Rubyonrails get public actions from a controller

February 15, 2007

If you tuned in last week, I was blog'n about getting a list of controllers in a Rubyonrails project. Here's something I wrote to get the list of actions for a specific conroller, I keep it in a helper file:

# c = controller
# s = selected
def get_action_options( c, s='' )
  str = '<option value=""></option>'
  file = RAILS_ROOT + "/app/controllers/#{ c }_controller.rb"
  if File.exists? file
    f = File.new( file, 'r' )    
    while line = f.gets
      line = line.strip
      break if line =~ /^private/
      if line =~ /^def\ /
        action = line.gsub( /^def\ /, '' )
        str << "<option value='#{ action }'"
        str << ' selected="selected"' if action == s
        str << ">#{ action }</option>"
      end
    end
    f.close
  end
  str
end
