我正在尝试定义一种能力:
# customer.rb
class Customer
include Mongoid::Document
has_many :accounts
end
class Account
include Mongoid::Document
belongs_to :site
end
# ability.rb
can :manage, Customer, accounts: { :site_id.in => user.managed_site_ids }
# customers_controller.rb
Customer.accessible_by(current_ability)
它总是返回空结果,我不确定,但我认为是因为 mongoid 不支持连接查询。你知道什么是错的,或者其他的选择吗?
