Rails console does not recognize new class name after a rename_table migration

Let's say I wrote a migration to change one of the table name.

class RenameFooToBar < ActiveRecord::Migration
  def change
    rename_table :foos, :bars
  end
end

After db:migration and a reload! in rails console I was expecting to be able to use the class Bar to refer to the renamed table i.e. Bar.create(name: 'bar1'). But it gives me a NameError, so what did I missed or how do I setup this relation manually?

Renaming table is not enough, you need to rename app/models/foo.rb to app/models/bar.rb and also change the class name inside this file from class Foo < ActiveRecord::Base to class Bar < ActiveRecordBase. Also scan for any usage of constant Foo.
