Machinist and habtm relationship

[Andrea Fazzi]

Hi all,

I'm very new to machinist and I'm trying to use it to setup an habtm
association between two ActiveRecord entities: IPAddress and Hostname.

My blueprints are:

Sham.address { |num| "192.168.178.#{num}" }
Sham.hostname { |num| "Hostname #{num}" }

IpAddress.blueprint { address }
Hostname.blueprint { hostname }

In order to setup an association between an hostname and three ip addresses
- following the example on the README - I tried to use an helper method:

def make_hostname_with_ips
Hostname.make do |hostname|
3.times { hostname.ips.make }
end
end

BTW, calling the method results in the following exception:

ActiveRecord::RecordNotFound: Couldn't find Ip with ID=1

I'm using machinist from git and ActiveRecord 2.3.3

Any help will be greatly appreciated!

You can't reliably call make on a habtm relationship.

Try something like this:

def make_hostname_with_ips
Hostname.make do |hostname|

3.times { hostname.ips << IPAddress.make }
end
end
