Detecting a Mobile Browser
I have some CSS elements that won’t show correctly in mobile browsers, so I needed to exclude those elements from showing if it was a mobile browser.
I ended up using this code written by Ryan Bates’ on Railscasts
You can add this code to your application_controller.rb:
helper_method :mobile_device? private def mobile_device? if session[:mobile_param] session[:mobile_param] == "1" else request.user_agent =~ /Mobile|webOS/ end end
Then you can add this to where ever you do the check:
<% if mobile_device? %> your code <% end %>
For added flexibility, there are also some gems available that will check specifically for what browser it is.
