Rails console output shows "\n" rather than putting in new line? is there a way to change this?

Hi,
I note rails console shows “\n” rather than putting in new line? For
example:

?> Category.find(:first).to_yaml
=> “— !ruby/object:Category \nattributes: \n updated_at: 2009-01-20
03:39:22\n tax_item_id: \n category_type_id: “2”\n title: Investment\n
id:
“1”\n category_id: \n category_group_id: “5”\n created_at:
2009-01-20
03:39:22\n active: “0”\nattributes_cache: {}\n\n”

I note that if you “puts” the same thing from an Rspec test it formats
fine
(with new lines)

Question: Is there a way to change this for the console?

either:
puts Category.find(:first).to_yaml
or since irb saves the last expression into the variable _ (yes, an
underscore):
puts _

irb inspects the result, either don’t convert it to a string, or print
it.

?> Category.find(:first)

or

?> y Category.find(:first)

or as rob pointed out:

?> puts Category.find(:first).to_yaml

Usually I don’t care about all the fields, so I’ll do something like

?> Category.find(:first).title

and leave it at that.

Don’t rely on the console so much. Put puts in a unit test!

I rely heavily on the console, and also on unit tests. The two aren’t
in conflict or competition; they’re different tools. It’s important to
know how irb (in Rails console form or otherwise) works, and why it
produces the output it does.
