cdbAddAttachment {R4CouchDB}

Add attachments

Description

This function adds attachments to a database document that already exists.

Usage

cdbAddAttachment(cdb)

Arguments

cdb

The list cdb has to contain cdb$fileName,cdb$serverName, cdb$DBName and a cdb$id.

Details

The function uses the RCurl- function guessMIMEType() to do exactly this: guessing the mime type of cdb$fileName.

If the switch cdb$attachmentsWithPath is set to TRUE the attachment is saved with the path. This behavior is default since version 0.2.5 of R4CouchDB

Value

cdb

The result is stored in cdb$res
