Question

I am trying to do webservice calls with django views using Amara library.

However anytime I do import amara (by simply importing it!) and call a django view with it imported, I get such errors:

Environment:

Request Method: GET
Request URL: http://127.0.0.1:4444/test
Django Version: 1.2.1

 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.sites',
 'django.contrib.messages',

 'django_extensions']
Installed Middleware:

Exception Type: TypeError at /test
Exception Value: argument must have 'write' attribute

How can this be solved ? I tried this under either Debian Lenny & Ubuntu 10.04 yet via Django SVN version and Amara 1

I am suspicious of some character encoding problem.

Putting “WSGIRestrictStdout Off” to my apache fixed the issue as said in here.
