Question

我花了好几个小时做这件事。

我有一个类别页面，如果我点击一个特定的页面，那么该页面内的帖子列表会导致单个帖子页面。

单个帖子页面正常工作，单个类别页面正常工作，但是类别页面内的页面无效，这有意义吗？

def post(request, slug):#this is my view
    single_post = get_object_or_404(Post, slug=slug)
    single_post.views += 1  # increment the number of views
    single_post.save()      # and save it
    t = loader.get_template('main/post.html')
    context_dict = {
        'single_post': single_post,
    }
    c = Context(context_dict)
    return HttpResponse(t.render(c))

def category(request, category_name_slug):
    context_dict = {}
    try:
        category = Category.objects.get(slug=category_name_slug)
        context_dict['category_name'] = category.name

        posts = Post.objects.filter(category=category)
        context_dict['posts'] = posts
        context_dict['category'] = category
    except Category.DoesNotExist:
        pass

    return render(request, 'main/category.html', context_dict)


this is my url
urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^(?P<slug>[\w|\-]+)/$', views.post, name='post'),
    url(r'^category/(?P<category_name_slug>[\w\-]+)/$', views.category, name='category')

]

这是我的类别html

{% extends 'base.html' %}

{% block content %}
<h1>{{category_name}}</h1>
{% if category %}
    {%if posts %}
    <ul>
        {% for post in posts %}
        <h3><a href="{{ post.slug }}">{{ post.title }}</a></h3>

        {% endfor %}
    </ul>
    {%else%}
        <strong>No Pages </strong>
    {% endif %}
{% else %}
{{category_name}} does not exist
{% endif %}

{% endblock %}

最后post.html

<html>
    <head>
        <title></title>
    <head>

    <body>
        <h2>{{single_post.title}}</h2>
        <p>{{single_post.content}}</p>
        <p> Views: {{single_post.views}}
            <br>
            <p>
                {% if single_post.image %}
                <img src="/media/{{single_post.image}}">
            {% endif %}
            </p>
<body>

它给了我404错误，有趣的是url给我的错误是127.0.0.1:8000/category/hello/adele但127.0.0.1:8000/adele不给我错误。所以在类别页面内，我想访问127.0.0.1:8000/adele -

Answer 1

将<a href="{{ post.slug }}">{{ post.title }}</a>替换为<a href="/{{ post.slug }}">{{ post.title }}</a>

问题是如果锚中的引用不是以/开头，则表示它是一个相对URL，并且该引用被添加到当前url。希望这对你有所帮助。如需进一步参考，请使用django的absolute_url功能。请阅读this：）

Answer 2

使用url模板标记：

convert_0_1_2 :: State (a, b) x -> State (a, b, c) x
convert_0_1_2 f = do
    (a, b, c) <- get
    let (x, (a', b')) = runState f (a, b)
    put (a', b', c)
    return x

convert_0_2_1_0 :: State (c, b) x -> State (a, b, c, d) x
convert_0_2_1_0 f = do
    (a, b, c, d) <- get
    let (x, (b', c')) = runState f (b, c)
    put (a, b', c', d)
    return x

根据您的网址配置重建网址，确保它是有效的网址。这里，{% for post in posts %} <h3><a href="{% url 'post' slug=post.slug %}">{{ post.title }}</a></h3> {% endfor %}是您在urlconf中定义的网址的名称，'post'是您传递给网址正则表达式中的捕获组的参数。

在django中连接URL
