Ambiguous "500 - INTERNAL SERVER ERROR" error

[Huuuze]

I'm not sure if this problem is with the REST interface or with my
code. When I run the code below, the Django web server issues a "500
- INTERNAL SERVER ERROR" error. Any thoughts?

import urllib, urllib2

URL = 'http://localhost:8000/ws/person/'
XML = {'person': '<?xml version="1.0" encoding="utf-8"?><django-
objects version="1.0"><object pk="" model="persons.person"></object></
django-objects>'}

request = urllib2.Request(URL, urllib.urlencode(XML))
request.add_header('User-Agent', 'Mozilla/5.0 (Windows; U; Windows NT
5.1; en-US; rv:1.8.1.12)')
urllib2.urlopen(request)

you can print the return into an html file and see what Django said:

response = urllib2.urlopen(request)
f=open("log.html","w+")
f.write(response.read())
f.close()

Then open the file with your browser and see the detailed message.
Perhaps setting DEBUG=True in your Django instance( if not already )
would help troubleshoot.

HTH,

PS : my guess is that you are missing a value for the "pk" field, but
it is just a guess

In this instance, the "file" code won't execute; the exception is
generated by the call to urlopen().

This code executes independent of Django. Its a client app that I
wrote to test out my connection to the Django REST Interface.

Since I'm only testing inserts (a.k.a., POSTs), I'm not sure how the
Django REST Interface handles new records. As such, I blanked out the
"pk" field since a new user should be issued a new ID based upon the
PK sequence.

OK...found part of the problem. This call in model_resource.py is
throwing an error:

>> Line 143: self.receiver.get_post_data(request)

It generates an error with the following message:

>> <unknown>:1:5: not well-formed (invalid token)

At this point, I'm at a loss. You can see that I'm calling
"urllib.urlencode()", so the data should encoded. I also printed out
the request and examined the data in the POST:

POST:<QueryDict: {u'person': [u'<?xml version="1.0" encoding="utf-8"?
><django-objects version="1.0"><object pk="8" model="persons.person"></
object></django-objects>']}>,

Anyone feedback on what may be causing this problem?

The exception is server side, and the return will contain whatever
html your server has sent back. If you have debug set on your django
instance , your server will tell you where that exception happened.

I figured it out. This call caused the 500 error:

>> urllib.urlencode(XML)

The REST interface didn't understand this request.POST value since it
was delivered as a key:value pair; the key in this instance was not
what the interface expected.

I am not sure if you have this solved, but what you are posting is not
well formed XML. Also, for the pk, i believe you need to put that as any
integer(i use 0), for the benefit of the deserializer, but don't worry
it will be neglected and the record given a new pk on insert.

I have corrected the problem and I am now using the wonderful REST
API. Thank you very much for your help!
