I'm coding on a little web app using http://padrinorb.org (haml+lesscss) for both mobile (android/iPhone/iPad) and desktop users, and as such, I wish to display slightly different html/css for the different devices.
To determine the various clients I use rack-mobile-detect which works great so far.
To get the layout to become layouts/application.mobile i use these helpers/wrappers for render
def preferred_extension
if request.xhr?
"js"
elsif env["X_MOBILE_DEVICE"]
"mobile"
else
"html"
end
end
def preferred_layout
if preferred_extension.eql? "html"
"application"
else
"application.#{preferred_extension}"
end
end
def render_preferred filename
filename = "#{filename}.#{preferred_extension}"
if request.xhr?
layout_file = false
else
layout_file = "layouts/#{preferred_layout}".to_sym
end
render filename, :layout => layout_file
end
However, this doesn't help me when dealing with partials... and it feels like somebody must have a better solution for this than just wrapping render and partial in a helper.
What I want is to not sprinkle my controllers and views with weird code just to render the correct partial/file with the correct layout.
I would like the render discovery to find out which file to use, and falling back to filename.haml if there is no filename.#{preferred_extension}.haml.
In rails there is this mime type thing that I used in a previous project, but I haven't find anything similar for padrino (sinatra)
