| class User < ActiveRecord::Base | |
| has_many :memberships, :include => :roles | |
| has_many :projects, :through => :memberships | |
| end | |
| User.first.memberships | |
| #=> eager loads "roles" | |
| User.first.projects | |
| #=> does NOT eager loads "roles" | |
| # Conclusion: ":through" does not takes intermediate relations' ":include" options | |
| # Right ? |
