Tree menu handle failure calls on store
I have a simple tree menu defined with a store attached. The store calls an url for the response containing the items it has. If the user is not logged in the servers responds:
Code:
{"message": "Invalid permissions", "data": {}, "success": false}
My question is: how do I handle this response to catch it in a failure type method as a callback probably and show the user that error message or maybe redirect him to the login page.
My tree is as follows:
Code:
Ext.define('AP.view.layout.MenuTree' ,{
alias : 'widget.mainMenuTree',
extend: 'Ext.tree.Panel',
border: false,
useArrows: true,
rootVisible: false,
initComponent: function(){
Ext.apply(this, {
viewConfig: {
getRowClass: function(record) {
if (!record.get('leaf')) {
return 'group ';
}
return record.get('cls');
}
},
store: Ext.create('Ext.data.TreeStore', {
model: 'Menu',
proxy: {
type: 'rest',
url : AP_ROOT_URL + 'menu/',
reader: {
type: 'json',
successProperty: 'success'
}
}
})
});
this.callParent();
}
})
I see it has a successProperty but how do I catch the failure message?
