The following page has been changed by PaulDavis: http://wiki.apache.org/couchdb/Formatting_with_Show_and_List The comment on the change is: Redirect example ------------------------------------------------------------------------------ } }}} + + == Other Fun Things == + + === Stopping iteration in a `_list` === + + If you want to terminate iteration of a `_list` early you can return a `{stop: true}` JSON object from any of the calls to the function that include a row object. + + === Sending a Redirect === + + In the call to `_show` or when `_list` is called with a head object you can control the headers and status code sent to the client. An example of this would be to send a redirect notification. + + {{{ + function(doc) + { + return {"code": 302, "body": "See other", "headers": {"Location": "/"}}; + } + }}} + + {{{ + function(head, row, req, row_info) { + if (head) { + return {"code": 302, "body": "See other", "headers": {"Location": "/"}}; + } else if (row) { + return {stop: true}; + } else { + return "." + } + } + }}} + Hopefully this is enough to get started. For a more complete set of examples, see the CouchDB test suite, especially show_documents.js and list_views.js
