为什么不能阻止dept_tech角色在dept_tech角色无法访问的部门中创建用户?
我使用cancan进行自动化,使用simple_form进行视图。 我有一个用户模型和一个部门模型。
class User < ActiveRecord::Base
belongs_to :department
...
end
class Department < ActiveRecord::Base
has_many :departments
...
end
我还有一个能力模型
class Ability
include CanCan::Ability
def initialize(user)
Rails.logger.debug {" >>>>>>> user id: #{user.id} ......
if user.role? :admin
...
elseif user.role? :dept_tech
Rails.logger.debug {" >>>>>>> role 6 ......
can :manage, User, :department_id => user.department_id
can :read, Department, :id => user.department_id
Rails.logger.debug {" >>>>>>> user.department: #{user.department_id}}
end
end
end
和用户控制器:
load_and_authorize_resource
...
def new
respond_to do |format|
Rails.logger.debug {" >>>> here"}
format.html # new.html.erb
end
Rails.logger.debug {" >>>> there"}
end
...
还有一个
load_and_authorize_resource
部门控制员。
和使用simple_form的_form视图助手
<% simple_form_for @user, :html => {class => 'form-horizontal' } do |f| %>
<%= f.input :email %>
Rails.logger.debug {" >>>> view"}
<%= f.association :department %>
....
<% end %>
这很有效,dept_tech只能为部门做索引和展示行动。它也适用于索引,为用户显示操作。但是,当执行对用户的新操作时,部门的collection_select显示所有部门,而不仅仅是dept_tech的部门。
我们的想法是dept_tech只能创建(管理)他自己部门的用户。
这是日志,显示选择是在部门选择的位置使用而不是在视图中完成。

日志显示,在视图中调用SQL并不奇怪。这是一个simple_form问题吗?怎么解决?
