Posting xml to create new record

Hello,

I noticed that with the latest version of Rails, scaffolding in the
controller already has resourceful methods.  Based on the comments in
the code, it seems that all of this is built in, but I''m having some
trouble with creating new records by posting xml data.

I have a SubversionRepository model and SubversionRepositories
controller.  When I access /subversion_repositories.xml I get a list of
repositories in a format like:

<?xml version="1.0" encoding="UTF-8"?>
<subversion-repositories type="array">
  <subversion-repository>
    ...
    <name>repo1</name>
    <group>group1</group>
  </subversion-repository>
  <subversion-repository>
    ...
  </subversion-repository>
</subversion-repositories>

Based on this format, I tried posting a new repository to the address
/subversion_repositories.xml using the following xml.

<subversion-repository>
  <name>newrepo</name>
  <group>newgroup</group>
</subversion-repository>

I store this in the file repo.xml and post it using the following code.

require ''net/http''
require ''uri''
require ''rexml/document''

file = File.new "repo.xml"
xml_document = REXML::Document.new(file)

puts "sending XML in http POST"
http_client = Net::HTTP.new(''localhost'', 3000)
http_result = http_client.post(''/subversion_repositories.xml'',
xml_document.to_s)
puts "result type: " + http_result.class.name
puts "result: " + http_result.body.to_s


The script returns the following output.

sending XML in http POST
result type: Net::HTTPClientError
result: <?xml version="1.0" encoding="UTF-8"?>
<errors>
  <error>Name can''t be blank</error>
  <error>Group can''t be blank</error>
</errors>

The log file has an entry similar to the following.

Processing SubversionRepositoriesController#create (for XXXXX at
2008-03-13 14:54:00) [POST]
  Session ID: XXXXX
  Parameters: {"format"=>"xml",
"action"=>"create",
"controller"=>"subversion_repositories",
"<subversion-repository>\n
<name>newrepo</name>\n    <group>newgroup</group>\n   
<created-at
type"=>"''datetime''
nil=''true''/>\n    <updated-at
type=''datetime''>2008-03-12T16:15:51-05:00</updated-at>\n
</subversion-repository>"}
Completed in 0.01600 (62 reqs/sec) | Rendering: 0.00000 (0%) | DB:
0.00000 (0%) | 422 Unprocessable Entity
[http://localhost/subversion_repositories.xml]

Does anyone know what I''m doing wrong?  Does this functionality not
come
built in?

Thanks for your help.
Justin

Re: Posting xml to create new record

Have you tried
headers = {''Content-Type'' => ''text/xml''}
http_result = http_client.post(''/subversion_repositories.xml'',
xml_document.to_s,headers)
