes    =   {
                'topics':TopicForm,
                'questions':QuestionForm
    }
    def save(self, commit=True):
        objects = super(QuizMultiForm, self).save(commit=False)

        if commit:
            topic_name = objects['topic_name']
            topic_name.save()
            question_type = objects['question_type']
            question_type.topic_name = topic_name
            question_type.save()
        return objects

这是我的views.py

    from django.shortcuts import render, render_to_response
    from django.views.generic import CreateView
    from home.models import Topic, Image, Question, Answer
    from home.forms import QuizMultiForm



    def QuizView(request):
        if request.method == "POST":
            form = QuizMultiForm(request.POST)
            if form.is_valid():
                pass
        else:
            form = QuizMultiForm()
        return render(request, "index.html", {'form': form})

这是choices.py

question_topic_name_choices = (
    (1, ("Topic #1: Measurements and Uncertainties")),
    (2, ("Topic #2: Mechanics")),
    (3, ("Topic #3: Thermal Physics")),
    (4, ("Topic #4: Waves")),
    (5, ("Topic #5: Electricity and Magnetism")),
    (6, ("Topic #6: Circular Motion and Gravitation")),
    (7, ("Topic #7: Atomic, Nuclear and Particle Physics")),
    (8, ("Topic #8: Energy Production")),
    (9, ("Topic #9: Wave Phenomena (HL Only)")),
    (10, ("Topic #10: Fields (HL Only)")),
    (11, ("Topic #11: Electromagnetic Induction (HL Only)")),
    (12, ("Topic #12: Quantum and Nuclear Physics (HL Only)")),
    (13, ("Option A: Relativity")),
    (14, ("Option B: Engineering Physics")),
    (15, ("Option C: Imaging")),
    (16, ("Option D: Astrophysics"))
        )

questions_type_choices = (
    (1, ("Multiple Choice Questions")),
    (2, ("Problem Solving Questions")))

这是模板

{% 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>
        </form>
    {% endblock content %}

谢谢你的帮助！
