[英]Ruby: Declarative_authorization polymorphic associations
I have two models (Item and Theme). 我有两个模型(项目和主题)。 They are both owned by a third model Users with a has_many association (User has many Themes and Items).
它们都归第三个模型所有,具有has_many关联的用户(用户拥有许多主题和项目)。 Both Item and Theme have_many :images.
项目和主题都具有多种:图像。
The Image model is a polymorphic association so the table has the columns imageable_id and imageable_type. Image模型是一个多态关联,因此该表的列为imageable_id和imageable_type。 If I had both an Item with ID 1 and a Theme with ID 1 the table would look like
如果我同时拥有ID为1的Item和ID为1的Theme,则该表将如下所示
id imageable_id imageable_type
------------------------------------
1 1 Item
2 1 Theme
I'm using declarative_authorization to re-write the SQL queries of my database to keep users from accessing items outside their account. 我正在使用declarative_authorization来重写我的数据库的SQL查询,以防止用户访问其帐户外的项目。 I'd like to write an authorization rule that will allow a user to read an image only if they can read the item they own.
我想编写一个授权规则,允许用户只有在他们可以阅读他们拥有的项目时才能阅读图像。 I can't seem to get the correct syntax (perhaps it's not supported):
我似乎无法获得正确的语法(也许它不受支持):
has_permission_on [:images], :to => [:manage], :join_as => :and do
if_attribute :imageable => is { "Item" }
if_permitted_to :manage, :items # Somehow I need to tell declarative_auth to imageable_id is an item_id in this case.
end
Then I'd have another rule mimicking the above but for themes: 然后我会有另一个模仿上述但主题的规则:
has_permission_on [:images], :to => [:manage], :join_as => :and do
if_attribute :imageable => is { "Theme" }
if_permitted_to :manage, :themes # Somehow I need to tell declarative_auth to imageable_id is a theme_id in this case.
end
Any ideas? 有任何想法吗? Thanks in advance!
提前致谢!
It seems that you commit a mistake in has_permission_on
method 看来你在
has_permission_on
方法中犯了一个错误
As I checked over has_permission_on and if_attribute 当我查看has_permission_on和if_attribute时
has_permission_on(:images, :to => :manage, :join_as => :and) do
if_attribute :imageable => "Item"
if_permitted_to :manage, :items
end
Hope this Help You !!! 希望这能帮到你!!!
