我正在使用本教程http://lightbird.net/dbe/blog.html创建一个简单的博客。我是 django 新手,按照本教程中的一些步骤操作时遇到问题。我尽力去理解,有时我就是不明白。我尝试获取源代码,但文件已损坏。
我需要解释的步骤是:
发布页面
对于每个帖子,我们还需要一个单独的页面,其中包含访问者的评论和完整的帖子文本(如果我们稍后决定限制在首页上显示帖子正文)。这是我计划设置的方式: url 将是
/blog/post/{pk}/
postpk
对象的主键;模板将被调用post.html
,视图函数将是post()
.主列表将显示一个简单的链接:
<div class="commentlink"> <a href="{% url blog.views.post post.pk %}">Comments</a> </div>
如果这不是一个合适的问题,我很抱歉。
我已经到了发布页面的步骤,我只是不知道该怎么做!
