Rails ERD定制

Question

您能帮助我使用自定义选项 of Rails ERD生成一个显示主键和时间戳属性的图表吗？

我怎么把这个写进irb终端？这就是我试过的：

$ rake erd primary_keys, timestamps

GitHub列出了自定义选项，但我不了解如何编写属性。

attributes             <type,...> | false

  Specifies which attributes to include in the diagram output. This can be any   
  combination of the following attribute types:

  foreign_keys  any foreign key column in use for associations
  primary_keys  the primary key column (typically id)
  timestamps    any of the 'magic' timestamp columns (created_at/on,updated_at/on)
  inheritance   the single table inheritance column (typically type)
  *content       all other columns
  *To hide attributes altogether, set this option to false. Default value: content

谢谢。

我想应该是rake erd attributes=primary_keys,timestamps。
