#6991 closed enhancement (fixed)

[patch][cla] New (plus near-trivial SMD)

Reported by: guest Owned by: Kris Zyp
Priority: high Milestone: 1.2
Component: DojoX Data Version: 1.1.1
Keywords: Cc: [email protected]…, [email protected]…, alex
Blocked By: Blocking:


This patch provides two interfaces to Wikipedia:

  • via SMD, for use with dojox.rpc.Service
  •, for higher level access

The SMD is dead simple; it just lets us talk to the API provided by the MediaWiki software, and does little other parameter checking. It gives us a fairly "raw" interface to the API.

The dojo data store provides two basic operations: 1) retrieve titles of articles containing a given text string, and 2) retrieve details for a page by title. It's basically just a customized, with some extra processing to make it easier to deal with the data returned.

The patch also contains supporting documentation and tests:

  • DOH test suite for the RPC/SMD version
  • A simple page grabber demo for the RPC version
  • DOH test suite for the data store
  • A simple page grabber demo for the data store
  • Patch written & submitted under CLA by Revin Guillen

I think this looks really cool, a few though though: First, I would think you could use the ServiceStore? paradigm of lazy loading item as instances of dojo.Deferred. If you did this, then I don't think you would need to override isItemLoaded, loadItem, and getValue, ServiceStore? would handle all of those correctly for you. In order to create a Deferred version of the lazy loaded item (that only loads once), I do something like:

for each of the stub/title only items results[i] = dojo.mixin(new dojo.Deferred(),results[i]); create a Deferred object (function(item){

var connectId = dojo.connect(item,"addCallbacks",function(){

dojo.disconnect(connectId); var spec = {

query : item; onItem : dojo.hitch(item,item.callback) };




Although seeing the awkwardness of this, perhaps it would be helpful if I provided a "createLazyItem" function in the ServiceStore?, something you could create lazy items with like this:

results[i] = this.createLazyItem(results[i],function(item){

return item; return the query for the fetch


Also, your code seems to be begging the ServiceStore? for a labelAttribute property for getLabel and getLabelAttributes :). I can certainly add that.

Last, I wonder if _fixupStarElements is worth it's weight. Is it that bad to write item*? instead of You can keep it if you want, just doesn't seem worth it to me.

Anyway, I think this looks really great, and thanks for using my ServiceStore?!

Actually, please hold off on the review until I get a second version in; I've been in communication with kriszyp about changing up the ServiceStore? to make this implmentation simpler, so I have a replacement path in development. I'll try to submit it today.

I can take ownership of this since I did the first review with Revin, is that all right?

comment:7 Changed 14 years ago by guest

OK, with Kris' recent changes to the ServiceStore in trunk, we've got a much leaner WikipediaStore in the (newly replaced) attached patch. Have at it.

I have reviewed it and it looks good to me. I can commit it in unless someone else wants to review it as well. Kris

Kris: have at. Please ensure that unit tests have full coverage before committing.

Revin, Kris: nice work = )
