I work for a project of mobile application and I have a problem to retrieve informations by using proxy in a store.
It’s an application to manage Train Stations, and for a Station, I call a WebService which retrieve the 10 next trains ( in json ).
I have 2 classes, TrainStation ( Gare in french 😉 ) and Train
the method in Gare to retrieve the Trains:
getListTrains: function(TR3A) {
console.log('plop');
var trains = Ext.create('Ext.data.Store', {
model: 'Train',
proxy: {
type: 'ajax',
url: 'http://eclernet-mobile.dev.dsit-hp.sncf.fr/Trainservice.svc/GetListTrainsAtGare/'+TR3A,
method: 'POST',
headers: {
'Accept': 'application/json'
},
reader: {
type: 'json'
}
}
});
console.log(trains);
}
the class Train ( which extend Model to using the method ):
Ext.define('Train', {
extend: 'Ext.data.Model',
config: {
codeMission: null,
numero: null,
sens: null,
dessertes: null,
voie: null,
heureProbable: null,
heureTheorique: null,
voiePrecedente: null,
quai: null,
retard: null
},
constructor: function(config) {
this.initConfig(config);
},
});
When I call my method with a valid train station, my console.log(trains); retrieve an empty object …
