Question

我正在教孩子们如何在Rails中使用特定的应用程序，它需要一个关于某人对其他人负责的资源。例如，这里有两个模型：

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

我之前没有测试过这个特定的代码，但这个概念对我有意义......虽然responsible和responsible for分别是形容词和介词，但不是Rails中的名词作为资源应该是。有一个更好的方法吗？ Rails的多元化或其他操纵会以其他方式扰乱这种情况吗？有更好的名词吗？

我认为你不会对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"

那就是说，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会运行（如果有的话，我会感到震惊），但这就是我用来命名的内容。

如何命名一个形容词或介词的Rails资源？
