Tip: Automatically annotate rails views

PROBLEM: When your application grows, and your views become more complex, it can be hard to know where an element on an HTML page is rendered from.

There’s a simple solution!

Just add this line:

# config/environments/development.rb
  # Annotate rendered view with file names.
--  # config.action_view.annotate_rendered_view_with_filenames = true
++  config.action_view.annotate_rendered_view_with_filenames = true

Works for:

• templates
• partials
• ViewComponents !!!
