设计/ LDAP - 在db中保存额外的ldap属性

标签: devise ldap ruby-on-rails-3.1 before-save

我正在使用最新的Devise和ldap插件运行rails 3.1。我已经交换了使用电子邮件地址的默认行为,现在使用Novell eDir中的uid属性作为我的用户字段。

我可以登录,我会根据根路线等重定向。

我现在想要的是从我的ldap获取电子邮件和名为category的自定义属性并将其插入到数据库中。我试图让before_save工作。

class User < ActiveRecord::Base

    before_save :get_ldap_email
    before_save :get_ldap_category

    # Include default devise modules. Others available are:
    # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and  :omniauthable
    devise :ldap_authenticatable, :rememberable, :trackable

    # Setup accessible (or protected) attributes for your model
    attr_accessible :uid, :category, :email, :password, :password_confirmation, :remember_me

    def get_ldap_email
        self.email = Devise::LdapAdapter.get_ldap_param(self.uid, "mail")
    end

    def get_ldap_category
        self.category = Devise::LdapAdapter.get_ldap_param(self.uid, "category")
    end

end
我可能很蠢但是我不能让它起作用。我在登录时从我的视图中获得以下输出:

NoMethodError in Devise::SessionsController#create

我做错了什么?很想得到一些帮助!

我不确定它对你有帮助,但你可以这样使用它:

self.firstname = Devise::LdapAdapter.get_ldap_param(self.username, 'givenName').first
self.lastname = Devise::LdapAdapter.get_ldap_param(self.username, 'sn').first    
self.email = Devise::LdapAdapter.get_ldap_param(self.username, 'mail').first  

当您的搜索取得少量结果而不是一个结果时会发生这种情况,您将获得零值 这是一个总是将数组模具返回到ldap性质的hack: 在文件config / initializer / devise.rb中添加以下补丁:

module Devise
  module LdapAdapter
    class LdapConnect
      def ldap_param_value(param)
        filter = Net::LDAP::Filter.eq(@attribute.to_s, @login.to_s)
        ldap_entry = nil
        @ldap.search(:filter => filter) {|entry| ldap_entry = entry}

        if ldap_entry 
          if ldap_entry[param]
            DeviseLdapAuthenticatable::Logger.send("Requested param #{param} has value #{ldap_entry.send(param)}")
            value = ldap_entry.send(param)           
          else
            DeviseLdapAuthenticatable::Logger.send("Requested param #{param} does not exist")
            #changes here
            value = nil
          end
        else
          DeviseLdapAuthenticatable::Logger.send("Requested ldap entry does not exist")
          value = nil
        end
      end
    end
  end
end

仔细阅读https://github.com/cschiewek/devise_ldap_authenticatable/issues/69并将补丁与原始代码进行比较,以便了解。
