Custom 404 Rails error pages

All credit for this snippet is due to [Henrik Nyh](http://henrik.nyh.se/2008/07/rails-404). Put this in application\_controller.rb: ```ruby alias_method :rescue_action_locally, :rescue_action_in_public if RAILS_ENV == 'development' def render_optional_error_file(status_code) if status_code == :not_found activate_authlogic render_404 else super end end def render_404 respond_to do |type| type.html { render :template => "errors/error_404", :layout => 'application', :status => 404 } type.all { render :nothing => true, :status => 404 } end true # so we can do "render_404 and return" end ```
