如何使用Rails 2.1和MySQL定义BigInt主键? [英] How can I define a BigInt primary key with Rails 2.1 and MySQL?

问题描述

从Rails 2.1开始，如果您在迁移中定义了一个新列，其类型设置为:integer，而:limit设置为5或更大，则在MySQL数据库中实际创建的列将为BigInt类型.太完美了.

Since Rails 2.1, if you define a new column in a migration with the type set to :integer and the :limit set to 5 or more, the column actually created in your MySQL database will be of type BigInt. That's perfect.

但是我不知道如何使用BigInt主键创建表.

But I cannot figure out how to create a table with a BigInt primary key.

有任何线索吗?
