Question

我的Rails应用程序中有两种类型的设计身份验证。一个是LDAP，另一个是数据库身份验证。我想根据用户选项制作它。我尝试了将该选项作为函数并传递值的一些事情。但它显示我错误：uninitialized constant Devise::Models::Authentication (NameError)

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :authentication, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  def authentication
    flag=1
    if flag == true
        auth = "database_authenticatable"
    else
        auth = "ldap_authenticatable"
    end
    "#{auth}"
  end
end

现在我想让这段代码工作，之后我会自己添加flag选项。提前谢谢。

Answer 1

class User < ActiveRecord::Base if flag == 1 devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable else devise :ldap_authenticatable, :registerable, :recoverable, :rememberable, :trackable end end

Answer 2

使用类似的东西：

devise *devise_options

def devise_options
  [:authentication, 
  :registerable, 
  :recoverable, 
  :rememberable, 
  :trackable, 
  :validatable, 
  (flag ? :database_authenticatable : :ldap_authenticatable)]
end

根据用户的选择设置认证选项
