TemplateSyntaxError: service

Can somebody help me? Thanks

[Rob Cresswell (robcresswell-deactivatedaccount)]

This doesn't appear in master. Are you running any customisations? Are you services all intact?

[yangyide (yangyide01)]

It's cinderclient bug . I fixed class Service in python-cinderclient/cinderclient/v2/services.py .It works .

[yangyide (yangyide01)]

Thank you . <br/>It's cinderclient bug . I fixed method __repr__ in class Service in python-cinderclient/cinderclient/v2/services.py .It works .

[Paulo Matias (paulo-matias)]

Bug confirmed in stable/mitaka.

In openstack_dashboard.dashboards.admin.info.tabs.CinderServicesTab.get_cinder_services_data, cinder.service_list gets called (admin/info/tabs.py, line 74) and returns a list of cinderclient.v2.services.Service objects which do not contain a "service" attribute, as would be expected by the Service.__repr__ method.

Just for the sake of testing, if the "service" attribute is added to each Service object before the get_cinder_services_data method returns (for s in services: s.service = 'cinder'), the bug ceases to occur.

Looking at python-cinderclient code, I did not spot any place where the "service" attribute would have been set, which led me to believe the root issue is not in horizon, but in python-cinderclient, as yangyide suggested.

I believe the correct way to fix this bug would be to change python-cinderclient and make Service.__repr__ refer to self._info instead of self.service, just as it is done in python-heatclient, python-keystoneclient, etc.

The same goes for v3/services.py in master.

I am not sure if this is the correct procedure for informing the python-cinderclient project about the issue, but I will mark this issue as "also affecting" python-cinderclient.

I did not try to reproduce the bug with master, but I did not spot any code changes in the relevant files (from stable/mitaka to master) which would cause this issue to be fixed.

Ah, excuse my Jira tag :) I can't edit my comment.

[Paulo Matias (paulo-matias)]

Fixed in master. Not sure if it is still affecting stable/mitaka.

[Andrew Balfour (andrew-balfour)]

I'm slightly confused; the previous note states this was fixed in master, but the master as of Aug. 20 2016 shows it's still _service :

https://github.com/openstack/python-cinderclient/blob/master/cinderclient/v3/services.py#L26

so is this fixed in master, or was it fixed somewhere else?

[Sean McGinnis (sean-mcginnis)]

Fixed in python-cinderclient with https://review.openstack.org/#/c/331596/

[Gary W. Smith (gary-w-smith)]

As indicated above, the python-cinderclient was updated. It does not appear to have been a horizon problem.
