firebase-util / ionic / normalizedCollection issue..

[Steven Hastie]

Hey, 

I was hoping someone could help me with this issue i'm having.

I'm using a bunch of normalizedCollections in my ionic app. The issue i'm having is if, for whatever reason, changing between views triggers a controller to reload it will get stuck loading because the noralizedCollection in the controller cannot seem to reload if it has already been loaded previously. 

It just gets stuck. It doesn't return any message to the console. Nothing. Just refuses to load.

Any ideas?

Any help would be greatly appreciated.

Steven,

A nuanced problem like this is going to require a minimal, complete, verifiable, example for us to be any help. Try creating a fiddle or plunker.

☼, Kato

I have this in my controller:

        var information= getinformation();

        information.$loaded()

        .then(function (x) {

            // ***

            $scope.info = information;

        })

and this is my factory: 

    return function (uid) {

        var ref = new Firebase(FURL);

        var sessionArray = new Firebase.util.NormalizedCollection(

        [ref.child("childName").orderByChild("child").equalTo("something"), "something"],

        [ref.child("childName").limitToFirst(20), "anotherthing", "something.name"]

        ).select(

            "something.name",

            "something.city",

            "something.country",

            "anotherthing.message"

        ).ref();

        var sessionInfo = $firebaseArray(sessionArray);

        return sessionInfo;

    }

Any time a controller tries to load for a second time... for example if I have the state cache set to false or the state resets. It will just stall and get stuck trying to load the collection for a second time. 

Hope this helps.

Thanks

Scratch that.... I realised $loaded can only be used once and that's what is causing the issue. Now to figure out how to solve this issue.

There's no reason in this (very terse and minimal) line of code you've provided to use $loaded. Just $scope.information = getInformation() should work fine. If you provide a repro, we can be more helpful.

The reason I am using $loaded is to prevent the loader from disappearing before the data has been loaded. Is there a better way to display the loader until the data has been retrieved from firebase?
