Question

In my pages_controller.rb:

def home
   @date = Lesson.find(params[:created_at])
end

At this point I’m just trying to pull the date to try and visualize before I manipulate anything but when I try to call that @date instance variable in home.html.erb

The error I’m getting is Couldn't find Lesson without an ID but I’m not sure why. Any ideas?

The best solution to such problems – use scopes

in your lesson model add:

scope :by_date, order("created_at DESC")

there’s also default_scope
