Reading Data from the collection is very easy. Getting all data of the collection.

var Auto = require('models/auto')
Auto.find({}, function (err, autos) {
      if (err) return console.error(err);
       // will return a json array of all the documents in the collection
      console.log(autos); 
})

Reading data with a condition

Auto.find({countOf: {$gte: 5}}, function (err, autos) {
      if (err) return console.error(err);
       // will return a json array of all the documents in the collection whose count is greater than 5
      console.log(autos); 
})

You can also specify the second parameter as object of what all fields you need

Auto.find({},{name:1}, function (err, autos) {
      if (err) return console.error(err);
       // will return a json array of name field of all the documents in the collection
      console.log(autos); 
})

Finding one document in a collection.

Auto.findOne({name:"newName"}, function (err, auto) {
      if (err) return console.error(err);
     //will return the first object of the document whose name is "newName"
      console.log(auto); 
})

Finding one document in a collection by id .

Auto.findById(123, function (err, auto) {
      if (err) return console.error(err);
     //will return the first json object of the document whose id is 123
      console.log(auto); 
})
