由于我到目前为止完全无法破译的原因,我不再能够使用ActiveSupport :: HashWithIndifferentAccess了.
模型的相关部分如下所示:
class Item < ActiveRecord::Base
serialize :metadata, ActiveSupport::HashWithIndifferentAccess
(我添加了尝试强制它的选项,但它没有帮助.以前这一切都工作正常,我没有那里.)
只要对象在内存中,一切正常.这是正确的HashWithIndifferentAccess,生活是美好的.一旦它被保存到数据库,它就会被保存为Hash:
mysql> select * from items;

name: …我来自主要使用VIM的所有东西,所以我有一个习惯,基本上任何时候我打字输入.无论如何只有取消绑定自动完成菜单才能在逃脱时出现？如果我删除了esc的"取消"键绑定,那么它会停止弹出自动完成菜单,但我无法取消任何内容,而是每当我遇到逃生时我都会出现颠倒的问号.
