I have data in an external database which can be accessed via JSON. Now I want to provide different views on these data sets (eg. different sorting, ..). Is it possible to use one single store for this or do I need two stores accessing the same URL except with a different sorter?
My example code looks like this:
Ext.define('MyApp.store.MyStore', {
extend: 'Ext.data.Store',
requires: [
'MyApp.model.MyModel'
],
config: {
autoLoad: true,
model: 'MyApp.model.MyModel',
storeId: 'MyJsonStore',
proxy: {
type: 'ajax',
url: 'http://localhost/index.php?data=MyData&format=json',
reader: {
type: 'json'
}
},
sorters: [
{
direction: 'DESC',
property: 'MyRating'
},
{
direction: 'ASC',
property: 'MyLabel'
}
] } });
And one view should now render a list sorted by the rating and a second one should display a list sorted by the label.
Is there a way to prevent querying the DB twice?
Thanks - I just started out with Sencha Touch and ExtJS --- therefore please excuse my simple question ;)
Somehow I couldn't find any smart solution by asking Google for this basic task..
You don't have to worry about anything unless your two views are presented at the same time. Just re-sort the same store locally.
If they are presented at the same time you will have to create a copy of a store. Otherwise they will show exact same information.
