Quick start

Get db collection


See mongoskin

var db = mongo.db("localhost:27017/?auto_reconnect=false",{
    database: 'test',
    safe: true
}, {
    connectArbiter: false,
    socketOptions: {
        timeout: 2000
    }
});

Single file require


// file path need full path
var path = require('path');
var mongolight = require('mongolight');
//db collection
mongolight.loadModel(path.join(__dirname,'./model/your_model.js'), {db: db});

Skip db parameter:

mongolight need the db collection to add some dynamic methods ,you can use the global to skip the db parameter.

var path = require('path');
// it will check global.db when you require a model
global._option.db = db ;
var mongolight = require('mongolight');
mongolight.loadModel(path.join(__dirname,'./model/your_model.js');

Multi-file require


if lazy loading is true , loadFolder method only set the path to global.

var path = require('path');
var mongolight = require('mongolight');
mongolight.loadFolder(path.join(__dirname,'./model'),{db:db,lazy:true});
//set the loadModel to global
global.loadModel = mongolight.loadModel;
/**
 *  when you use model class in first time,you need use loadModel method
 **/
//in index.js
loadModel('model');
module.exports = function(app){    
  app.get('/',function(req,res){
    var model = new Model();
    res.render('index', { title: 'Express' });
  });
};

when lazy loading is false,you can skip the loadModel method

var path = require('path');
var mongolight = require('mongolight');
mongolight.loadFolder(path.join(__dirname,'./model'),{db:db,lazy:false});

/**
 *  skip the loadModel method
 **/
//in index.js
module.exports = function(app){
  app.get('/',function(req,res){
    var model = new Model();
    res.render('index', { title: 'Express' });
  });
};

Default added methods

Model.findById(id,callback) :

   //use folder require
   loadModel('model');
   Model.findById('your_mongo_id',function(err,model)){
        if(err != null){
            throw err;
        }
        console.info(model);
   };

Model.findByOpt(opt,callback) :

    //use folder require
    loadModel('model');
    Model.findByOpt({key: 'search_content'},function(err,models){
        if(err != null){
            throw err;
        }
        console.info(models);
    });

Model.list(callback) :

the same method as Model.findByOpt({},callback):

    //use folder require
    loadModel('model');
    Model.list(function(err,models){
        if(err != null){
            throw err;
        }
        console.info(models);
    });

Model.modify(id,opt,callback) :

    //use folder require
    loadModel('model');
    Model.modify('mongo_id',{key: 'search_content'},function(err,result){
        if(err != null){
            throw err;
        }
        //updated record amounts
        console.info(result);
    });

Model.delById(id,callback) :

    //use folder require
    loadModel('model');
    Model.delById('mongo_id',function(err,result){
        if(err != null){
            throw err;
        }
        //deleted record amounts
        console.info(result);
    });

model.save(callback) :

save method will save the object to mongo.

     //use folder require
    loadModel('model');
    var model = new Model();
    model.save(function(err,model){
        if(err != null){
            throw err;
        }
        console.info(model);
    });
