Question

我需要将跳过验证方法添加到我的会话控制器，但我不确定将omniauth定义为和基本登录为什么。即他们都来自班级用户，但在会话控制器中，我把

  def create
   user = User.from_omniauth(env["omniauth.auth"])   
 **user.from_omniauth.skip_name_validation = true**
   etc etc

然后还要为模型中的方法添加验证，以粗体显示，并将其添加到我的会话控制器，以便能够绕过每个登录的两个实例。

我的会话控制器

  def create
   user = User.from_omniauth(env["omniauth.auth"])

  unless user.present?
    user = User.find_by(email: params[:session][:email].downcase)
     if user && user.authenticate(params[:session][:password])
      log_in user
      redirect_to user
      # Log the user in and redirect to the user's show page.
    else
      # Create an error message.
      flash.now[:danger] = 'Invalid email/password combination'
      render 'new'
    end    
  else        
    log_in user
    redirect_to user
  end
end

我的模特.rb

class User < ApplicationRecord

  before_save { self.email = email.downcase }
  validates :name, presence: true, length: { maximum: 50 },
**unless: :skip_name_validation**
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, length: { maximum: 255 },
                    format: { with: VALID_EMAIL_REGEX },
                    uniqueness: { case_sensitive: false },
                  **unless: :skip_email_validation**
  has_secure_password
  validates :password, presence: true, length: { minimum: 6 }, allow_nil:true,
**unless: :skip_password_validation**

 **attr_accessor :skip_name_validation, :skip_email_validation, :skip_password_validation**

 **attr_accessor :skip_User, :skip_self**

**validate :User, unless: :skip_User**
**validate :self, unless: :skip_self**

  def User.digest(string)
    cost = ActiveModel::SecurePassword.min_cost ? BCrypt::Engine::MIN_COST :
                                                  BCrypt::Engine.cost
    BCrypt::Password.create(string, cost: cost)
end

  def self.from_omniauth(auth)
    where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
      user.provider = auth.provider
      user.uid = auth.uid
      user.name = auth.info.name
      user.oauth_token = auth.credentials.token
      user.oauth_expires_at = Time.at(auth.credentials.expires_at)
      user.save!
    end
  end
end
