Question

I have this method in application_helper

def is_controller?(*args)
 "active" if args.include?(params[:controller])
end

This works.

%= is_controller?("x") %>

This is not working.

%= is_controller?("x", "y", "z", "t") %>

Any help will be appreciated.

In the console it behaves as you expect

irb(main):020:0> def is_controller?(*args)
irb(main):021:1>    "active" if args.include?("x")
irb(main):022:1>   end
=> nil
irb(main):023:0> is_controller?("x")
=> "active"
irb(main):024:0> is_controller?("y")
=> nil
irb(main):025:0> is_controller?("x","y")
=> "active"

so the problem would seem to be that your params[:controller] value is not what you think it should be …
