Create model with it's relations

I'm trying to migrate my project from Rails 5.0 to 5.2

Project extensively uses creation of related models through .build_%related_model%, it was working on rails 5.0 and now it's broke. Does this functionality removed, or should i use another syntax?

class User < ActiveRecord::Base
  belongs_to :profile, inverse_of: :user
end

class Profile < ActiveRecord::Base
  has_one :user, inverse_of: :profile
end

new_user = User.new
new_user.build_profile
new_user.save

Previously this code created both User and his Profile. Now this will create only User, without Profile.

Any ideas how to fix this?

accepts_nested_attributes_for :profile fixed this exact issue, but many other have popped up.

I had to stop this update and rollback everything.

    create_table :users do |t|
      t.integer :profile_id
      t.timestamps
    end
  end
end
class CreateProfiles < ActiveRecord::Migration[5.1]
  def change
    create_table :profiles do |t|

      t.timestamps
    end
  end
end
class User < ApplicationRecord
  belongs_to :profile, inverse_of: :user
end
class Profile < ApplicationRecord
  has_one :user, inverse_of: :profile
end

tested it out all worked. Copied code to answer since its not readable in comment. Your problem must be somewhere else do u get any errors or paste migration files to under question
