Dynamic variables in map function couch db

Question

I am now using couchdb as my database , how to use dynamic variables as parameters in map functions in couch db?

Answer 1

The map-component of views in couchdb are defined by you and included in the design doc. Then these functions can be reached through http://localhost:5984/yourDatabase/_design/doc/_view/yourViewFunction

The dynamic variables you might be looking for is passing a query with the url like this

http://localhost:5984/yourDatabase/_design/doc/_view/yourViewFunction?key=value-pairs-stacked-with-&(ampersand)

Then you can pass the _view/function startkey, endkey and a few others. Please have a read here for further studies.

Hope my answer made sense =) Good luck!

Answer 2

You can't pass parameters to views in CouchDb. The views in many cases have already been built. You'll need to structure your views to handle the queries that you'll need.
