在数据库rake中设置不可访问的属性：填充

Question

我有一个叫做Treating的模型，它需要同时存在'requestor'和'requestee'。这些属性在处理模型中都不可访问。这里的模型：

class Treating < ActiveRecord::Base 
    attr_accessible :intro, :proposed_date, :proposed_location 

    validates :intro, presence: true, length: { maximum: 190 } 
    validates :requestor_id, presence: true 
    validates :requestee_id, presence: true 

    belongs_to :requestor, class_name: "User" 
    belongs_to :requestee, class_name: "User" 

    default_scope order: 'treatings.created_at DESC' 

end 

我试图填充这个耙档测试数据库，sample_data.rake：

namespace :db do 
    desc "Fill database with sample data" 
    task populate: :environment do 
     ... 

     requestors = User.all(limit: 6) 
     50.times do 
      intro = Faker::Lorem.sentence(5) 
      requestors.each do |requestor| 
       requestee = User.find(rand(1..6)) 
       requestor.sent_treatings.create!(intro: intro) 
      end 
     end 
    end 
end 

除非我做：请求在处理模型的可访问属性，并按照“ intro：intro'with'requestee：requestee'in'requestor.sent_treatings.create！（intro：intro）'line of my rake file，当我运行rake db时，我会得到一个Validation错误：填充说'requestee是空白'：

rake aborted! 
Validation failed: Requestee can't be blank 

Tasks: TOP => db:populate 

1）[more imporant]如何在我的rake文件中设置'requestee'，而无需在模型中访问'requestee'？ 2）我在'50.times.do'循环中声明了'requestee'变量：'requestee = User.find（rand（1..6））'。什么是更好的方式来声明这与我如何在'requestors.each do | requestor |'中声明'requestor'变量相似？

非常感谢！

namespace :db do 
    desc "Fill database with sample data" 
    task populate: :environment do 
     ... 

     requestors = User.all(limit: 6) 
     requestees = User.find((1..6).to_a) 
     50.times do 
      intro = Faker::Lorem.sentence(5) 
      requestors.each do |requestor| 
       requestee = requestees.sample #random array member, Ruby 1.9+ 
       treating = requestor.sent_treatings.build(intro: intro) 
       treating.requestee = requestee 
       treating.save! 
      end 
     end 
    end 
end
