Public API to change ItemFileReadStore url

[Josh Trutwin]

Per #6073 there is a clearOnClose param since 1.2 that allows a data store to change URL's without having to create a new store. But for this to work you have to set a psuedo-private member of the class:

<div id="store" dojoType="dojo.data.ItemFileReadStore" clearOnClose="true" url="/foo.php">

then:

dijit.byId("store")._jsonFileUrl = "/bar.php";
dijit.byId("store").close();
dijit.byId("store").fetch();

Would it be possible to replace the first line with something like:

dijit.byId("store").setUrl("/bar.php");

Or even:

dijit.byId("store").attr('url', '/bar.php');

Thanks,

Josh

oops - please add code formatting wiki tags...

This is already provided as of Dojo 1.4: ​http://bugs.dojotoolkit.org/ticket/9303

​http://docs.dojocampus.org/dojo/data/ItemFileReadStore#reloading-refreshing-itemfilereadstore-from-a-url-dojo-toolkit-1-4

As for the secondary request for dijit.attr, that cannot be used. dijit.byId() works for widgets (classes that extend from dijit._Widget). None of the datastores extend from that class, they are not visual widgets, and therefore are not addressable by dijit.ById?(), nor would they have the attr function of dijit._Widget subclasses.

Anyway, long-winded comment on the dijit.ById? part, but as for setting the URL ,you already can:

storeInstance.url = <whatever>

The code has logic to trap that being reset, and if clearOnClose is true and close() was called, the new url value will be used.

So, already fixed.

Thanks for the nice comment - should've searched the bug database first. :(

Is .fetch(); needed still to automatically update the store after changing .url?

[Jared Jurkiewicz]

The store will reload on the next call to fetch, either by a widget invoking it normally (As would ComboBox?, FilteringSelect?, etc, or by setting the query on grid, etc.).
