给micolog增加最热最冷文章排行及评论排行
１.打开model.py,在class Blog(db.Model):最后添加如下代码（红色部分）数字代表显示列表数目
|
def recentposts(self):
return Entry.all().filter('entrytype =','post').order('-date').fetch(8) def hotposts(self):
return Entry.all().filter('entrytype =','post').filter("published =", True).order('-readtimes').fetch(8) def coldposts(self):
return Entry.all().filter('entrytype =','post').order('readtimes').fetch(8)
|
2.在sidebar.html中添加 我的如下：
|
<div class="block">
<h2>热门文章</h2>
<ul>
{% for entry in blog.hotposts %}
<li><a href="/{{entry.link}}">{{entry.title}}</a> ({{entry.readtimes}})</li>
{%endfor%}
</ul>
</div> <div class="block">
<h2>冷门文章</h2>
<ul>
{% for entry in blog.coldposts %}
<li><a href="/{{entry.link}}">{{entry.title}}</a> ({{entry.readtimes}})</li>
{%endfor%}
</ul>
</div> |
在本地测试成功再上传到GAE！
另外，如果要添加热门评论可以在步骤1代码后面加入如下代码
def hotcommentposts(self):
return Entry.all().filter('entrytype =','post').order('-commentcount').fetch(8)

你看我的首页用IE访问进入分类，字体变大时怎么回事啊？还有那个顶部的菜单，鼠标效果为何是一半黑的一半白的。用GOOGLE浏览器访问就没有这问题。
还以为你的是wp呢。。。
看来micolog也不错
用了你的model.py也不行？
@edikud
你要的是什么功能，如果是本文的功能，还需在主题文件里修改
那还要加上什么啊!我试了几次了都不行!

哦 忘了你要什么功能了 是本文的所写的那个功能吗？
如果你用了我的model文件，再看文章的第2步
@houkai
是本文的所写的那个功能....
文章的第2步,我加上就是不行？没有加就没事。。

索引有问题 删除索引重新生成以下 试试

文章的第2步,我加上上传出现上面的错误。 删除索引重新生成也不行。。。

注意代码的缩进。另外你可以删除索引。或者用下面的索引试试
-------------------------------------------
indexes:
# AUTOGENERATED
# This index.yaml is automatically updated whenever the dev_appserver
# detects that a new type of query is run. If you want to manage the
# index.yaml file manually, remove the above marker line (the line
# saying "# AUTOGENERATED"). If you want to manage some indexes
# manually, move them above the marker line. The index.yaml file is

# your application using appcfg.py.

@houkai
还是不行啊，如果可能的话，能提供你使用的网站源码吗。
好像只要第一步出现代码里面出现readtimes后，调用就会出错。
@iandmmo
知道了 你要先给Micolog添加阅读次数 见www.houkai.com/?p=5003
我改了以后提示缩进错误，真麻烦呀。
感谢HOUKAI，第二次测试成功。开启Notepad++视图里的“显示空格和制表符”真的很有用！
