How will this deal with 500K rows?

[JehandadK]

I have an entity which has many to many relation with another entity which has 500K rows. Will multi select work?

Not for now. An autocomplete widget is the only way to deal with this cardinality, it's on the todo list.

Or maybe you can add to your API a content-range? and customize pagination ?

example :

// Pagination Global Var
        var rangeStart = 0;
        var itemsPerPage = 10;
        var rangeEnd = itemsPerPage - 1;

        function pagination(page, maxPerPage) {
            rangeStart = (page - 1) * maxPerPage;
            rangeEnd = page * maxPerPage;                        
        }

        function totalItems(response) {
            var items = response.headers('content-range');
            if (items !== null) {
                var total = items.split("/").pop();
                return total;
            } else {

            }

        }

        function headerRange() {
            return {
                range: 'items=' + rangeStart + '-' + rangeEnd
            };
        }

And call your functions in entity list :

.headers(headerRange)
.perPage(itemsPerPage)
.totalItems(totalItems)
.pagination(pagination)

The problem isn'y on the API side, it's with the way we deal with Reference widgets.

Also, pagination configuration will soon change a lot, see #211

Thanks to #508, autocomplete is now part of ng-admin, and this WILL scale!
