Rails - May 2012 - create a model/migration from an object that is returned from a gem that i installed

I am using the fog gem.

The fog gem has been added to my Gemfile

I would like to store the Fog object in my own database/model/
migration.

I tried to create the model like so, as I would usually create a
model, but using the Fog data type:




[tago@DevServer my]$ rails generate model fogaws fogobject:Fog
      invoke  active_record
      create    db/migrate/20120530114756_create_fogaws.rb
      create    app/models/fogaws.rb
      invoke    test_unit
      create      test/unit/fogaws_test.rb
      create      test/fixtures/fogaws.yml




However when I try the rake db:migrate I get this show stopper:




==  CreateFogaws: migrating
==================================================-- create_table(:fogaws)
rake aborted!
An error has occurred, this and all later migrations canceled:

undefined method `Fog'' for
#<ActiveRecord::ConnectionAdapters::TableDefinition:0x7fb3bc773798>






Here is what a Fog object can look like:
>> server = connection.servers.create
  <Fog::Compute::AWS::Server
    id="i-0984916f",
    ami_launch_index=0,
    availability_zone="us-east-1c",
    block_device_mapping=[],
    client_token=nil,
    dns_name=nil,
    groups=["default"],
    flavor_id="t1.micro",
    image_id="ami-3202f25b",
    kernel_id="aki-427d952b",
    key_name=nil,
    created_at=Wed May 30 00:50:41 UTC 2012,
    monitoring=false,
    placement_group=nil,
    platform=nil,
    product_codes=[],
    private_dns_name=nil,
    private_ip_address=nil,
    public_ip_address=nil,
    ramdisk_id=nil,
    reason=nil,
    root_device_name=nil,
    root_device_type="ebs",
    security_group_ids=nil,
    state="pending",
    state_reason=nil,
    subnet_id=nil,
    tenancy="default",

    user_data=nil,
    vpc_id=nil

I don''t know anything about Fog, but if you know what should be in the
table schema then you could just write the migration by hand.
