Question

post.rb Model

   after_update :assign_owner

   def assign_owner
      self.owner = "test"
   end

The above method works in terminal but does not change the value of Post.new.owner in Rails. What am I missing?

Answer 1

This is an after update (object needs to be saved) so

post = Post.new.save

Then

post.owner  # will be test

If you wanna do this you may want to use after_initialize

for e.g in post.rb

class Post < ActiveRecord::Base
  protected
    def after_initialize
      self.owner = "test
    end
end
