Unable to access a record of a collection of mongo using monk in node.js

Question

I am trying to access the data returned by the find method in monk using:

var collection = db.get('Workflow');
collection.find({},{},function(e,workflow){
    console.log(workflow);
    var req0 = workflow[0];  //Error here
    console.log(req0);
    console.log(req0, req.body.accountType);
});

The first console.log(workflow) returns me the whole record correctly which looks like a json array. However, when I am trying to access, it gives me the following error:

TypeError: Cannot read property '0' of undefined

Answer 1

Because, it doesn't return array. If you only require the first record, why not try the 'limit'

var collection = db.get('Workflow');
collection.find({},{'limit':1},function(e,workflow){
    console.log(workflow);
    var req0 = workflow;
    console.log(req0);
});
