How to add values to self.to_json

Question

Right now, if I have a user object like @user.

I can do @user.to_json

What I want to do is add values to the json object rails creates. I've tried this:

@user.attributes.merge{ :catalyst_show => true }

But that errors with syntax error, unexpected tASSOC, expecting '}'

Any ideas on how you can add attributes to the json object?

thanks

Ruby thinks you're passing a block to `merge`, instead of the `Hash` you intended. So to make it clear to Ruby, you need to disambiguate - see Sameer's answer. — Zabba, Aug 05 '11 at 03:19

you need to add parenthesis. @user.attributes.merge({ :catalyst_show => true }) or @user.attributes.merge( :catalyst_show => true )

Omitting both, the `()` and the `{}` should also work in that case? – Zabba Aug 05 '11 at 03:18
