Querying Couchbase view by passing parameter

Question

I have Couchbase notification documents stored in below format:

{
    "_id":"notification::5403cb1a6c965dcfe9",
    "alert":"test data",
    "body":{
        "created_by":"user_54986e326694f10e511cf",
        "description":" reported ",

    },
    "channels":[
        "user_54986e326694f10e511cf",
        "user_54986e326694f10e511cp"
    ],
    "notification_type":"new_report",
    "seen":true,
    "timestamp":"2015-01-06T15:48:25.092Z",
    "type":"notification"
}

The JSON document contains channels array, it is a list of user_id who subscribe to channels. Problem is I have to emit notification document if chaneel field contain user_id, if I pass user_id ='user_54986e326694f10e511cf' pass as key parameter.

Below is my Couchbase view map function but it doesn't return anything

function (doc, meta) {
  if(doc.type=='notification' && doc.channels){

        for (var user in doc.channels) {
            emit(user, {
                alert: doc.alert,
                body: doc.body,
                seen: doc.seen,
                timestamp: doc.timestamp
            });

        }

    }
}

I am wondering where i am doing wrong.

Those "alert", "body", "seen" etc that you're emitting as keys in the dictionary - are those strings? if so, shouldn't they be quoted?

In other words, try this:

function (doc, meta) {
    if(doc.type=='notification' && doc.channels){

        for (var user in doc.channels) {
            emit(user, {
                "alert": doc.alert,
                "body": doc.body,
                "seen": doc.seen,
                "timestamp": doc.timestamp
            });
        }
    }
}
