It might help to explain the model in words for those who are not too
familiar with DC internals; in particular, it might not be obvious what
relationships the various classes have (since we do not express that in
our models)
Just to restate what's in the model code (patch 1/3), the model seems to
be (in some pseudo-AR notation):
class Network
string :name
string :address_block
enum :state # What values are allowed ?
has_many :subnets
has_many :ports # Can you attach a port to a network
directly ?
end
class Subnet
string :name
enum :state # What values are allowed ?
enum :type # What values are allowed ?
string :address_block
belongs_to :network
has_many :ports
end
class Port
string :name
string :attachment
string :mac_address
string :ip_address
enum :state
enum :type
belongs_to :network # Do we get a network or subnet here or
both ?
end
There are various questions about the code I have based on the above but
it might best to make sure we all understand what the model is supposed
to be and go from there. In particular, in the above, we need to explain
what the possible values for the various enums are, and I am not clear
on whether a subnet can be used in various places where the code expects
a network (e.g., when creating a port)
