Question

just encountered the following code in RoR 3.2.8. Does that mean that self belongs to the merge function or to the class?

results.merge(
        profile: self)

Any help will be appreciated

Answer 1

Depends on the context. ie. where you found this line of code.

class Profile
  def foo
    results.merge(profile: self)
  end
end

p = Profile.new
p.foo

In this case “self” will be referring to the object “p”, which is the current object in the context where “self” is used.
