swag-mvc

connecting your models and routes in node.js

Creating

• var mvc = require('mvc')( app ) Pass in express.createServer()

Models

• mvc.initModels( models, dir, setupFunction, args ) sets up models in dir defined in the array of strings models. setupFunction has two arguments, one is the capitalized name of the model and the other is the return value of the model file in dir/ModelName to hook it into your database of choice. args are arguments passed into the model file.

Routes

• mvc.initRoutes( routes, dir, args ) sets up the routes in dir, defined with an array of strings routes, passing in app, corresponding model if applicable, followed by additional args.

Example

app.js

  mvc = require('mvc')( app );
  db  = mongoose.connect( url );
 
  mvc.initModels( [ 'User' ], __dirname + '/models/', function ( name, schema ) {
    db.model( name, schema );
    return db.model( name );
  }, {
    mongoose: mongoose
  });
 
  mvc.initRoutes( [ 'users', 'pages', 'sesions' ], __dirname + '/controllers/', {
    auth: function ( req, res, next ) {
      req.isAuthenticated() ? next() : res.redirect( '/login' );
    });
  });

ROOT/controllers/users.js

  // Passing in arguments app, the model, and arguments object passed in
  // during initRoutes
  module.exports = function ( app, User, args ) {
    app.get( '/users', function ( req, res, next ) {
      User.find( {}, ( err, users ) {
        if ( !err ) { res.render( 'users/index', { users: users } }
      });
    });
 
    app.get( '/register', function ( req, res, next ) {
      res.render( '/users/new' );
    });
  };

ROOT/models/User.js

  module.exports = function ( args ) {
    mongoose = args.mongoose;
    ObjectId = mongoose.SchemaTypes.ObjectId;
 
    UserSchema = new mongooose.Schema({});
 
    // this is the schema passed into the
    // setupFunction in initModels
    return UserSchema;
  };
