ExtJS4 store proxy url override - extjs

Question

I am trying to reuse a store by altering proxy url (actual endpoint rather than params). Is it possible to override proxy URL for a store instance wih the following syntax:
{
...some view config ...
store: Ext.create('MyApp.store.MyTasks',{proxy:{url:'task/my.json'}}),
}
if proxy is already well defined on the Store definition?
EDIT: AbstractStore source code sets proxy the following way
if (Ext.isString(proxy)) {
proxy = {
type: proxy
};
}
SOLUTION : store.getProxy().url = 'task/myMethod.json';

Answer 1

{
... some tab config ...
store: Ext.create('MyApp.store.MyTasks'),
listeners: {
afterrender: function(tab) {
tab.store.getProxy().url = 'task/myMethod.json'; //<--Saki magic :)
tab.store.load();
}
}
}

Answer 2

You cannot override the url of a proxy alone when creating a store. You will have to pass a complete proxy. This is because, the library replaces the proxy as a whole! So, what you can do is:
{
...some view config ...
store: Ext.create('MyApp.store.MyTasks',{
proxy: {
type: 'ajax',
url : 'task/my.json',
reader: {
type: 'json',
root: 'rows'
}
}
}),
}
Now another possibility is, changing the end point after you have the instance of store. If you need to load the store from a different endpoint, you can make use of the load method.
store.load({url:'task/others.json'});
Since, in your case you are trying to re-use a store, you can pass the whole proxy. Your store's (MyApp.store.MyTasks) constructor should be capable of handling the new config and applying it to the store... Here is an example:
constructor: function(config) {
this.initConfig(config);
this.callParent();
}

Use the store.setProxy() method. Link here:

I have a BaseStore which I use to store default settings.
Ext.define('ATCOM.store.Shifts', {
extend : 'ATCOM.store.BaseStore',
model : 'ATCOM.model.Shift',
constructor : function(config) {
this.callParent([config]);
this.proxy.api = {
create : 'shifts/create.json',
read : 'shifts/read.json',
update : 'shifts/update.json',
destroy : 'shifts/delete.json',
};
}
});
