我正在教孩子们如何在 Rails 中做一个特定的应用程序，它需要一个关于某人对别人负责的资源。例如，这里有 2 个模型：

class User < ActiveRecord::Base
  attr_accessible :name
  has_many :responsible_fors, class_name: 'ResponsibleFor', foreign_key: 'responsible_by_ user_id'
  has_many :responsible_for_people, through: :responsible_fors
  has_many :responsible_bys, class_name: 'ResponsibleFor', foreign_key: 'responsible_for_user_id'
  has_many :responsible_by_people, through: :responsible_bys
end
class ResponsibleFor < ActiveRecord::Base
  attr_accessible :relationship, :responsible_by_id, :responsible_for_id
  belongs_to :responsible_by, class_name: 'User'
  belongs_to :responsible_for, class_name: 'User'
end

我没有在上面测试过这个特定的代码，但这个概念对我来说很有意义......虽然responsible和responsible for分别是形容词和介词，而不是 Rails 中的资源应该是的名词。有一个更好的方法吗？Rails 的多元化或其他操作会以其他方式扰乱它吗？有更好的名词吗？

我不认为你会对 Rails 和复数有任何问题：

1.9.3p385 :023 > "responsible_for".pluralize
=> "responsible_fors" 
1.9.3p385 :024 > _.singularize
=> "responsible_for"

也就是说，我会选择：

class User < ActiveRecord::Base
  has_many :responsibilities
  has_many :stakeholders, through: :responsibilities
  has_many :responsible_parties, through: responsibilities
end

class Responsibility < ActiveRecord::Base
  attr_accessible :relationship, :stakeholder_user_id, :responsible_party_user_id
  belongs_to :stakeholder
  belongs_to :responsible_party
end

我不确定这段代码是否运行（如果它运行我会感到震惊），但这是我用来命名的。
