Sencha localStorage.getItem() returns null in model - sencha-touch-2

Question

In my model, I have the following code:
Ext.define('Proximity.model.CandidateblocklistModel', {
extend: 'Ext.data.Model',
requires: ['Ext.data.proxy.LocalStorage'],
config: {
store:'Proximity.store.CandidateblockStore',
fields: [
{ name: 'id', type: 'id' },
{ name: 'name', type: 'string' },
{ name: 'img', type: 'string' },
{ name: 'designation', type: 'string' },
{ name: 'summary', type: 'string' },
{ name: 'experience', type: 'string' },
{ name: 'industry', type: 'string' },
{ name: 'functionnml', type: 'string' },
{ name: 'role', type: 'string' }
],
proxy : {
type : 'ajax',
url : Proximity.util.Config.getBaseUrl() + '/index.php/candidate/getcandidateblock',
withCredentials: false,
useDefaultXhrHeader: false,
extraParams: {
"id": localStorage.getItem('id')
},
reader : {
filters: [
Ext.create('Ext.util.Filter', {
property: 'name'
})
]
}
}
}
});
The id in the local storage is already set before calling this model. I can see the id in localStorage by inspect element in Chrome, and I did get the value of it in other section. But I only can't get it in my model when I am trying to use it in proxy. I want to get data from my web service based on the value of the localStorage.
Code in my proxy:
extraParams: {
"id": localStorage.getItem('id')
},
I want to get the id from localStorage here.
Please help me.

I think the following code works
proxy : {
type : 'ajax',
url : Proximity.util.Config.getBaseUrl() + '/index.php/candidate/getcandidatebest',
withCredentials: false,
useDefaultXhrHeader: false,
extraParams: {
id: localStorage.getItem('id')
},
reader : {
filters: [
Ext.create('Ext.util.Filter', {
property: 'ind_id',
property: 'fun_id',
property: 'role_id',
property: 'id'
})
]
}
}
and then use the filtering facility of store to pass the localstorage value. To do that give filter permission remoteFilter: true, this.

Ahh i found an awesome trick. Instate of setting extraParams in your Model, set it in the store of the same model.
My new code is as follows.
Ext.define('Proximity.model.RecruiterbestlistModel', {
extend: 'Ext.data.Model',
config: {
store:'Proximity.store.RecruiterbestStore',
fields: [
{ name: 'id', type: 'int' },
{ name: 'name', type: 'string' },
{ name: 'img', type: 'string' },
{ name: 'company', type: 'string' },
{ name: 'summary', type: 'string' },
{ name: 'address', type: 'string' },
{ name: 'industry', type: 'string' },
{ name: 'functionnml', type: 'string' },
{ name: 'role', type: 'string' }
],
proxy : {
type : 'ajax',
url : Proximity.util.Config.getBaseUrl() + '/index.php/recruiter/getrecruiterbest/',
withCredentials: false,
useDefaultXhrHeader: false,
reader : {
filters: [
Ext.create('Ext.util.Filter', {
property: 'ind_id',
property: 'fun_id',
property: 'role_id'
})
]
}
}
}
});
Look i have removed the code
extraParams: {
"id": localStorage.getItem('id')
},
from Model. And in my store i have added
listeners: {
beforeload: function(store){
this.getProxy().setExtraParams({
id: localStorage.getItem('id')
});
return true;
},
So my new store code is as follows
Ext.define('Proximity.store.RecruiterbestStore', {
extend: 'Ext.data.Store',
alias: 'store.recruiterbeststore',
config: {
model: 'Proximity.model.RecruiterbestlistModel',
autoLoad: true,
remoteFilter: true,
storeId: 'recruiterbeststore'
},
listeners: {
beforeload: function(store){
this.getProxy().setExtraParams({
id: localStorage.getItem('id')
});
return true;
}
}
});
And its solved my problem.
But now i am having another issue. after running sencha app build native(using cordova bild), again i am having same issue, the extraParam are not added to proxy request.
Please help me to solve this.
