[Bug 1593652] Re: When created subnet for a network failed, it seems that error info returned by neutronclient didn't return network and subnet info
It seems to me that the problem is with how Horizon is reporting the
error. The python-neutronclient will not return a subnet_id as no subnet
is created. It could be changed to return the network_id, but seeing as
that is included in the subnet-create request I'm not sure it's
necessary.
** Changed in: neutron
Status: New => Invalid

Title:
When created subnet for a network failed,it seems that error info
returned by neutronclient didn't return network and subnet info
Status in neutron:
Invalid
Bug description:
Created subnet associated with subnetpool_1 for a network,through
Horizon Web,creating another subnet associated with subnetpool_2
returned error info as follows:
Error: Failed to create subnet "" for network "None": Subnets hosted
on the same network must be allocated from the same subnet pool.
Neutron server returns request_ids: ['req-
cad13014-6fe6-4db4-99e6-750de19fbf85']
" subnet "" " and " network "None" " appeared in the error info above
is not friendly,it seems that neutronclient didn't return network and
subnet info caused this.
