推荐答案

尝试将文件重命名为 sample_data.rake.

Try renaming the file to sample_data.rake.

通过将您的代码放在 lib/tasks 中名为 testomatic.rake 的文件中，我能够让您的示例工作(用 p 语句替换任务的内部结构).

I was able to get your example working (replacing the internals of the task with a p statement) by putting your code in a file called testomatic.rake in lib/tasks.
