Rails - 使用没有 STI 的类型列? [英] Rails -- use type column without STI?
问题描述
我想在不调用单表继承 (STI) 的情况下使用名为 type
的列 - 我只希望 type
成为包含 String 的普通列
.
I want to use a column called type
without invoking Single Table Inheritance (STI) - I just want type
to be a normal column that holds a String
.
如何在 Rails 不期望我具有单表继承并抛出异常的情况下执行此操作保留用于在继承的情况下存储类.?
How can I do this without having Rails expecting me to have single table inheritance and throwing an exception of The single-table inheritance mechanism failed to locate the subclass...This error is raised because the column 'type' is reserved for storing the class in case of inheritance.
?
关于如何做到这一点的任何想法?
Any ideas on how to do this?
推荐答案
在 Rails 3.1 中 set_inheritance_column
已被弃用,您也可以只使用 nil
作为名称,像这样:
In Rails 3.1 set_inheritance_column
is deprecated, also you can just use nil
as a name, like this:
class Pancakes < ActiveRecord::Base
self.inheritance_column = nil
#...
end
