Take the 2-minute tour ×  these are my Models  User -> has many
Pins Pins -> has many votes vote -> has a user_id and pin_id
How do I get all the Pins that are voted by the user in the most
effective way? Basically, I want to emulate this query in Ruby.
SELECT * FROM PINS a JOIN VOTES b ON a.id = b.pin_id WHERE
b.user_id = current_user.id  How can I do it? I can use,
db.execute, but can't I do anything without using SQL?  Thanks
for any help.  share|improve this question add comment  1 Answer
up vote 2 down vote accepted  Seeing that a vote belongs to a
user, a user should have_many votes, and you can just get the
pins via a has many through association  class User <
ActiveRecord::Base    has_many :votes    has_many voted_pins,
through: :votes, source: :pin  share|improve this answer add
