node.js - Document update error while inserting views dynamically in cloudant couchdb -

i using nosql database(cloudant-couchdb) first time , has been going far. stuck these 2 problems:

1. i trying add views dynamically. able add first view, errors while trying insert more views stating document update conflict. how 'update' since inserting new view everytime , not updating it?

2. is possible pass parameter in map function? - if(doc.name == somevariable)?

here code below:

app.put("/listsections", function(req, res) {     var module = req.body.name;     var obj = {};     obj[module] = { "map": function (doc) {         if (doc.name == "developer") {             //emit         }     } }); db.insert({views: obj},      '_design/section', function (error, response) {         if (error) {             console.log("error: " + error);         }         console.log("module: " + module );     } ); 

my approach wrong. found creating multiple views bad practice. created 1 (general) view, , passed queries parameters answer second question (how pass dynamic parameters). here did:

app.get("/listsections", function(req, res) {     var moduleid = req.query.id;     db.view('section','getsections', { key: moduleid }, function(err, body)    {        //store values    } } 

here pass moduleid dynamically map function sets key moduleid. also, found link pretty useful couchdb queries - http://sitr.us/2009/06/30/database-queries-the-couchdb-way.html
