可以通过命令行为表更改自动编写Rails迁移吗?

例子:

ruby script/generate migration renamePostsTableToActicles

生成:

class RenamePostsTableToActicles < ActiveRecord:Migration
  def self.up
    rename_table :posts, :articles
  end
  def self.down
    rename_table :articles, :posts
  end
end

比如:

ruby script/generate migration addCategoryIdToPosts category_id:integer
