May i know how can i fix it ?

[Stéphane Albert (sheeprine)]

Hi,

Did you used an old devstack deployment? You might still have an old enable file in your enabled horizon directory.
Try to search a file named _90_enable_ck.py and delete it.

It should do the trick.

[maestropandy (maestropandy)]

hi,
 i did clone again to pull latest devstack.. successfully done it, later i have added cloudkitty entry in localrc file

# ceilometer
enable_plugin ceilometer https://git.openstack.org/openstack/ceilometer.git master

# horizon
enable_service horizon

# cloudkitty
enable_plugin cloudkitty https://github.com/openstack/cloudkitty master
enable_service ck-api ck-proc

while doing ./stack.sh getting error as

" ERROR cloudkitty AttributeError: 'NoneType' object has no attribute 'auth_url'
2015-10-26 19:07:54.512 25955 ERROR cloudkitty
ck-proc failed to start
"

please let me know how to fix it ?

[Stéphane Albert (sheeprine)]

I answered you on IRC but since other people might have the same issue I'll answer here too.
If you are using the same machine/VM, you will not solve the issue only pulling latest devstack version. The issue is caused by an old enabled file named _90_enable_ck.py, this file will not be removed by git or devstack. You need to remove it by hand.
To be sure that you have the latest version got to /opt/stack/cloudkitty-dashboard and do a git pull from here, do the same for /opt/stack/cloudkitty.

Tell me if it corrected your problem.

[maestropandy (maestropandy)]

Hi Stephan,

I have removed _90_enable_ck.py and did git pull from /opt/stack/cloudkittyfor latest version, now i could able to see horizon, but the "Rating" tab in horizon for billing is missing.

Cloud kitty CLI is working fine and service is running, please find the attached screenshot of horizon dashboard.

This issue was fixed in the openstack/cloudkitty-dashboard 0.5.0 release.
