record is displayed:

Art
Art(id: integer, name: string, created_at: datetime, updated_at:

e.g.

Author
=> Authorid: integer, first_name: string, last_name: string, dob:
date, created_at: datetime, updated_at: datetime, genre: string
Author.inspect
=> “Author(id: integer, first_name: string, last_name: string, dob:
date, created_at: datetime, updated_at: datetime, genre: string)”

Thanks for your replies.

Using columns, the name can be queried by human_name:

Art.columns[0].human_name

inspect is perfect for displaying purposes.

Note that, in my experience at least, this is rarely necessary unless
you’re writing something like ActiveScaffold. What are you trying for
here?
