Properties

Name Description
alias @author Ed Spencer * In-memory proxy. This proxy simply uses a local variable for data storage/retrieval, so its contents are lost on every page refresh. * Usually this Proxy isn't used directly, serving instead as a helper to a {@link Ext.data.Store Store} where a reader is required to load data. For example, say we have a Store for a User model and have some inline data we want to load, but this data isn't in quite the right format: we can use a MemoryProxy with a JsonReader to read it into our Store: * //this is the model we will be using in the store Ext.define('User', { extend: 'Ext.data.Model', fields: [ {name: 'id', type: 'int'}, {name: 'name', type: 'string'}, {name: 'phone', type: 'string', mapping: 'phoneNumber'} ] }); * //this data does not line up to our model fields - the phone field is called phoneNumber var data = { users: [ { id: 1, name: 'Ed Spencer', phoneNumber: '555 1234' }, { id: 2, name: 'Abe Elias', phoneNumber: '666 1234' } ] }; * //note how we set the 'root' in the reader to match the data structure above var store = Ext.create('Ext.data.Store', { autoLoad: true, model: 'User', data : data, proxy: { type: 'memory', reader: { type: 'json', root: 'users' } } });
