Optimizing queries with acts_as_taggable_on
Using Rails 3.1 and gem 'acts-as-taggable-on'
version 2.1.1.
I have a class:
class Meal < ActiveRecord::Base
acts_as_taggable_on :foods
...
end
I have several different scopes on Meal that I use on a dashboard-type page. In the controller, I call, for example:
def index
@today = Meal.from_today
@yesterday = Meal.from_yesterday
end
I iterate over @today
and @yesterday
separately on the dashboard page.
I'd like to optimize the database calls. Right now, I call <%= meal.food_list %>
in the view while iterating over each meal in both @today
and @yesterday
. For each meal, it queries the database to find the foods.
I've been trying to chain the q开发者_Go百科ueries in the controller with something like:
@today = Meal.from_today.includes(:foods)
but that doesn't work. Given this situation, how should I optimize the queries? Am I misusing acts-as-taggable-on
?
