Ruby on Rails fixtures not loading relations

I have two models, Event and Registration:

class Event < ApplicationRecord
  has_many :registrations
end

class Registration < ApplicationRecord
  belongs_to :event
end

I also have fixtures for these models:

event_one:
  [...]

registration_one:
  event: event_one

However, in test, if I get the event and check its registrations, there are none.

event = events(:event_one)
puts event.registrations.count # Prints: 0

How do I make sure these associations are loaded for tests?

I did a simple example of your code and try solve the problem, the first thinks I found when review the Event and Registration entries is that the Registrations created has event_ids that dont exist in your database.

A solution:

events.yml

event_one:
  id: 111
  name: MyString
  description: MyString

registrations.yml

registration_one:
  name: MyString
  event_id: 111

registration_two:
  name: MyString
  event_id: 111

event_test.rb

require 'test_helper'

class EventTest < ActiveSupport::TestCase
  def setup
    @event = events(:event_one)
  end

  test "the truth" do
    byebug
  end
end

debugger:

(byebug) @event.registrations
#<ActiveRecord::Associations::CollectionProxy [#<Registration id: 357093202, name: "MyString", event_id: 111, created_at: "2021-01-09 17:21:48", updated_at: "2021-01-09 17:21:48">, #<Registration id: 1055835082, name: "MyString", event_id: 111, created_at: "2021-01-09 17:21:48", updated_at: "2021-01-09 17:21:48">]>

I don't think this is the better solution but work.
