I always do this when checking to see if a parameter exists and that it is not blank:

if params[:name] and !params[:name].empty? ... end

Is there a better way? a simpler way.

Rails defines an method 'blank?' that will work for any object, including nil. It returns true when it's called on a nil object, or an empty string, hash or array. So you can use

if !params[:name].blank?
