Question

I’ve got a Rails app and a Sinatra app inside it:

routes.rb:

mount MySinatraApp => "/streaming"

sinatra app:

class MySinatraApp< Sinatra::Base
  ...
  before do
    puts 'hello from sinatra!'
  end
  ...
end

I expectedly want the filter to run only on the requests starting with /streaming..., but, what surprises me, the filter runs on every request to the whole Rails app. What can I do with such a behaviour?
I can add a regexp filter after before, but I don’t think it’s a good style.

Answer 1

Well, I replaced

mount MySinatraApp => "/streaming"

with

match "/streaming" => SinatraQuoridor, :anchor => false

and filters started to word as expected.
Allthough, I do not understand clearly why it is happening: according to this article, mount should just call match with :anchor => false, so the routes should be the same. But the behaviour differs.
