使用couchdb-python进行多个CouchDB文档获取

Question

如何从CouchDB中获取多个文档,特别是使用couchdb-python？

Answer 1

最简单的方法是将include_docs = True arg传递给Database.view.结果的每一行都包含doc.例如

>>> db = couchdb.Database('http://localhost:5984/test')
>>> rows = db.view('_all_docs', keys=['docid1', 'docid2', 'missing'], include_docs=True)
>>> docs = [row.doc for row in rows]
>>> docs
[<Document 'docid1'@'...' {}>, <Document 'docid2'@'...' {}>, None]

请注意,如果文档不存在,则行的doc将为None.

这适用于任何视图 - 只提供适合视图的键列表.

Answer 2

import couchdb
import simplejson as json

resource = couchdb.client.Resource(None, 'http://localhost:5984/dbname/_all_docs')
params = {"include_docs":True}
content = json.dumps({"keys":[idstring1, idstring2, ...]})
headers = {"Content-Type":"application/json"}
resource.post(headers=headers, content=content, **params)
resource.post(headers=headers, content=content, **params)[1]['rows']
