I am trying to use this extension, I am using '<%= link_to 'Notify me', new_stock_request_url(variant) , :style => 'color:red'%> in order to call stock_requests/new and create a notification, but give error , even changing url to '/stock_requests/new?stock_request=66'
private method permit' called for "66":`

How i call new stock request??
