问题描述

推荐答案

读取，修改和保存文档的代码为:

The code for reading, modifying and then saving a document is:

Document doc = db.getDocument("documentid1234");
doc.put("foo","bar");
db.saveDocument(doc);

doc对象将包含通过getDocument()调用读取文档后的_rev.

The doc object will contain the _rev from when the document was read with the getDocument() call.

您不生成_rev值，而是沙发生成.

You don't generate the _rev value, couch does.
