Pretty-printing (or otherwise) a hash in a view template

Rails
1

I have some text boxes into which i want to output the contents of some
hashes, in the nice readable way we all know and love. Can i use
pretty-print for this? As far as i can tell, pp only works to standard
output and can’t be used to create text.

Is there another way to nicely print out the contents of a hash?

thanks!

I actually found out how to do this from another post somewhere - you
can get the output of pp into a string with

text = PP.pp(myhash, “”)

The resultant string has any quotes inside it escaped out.

thanks

Give to_yaml a shot. It’s a very readable way to dump ruby objects.

That’s not what i’m after, though i agree that yaml is nice and
readable. thanks anyway. :slight_smile:

In addition to PP.pp(myhash, “”), btw, i discovered that myhash.inspect
also works.
