Testing child model with RSPEC and getting the error undefined method id

I have two model classes in a "parent-chid" relationship, or association.

organizations is the parent table / model having the attributes: id, organization_name, created_at and updated_at.

events is the child table / model having the attributes: id, event_description, host_name, created_at, updated_at and organization_id.

The association between organizations and events records is events.organization_id = organizations.id, or as is specified in the model classes:

class Event < ApplicationRecord
...
  belongs_to :organization
...
end

class Organization < ApplicationRecord
...
  has_many  :events, :dependent => :destroy
...
end

The tests for organizations model and organizations controller runs without any errors. The test for events controller is not build yet. The app fully functional and is working without any errors.

The problem I have is that I cannot make the Events model test to pass.

Here is my code.

factories/organizations

FactoryGirl.define do
  factory :organization do
    organization_name { Faker::Company.name }
  end
  factory :invalid_organization, class: Organization do
    organization_name ''
  end
end

factories/events

FactoryGirl.define do
  factory :event do
    event_description { Faker::Lorem.sentence(3) }
    host_name { Faker::Internet.domain_name }
    organization = build(:organization)
    organization_id = organization.id
  end
end

I am trying to create an organization first and use the id for the organization_id attribute of the new event to be created.

And this is the file event_spec.rb

require 'rails_helper'

RSpec.describe Event, type: :model do
  it "has a valid factory" do
    event = build(:event)
    expect(event).to be_valid
  end
  it { is_expected.to validate_presence_of(:event_description) }
  it { is_expected.to validate_presence_of(:host_name) }
  it { is_expected.to validate_presence_of(:organization_id) }
  it { is_expected.to belong_to(:organization) }
end

Basically I want to create first an organization and use this id to be assigned to organization_id when I am creating and event.

When running the test rspec spec/models/event_spec.rb I am getting this error: 

/Users/levi/ror/events-handler/spec/factories/events.rb:6:in `block (2 levels) in <top (required)>': undefined method `id' for #<FactoryGirl::Declaration::Static:0x007febc03db798> (NoMethodError)

Don't know how to fix it or how to write a better test?

I think your event factory should look a bit different:

FactoryGirl.define do
  factory :event do
    event_description { Faker::Lorem.sentence(3) }
    host_name { Faker::Internet.domain_name }
    organization { build(:organization) } 
  end
end
