Hi,
I'm trying to get a user's list of permissions, i.e., list all permissions a user have on VMs and VmPools.
In SDK3 that was easy as I could run (being 'u' a User object):
for perm in u.permissions.list(): vm = perm.get_vm() vmpool = perm.get_vmpool()
if vm or vmpool: print "User has some permissions!"
In SDK4 I cannot reproduce the same logic. u.permissions returns an empty list ([]).
What I have so far is something like this:
for u in users_serv.list(): if u.user_name == 'admin@internal': continue
vms_service = sys_serv.vms_service() for vm in vms_service.list(): vms = vms_service.vm_service(id=vm.id) ps = vms.permissions_service() for perm in ps.list(): perm_service = ps.permission_service(id=perm.id) getperm = perm_service.get() if getperm.user.user_name == u.user_name: print "Permission for %s" % (u.user_name) if getperm.vm: print "VM: %s" % (getperm.vm.id) if getperm.vm_pool: print "VmPool: %s" % (getperm.vm_pool.id)
However, this seems a bit overkill. We have nearly 850 VMs and for a single user this takes about 25 minutes to run. Additionally, it doesn't seem to return any permission, although I know this user has some permissions over 2 VMs (not sure where is it messed up).
I also tried using the system_service.permissions_service() but it seems to return only the global permissions.
Is there an easier way to do this?
Thanks!
Version 4 of the SDK makes a clear distinction between what are pure containers of data (like the User class) and what are services (like the UsersService class). Therefore when you call 'u.permissions' in version 4 of the SD you get nothing, because the object that you retrieved previously doesn't contain the permissions, only a link. That is exactly how the API behaves. When you do this:
GET /ovirt-engine/api/users/{user:id}
You only get the data of the user, and some links to other related data, like the permissions:
<user id="..." href="..."> <name>myuser</name> ... <link rel="permissions" href="/ovirt-engine/api/users/{user:id}/permissions"/> </user>
In version 4 of the SDK the simple way to follow the link is to use the Connection.follow_link method. So, you need something like this:
---8<--- # Find the user: users_service = connection.system_service().users_service() user = users_service.list(search='name=myuser')[0]
# Follow the link to the permissions of the user: perms = connection.follow_link(user.permissions) for perm in perms: if perm.vm or perm.vm_pool: print "User has some permissions!" --->8---
Thanks, that makes things much easier! Regards, Nicolás
