数据库迁移文件如下
class CreateWorks < ActiveRecord::Migration def change create_table :works do |t| t.integer :project_id t.integer :user_id t.datetime :datetimeperformed t.decimal :hours, percision: 5, scale: 2 t.timestamps null: false end end end
执行:
rake db:migrate
报错
Error adding decimal column: precision cannot be empty if scale is specified
不知道是什么原因,请帮忙看一下,谢谢!
已解决,precision拼写错误!
