Question

我正在尝试创建一个简单的django应用程序，该应用程序将在主页面上显示论坛列表，以及当用户点击论坛标题以获取属于该论坛的帖子时

这里是帖子模型的代码：

class Post(models.Model):
author = models.ForeignKey('auth.User')
title = models.CharField(max_length=200)
text = models.TextField()
created_date = models.DateTimeField(
    default=timezone.now)
published_date = models.DateTimeField(
    blank=True, null=True)
forum = models.ForeignKey('Forum') # referinta la Forum
upload = models.FileField("Upload a file", upload_to = 'media', null=True, blank=True)

def publish(self):
    self.published_date = timezone.now()
    self.save()
def __str__(self):
    return self.title

论坛模型的代码：

class Forum(models.Model):
    title = models.CharField(max_length=200)
    published_date = models.DateTimeField(blank=True, null=True)

    def __str__(self):
        return self.title

views.py中的代码：

def forum_list(request):
forums= Forum.objects.filter(published_date__lte=timezone.now()).order_by('published_date')
return render(request, 'students_platform/post_list.html', {'forums': forums})

def post_list(request):
     posts=Post.objects.filter(published_date__lte=timezone.now()).order_by('published_date')
return render(request, 'students_platform/post_list.html', {'posts': posts})

最后，我有一个post_list.html文件，如下所示：

<html>
<head>
    <title>Informatii despre examene</title>
</head>
<body>
    <div>
        <h1> Informatii despre examene</h1>

    <h2> Bine ati venit! </h2>
    </div>
{% for forum in forums %}
<div>


    <h1><a href="">{{ forum.title }}</a></h1>
    <p>{{ forum.text|linebreaks }}</p>

</div>
{% endfor %}

</body>
</html>

如何编辑html文件，以便每次点击论坛标题将我带到添加到该论坛的帖子？

添加到您的PostModelAdmin list_filter = ('forum',)

https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_filter

<a href="{% url 'admin:yourappname_post_changelist' %}?forum__id__exact={{ forum.id }}">{{ forum.title }}</a>
