rails Active Record 中的 attr_accessible [英] attr_accessible in rails Active Record
问题描述
当我使用 attr_accessible
指定我将公开模型中的哪些字段时,脚本/控制台也是如此吗?我的意思是我没有指定为 attr_accessible
的东西也不能通过控制台访问?
When I use the attr_accessible
to specify which fields from my Model I will expose, is it true for script/console as well? I mean something that I didn't specify as attr_accessible
won't be accessible as well through console ?
推荐答案
这仅适用于批量赋值.例如,如果您要在模型中设置 attr_protected :protected
:
This is only true for mass assignment. For instance, if you were to set attr_protected :protected
in your model:
>> Person.new(:protected => "test")
=> #<Person protected: nil>
相反,您可以使用 attr_accessible
将您想要的所有属性设置为可访问.
Conversely, you could set all attributes you want as accessible using attr_accessible
.
但是,以下仍然有效:
>> person = Person.new
=> #<Person protected: nil>
>> person.protected = "test"
=> #<Person protected: "test">
这与控制器、视图等中的行为相同.attr_protected
仅防止大量分配变量,主要来自表单等.
This is the same behaviour as in controllers, views, etc. attr_protected
only protects against mass assignment of variables, primarily from forms, etc.
