sails v10.0 on mysql encountering 'schema' of undefined

问题

i'm trying out sails js version 0.10.0 with sails-mysql adapter 0.10.6

I created two models:

Customer.js

module.exports = {

  connection: 'someMysqlServer',

  attributes: {
    name: {
        type: 'string'
    },

    store: {
        model: 'Store'
    }
  }
};

and Store.js

module.exports = {

  connection: 'someMysqlServer',

  attributes: {
    name: {
        type: 'string'
    },

    customers: {
        model: 'Customer',
        required: false
    }
  }
};

when I first run the application, all is fine and I can see that it created two tables on my database. However, when I try to restart the application I am getting this error:

TypeError: Cannot read property 'schema' of undefined

    at Socket.<anonymous> (C:\fray\NodeJs\testingsails10_2\test1001\node_modules
\sails-mysql\node_modules\mysql\lib\Connection.js:75:28)

and if I drop the tables and restart the application, it'll be able to run and re-create the table, but won't go further, when I get to this controller.

module.exports = {
    add: function(req, res){
        var store = {
            name: 'strore2'
        }
        Store.create(store).exec(function(err, result){
            Customer.create({name: 'customer1', store: result.id}).exec(function (err1, result1){
                return res.json({created: result1, error: err1});   
            });
        });

    }

};

and will throw this error:

回答1:

This seems like a broken dependencies issue. Try:

rm -rf node_modules
npm cache clear
npm install

To reinstall all the dependencies, then try sails lift.

At this point you will have Sails installed locally in your project, and sails lift will use that copy. To perform a similar surgery on your global sails install, do:

sudo npm uninstall -g sails
npm cache clear
sudo npm install -g sails

Then rm -rf node_modules/sails in your project so that sails lift will use the global install.
