在models.py文件中，我有两个类：问答。在views.py文件中，我使用的是django.views.generic中的现成类表单。那么如何在detailview HTML中显示问题答案呢

models.py文件

from django.db import models
from django.conf import settings
from django.utils import timezone
from django.urls import reverse
from django.contrib.auth.models import User

class Question(models.Model):
    author  = models.ForeignKey(User, on_delete=models.CASCADE)
    title   = models.CharField('Title', max_length=70)
    content = models.TextField('Body', null=True, blank=True)
    date    = models.DateTimeField(default=timezone.now)

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('current', kwargs={'pk': self.pk})

    class Meta:
        verbose_name_plural = 'Questions'
        verbose_name        = 'Question'

class Answer(models.Model):
    author   = models.ForeignKey(User, on_delete=models.CASCADE)
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    content  = models.TextField('Body', null=True, blank=True)
    date     = models.DateTimeField(default=timezone.now)

    def __str__(self):
        return self.content

    class Meta:
        verbose_name_plural = 'Answers'
        verbose_name        = 'Answer'

views.py

from django.shortcuts import render
from django.contrib.auth.mixins import LoginRequiredMixin, UserPassesTestMixin
from .models import Question, Answer
from django.shortcuts import redirect
from django.views.generic import (
    ListView,
    DetailView,
    CreateView,
    UpdateView,
    DeleteView
)

def index(request):
    context = {
        'questions': Question.objects.all()
    }

    return render(request, 'f/index.html', context)

class QuestionListView(ListView):
    model = Question
    template_name = 'f/index.html'
    context_object_name = 'questions'
    ordering = ['-date']

class QuestionDetailView(DetailView):
    model   = Question
    answers = Answer

class QuestionCreateView(LoginRequiredMixin, CreateView):
    model  = Question
    fields = ['title', 'content']
    
    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)

问题_detail.html 在这个文件中是每个问题的详细信息

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>{{ object.title }} - :) </title>
</head>
<body>
    <img class="circle-img" src="{{ object.author.profile.image.url }}">
    <p class="question-title">{{ object.title }}</p>
    <p class="question-body">{{ object.content }}</p>
    <p class="post-date">{{ object.date|date:"F d, Y" }}</p>
    
    {% if object.author == user %}
        <div>
        <a class="btn btn-secondary btn-sm mt-1 mb-1" href="{% url 'question-update' object.id %}">Update</a>
        <a class="btn btn-danger btn-sm mt-1 mb-1" href="{% url 'question-delete' object.id %}">Delete</a>
        </div>
        <script>
            console.log('You are the author of this question :3');
        </script>
    {% endif %}
</body>
</html>


{{object.title}}-：）
{{object.title}
{{object.content}
{{object.date | date:“fd，Y”}
{%if object.author==user%}
log（“您是这个问题的作者：3”）；
{%endif%}

我已经在管理页面中创建了问题的答案

您可以使用它从

问题

实例获取

答案

对象。像这样：

# template: question_detail.html

{% for answer in object.answer_set.all %}
     {{ answer.content }}
     {{ answer.author }}
{% endfor %}

是的，谢谢，但是如何在views.py中查看QuestionDetailView？您只需要从该视图中删除

answers=Answer

。这部分代码在那里没有任何功能。
