    <p>I created a Grid component with the store configuration like this:</p> <pre><code> //Create the store config.store = new Ext.data.Store({ restful: true, autoSave: false, batch: true, writer: new Ext.data.JsonWriter({ encode: false }), reader: new Ext.data.JsonReader({ totalProperty: 'total', root: 'data', fields: cfg.fields }), proxy: new Ext.data.HttpProxy({ url:cfg.rest, listeners:{ exception: { fn: function(proxy, type, action, options, response, arg) { this.fireEvent('exception', proxy, type, action, options, response, arg); }, scope: this } } }), remoteSort: true, successProperty: 'success', baseParams: { start: 0, limit: cfg.pageSize || 15 }, autoLoad: true, listeners: { load: { fn: function() { this.el.unmask(); }, scope: this }, beforeload: { fn: function() { this.el.mask("Working"); }, scope: this }, save: { fn: function(store, batch, data) { this.el.unmask(); this.fireEvent('save', store, batch, data); }, scope: this }, beforewrite: { fn: function(){ this.el.mask("Working..."); }, scope: this } } }); </code></pre> <p>Note: Ignore the fireEvents. This store is being configured in a shared custom Grid Component.</p> <p>However, I have one problem here: Whatever CRUD actions I did, I always come out with N requests to the server which is equal to N rows I selected. i.e., if I select 10 rows and hit Delete, 10 DELETE requests will be made to the server.</p> <p>For example, this is how I delete records:</p> <pre><code>/** * Call this to delete selected items. No confirmation needed */ _deleteSelectedItems: function() { var selections = this.getSelectionModel().getSelections(); if (selections.length &gt; 0) { this.store.remove(selections); } this.store.save(); this.store.reload(); }, </code></pre> <p>Note: The scope of "this" is a Grid Component.</p> <p>So, is it suppose to be like that? Or my configuration problem? I'm using Extjs 3.3.1, and according to the documentation of <code>batch</code> under Ext.data.Store,</p> <blockquote> <p>If Store is RESTful, the DataProxy is also RESTful, and a unique transaction is generated for each record.</p> </blockquote> <p>I wish this is my configuration problem.</p> <p><em>Note: I tried with <code>listful</code>, <code>encode</code>, <code>writeAllFields</code>, <code>encodeDelete</code> in <code>Ext.data.JsonWriter</code>... with no hope</em></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
