For the following controller:
thufir@arrakis ~/oreilly-recipes-categories $ cat app/controllers/
recipes_controller.rb -n | head -n 18 | tail -n 3
16 @recipe = Recipe.find(params[:id])
17 @categories= Category.find_all
18 end
thufir@arrakis ~/oreilly-recipes-categories $
http://oreilly-recipes-categories.googlecode.com/svn/trunk/app/
controllers/recipes_controller.rb
I just want to pull up the Category instance which belongs to this Recipe
instance. What should be on line 17 for that, please?
thanks,
Thufir
