Hi there,
I am fairly new to the Rails framework, so forgive me if there is an
obvious solution to this problem.
I am using Rails 2.1.0 and trying to jsonify a hash containing an
array. E.g.
result = { :name => "McLovin", :attachments =>
[''file.pdf'',
''file.jpg''] }
=> {:attachments=>["file.pdf", "file.jpg"],
:name=>"McLovin"}
result.to_json
I would expect something like:
{
"name": "McLovin",
"attachments": [
"file.pdf",
"file.jpg"
]
}
But instead I get:
TypeError: wrong argument type Hash (expected Data)
from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/
active_support/json/encoding.rb:21:in `to_json''
from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/
active_support/json/encoding.rb:21:in `send''
from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/
active_support/json/encoding.rb:21:in `encode''

active_support/json/encoding.rb:31:in `raise_on_circular_reference''
from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/
active_support/json/encoding.rb:20:in `encode''
from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/
active_support/json/encoders/hash.rb:42:in `to_json''
from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/
active_support/json/encoders/hash.rb:41:in `map''
from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/
active_support/json/encoders/hash.rb:41:in `to_json''
from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/
active_support/core_ext/object/misc.rb:28:in `returning''
from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/
active_support/json/encoders/hash.rb:40:in `to_json''
from (irb):54
If I do "result.to_json( :except => :attachments )", then it works.
Best regards, Mads Kristiansen

Okay, thanks. Just wanted to confirm that it actually worked somewhere.. :) I removed the "json_pure" gem and now it works for me too.. Not sure if that will cause other problems, but we''ll see about that.

This is also a problem in Merb. I believe AR''s json and Merb''s json don''t play well together. I put this in init.rb and now life is grand.
