本文介绍了使用CouchDB-Python获取文档级别的修订的完整列表吗?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我正在使用Sofadb-python( http://code.google.com/p/ ouchdb-python / ),我想知道是否有任何方法可以检索文档级别发生的修订的完整列表



<假设我有一个名为电影的数据库,它包含几个文档。
我的每个文档都有3个以上的修订版本。



我可以根据修订版本检索文档吗?



如果是,如何?我没有看到使用CouchDB-Python的任何明显方法

解决方案

我不确定沙发床Python,但是您可以通过HTTP API获取文档的整个已知修订历史记录。



CouchDB文档API 文档。



常规查询:

  $ curl jhs.couchone.com/db/doc 
{_id:'doc',
_rev:'3-825cb35de44c433bfb2df415563a19de'}

添加?revs = true 查看一系列旧修订。

  $ curl jhs.couchone.com/db/doc? revs = true 
{_id:'doc',
_rev:'3-825cb35de44c433bfb2df415563a19de',
_修订版:
{开头:3,
id:
['825cb35de44c433bfb2df415563a19de',
'7051cbe5c8faecd085a3fa619e6e6337',
'967a00dff5e02add41819138 abb3284d']}}

也可以添加?revs_info = true 获取有关修订的更多详细信息,例如它们是否仍然可用(即它们是在上一次压缩之后添加的,您可以提取它们。)

  $ curl jhs.couchone.com/db/doc? revs_info = true 
{_id:'doc',
_rev:'3-825cb35de44c433bfb2df415563a19de',
_revs_info:
[{rev:'3-825cb35de44c433bfb2df415563a19de',
状态:'available'},
{修订:'2-7051cbe5c8faecd085a3fa619e6e6337',
状态:'available'}},
{修订:'1-967a00dff5e02add41819138abb3284d',
状态: 'available'}]}


I was working couchdb-python ( http://code.google.com/p/couchdb-python/ ) and i was wondering if I have any way to retrieve a full list of revisions that have occurred on a document level?

Suppose I have a database named "movies" and it contains several documents. Each of my documents have more than 3 revisions.

Can I retrieve my documents based on the revisions?

If yes, how? I didn't see any obvious method to do it using CouchDB-Python

解决方案

I am not sure about couchdb-python, however you can get the entire known revision history of a document via the HTTP API.

Learn all about it in the CouchDB Document API documentation.

A normal query:

$ curl jhs.couchone.com/db/doc
{ _id: 'doc',
  _rev: '3-825cb35de44c433bfb2df415563a19de' }

Add ?revs=true to see an array of old revisions.

$ curl jhs.couchone.com/db/doc?revs=true
{ _id: 'doc',
  _rev: '3-825cb35de44c433bfb2df415563a19de',
  _revisions: 
   { start: 3,
     ids: 
      [ '825cb35de44c433bfb2df415563a19de',
        '7051cbe5c8faecd085a3fa619e6e6337',
        '967a00dff5e02add41819138abb3284d' ] } }

Also you can add ?revs_info=true for more details about the revisions, such as whether they are still available (i.e. they were added after the last compaction and you can fetch them).

$ curl jhs.couchone.com/db/doc?revs_info=true
{ _id: 'doc',
  _rev: '3-825cb35de44c433bfb2df415563a19de',
  _revs_info: 
   [ { rev: '3-825cb35de44c433bfb2df415563a19de',
       status: 'available' },
     { rev: '2-7051cbe5c8faecd085a3fa619e6e6337',
       status: 'available' },
     { rev: '1-967a00dff5e02add41819138abb3284d',
       status: 'available' } ] }
