我一整天都在努力解决这个问题，但我解决不了。
我得到这个错误：
ActiveModel::MissingAttributeError in Users::RegistrationsController#add_data
can't write unknown attribute `[:drivlicense_nr, :birth_nation]`
user.rb:
class User < ApplicationRecord
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
has_one :person
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :confirmable,
:omniauthable, omniauth_providers: %i[facebook twitter google_oauth2]
#validate :password_complexity
private
def password_complexity
if password.present? && !password.match(/^(?=.*[a-z])(?=.*[A-Z])(?=.*d)./)
errors.add :password, 'must include at least one lowercase letter, one uppercase letter, and one digit'
end
end
def self.from_omniauth(auth)
# Either create a User record or update it based on the provider (Google) and the UID
where(email: auth.email, uid: auth.uid).first_or_create do |user|
user.token = auth.credentials.token
user.expires = auth.credentials.expires
user.expires_at = auth.credentials.expires_at
user.refresh_token = auth.credentials.refresh_token
user.provider = auth.provider
user.uid = auth.uid
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
user.skip_confirmation!
user.save!
end
end
def self.new_with_session(params, session)
super.tap do |user|
if data = session['devise.facebook_data'] && session['devise.facebook_data']['extra']['raw_info']
user.email = data['email'] if user.email.blank?
end
if data = session['devise.google_data'] && session['devise.google_data']['extra']['raw_info']
user.email = data['email'] if user.email.blank?
end
end
end
end
在person.rb中，我使用自定义primary_key，因为它们对我的应用程序非常重要。
class Person < ApplicationRecord
belongs_to :user, optional: true
has_many :cars
self.primary_key = %i[drivlicense_nr birth_nation]
VALID_FISCAL_CODE_REGEX = /A^[A-Z]{6}[0-9]{2}[A-Z][0-9]{2}[A-Z][0-9]{3}[A-Z]$z/
validates :fiscal_code, presence: true, length: {is: 16}, format: { with: VALID_FISCAL_CODE_REGEX }
end

我想做的是，在我通过谷歌/脸书注册后，用户必须填写另一张表格。现在，我还需要更新用户，使drivlicense和birth_nation(我的主键(具有相同的值。一旦程序do@person.save！Registration_Controller#add_data:
def add_data
@user = User.find_by_email(params[:email])
if request.get?
@person = Person.new()
render 'oauth_add_data'
elsif request.put?
@person = Person.new(person_params)
@user.update(drivlicense_nr: @person['drivlicense_nr'], birth_nation: @person['birth_nation'])
if @person.save!
flash[:success] = "Sign up process successful"
bypass_sign_in(@user)
redirect_to root_url
else
render 'new'
end
end
end
提前感谢您的帮助和耐心！

Rails使用id字段作为代理键，然后在应用程序和数据库层中强制该字段的唯一性。这样，您就不必担心创建复合主键(就像在学校一样(。
Rails依赖于很多约定而非配置，主键只是其中之一。您可以配置任何您喜欢的主键，但Rails会与您斗争，尤其是如果您想使用复合键。如果你真的需要，有一块宝石可以帮助你做到这一点，但我会远离它，因为它会带来复杂性。
