Associations interact with each other

[Stefan Wintermeyer]

Hi,

I'm stuck with the following scenario (the database layout is fixed I
can't change it):

sip_domain.rb
has_many :tenants

tenant.rb
belongs_to :sip_domain
has_many :users

user.rb
belongs_to :tenant
has_many :sip_accounts
validate_presence_of :tenant

sip_account.rb
belongs_to :sip_domain
belongs_to :user
belongs_to :tenant
validate_presence_of :sip_domain, :user, :tenant

I'm searching for a way to define a factory for sip_account. I have
factories for all the other models but sip_account is a tough one.

If I do something like:

Factory.define :sip_account do |f|
f.association :sip_accountable, :factory => :user
f.sequence(:auth_name) {|n| "auth_name#{n}" }
f.sequence(:caller_name) {|n| "Foo Account #{n}" }
f.sequence(:password) {|n| "123" }
f.association :tenant
f.association :sip_domain
end

Than the user doesn't belong to the tenant and the tenant doesn't
belong to the sip_domain. And that breaks the validations which is a
bit more complicated that the example above.

How can I let the different associations interact with each other?

I think you can deal with this using an after_build block.

FactoryGirl.define :sip_account do

  f.sequence(:auth_name) {|n| "auth_name#{n}" }
  f.sequence(:caller_name) {|n| "Foo Account #{n}" }
  f.sequence(:password) {|n| "123" }
  f.association :tenant

  f.association :sip_domain

  after_build do |sip_account|

    sip_account.tenant ||= FactoryGirl.build :tenant, sip_domain: sip_domain

    sip_account.sip_accountable ||= FactoryGirl.build :user, tenant: sip_account.tenant

  end

end

Thanks for the advice with after_build. That solved the problem.
