We''ve just upgraded our Rails 2.0.2 app to 2.3 and the webservices
create APIs are failing. Instead of receiving parsed XML, the
controller''s create method gets the whole xml as a hash key with the
value nil.
To isolate this issue, I generated a vanilla app:
$ rails scaffold_xml
$ ./script/generate scaffold project title:string description:text
$ rake db:migrate
In real life I test this with cucumber features, but for the purposes of
short repro steps, I added this to the top of projects_controller.rb
skip_before_filter :verify_authenticity_token
And then ran the POST for the create request on the command line
$ curl -X POST -d
''<project><title>Awesome</title><description>This
is
an awesome project.</description>''
http://localhost:3000/projects.xml
<?xml version="1.0" encoding="UTF-8"?>
<project>
<created-at
type="datetime">2009-06-21T14:09:08Z</created-at>
<description nil="true"></description>
<id type="integer">1</id>
<title nil="true"></title>
<updated-at
type="datetime">2009-06-21T14:09:08Z</updated-at>
</project>
The log says:
Processing ProjectsController#create to xml (for 127.0.0.1 at 2009-06-21
07:09:08) [POST]
Parameters:
{"<project><title>Awesome</title><description>This

awesome project.</description>"=>nil}
Project Create (10.4ms) INSERT INTO "projects"

Completed in 181ms (View: 134, DB: 10) | 201 Created

To test my assumptions, I repeated the above steps with "rails _2.0.2_
scaffold_xml_202" to look at it in the old version of rails (minus the
forgery bit which didn''t used to be required.) I must be missing
something basic here. Can anyone enlighten me or point me to relevant
docs?
Thanks,
Sarah

Having done that you need to get curl to set > the content type appropriately.Ah, so there must be a bug in my test. This works: $ curl -X POST -d ''<project><title>Awesome</title><description>This is an awesome project.</description></project>'' -H "Content-Type: application/xml" http://localhost:3000/projects.xml <?xml version="1.0" encoding="UTF-8"?> <project> <created-at type="datetime">2009-06-21T08:06:41-07:00</created-at> <description>This is an awesome project.</description> <id type="integer">3</id> <title>Awesome</title> <updated-at type="datetime">2009-06-21T08:06:41-07:00</updated-at> </project> Thanks Fred! -- Posted via http://www.ruby-forum.com/.

Thanks for your help, Fred. For future reference, I''ve written up a little cheat sheet with the various curl commands to access the various default Rails XML APIs: http://www.ultrasaurus.com/sarahblog/2009/06/simple-web-services-with-rails/ -- Posted via http://www.ruby-forum.com/.
