customulize

Add arbitrary custom functions to sequelize models

Installation

npm install customulize

usage

var customulize = require('customulize');

var sequelizeCps = customulize('cps', function(model, method) {
    return function() {
        var newArgs = Array.prototype.slice.call(arguments),
            callback = newArgs.pop();
        model[method].apply(model, newArgs).complete(callback);
    };
});

// define your sequelize models
var models = {
    Account: require('./account')
};

// call function over them
sequelizeCps(models);

// now you can call methods via cps
models.Account.cps.find({ where: { id: 1} }, function(error, account) {
    if (error) {
        // error logic
    }
    account.name = 'John';
    account.cps.save(function(error, account) {

    });
});

kgo

customulize allows you to create a lazy calling pattern, eg:

var sequelazy = customulize('lazy', function(model, method) {
    return function() {
        var query = model[method].apply(model, arguments);
        return query.complete.bind(query);
    };
});

When using kgo this is especially convenient:

kgo
('account', Account.lazy.find({where: {id: 1}}))
('update', ['account'], function(account, done) {
    account.name = 'John';
    account.cps.save(done);
})
// etc, etc, etc
