Using ng-filter with source object about angular-deckgrid

[akoenig]

I have not tested it yet. The deckgrid will be rendered again if the object count of the source collection has changed. Any other change reflects without a re-rendering. So my guess is that it will work. Let me know if you've tried it :)

Am I wrong in thinking that this function won't trigger if the array order changes?

  Deckgrid.prototype.$$onModelChange = function $$onModelChange (oldModel, newModel) {
        var self = this;

        if (oldModel.length !== newModel.length) {
            self.$$createColumns();
        }
    };

Have you considered using angular.equals instead?

  if (!angular.equals(oldModel, newModel){
    self.$$createColumns();
  }

It seems to work well for me

Well, it's complicated. :) Consider the scenario that you have a lot of objects in your deckgrid (which was my use case while developing the directive). When using the angular.equals method, changing one property of an object in the source collection means triggering the whole grid rendering again. An use case that works fine for small collections or not many object property changes.

One option could be to integrate a "strict mode", like:

deckgrid-strict="true" => !angular.equals(oldModel, newModel)

deckgrid-strict="false" (default) => oldModel.length !== newModel.length

Another option would be to use angular.extend within your code (if you have a source collection in which every object has the same property structure). This is useful if you want to switch positions without losing references.

Let me know what you think.
