我正在使用sinatra，我想使用嵌入式1-1
实现嵌入文档这是我的主要收藏品，只嵌入一个环境 TestSuite类 包括Mongoid :: Document
field :testSuiteName
field :introduction
field :itemsToTest
field :dateCreation
attr_accessible :testSuiteName,:introduction,:itemsToTest,:dateCreation
embeds_one :environment
embeds_many :steps
end
每个TestSuite都嵌入了许多步骤
class Step
include Mongoid::Document
field :stepRole
field :stepOrderNum
embedded_in :testSuite
embedded_in :environment
has_one :function
end
运行testSuite我必须设置嵌入许多步骤的测试环境
class Environment
include Mongoid::Document
embedded_in :testSuite
embeds_many :steps
end
get '/createTestSuite' do
name=params[:testName]
intro=params[:introduction]
items=['data','shemas']
test1=TestSuite.create()
test1.testSuiteName="firstOne"
test1. introduction="my first Test Suite"
test1.itemsToTest=["data","shemas"]
test1. dateCreation="23/01/214 18:18"
test1.environment.create()
test1.environment.steps.create(stepRole: "inserer donneés",stepOrderNum: "2")
问题：

如何在嵌入环境文档的情况下创建testSuite？
