Sails.js模型中的CRUD

Question

I have created a Sails.js Model by using command "sails generate model". The model is generated as follows:

module.exports = {
  connection: 'someMysqlServer',
  attributes: {
    amount : { type: 'float' },
    country : { type: 'string' },
    month : { type: 'string' }
  }
};

I am trying to use .create() function of an instance of this model , inside a controller as follow , but I receive error :

var myModel = require ('../models/Info') ;
module.exports = {
getInfo: function (req, res) {
      console.log("inside getInfo controller");
      myModel.create({amount:3.5 , country:'spain' , month: 'january' }) ;
  } ,
}

I receive the following error while using .create() function :

error: Sending 500 ("Server Error") response: 
 TypeError: Object #<Object> has no method 'create'

According to the following http://sailsjs.org/#/documentation/reference/waterline/models/create.html this method should be accessible automatically ?

Models are globalized for you by Sails; there is no need to attempt to require() them on your own nor will this work as intended.

If your model file lives in api/models/Info.js , then your controller would look something like:

module.exports = {
  getInfo: function (req, res) {
    Info.create({amount:3.5 , country:'spain' , month: 'january' });
  }
}

Rather than trying to follow the Waterline docs when creating a Sails app, you'll have a lot more luck following the Sails docs for models .
