Preload has_many associations with dynamic conditions

Question

I have a Place model and an Event model. Places can have events that take place on a specific date.

How can I set up my associatio

Answer 1

To solve the dynamic date problem, have you considered:

class Event < ActiveRecord::Base

  belongs_to :place

  scope :on_date, lambda {|the_date| where(start_date: the_date) }
  scope :on_or_after, lambda {|the_date| where('start_date >= ?', the_date) }
end

You could then do this:

@place = Place.find(params[:id]) # let's say...
@place.events.on_date(params[:chosen_date])

You can incorporate the eager loading stuff that others have mentioned too.
