Question

I’ve got a little issue with rails, I want to be able to do something like this to avoid multiple redirections :

def render_not_found
  not_found
end

private

  def not_found
    redirect_to website_url(@website), :status => 301 and return return
  end

return return doesn’t work of course!

Using: rails 3.2.0

There’s a few ways to do this. One way is to define and raise a custom error, and have a handler that redirects when that happens.

application_controller.rb

Class ApplicationController < ActionController::Base

  around_filter :catch_errors

  def catch_errors
    yield
  rescue SiteNotFoundError
    redirect_to website_url(@website), :status => 301
  rescue ActiveRecord::RecordNotFound
    render 404
  rescue ...
    ...
    ...
  end
end

class SiteNotFoundError < StandardError; end

in your controller

def your_action
  raise SiteNotFoundError if (some condition)
end

or in a before filter

before_filter :ensure_valid_site

def ensure_valid_site
  raise SiteNotFoundError if ....
end
