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

?> Category.findfirst).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.findfirst).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.findfirst)

or

?> y Category.findfirst)

or as rob pointed out:

?> puts Category.findfirst).to_yaml

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

?> Category.findfirst).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.
