knex迁移创建外键

Question

我尝试了链接中的代码来创建FK：

how to do knex.js migration

我在网上收到了错误：

table.bigInteger('AddressId').unsigned().index().inTable('Address').references('id');

错误：

这可能会有点晚，但错误是因为

table.bigInteger('AddressId').unsigned().index().inTable('Address').references('id');

应该写

table.bigInteger('AddressId').unsigned().index().references('id').inTable('Address')

inTable函数仅在调用引用后才存在，如文档http://knexjs.org/#Schema-inTable

中所述

  

设置＆＃34;表＆＃34;调用后外键列所在的位置   column.references。
