Cisco plugin cannot find argument action_prefix

[Harsh Prasad]

While using the Cisco plugin, this is the error received when running cisco's cli command list_extensions:

harspras@harspras-ThinkPad-T400:~/openstack/quantum$ python quantum/plugins/cisco/client/cli.py list_extensions
Traceback (most recent call last):
  File "quantum/plugins/cisco/client/cli.py", line 218, in <module>

    action_prefix=ACTION_PREFIX_EXT, tenant="dummy")
TypeError: __init__() got an unexpected keyword argument 'action_prefix'
harspras@harspras-ThinkPad-T400:~/openstack/quantum$

I have commented the UCS and NEXUS plugins and inventory line in cisco_plugins.ini file to run without UCS and NEXUS.
Also, the HOST and PORT defined in quantum/plugins/cisco/client/cli.py is not global and is not found by 'Client' from 'quantumclient'.

Please tell me what is to be donequantum/plugins/cisco/client/cli.py

This is not a plugin error, its a regression in the library for extensions. More information/fix coming to .

[Harsh Prasad (prasad-tanay)]

Ok. So is there any way to use cisco plugin without UCS or Nexus for testing the extensions or Core API?

[Sumit Naiksatam (snaiksat)]

Yes, you can use a REST client like the one available in Firefox:

In my earlier response I meant to say that the problem is with the "client" library being used to access the extensions. Looking at fixing it.

[Harsh Prasad (prasad-tanay)]

Oh.. Cool.. Will check that out. And btw i ran it successfully by making few minor changes to quantum/plugins/cisco/client/cli.py and quantumclient/__init__.py.

Changes made are as following:

to quantum/plugins/cisco/client/cli.py in def main(): + global HOST
                                                                                                + global PORT
                                                                                                + global USE_SSL

to quantumclient/__init__.py in def __init__() of class Client:

+ action_prefix="/v1.1/tenants/{tenant_id}", ## In the arguments of __init__()
+ self.action_prefix = action_prefix#"/v%s%s" % (version, uri_prefix)

After these changes, the cisco client was working. Do tell if such changes should not be made.

[Sumit Naiksatam (snaiksat)]

Harsh, thats great to hear that you were able to make it work with those changes, well done!

The variable definition changes are good. The changes to the quantumclient are also good for this particular case, however, we ideally want to make changes only to cli.py for getting this to work. One way to do it would be to change action_prefix in the cli.py to uri_prefix. I was running into some other problems after doing that, hence did not commit it right away.

[Harsh Prasad (prasad-tanay)]

Ok. I will then make changes to only quantum/plugins/cisco/client/cli.py. What I'll do is that i will add version and uri_prefix instead of action_prefix and the default __init__.py will gather the information correspondingly. Will let you know how it works. And if it looks fine then i will commit the changes.

Hey, was trying to commit a draft but i was getting an error of cannot create new references. So i tried changing the assignee, but no luck. So i had to submit a final review and not a draft.

[Sumit Naiksatam (snaiksat)]

Assigned this to you, so you should be good now. Thanks!
