How to redirect to 404 page in Rails?

Small tutorial that will help you to redirect user to a "fake" 404 page, using Rails
31 October 2017   5792

Rails has this functionality built in already. If you want to show a 404 page, create a render_404 method (or not_found ) in ApplicationController like this:

def not_found
  raise ActionController::RoutingError.new('Not Found')
end

Rails also handles AbstractController::ActionNotFound, and ActiveRecord::RecordNotFound the same way.

This does two things better:

It uses Rails' built in rescue_from handler to render the 404 page, and 2) it interrupts the execution of your code, letting you do nice things like:

  user = User.find_by_email(params[:email]) or not_found
  user.do_something!

without having to write ugly conditional statements.

As a bonus, it's also super easy to handle in tests.
