How to update corresponding record with has_one association?

I have a User model that has_one Bike and user accepts_nested_attributes_for a bike.

class User < ApplicationRecord
  has_one :bike

  accepts_nested_attributes_for :bike
end

and

class Bike < ApplicationRecord
  belongs_to :profile
end

On my controller I pass bike's parameters like this:

params.require(:purchase).permit(bike_attributes: [:id, :type, :brand])

after that I am updating the current_user with the new info

def update
  current_user.update(purchase_params)
end

My problem is that with every new change for a current user, a new bike record gets created. For example If I update the information about bike 10 times for the current user, then 10 bike records will be created and only the last one Bike.last will hold the right user_id.

How to prevent database from that and really update only one corresponding record?

Thank you.

Check if the Bike is sending across the id attribute in the params. You should include a hidden id field for the bike if it's not currently there.
