I am trying to do some tricks with routes. And I need to use optional route parameter in Padrino. I googled that solution for this are "()" parenthesis. I couldn't find in docs.

But when I try to use

get :sort, :with => [:order, :asc, '(:search)'] do

them, mustermann is giving me classic error for missing parameter

cannot expand with keys [:asc, :order], possible expansions: [:asc, :order, :search]

when I try to call 

url(:sbirka, :sort, :order => "id", :asc => @asc)

I also tried different style

get :sort, "/:order/:asc/(:search)" do

with the same result

Please any suggestions how to do this?

Since Padrino is based on Sinatra, every routing pattern possible with Sinatra should be possible in Padrino as well. From Sinatra's excellent README file, introductory 'Routes' section:

Route patterns may have optional parameters

In your case, assuming :search is optional, I would try:

get '/:order/:asc/:search?' do
  # your  code
end

  • Thanks so much! I will try, it is working like route, I must change my url helpers for sinatra style, padrino style url(:sbirka, :sort, :order => "country", :asc => @asc) does not work, I will write as soon as I will try – Mlok Apr 10 '18 at 11:56
  • It is not working :( If I use :search? as in example, I get 404 not found, when I put :search? away, it is working. – Mlok Apr 10 '18 at 17:41
