How can i add route in Rails admin view:

in views/rails_admin/cp_tabes.html.erb added below link.

<%= link_to 'Download Asset Report'.html_safe, asset_report_path(:format => 'csv'), :class => 'anchor-download-report-color' %>

i got undefined method `asset_report_path' for #<#Class:0x007fb02e8df348:0x007fb02e36e210>

thank you.

you have to add main_app.route_path or rails_admin.route_path or they won't work.
