Sorting / Order in a list from Firebase

[EddyVerbruggen]

Wait, are you saying you fixed #46 then?

[jlooper]

No, we turned out attention to making the app work great on iOS :) - let me comment the other issue

[EddyVerbruggen]

Once I figure out #46 for your app I'll take a look at this one. But it's a toughie.

Just to note, the ordering is super nutty atm

If I add a console.log statement in the query function you linked to above then I won't see it in my log so I don't think the query is executed.

Instead, in the constructor of the same class there's a firebase.addValueEventListener which I think is the one actually retrieving the data here.

You could btw sort clientside to avoid using the query function at all.

[jlooper]

the query is hit by the event listener when the data changes. So if you add an item, you should see that query run. It's also hit when the page first loads to retrieve the list, or any time the database data is altered. I would think that it would be more efficient for the plugin to handle the sorting on the database side, right? If it is too hard, though, we can work on client side sorting. 👍 thanks!

[EddyVerbruggen]

Hey Jen, did you try adding that log statement? Seriously, I don't think the query runs at all so sorting is never applied.

[jlooper]

ooh, I think you're right. We have changed the code to make the sync work. Debugging now. Thanks for the heads up!

[jlooper]

It has to be sorted using a pipe if you want to done client side

@jlooper I've also faced the same problem. Sorting in firebase.query especially with firebase.QueryLimitType.LAST is a bit invalid. I'd to use a custom sort filter over the list again!

I am unable to sort data using singleEvent: false is that it expected behavior? The sorting works when I use singleEvent: true

Issue #405 seems to be relevant here. I feel piping on the client side is a hacky work-around seeing as it'll be a major hit to performance on bigger queries.
