Filtered length when paginating

[jmorrell]

Currently there is no way of knowing how many models are in the collection after filtering if you're also paginating. This is definitely information you may want to show in the UI.

Perhaps an extension to the paginated collection would be helpful here: getUnpaginatedLength() or something along those lines?

Yep, would totally make sense in my world.

For anyone else stopping by, I'll include the line you posted on Twitter, thanks :)

"proxy._filtered.length" does the trick for now.

[jmorrell]

Currently you can access the filtered collection within an obscura collection via _filtered, so you can still get access to it.

var proxy = new Obscura(collection);
proxy.filterBy({ a: 2 });
proxy.setPerPage(10);

collection.length; // the original collection length
proxy.length;  //  the paginated length
proxy._filtered.length; // the filtered length

Though I'd want an official API for this. Should be simple to add.

@marcfalk This should be fixed now :)

var proxy = new Obscura(collection);
proxy.filterBy({ a: 2 });
proxy.setPerPage(10);

collection.length; // the original collection length
proxy.length;  //  the paginated length
proxy.getFilteredLength(); // the filtered length
