In Sinatra, best way to serve iPhone layout vs. normal layout?
- by Doug
I'm writing a Sinatra app which needs to render different layouts based on whether the user is using an iPhone or a regular browser. I can detect the browser type using Rack-Mobile-Detect but I'm not sure of the best way to tell Sinatra which layout to use.
Also, I have a feeling that how I choose to do this may also break page caching. Is that true?
Example code:
require 'sinatra/base'
require 'haml'
require 'rack/mobile-detect'
class Orca < Sinatra::Base
use Rack::MobileDetect
helpers do
def choose_layout
if request.env['X_MOBILE_DEVICE'] == :iPhone
# use iPhone layout
else
# use normal layout
end
end
end
before do
# should I use a before filter?
choose_layout()
end
get '/' do
haml :home # with proper layout
end
end #Class Orca
