The correct way to get the segament key in url when used with hash_routes?

[Billy Zheng]

Following is a example:

```rb

# app.rb

r.on Integer do |id|

  @insider_id = id

  r.hash_routes('insiders/show')

end

```

```rb

class App

  hash_routes('insiders/show') do

      is true do |r|

      result = RetrieveInsiderHistory.result(r.params.merge(insider_id: @insider_id))

      # ...

      end

  end

 end

```

Sure, as describe on README, we can access @insider_id which defined on `main` route in hash_routes, but, i am not sure if this the expected way to do this. anyway, when inspect the `r` variable, we can see App::RodaRequest object is there. 

[7] pry(#<App>)> r                                                                             
#<App::RodaRequest GET /insiders/1>

so, if there exists a way, to get the `1` Integer matcher from `r`?

Thank you.

Yes, accessing the instance variable is definitely the recommended way to do this.

You could do:

  r.path.split('/').last.to_i

But you are much better off accessing the instance variable you created earlier.

Thanks,
