CanCan的筛选器索引 [英] Filter index for CanCan

问题描述

我正在尝试根据能力过滤索引。我正在使用 wice_grid gem在索引中创建表格，并为票证添加条件，可以使用：conditions 。

I am trying to filter the index according to the ability. I am using the wice_grid gem to make a table in the index, and to add a condition to tickets, we could use something called :conditions.

我试图这样说：

@tickets_grid = initialize_grid(Ticket,
                                :include => [:user, :employee_department, :state],
                                :conditions => [Ticket.accessible_by(current_ability)])

这是行不通的。我正在寻找任何建议。

This is not working, though. I'm looking for any suggestions.

更新：：conditions 的工作方式如 ActiveRecord 所以我想我需要一个查询来查找角色并检测当前能力

Update: :conditions is working like ActiveRecord so I guess I need a query to look up through roles and detect the current ability

推荐答案

您正在寻找的是current_ability.model_adapter（Ticket，：index）.conditions其中Ticket是您的模型，而：index是您的访问类型。

What you are looking for is current_ability.model_adapter(Ticket, :index).conditions where Ticket is your model and :index is your access type.

因此在您的情况下应该是：

so in your case it should be:

@tickets_grid = initialize_grid(Ticket,:include => [:user, :employee_department, :state],:conditions => current_ability.model_adapter(Ticket, :index).conditions)
