ruby-on-rails - Active Record JDBC Derby Adapter interpreting smallint columns as boolean

Question

I am using the activerecord-jdbcderby-adapter gem with jruby 1.7.9 and rails 4.0.2 with a legacy Derby database.

My Derby tables have several smallint fields.

These are all being interpreted by the adapter as boolean (i.e. the int value is lost).

Is there a workaround for this (other than changing the column types)?

目前不需要（到目前为止没有人需要它），但可以通过一些复制粘贴来完成，例如 Firebird 适配器（以及其他一些适配器）会发生这种情况：

所以需要在这里的某个地方添加类似的东西：

寻找公关 :)
