Question

我们的应用程序使用Devise进行注册，并且与用户模型和Profile模型完美配合。

将注册信息从表单保存到Users表，并在SQL上的Profiles表中使用其他信息创建配置文件，并使用user_id嵌套。

Omniauth Facebook正在努力将内容保存到用户模型，但我希望保存名称，从Facebook Auth获取用户名到Profile模型，如Devise注册。

TABLE用户

| id | email | encrypted_password | reset_password_token | reset_password_sent_at | remember_created_at | sign_in_count | current_sign_in_at | last_sign_in_at | current_sign_in_ip | last_sign_in_ip | created_at | updated_at | role_id | provider | uid |

TABLE个人资料

| id | user_id | username | name | lastname | gender | birthday | created_at | updated_at |

MODEL User.rb

class User < ActiveRecord::Base has_one :profile, :dependent => :destroy, autosave: true accepts_nested_attributes_for :profile # Include default devise modules. Others available are: # :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :omniauthable, :omniauth_providers => [:facebook] belongs_to :role before_create :set_default_role def self.find_for_facebook_oauth(auth) where(auth.slice(:provider, :uid)).first_or_create do |user| user.provider = auth.provider user.uid = auth.uid user.email = auth.info.email user.password = Devise.friendly_token[0,20] 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 end end private def set_default_role self.role ||= Role.find_by_name('registered') end end

MODEL Profile.rb

class Profile < ActiveRecord::Base belongs_to :user validates :username, presence: true, length: {maximum: 255}, uniqueness: { case_sensitive: false }, format: { with: /\A[a-zA-Z0-9]*\z/, message: "deve contar apenas letras e números" } validates :name, presence: true, length: {maximum: 255} validates :lastname, presence: true, length: {maximum: 255} validates :gender, presence: true, inclusion: %w(m f) validates :birthday, presence: true end

CONTROLLER application_controller.rb（处理自定义字段的许可）

class ApplicationController < ActionController::Base # Prevent CSRF attacks by raising an exception. # For APIs, you may want to use :null_session instead. protect_from_forgery with: :exception before_action :configure_permitted_parameters, if: :devise_controller? protected def configure_permitted_parameters devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password, :password_confirmation, :provider, :uid, profile_attributes: [:name, :lastname, :username, :birthday, :gender, :id]) } devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email, :password, :remember_me, :provider, :uid) } devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:username, :email, :password, :password_confirmation, :current_password) } end end

任何人都知道如何让Omniauth Facebook像Devise注册一样运行为用户创建配置文件，集成两个模型User和Profile而不会破坏Devise注册：P？

谢谢：）

我不知道facebook注册或登录您的应用程序的流程所以我只是假设当用户点击登录或注册Facebook时，您的应用程序基本上从Facebook获取电子邮件并创建只有当该电子邮件不在数据库中时才新用户，否则只需将其签名即可。

要实现此目的，您需要覆盖find_for_facebook_oauth(auth)方法。您可以在方法中执行类似的操作

def self.find_for_facebook_oauth(auth)
  if user = User.find_by_email(auth.info.email)  # search your db for a user with email coming from fb
    return user  #returns the user so you can sign him/her in
  else
    user = User.create(provider: auth.provider,    # Create a new user if a user with same email not present
                       uid: auth.uid,
                       email: auth.info.email,
                       password: Devise.friendly_token[0,20])
    user.create_profile(name: auth.info.name, # you need to check how to access these attributes from auth hash by using a debugger or pry
                        #your other profile attributes

                        )
    return user

  end
end

然后你的回调方法将是相同的

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    # You need to implement the method below in your model (e.g. app/models/user.rb)
    @user = User.find_for_facebook_oauth(request.env["omniauth.auth"])

    if @user.persisted?
      sign_in_and_redirect @user, :event => :authentication #make sure user is confirmed else it'll throw an error
      set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
    else
      session["devise.facebook_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end

如果您的流程类似于雅虎，您使用来自Facebook的数据呈现带有自动填充字段的表单，那么您可以简单地在user方法中初始化profile和find_for_facebook_oauth(auth)语句

user = User.new(#user attributes)
user.build_profile(#profile attributes)
return user # and then return initialised user

由于用户不在db中，它将在facebook回调方法中执行else块，并将使用自动填充的字段呈现登录页面。

这是设计从omniauth保存信息的地方

def self.find_for_facebook_oauth(auth)
  where(auth.slice(:provider, :uid)).first_or_create do |user|
    user.provider = auth.provider
    user.uid = auth.uid
    user.email = auth.info.email
    user.password = Devise.friendly_token[0,20]
  end
end

所以只需添加要保存在那里的字段

user.username = auth.info.nickname

如果你想实时看到哈希在回调中引发异常

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
   def facebook
     raise request.env["omniauth.auth"].to_yaml # <----------
     .
     .
     .

或在omniauth-facebook-gem页面中有一个示例，在某些情况下，引发异常对于调试非常有用，问候

设计模型用户和个人资料+ Omniauth Facebook
