如何配置专家显示属于父母债券

Question

我的用例是，如果用户有角色:agency，他可以看到客户。但我必须使用客户和机构之间的链接来验证这一点。看看下面的代码：

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！

这样解决了我的问题。我希望它能帮助别人。

我的模型Agency有许多Clients：

class Agency < ApplicationRecord 
    has_many :clients 

    resourcify 
end 

我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型号：

class UsersRole < ApplicationRecord 
    belongs_to :user 
    belongs_to :role 
end 

最后，我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
