using python-cloudant to connect to couchDB

[Ramanadham, Radhika]

Hi guys,
I have a dumb question.

Now with cloudant, how do I connect to my couchDB server (http://localhost:5984) with no username and password?

All the examples I see connect to cloudant and not couchDB. How do I connect to http://127.0.0.1:5984/

import cloudant

# connect to your account
# in this case, https://garbados.cloudant.com
USERNAME = 'garbados'
account = cloudant.Account(USERNAME, async=True)

# login, so we can make changes
future = account.login(USERNAME, PASSWORD)
# block until we get the response body
login = future.result()
assert login.status_code == 200

Thanks,
Radhika

The library exists to connect you to cloudant, which is a remote service. :)

Call account with the uri key word variable:

Account(uri="http://localhost:5984")

While this is true, it also works plenty well to connect to any
couchdb instance. We've switched to using it and I've found the
interface somewhat better (cleaner?) in comparison to other similar
modules.

Of course a matter of taste.

But, I see they say its an interface for cloudant or couchDB



https://pypi.python.org/pypi/cloudant/0.5.6

Absolutely, see my last email about passing the uri to Account.

The statement says that this is interface for Cloudant who are using
CouchDB. So you can query CouchDB databases hosted at Cloudant. You can't
use this interface for a local CouchDB database.

Please have a look at http://couchdbkit.org/ and
https://code.google.com/p/couchdb-python

Cheers

This is completely incorrect. We use this module to connect to our
local couchdb databases.

Here is a gist demonstrating using the cloudant module connecting to a
local couchdb:

Mike, Radhika,

well - obviously I am wrong. I am sorry. Thanks for your example Mike. I
think Radhikas question is very well answered then :)

But I am still wondering if the intention of this library is to use it for
Apache CouchDB's and not only Cloudant. But on the other side if it works
it works ...

Cheers

Andy

[Ramanadham, Radhika]

Thank you very much for the example.
My intention is to use it only for my local couchdb.

[Ramanadham, Radhika]

No problem. Thanks for responding.
Yes, my intention is to only use it for local couchDB and create db, documents and perform CRUD ops.

No problem, I probably should've sent the gist link with my first
response to avoid confusion. :-)

I thought so to, initially. Certainly the name suggests this!
However, I don't think there are any features (yet?) that are
cloudant-API specific. I may be wrong about this.

Biggest differences I've found in comparison to the more well known
modules you listed is the built in async behavior and the avoidance of
anything to do with document schemes. (It's quite a bit more
lightweight.) It's not the only "other" module to do this; there's an
open discussion concerning this on the GitHub page:

https://github.com/cloudant-labs/cloudant-python/issues/25

Cheers,
Mike

The biggest difference is the Cloudant module supports our search interface. I think Max's aim is to make it work for CouchDB as much as possible but where api's diverge get Cloudant support done first. For things like document and database crud you should be fine. I think Radhikas use case would be well supported.
Cheers

Hi everyone,

is anyone willing to write some notes

here: https://cwiki.apache.org/confluence/display/COUCHDB/Python

There could be added some info below or in a box :)

You need to create an account. If done so, please drop me a note and I'll
add you to the CouchDB space.

Thanks

Cheers

Hi,

I have couchdb running on linux box.

SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 3

Python version is 3.3 and have python-cloudant (cloudant-0.5.6) module installed.

Now when I try to run my code, it fails with the error-

File "./first.py", line 2, in <module>
import cloudant
File "/usr/lib/python3.3/site-packages/cloudant-0.5.6-py3.3.egg/cloudant/__init__.py", line 1, in <module>
ImportError: cannot import name Resource

My code works great on a windows box. I am now having issues with running any py script because of the above error. Can anyone please help?

Thanks,
Radhika

That should be fixed in 0.5.7+ try to update.

Hi Radhika,

This type of error would be probably be best reported directly to the
cloudant-python developers. I would suggest opening up an issue here:

https://github.com/cloudant-labs/cloudant-python/issues

I have found them to be pretty responsive.

Cheers,
Mike
