Hey I am trying to one-one relation in active record ..

I have a model called person 

class Person < ActiveRecord::Base
	has_one :personal_info
end

whose migration is like this

class CreatePeople < ActiveRecord::Migration
  def change
    create_table :people do |t|
      t.string :first_name
      t.integer :age
      t.string :last_name

      t.timestamps null: false
    end
  end
end

And I have other model called personal info, whose model is this

class PersonalInfo < ActiveRecord::Base
  belongs_to :person
end

migration is this

class CreatePersonalInfos < ActiveRecord::Migration
  def change
    create_table :personal_infos do |t|
      t.float :height
      t.float :weight
      t.references :Person, index: true, foreign_key: true

      t.timestamps null: false
    end
  end
end

I think I have not created the model properly, and I went ahead and changed :Person to :person in the above migration. And did 
rake db:migrate. 

Now in the console

vamsi = Person.first

vamsi.persona_info = PersonalInfo.create height: 57 ,weight: 75

would give me can't write to unknown attribute person_id .. can anyone help me with this
