Fog and Openstack can't specify network by name

Question

I am trying out a new feature for chef called Chef-Metal and it uses Fog as the driver to connect to Openstack. I am having a lot of trouble getting the correct syntax to identify the network I want by name and not :net_id. This is what I have been playing with so far:

:nics => [
  {
    :network => 'net-shared-vlan-25'                     # Doesn't Work
    # :name => 'net-shared-vlan-25'                      # Original Test (didn't work)
    # :net_id => '84685c12-ce9b-4056-8dcb-bfa2283e97bf'  # Works! (but need name)
  }
]

The Error that I keep getting (cleaned up) is:

Expected([200, 202]) <=> Actual(500 InternalServerError)
response => #<Excon::Response:0x0000000421c830
@data = {
  :body => "{\"computeFault\": {\"message\": \"The server has either erred or is incapable of performing the requested operation.\", \"code\": 500}}",
  :headers => {"Content-Length"=>"128", "Content-Type"=>"application/json; charset=UTF-8", "X-Compute-Request-Id"=>"req-eb48b850-0449-4a02-ae96-f6374b047b37", "Date"=>"Tue, 01 Jul 2014 16:08:55 GMT"},
  :status => 500,
  :remote_ip => "10.129.10.250",
  :local_port => 54683,
  :local_address => "10.129.17.41"},
@body = "{\"computeFault\": {\"message\": \"The server has either erred or is incapable of performing the requested operation.\", \"code\": 500}}",
@headers = {"Content-Length"=>"128", "Content-Type"=>"application/json; charset=UTF-8", "X-Compute-Request-Id"=>"req-eb48b850-0449-4a02-ae96-f6374b047b37", "Date"=>"Tue, 01 Jul 2014 16:08:55 GMT"},
@status = 500,
@remote_ip = "10.129.10.250",
@local_port = 54683,
@local_address = "10.129.17.41">

If anyone knows the correct syntax that is needed to identify a network by name instead of ID in Openstack using Fog, your help would be greatly appreciated. Thanks.

Unfortunately, Chef Metal, and more accurately, the Fog gem, only allows you to specify a network by its id. The relevant code in Fog can be found here:

data['server']['networks'] = options[:networks] || [
  { :uuid => '00000000-0000-0000-0000-000000000000' },
  { :uuid => '11111111-1111-1111-1111-111111111111' }
]

Which is a little bit annoying, I understand.

But this is Open Source! You can always write a pull request for the Fog gem to look up the ID of the network from the name. And the great news is, if Fog supports it, then Chef Metal will!
