Question

I’m a front end guy getting more and more into using sinatra. I’m building an app currently and am trying to find an elegant way to DRY up the routes in my myapp.rb file.

Currently I have these routes:

get '/' do
  haml :content 
end

get '/content' do
  haml :content, :layout => :empty
end

get '/show_layout' do
  haml :show_layout
end

get '/conversion' do
  haml :conversion, :layout => :empty
end

get '/optout' do
  haml :optout, :layout => false
end

get '/terms' do
  haml :terms, :layout => :empty
end

With regards to the templates, I know I can do something like this to combine them:

get '/:name' do
  haml params[:name].to_sym
end

But what about the layouts? There are only 2 layouts here, layout.haml and empty.haml (:layout, and :empty), 3 if you count :layout => false

Is this something that is best done using a hash? Something like:

layout_map = {
  "" => "",
  :content => "",
  :show_layout => "",
  :conversion => :empty,
  :optout => false,
  :terms => :empty    
}

get '/:name' do
  haml params[:name].to_sym, :layout => layout_map[:name]
end

Seems like its on the right track but I can’t get it to work properly.

Thanks for all your help.

Thanks for all your help everyone. Ended up going with this as my solution due to some other requirements of the app.

get "/:base_route/" do
  haml :"#{params[:base_route]}/content", :layout => :"#{params[:base_route]}/layout"  
end

get "/:base_route/:name" do
  layout_map = {
    :landing => :layout,
    :content => :empty,
    :show_layout => :layout,
    :conversion => :empty,
    :terms => :empty    
  }        
  haml :"#{params[:base_route]}/#{params[:name]}", :layout => :"#{params[:base_route]}/#{layout_map[params[:name].to_sym]}"
end
