Rails - Nov 2006 - Newbie Q: Making code accessible by controller regardless of action

Hello,

I have a model:
--------------------------------------------------------
review.rb
--------------------------------------------------------
class Review < ActiveRecord::Base
  def self.published
    find(:all,
         :conditions => "she_published = TRUE and he_published = TRUE
and date_to_be_published <= now()")
  end
end
--------------------------------------------------------

And a controller:
--------------------------------------------------------
display_controller.rb
--------------------------------------------------------
class DisplayController < ApplicationController
  def index
    @published_reviews = Review.published
  end

  def show
    @review = Review.find(params[:id])
    @published_reviews = Review.published
  end

  def about
    @published_reviews = Review.published
  end
end
--------------------------------------------------------

And part of my layout:
--------------------------------------------------------
display.rhtml
--------------------------------------------------------
        <% for review in @published_reviews %>
          <%= link_to review.name, :controller => "display",
:action =>
"show", :id => review.id %>
          <br />
        <% end %>
--------------------------------------------------------

Right now the only way I can get things to work is to put the line
    @published_reviews = Review.published
in each def

Is there a place I can put this line just once so it''s accessible by
the layout, no matter what the action?

Thanks,

Sean

end

oops, typo

...def get_published_reviews...

If you put that at the top of a controller it will be available in all
the actions (if you put it in the application controller it will be
available to all actions in all controllers).
