Hi
When I fix some bugs, I found that some code in
nova/compute/api.py
sometimes we use db ,sometimes we use objects.... do we have any
criteria for it? I knew we can't access db in compute layer code, how about
others ? prefer object or db direct access? thanks
def service_delete(self, context, service_id):
"""Deletes the specified service."""
objects.Service.get_by_id(context, service_id).destroy()
def instance_get_all_by_host(self, context, host_name):
"""Return all instances on the given host."""
return self.db.instance_get_all_by_host(context, host_name)
def compute_node_get_all(self, context):
return self.db.compute_node_get_all(context)
Best Regards!
