Problems with fixtures and HABTM

Rails
1

I have:

treatments.yml

treatment3:
id: 3
code: T3
description: “Desarrollo de una política de seguridad”
reduction: 0.3
document: “D01_Politica_Seguridad”
account_id: 1
soa_lines: soa_line3
treatment4:
id: 4
code: T1
description: “Inclusión en el mantenimiento de los sistemas un chequeo
de la seguridad del navegador en uso.”
reduction: 0.1
document: “D10_Mantenimiento_Equipos.docx”
account_id: 2
soa_lines: soa_line4

and:

soa_lines.yml

soa_line3:
account_id: 1
id: 3
justification: “La política de seguridad es fundamental para el
funcionamiento del sistema”
control_id: 3
applicability: true
soa_line4:
account_id: 2
id: 4
justification: “Es necesario proteger las transacciones en línea que
realiza la organización”
control_id: 1
applicability: true
treatments: treatment4

And both models have:

treatment.rb

has_and_belongs_to_many :soa_lines

soa_line.rb

has_and_belongs_to_many :treatments

But when I try to access to treatment.soa_lines it returns nothing:

test “successful treatment modification” do
treatment = treatments(:treatment4)

puts "Id", treatment.id
puts "Code", treatment.code
puts "Description", treatment.description
puts "Reduction", treatment.reduction
puts "Account", treatment.account.name
puts "Soa Lines", treatment.soa_lines

All puts return correct values but treatment.soa_lines is []

What I’m doing wrong? What can I check to correct this?

The problem was that if you want to use the name convention for defining
relationships like in:

treatments: treatment4

The treatment fixture cannot have an id attribute. Ids should be managed
by Rails in this case.
