工廠女孩：自動分配父對象

Question

我剛剛進入工廠女孩，我遇到了一個困難，我敢肯定應該更容易。我只是無法將文檔轉換成一個工作示例。

假設我有以下型號：

class League < ActiveRecord::Base 
    has_many :teams 
end 

class Team < ActiveRecord::Base 
    belongs_to :league 
    has_many :players 
end 

class Player < ActiveRecord::Base 
    belongs_to :team 
end 

我想要做的是這樣的：

team = Factory.build(:team_with_players) 

，並把它打造了一堆的球員對我來說。我嘗試這樣做：

Factory.define :team_with_players, :class => :team do |t| 
    t.sequence {|n| "team-#{n}" } 
    t.players {|p| 
     25.times {Factory.build(:player, :team => t)} 
    } 
end 

但這未能對:team=>t部分，因爲t是不是一個真正的Team，這是一個Factory::Proxy::Builder。我有有有一個隊分配給一個球員。

在某些情況下，我想建立一個League並讓它做類似的事情，創建多個球員的多個球隊。

我錯過了什麼？

Answer 1

Factory.define :team do |team| 
    team.sequence(:caption) {|n| "Team #{n}" } 
end 

Factory.define :player do |player| 
    player.sequence(:name) {|n| "John Doe #{n}" } 
    player.team = nil 
end 

Factory.define :team_with_players, :parent => :team do |team| 
    team.after_create { |t| 25.times { Factory.build(:player, :team => t) } } 
end 

Answer 2

如何：

Factory.define :team_with_players, :class => :team do |t| 
    t.sequence { |n| "team-#{n}" } 
    t.players do |team| 
    25.times.collect { |n| team.association(:player) } 
    end 
end
