How you can break up large Ability class in CanCan – Gists

更复杂的场景：如果您有几个不同的重叠权限集,您可以尝试这种方法：

# app/models/ability.rb
 
class Ability
  include CanCan::Ability
 
  def initialize(user)
    self.merge Abilities::Everyone.new(user)
 
    if user
      self.merge Abilities::Admin.new(user) if user.admin?
      self.merge Abilities::Authenticated.new(user)
    else
      self.merge Abilities::Guest.new(user)
    end
  end
end
 
# app/models/abilities/admin.rb
module Abilities
  class Admin
    include CanCan::Ability
 
    def initialize(user)
      # define abilities here ...
    end
  end
end
 
# app/models/abilities/everyone.rb
...

对于其余的文件,依此类推.
