Forgive me if this is a newb question but I was wondering how they got the current user's id in the User model here:
Listing 10.39
I've tried reading it again and again and i still can't figure it out :(
class User < ActiveRecord::Base
.
.
.
def feed
# This is preliminary. See "Following users" for the full implementation.
Micropost.where("user_id = ?", id)
end
.
.
.
end

feed
is an instance level method so self
will have user object. So id
is equivalent to self.id
.
For example:
Assume you have user_method
in User
model.
def user_method
puts self #prints user object
puts self.id #prints user id
puts id #prints user id
end
user = User.create(user_attributes)
user.user_method
Similarly, feed
is called on some user
object.
