您如何授权访问由 controller 处理的页面,而没有相应的 model 与 Cancancan?

[英]How do you authorize access to a page dealed by a controller without corresponding model with Cancancan?

问题

没有相应 model 的 Spree 管理员 controller,其访问试用重定向到其他页面。

对应的尝试代码:

module Spree
  module Admin
    class TutorialsController < Spree::Admin::BaseController
      authorize_resource :class => false

      def index
      end
    end
  end
end

app/models/spree/ability_decorator.rb中添加了以下内容:

  can :manage, :'tutorial'
  can :manage, :'admin/tutorial'
  can :manage, :'admin_tutorial'
  can :manage, :'spree/admin/tutorial'
  can :manage, :'spree_admin_tutorial'

但是这些授权都不能解决问题。 当然,在这个地方添加can:manage, :all将使页面可以根据需要访问,所以这绝对是接近所需但不那么宽松的解决方案。 即使在 controller 中使用skip_authorization_check也无法解决问题,请求将被重定向到具有这些相应初始日志的admin/products

在进行了几次其他重定向之后,请求会导致前面所述的路径。

在这种情况下,毕竟不需要特殊能力。 Spree::BaseController设置正确的权限以授予目标访问权限,这与Spree::Admin::BaseController 为了保持 CSS 风格一致,需要明确的layout声明。

module Spree
  module Admin
    class TutorialsController < Spree::BaseController
      layout 'spree/layouts/admin'
      def index; end
    end
  end
end
