rails g migration"command"生成列重命名迁移？

Question

我想自动生成一个如下所示的迁移文件:

class RenameDatabaseColumn < ActiveRecord::Migration
  def change
    rename_column :events, :subcategory, :subcategory_id
  end
end

有没有办法格式化我的

rails g migration ~rename_column_events_subcategory_subcategory_id~

或类似的东西自动生成该文件？

Answer 1

不,没有用于"重命名"列的自动生成命令.

参考源代码.自动生成器只能理解"to","from","add","remove","join_table","create"
