An optional model-to-javascript tree renderer for mongoid_nested_set

Can be used to turn association select to a tree select, like this:

#checkboxes
    -# with simple_form
    = f.association :categories, as: :check_boxes, collection: Category.all

    -# with formtastic
    = f.input :categories, as: :check_boxes, collection: Category.all

    -# without any
    - Category.each do |c|
      = check_box_tag "item[category_ids][]", c.id, @item.category_ids.include?(c.id)

#tree.controls.input{style: 'width: 220px;'}

:javascript
    var categories = #{Dynatree::Renderer.new(Category.nested_set.all, f.object.categories).render()};
    $(function(){
        $('#checkboxes').hide();

        $("#tree").dynatree({
            checkbox: true,
            selectMode: 3,
            classNames: {
                active: "dynatree-active-no"
            },
            children: categories
        });

        $("form").submit(function() {
            var tree = $("#tree").dynatree("getTree"),
                arr = tree.serializeArray(),
                sel = $('#checkboxes');
            sel.find(':checked').prop('checked', false);
            $.each(arr, function(k, v) {
                sel.find('[value=' + v.value + ']').prop('checked', true);
            });
        });
    });
