我的用例是,如果用户有角色:agency
,他就可以看到客户端。但我必须使用客户端和代理商之间的链接来验证这一点。看下面看看我的代码:
class Agency < ApplicationRecord
has_many :agency_clients
has_many :clients, through: :agency_clients
resourcify
end
class AgencyClient < ActiveRecord::Base
belongs_to :agency
belongs_to :client
end
class Client < ApplicationRecord
has_many :agency_clients
has_many :agencies, through: :agency_clients
resourcify
end
class ClientPolicy < ApplicationPolicy
def show?
user.has_role?(:admin) || user.has_role?(:client, record)
end
class Scope < Scope
def resolve
if user.has_role? :admin
scope.all
elsif user.has_role? :client, :any
scope.with_role(:client, user)
else
scope.none
end
end
end
end
谢谢!

这种方式解决了我的问题。我希望它能帮助别人。
我的模型Agency
有很多Clients
:
class Agency < ApplicationRecord
has_many :clients
resourcify
end
我的User
有关系:
class User < ApplicationRecord
has_many :users_roles
has_many :roles, through: :users_roles
has_many :agencies, through: :roles, source: :resource, source_type: 'Agency'
rolify
...
end
需要创建UsersRole
模型:
class UsersRole < ApplicationRecord
belongs_to :user
belongs_to :role
end
最后,我的ClientPolicy
:
class ClientPolicy < ApplicationPolicy
def show?
user.has_role?(:admin) || user.has_role?(:client, record)
end
class Scope < Scope
def resolve
if user.has_role? :admin
scope.all
elsif user.has_role? :client, :any
scope.with_role(:client, user)
elsif user.has_role? :agency, :any
scope.where(agency_id: user.agencies.pluck(:id))
else
scope.none
end
end
end
end
