Fetched data does not get evaluated correctly (selectize empty) about angular-selectize HOT 12 OPEN

this seems to be a persistent issue with dynamic options.

i'm building out a list of columns from an uploaded CSV which is not available at the time of the config being loaded, since it has to be uploaded, and the scope variable is then updated with the list of columns, but I'm unable to see the selectize dropdown updated once the list of columns is available.

So what I did for now (but seems like a hack) is the following:

onInitialize: function(selectize){
  _.each(vm.currentUser.movies, function(movie) {
    selectize.addOption(movie);
    selectize.addItem(movie._id);
  });
}    

which seems to work. So the problem is that
a) the options are not populated before
b) my model is an array of full objects, thus I either need to _.pluck(vm.currentUser.movies, '_id'); or add each via iteration.

A quick fix that I've found around that is to use the default valueField and labelField. So I've used objects like: {text:'the label', value:'the value'} and it's working fine. I didn't have the time to investigate further but so it looks like somewhere in the directive we are always using the defaults valueField and labelField even if some others were specified in the configuration.

Well that would mean that someone should change the models/object to suit the selectize dropdown which is imo unacceptable..

+1 needs way to bind to objects properly

I had a similar issue. I found out that I was initializing $scope.config (whatever variable referenced in the config attribute of the directive) too late in my controller, so the binding didn't work: it is done only once, late updates are ignored.
I have just put the init of this scope variable in the body of the controller and it worked fine...

For our projects, I made a SelectizeService which wraps calls to the Selectize component exposed from onInitialize.

I let Selectize do the loading of its options, so it just manages the loading class and updates correctly the options.
I do it this way:

    /**
     * Starts to load the data (by calling the loadFunction) after setting the loading class on the Selectize component.
     * @see SelectizeService#finishLoading
     */
    service.initLoading = function(selectizeControl, loadFunction)
    {
        // loadingFinished is a function given by Selectize, to call with the results once they are fetched
        var wrappedLoadFuntion = function(loadingFinished)
        {
            // Memorize the given function
            selectizeControl._finalizeLoading = loadingFinished;
            // Do the data loading call
            loadFunction();
        };
        // load() sets the loading class on the control,
        // then call the given function with an argument which is a function to call with the results.
        selectizeControl.load(wrappedLoadFuntion);
    };

    /**
     * To call on data loading completion, with the control (to remove the loading class),
     * and the received data (optional if options are created by other means).
     */
    service.finishLoading = function(selectizeControl, data)
    {
        selectizeControl._finalizeLoading(data);
    };

A bit convoluted, but it works.

@machineboy2045 Any thoughts on this one?

from angular-selectize.

Try the latest version. I patched a couple bugs yesterday. If that doesn't help I'll look into it some more.

@xeroxoid is this issue still present in v3?

from angular-selectize.

Yep the issue is still present and it will always be until two-way object binding is in place. ATM you still have to pluck or set strings for values into setValue or addItem so you always need an onInitialize if you want to pre-select saved values.

Just found the following -
if my ng-model = "myModel"
following seems to work for me:
$scope.myModel = ["value1","value2","value3"] as long as they are these are part of the model.
