Question

I’m building an application in Python2.6 that needs to get data from CouchDb. I’m using CouchDB-0.8-py2.6 to connect to the database.
I’m using this code:

import couchdb
server = couchdb.Server(url='http://localhost:5984/', full_commit=True, session=None)
db = server['databaseName']
doc = db['docId']
value = doc['value']
print(value)

On my local machine (OSX) the code runs perfectly, but when I’m trying to run it on a Debian server, I get the following error:

File "/usr/local/lib/python2.6/dist-packages/CouchDB-0.7dev_r199-py2.6.egg/couchdb/client.py", line 165, in __getitem__
   db.resource.head() # actually make a request to the database
 File "/usr/local/lib/python2.6/dist-packages/CouchDB-0.7dev_r199-py2.6.egg/couchdb/client.py", line 977, in head
   return self._request('HEAD', path, headers=headers, **params)
 File "/usr/local/lib/python2.6/dist-packages/CouchDB-0.7dev_r199-py2.6.egg/couchdb/client.py", line 1010, in _request
   resp, data = _make_request()
 File "/usr/local/lib/python2.6/dist-packages/CouchDB-0.7dev_r199-py2.6.egg/couchdb/client.py", line 1005, in _make_request
   body=body, headers=headers)
 File "/usr/local/lib/python2.6/dist-packages/httplib2-0.6.0-py2.6.egg/httplib2/__init__.py", line 1025, in request
   cached_value = self.cache.get(cachekey)
AttributeError: 'bool' object has no attribute 'get'

I’ve tried to Google this numerous times and no-one seems to have the same error. Does anyone have an idea what I’m doing wrong here?

Answer 1

You’re using a different version of CouchDB on the server – CouchDB-0.7dev_r199. CouchDB does not use httplib2 anymore, so if you get your development and server environments roughly the same the problem is quite likely to disappear.
