I’m trying to use the REST API that’s mentioned in the Tracks documentation. When I try one of the curl examples, I get a 500 error. I’m not sure where I should be looking in the logs to find the actual problem.

Request:

curl -u test-user:XXX -H "Content-Type: text/xml" -d "<project>New Project</project>" http://tracks.coxian.org/projects.xml -i 

Response:

HTTP/1.1 500 Internal Server Error
Date: Sat, 20 Nov 2010 16:39:52 GMT
Server: Mongrel 1.1.5

Any help would be greatly appreciated!

could you look in the tracks log in /path/to/tracks/log/production.log for the error?

Good shout, I couldn’t find the log file before (because I’m a noob). I’ve had a look at the logfile and I’m getting a “undefined method `stringify_keys!’ for “New Project”:String”

Fulls stack below - any ideas?

AFAICS, the xml you supply in the curl command is not complete. In this case you need to put the name of the project between <name> tag, like <name>test</name></project>

Ah yes! Of course thank you so much - I’m such an idiot - don’t know how I missed that.

Thanks again it’s working now.
