Micolog的小小错误！（一个Google上的博客程序）

2009年05月07日 07:57

在Micolog的论坛中很多人提到这个错误。

就是安装完，该博客后访问首页出现下面的错误：

A server error occurred. Please contact the administrator.

不直接执行update.bat,而是在命令行的上一级目录中手动执行appcfg.py update micolog,你会看到如下错误：

Scanning files on local disk.

-stream.

Error 400: --- begin server output ---
Creating a composite index failed: This index:
entity_type: "Archive"
ancestor: false
Property {
name: "date"
direction: 2
}

is not necessary, since single-property indices are built in. Please remove it f
rom your index file and upgrade to the latest version of the SDK, if you haven't
already.
--- end server output ---
Your app was updated, but there was an error updating your indexes. Please retry
later with appcfg.py update_indexes.

很明显，这个是索引的问题，原因是仅仅对单个字段进行索引是不需要的。可能早期这种模式是支持的。

按照下面来修改就OK了。吧不要的注释掉：

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.
