Sencha touch 2.2 sql proxy not inserting data - extjs

Question

I successfully tried sencha touch app example showed here
They are using store proxy type as localstorage, its working good and then i changed the proxy type to sql as shown below
Ext.define('notesApp.store.Notes', {
extend : 'Ext.data.Store',
requires : 'Ext.data.proxy.Sql',
config : {
model : 'notesApp.model.Note',
proxy : {
type : 'sql',
database: "SqlProxyTest",
table: "Notes",
id : 'notes-app-store'
},
sorters : [{property : 'dateCreated', direction : 'DESC'}],
grouper : {
sortProperty : 'dateCreated',
direction : 'DESC',
groupFn : function(record) {
if(record && record.data.dateCreated) {
return record.data.dateCreated.toString();
}
return '';
}
}
}
});
There is no error.
I can insert data and i can see the record in list view, but chrome resource showing "The Node table is empty".
If i refresh the browser the record is gone from the list.
Am i missing anything or is it right way to use sql proxy in sencha touch ?

Answer 1

If you have change your model (add a field) you have to drop the table and recreate it.
And when you add a new row on your datastore be sure to put all fields.
Example if i have a model with firstName, lastName, email :
// This one is not added cause email is absent
Ext.getStore('Users').add([{
firstName: 'Toto',
lastName: 'test',
}]);
// This one is added
Ext.getStore('Users').add([{
firstName: 'toto',
lastName: 'test',
email : 'toto#test.te'
}]);

The mistake i did was, i created id for the record i am trying to insert as they showed in that demo example, when i changed below model from
Ext.define("NotesApp.model.Note", {
extend: "Ext.data.Model",
config: {
idProperty: 'id',
fields: [
{ name: 'id', type: 'int' },
{ name: 'dateCreated', type: 'date', dateFormat: 'c' },
{ name: 'title', type: 'string' },
{ name: 'narrative', type: 'string' }
]
}
});
to
Ext.define('notesApp.model.Note', {
extend : 'Ext.data.Model',
config : {
fields : [
{ name : 'dateCreated', type : 'string', dateFormat : 'D'},
{ name : 'title', type : 'string'},
{ name : 'narrative', type : 'string'}
],
validations : [
{type : 'presence', field : 'dateCreated'},
{type : 'presence', field : 'title', message : 'Please enter a title for the note!'}
]
}
});
Everything works fine.
