JsonStore - Load single record with a restful url?

All,

I have a JsonStore backing a form panel in开发者_Go百科 my extjs app. I want to have the jsonStore load a single record based on an id value, but haven't found a good way to do that yet, and still keep the url restful.

My first attempt was to add a param to the jsonstore load() method with the id in it. That only adds the id as a request param, not attached to the url:

http://my-app/users/?id=123

instead of what i want:

http://my-app/users/123

Can someone help me out with this?

You can manually construct the URL that the store uses to query for data (via the implicit HttpProxy it creates for the URL). So your loading function would look like:

function store_refresh() {
  json_store.proxy.conn.url = 'http://my-app/users/' + user_id;
  json_store.reload();
}
