Hi,
I am trying to convert a hash to JSON using ActiveSupports built in
.to_json. I am doing similar to the example below but are there
certain strings that could go in place of ''bar'' or
''rez'' that will
break the to_json method? I am using a very long string from rjs
output in place of ''bar''.
Perhaps .to_json is not ready yet?
Thanks,
Peter
def MyController < ApplicationController
def give_me_json
# make sure not to send html but text/plain
@headers["Content-Type"] = "text/plain; charset=utf-8"
data = { :foo => ''bar'', :etc =>
''rez'' }
render_text data.to_json
end
end

If so, it might be that your controller-file isn''t in utf-8 itself, or that it''s not stored as utf-8 in the database (in case you grab the data from there). I''ve been using the to_json function a bit myself and it seems to work properly on everything I''ve tried (once I got everything utf-8 encoded so it worked with the Swedish characters I tossed at it). Hope that helps, Mathias.

I now doubt any problems are with ActiveSupport''s JSON support. I found a nice solution using XML and may look back at this problem in the future. Thanks to those that read. Peter

But since JSON is just an object notation, Prototype would create an object, assign it to nothing and nothing would happen. It''s my guess. Peter

Partly I asked because I wasn''t sure if anyone used the .to_json from ActiveSupport yet. In the online docs I don''t see anything so I wasn''t sure if it was ready. Since you use it successfully I thought a little harder and I think I was the problem, of course. Thanks Peter
