edikud提到希望增加随机文章的功能，其实这个与增加热门文章类似，也是修改model.py文件，Blog类，就在上次的hotposts函数下面，增加下面一段代码（那个num=3是说每次取3个随机文章）

def randposts(self, num = 5):
entries = Entry.all().filter('entrytype =', 'post').filter('published =', True)
#TODO use entry_num since already got the entries from db
if not entries or num >= g_blog.entrycount:
return entries
rand_ids = {}
for i in range(0, num):
rand = random.randint(0, g_blog.entrycount - 1)
#hope the entrycount in the blog is big a lot then num
while rand_ids.has_key(rand):
rand = random.randint(0, g_blog.entrycount - 1)
rand_ids.update({rand:True})

result = []
for id in rand_ids.keys():
result.append(entries.fetch(1, offset = id)[0])

return result

加好后，就修改模板文件sidebar.html，拷贝原来的热门文章的那一段就可以啦，只需要把其中的hotposts修改为randposts

---------------------------------------------------------------

使用micolog的过程中，发现blog记录的发表文章总数在某些情况下可能产生问题。这个数只增不减，并且有可能增加到超过实际的文章总数，使分页时候产生的最末几页没有文章。

下面所提要增加的代码，均为这两行代码，其实应该将这个层次抽象的更好的，但徐大的代码已经写成这样了，这代码风格，实在不敢恭维啊

g_blog.entrycount –= 1

g_blog.save()

1.文章删除后，没有对文章计数进行减少。修改admin.py中admin_enties类，post函数，在那个for循环里面，与entry.delete()左对齐，增加那两行代码（其实可以将第二行放在for外面优化一下）

2.在admin后台，将已存在的文章状态修改为非publish，没有对entrycount进行减少。修改admin.py中admin_entry类，post函数，大约590行的位置（改过不少，不知道具体在哪了），或者说就是那个if published的else分支最后，加上那两行代码

3.通过live writer将一个已经发表的文章修改为不发表时，没有对entrycount进行减少。修改api_rpc.py中metaWeblog_editPost函数，在最后的return上面，就是那个if publish的else分支，增加那两行代码

4.通过live writer删除文章时没有对entrycount进行减少。修改api_rpc.py中blogger_deletePost函数，在函数的最后（return那一行）加上那两行代码

通过修改上面五处，可以在一定程度上减少分页错误的问题。嗯，我说的就是一定程度上，因为page也是算做文章的一种，同时这个东东也参与到了对已发表文章的计数中。要想解决这个问题，需要做如下修改：

在model.py的Entry类，publish函数中，if newval的判断中的那个”if not self.published:”修改为”if (not published) and (self.entrytype == ‘post’):”

顺便说上一句，Entry的那个publish函数，newval为False的分支从来没有走到过，并且，那个分支的代码是有错误的…，不知道这个newval是做什么用的

micolog的页码输出，第一页是从零开始的，真是很奇怪，简单修改一下，从1开始吧，代码修改如下（blog.py文件MainPage类），注意红色部分是修改的内容,(为了节省篇幅，没修改过的地方省略)

class MainPage(BasePublicPage):

def get(self,page=1):

…

@cache()
def doget(self,page):

max_page = -(self.blog.entrycount / -self.blog.posts_per_page)

…

if page < 1 or page > max_page:
return    self.error(404)

logging.debug(“MainPage doget fetching entries”)
entries = Entry.all().filter(‘entrytype =’,'post’).\
filter(“published =”, True).order(‘-date’).\
fetch(self.blog.posts_per_page, offset = (page – 1) * self.blog.posts_per_page)

for entry in entries:
addReadTime(entry)

show_prev = entries and  (not (page == 1))
show_next = entries and  (not (page == max_page))

晚上回家，的dev上搞代码，发现清了数据必然出现一次NoneType的get_theme问题。原因是InitBlogData函数没有返回g_blog，导致在get_theme的时候必然是None。当然，再刷新一下浏览器就好了。当然，这个对已经用上micolog的我们几乎没啥影响，不过为了追求完美，在entry.publish()下面还是要加上一句 return g_blog

def InitBlogData():
import settings
global g_blog
g_blog = Blog(key_name = ‘default’)
g_blog.domain=os.environ['HTTP_HOST']
g_blog.baseurl=”http://”+g_blog.domain
g_blog.feedurl=g_blog.baseurl+”/feed”
g_blog.language=settings.LANGUAGE_CODE
g_blog.save()
entry=Entry(title=(“Hello world!”).decode(‘utf8′))
entry.content=(‘

Welcome to micolog. This is your first post. Edit or delete it, then start blogging!

‘).decode(‘utf8′)
entry.publish()

 

def gblog_init():
logging.info(‘module setting reloaded’)
global g_blog

g_blog = Blog.get_by_key_name(‘default’)
if not g_blog:
g_blog=InitBlogData()

g_blog.get_theme()

g_blog.rootdir=os.path.dirname(__file__)

logging.info(g_blog.rootdir)

好久没有搞micolog的代码了，看到大家已经更新了很多功能，我也抽时间改一下，这次主要的改动有

1.主题inove，就是WordPress的那个经典主题

2.增加qq表情评论功能

3.增加品论的引用功能

最近好多童鞋发邮件问部署的问题（大多数人是index.yaml的修改问题），还有童鞋发邮件要我修改过的micolog的代码。在这里提供个我修改过的index.yaml吧，并且附上我修改过的micolog的下载地址。

我改过的主要内容，请查看这个blog的micolog目录中的那些文章

index.yaml,如果你用徐老大的0.5版本，可以使用这个index.yaml(与从我这里下载的micolog是不同的，因为我修改的版本里面增加了readtime，为了不出错，这里面的index.yaml的readtime删掉了)

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
# automatically uploaded to the admin console when you next deploy
# your application using appcfg.py.
