Ruby -> REST, part 2

RT Users

Back in February, user ‘toml at bitstatement’ (
Carbon60: Cloud Consulting - Services and Solutions) posted a
question about interfacing with RT from Ruby via REST. That thread is
archived here:Carbon60: Cloud Consulting - Services and Solutions

I am having a similar problem, but when I implemented the solution described
in that thread, RT still won’t accept the comment.

Request from my Ruby application (hostnames have been changed to protect the
innocent):

-----snip-----
POST /REST/1.0/ticket/5702/comment HTTP/1.1
Accept: application/xml
Content-Type: multipart/form-data; boundary=“905815”
Cookie: RT_SID_RTNAME.80=132575bdeee36284a05518c9b8080edf; path=/

Host: rthost.somewhere.com
Content-Length: 308

–905815
Content-Disposition: form-data;
name=“attachment.txt”; filename=“attachment.txt”
Content-Type: text/plain

test attachment content
–905815
Content-Disposition: form-data; name=“content”

Ticket: 5702
Action: comment
Text: Adding attachment(s).
Attachment: attachment.txt

–905815–
-----snip-----

And the response from RT:
-----snip-----
HTTP/1.1 200 OK
Server: Apache/2.2.3 (Unix) mod_ssl/2.2.3 OpenSSL/0.9.7f PHP/5.2.6
mod_perl/2.0.4 Perl/v5.8.6
Transfer-Encoding: chunked
Content-Type: text/plain; charset=utf-8

40
RT/3.8.1 400 Bad Request

No attachment for attachment.txt.

-----snip-----

I assume from the RT error message that it is parsing the “content” form
field, or else it wouldn’t know to look for the attachment.txt file, but I
can’t figure out what’s wrong. Anyone have any ideas?

Content-Disposition: form-data; name=“content”

Ticket: 5702
Action: comment
Text: Adding attachment(s).
Attachment: attachment.txt

Your form is wrong.

This is a different issue than what I had, but the results of that
exercise are a ruby library which has been open-sourced. You can make
your life a lot easier by installing and using rt-client from rubyforge.
“gem install rt-client” should do the trick, and then:

rt= RT_Client.new( :server => “https://your.rt-server.com/”,
:user => “rt_user”,
:pass => “rt_pass” )
rt.comment( :id => 5702,
:Text => “Adding attachment(s).”,
:Attachment => “attachment.txt” )

and the library will take care of all the gory details for you.
