Redirect to canonical route in without trailing slash in Rails 3

Question

On Rails 3, I\'m trying to redirect from a URL without a trailing slash to the canonical URL that has a slash.

match \"/test\", :to => redirect(\"/test/\"         


        

Answer 1

You can force the redirect at the controller level.

# File: app/controllers/application_controller.rb
class ApplicationController < ActionController::Base

  protected

  def force_trailing_slash
    redirect_to request.original_url + '/' unless request.original_url.match(/\/$/)
  end
end

# File: app/controllers/test_controller.rb
class TestController < ApplicationController

  before_filter :force_trailing_slash, only: 'test'  # The magic

  # GET /test/
  def test
    # ...
  end
end
