Question

我刚刚进入工厂女孩，我遇到了一个我确信应该更容易的困难。我只是无法将文档扭曲成一个有效的例子。

假设我有以下型号：

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

我想做的是：

team = Factory.build(:team_with_players)

让它为我建立一堆球员。我试过这个：

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:team=>t部分失败了，因为t实际上不是Team，而是Factory::Proxy::Builder。我将球队分配给球员。

在某些情况下，我想建立一个League并让它做类似的事情，创建多个拥有多个玩家的团队。

我错过了什么？

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

这个怎么样：

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
