usage
Basically you can inherit from this class, it will provides some basic methods & functions required for wrting an extension for the orm
var Class = require('ee-class')
, ORMExtension = require('ee-orm-extension');
var MyFancyORMExtension = new Class({
inherits: ORMExtension
// class constructor
, init: function(options) {
}
});
You can listen for events that are emitted by the model instances or the resource object (this is used for building select quieries). You can also inject methods into the models and the querbuilders prototype.
extending the model / querybuilder
if the extension needs to place methods on the models or the querybuilders prototype it needs to expose this functions
applyModelMethods
this function gets the models definition and the models classdefintion as arguments, it may attach own methods to the models definition
applyModelMethods: function(definition, classDefinition) {
classDefinition.doSomeFanyStuff = function() {
}
}
applyQueryBuilderMethods
this function gets the models definition and the querybuilders classdefintion as arguments, it may attach own methods to the querybuilders definition
applyQueryBuilderMethods: function(definition, classDefinition) {
classDefinition.doSomeFanyStuff = function() {
}
}
Events on the model instance
If you are going to listen to events you have to define listeners on your extension. If you are going to listen to the beforeSave event you have to define a method onBeforeSave on your extension.
