Client repr hosts list return value will raise AttributeError: host

[Chung Chih, Hung]

When I am using python console to request hosts list
I import novaclient and initialize it.
Then using it to request hosts list.
But I got exception,
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "/usr/local/lib/python2.7/dist-packages/novaclient/v2/hosts.py", line 24, in __repr__
   return "<Host: %s>" % self.host
 File "/usr/local/lib/python2.7/dist-packages/novaclient/openstack/common/apiclient/base.py", line 494, in __getattr__
   raise AttributeError(k)
If I call get to request one host, it will not raise exception

I had attach sample code in attachment

Why it happen?
hosts list will try to request all host to following api
172.22.118.20:8774/v2.1/6446ba0419bf443c84b1b0ba2044b3e8/os-hosts
And response
{"hosts": [{"zone": "internal", "host_name": "controller", "service": "conductor"}, {"zone": "internal", "host_name": "controller", "service": "cert"}, {"zone": "internal", "host_name": "controller", "service": "scheduler"}, {"zone": "internal", "host_name": "controller", "service": "consoleauth"}, {"zone": "nova", "host_name": "compute1", "service": "compute"}, {"zone": "nova", "host_name": "compute2", "service": "compute"}]}

host get will send reqeust to following api
172.22.118.20:8774/v2.1/6446ba0419bf443c84b1b0ba2044b3e8/os-hosts/compute1
{"host": [{"resource": {"project": "(total)", "memory_mb": 7985, "host": "compute2", "cpu": 4, "disk_gb": 39}}, {"resource": {"project": "(used_now)", "memory_mb": 512, "host": "compute2", "cpu": 0, "disk_gb": 0}}, {"resource": {"project": "(used_max)", "memory_mb": 0, "host": "compute2", "cpu": 0, "disk_gb": 0}}]}

We can observe that get api's return value will contain host key name but list api's return value is host_name.
