Rails for Beginners Part 5: Routes and Route Types Discussion


I created a step-by-step guide based on this episode: You can view (and comment) at


Thanks for this, I've tried to follow the guide but get an error page:

wrong constant name [route]Controller inferred by Module from file
Possible ways to address this:

  • Tell Zeitwerk to ignore this particular file.
  • Tell Zeitwerk to ignore one of its parent directories.
  • Rename the file to comply with the naming conventions.
  • Modify the inflector to handle this case.

You are a really great teacher. great content.


I'm getting following error when i open http://localhost:3000/about
AboutController#index is missing a template for request formats: text/html

Please let me know how to resolve this issue.
