Hammer CLI

After several hours of debugging and trying to understand the many components involved in the hammer cli (apipiebindings anyone?) I'm raising this issue because I'm getting the feeling that this might be a bug.

We're running foreman 1.8.0 RC2 and I'm trying to create a new (vmware virtual machine) host with the hammer CLI:

# hammer -v -d host create \
    --hostgroup-id=2 \
    --compute-resource-id=1 \
    --compute-profile-id=1 \
    --environment-id=3 \
    --compute-attributes="cluster=<CLUSTER-NAME>" \
    --volume="datastore=<DATASTORE-NAME>,size_gb=7" \
    --interface="network=<NETWORK-NAME>" \
    --name="hammer01" 

which runs and fails like this:

So I tried specifying --interfaces-attributes (although it's not required or documented anywhere AFAICT) and set it to some arbitrary networking parameters:

# hammer -v -d host create \
    --hostgroup-id=2 \
    --compute-resource-id=1 \
    --compute-profile-id=1 \
    --environment-id=3 \
    --compute-attributes="cluster=<CLUSTER-NAME>" \
    --volume="datastore=<DATASTORE-NAME>,size_gb=7" \
    --interface="network=<NETWORK-NAME>" \
    --interfaces-attributes="mac=FF:FF:FF:FF:FF:FF" \
    --name="hammer01" 

which leads to the following error:

500 Internal Server Error
{
    "error" => {
        "message" => "can't convert Symbol into Integer" 
    }
}
[ERROR 2015-04-09T15:43:48 Exception] can't convert Symbol into Integer
Could not create the host:
  can't convert Symbol into Integer

Now, what am I doing wrong? What's the correct set of command line options necessary to make this work? ;-)

Thanks!
