How do I use Active Record to get these records via the associations in rails?

I have the @user variable, and i have resources table, and then I have a favorites table which is merely user_id and resource_id

@user.resources.each works obviously

@user.favorites.first.resource works fine, except i want all of the resources.

@user.favorites.resources does not work

resource.rb

  belongs_to :category
  belongs_to :user
  has_many :favorites
  has_many :resource_tags
  has_many :tags, :through => :resource_tags

user.rb

  has_many :resources
  has_many :favorites

favorite.rb

  belongs_to :resource
  belongs_to :user

Try:

@user.favorites.includes(:resource).collect(&:resource)

That should eager load the resource from all the User's favorites and then the collect should return them as an Array.
