How Rails Action Name Works Today I was trying to control what rendered on a page based on which controller action called it, and discovered the action_name method. It’s located in actionview: pry> method(:action_name).source_location => ["/Users/jake/.rvm/gems/ruby-2.2.3/gems/actionview-4.2.4/lib/action_view/helpers/controller_helper.rb", 10] Add this to your view code, and it you’ll get the relevant action: pry> action_name => "index" Same partial, different context: pry> action_name => "drafts" This method would allow conditionals like this (written in HAML): - if action_name == 'index' Welcome to the index. - else Welcome to the drafts. https://github.com/rails/rails/blob/master/actionview/lib/action_view/helpers/controller_helper.rb#L10

Semicolon Breaks Everything “Select isn’t broken.” If you’re working on a CSS file, and none of your changes are being applied, check for typos, crashed servers, misplaced files, etc. Once you’ve ruled out simple mistakes, you might have a syntax error like this: .klass { opacity: 0.5; }; The trailing semicolon is incorrect, and none of the CSS below it can be understood by the browser. Change this to: .klass { opacity: 0.5; } There may be some environments where a broken CSS file fails loudly; Code Sandbox or Codepens are not among them. If you’re changing CSS and nothing is happening, start looking for syntax errors. ...
