Factory Bot Failures in Rails App - ruby-on-rails

Question

So I have the following models: Regions and Locations. They look fine and I can load up the page just fine. The issue gets with factory bot.
class Region < ApplicationRecord
scope :ordered, -> { order(name: :desc) }
scope :search, ->(term) { where('name LIKE ?', "%#{term}%") }
has_many :locations, dependent: :destroy
end
class Location < ApplicationRecord
scope :ordered, -> { order(name: :desc) }
scope :search, ->(term) { where('name LIKE ?', "%#{term}%") }
belongs_to :region
end
For my factories I have the following:
FactoryBot.define do
factory :region do
name 'MyString'
end
end
FactoryBot.define do
factory :location do
name 'MyString'
hours_operation 'MyString'
abbreviation 'MyString'
region nil
end
end
Both of those were rendered easily enough and the only change I made to them was switching out double quotations with single quotations. But when I run a bin/test I keep getting the following errors: Admin::LocationsController show should render the show page Failure/Error: location = FactoryBot.create(:location) ActiveRecord::RecordInvalid:Validation failed: Region must exist
Then a coordinating example of the failure: rspec ./spec/controllers/admin/locations_controller_spec.rb:16 # Admin::LocationsController show should render the show page
So I check out spec/controllers/admin/locations_controller_spec.rb and here's the code:
require 'rails_helper'
RSpec.describe Admin::LocationsController, type: :controller do
before(:each) do
activate_session(admin: true)
end
describe 'index' do
it 'should render the index' do
get :index
expect(response).to have_http_status :success
end
end
describe 'show' do
it 'should render the show page' do
location = FactoryBot.create(:location)
get :show, params: { id: location.id }
expect(response).to have_http_status :success
end
it 'should return a 404 error' do
get :show, params: { id: 1 }
expect(response).to have_http_status :not_found
end
end
describe 'new' do
it 'should render the new page' do
get :new
expect(response).to have_http_status :success
end
end
describe 'edit' do
it 'should render the edit page' do
location = FactoryBot.create(:location)
get :edit, params: { id: location.id }
expect(response).to have_http_status :success
end
end
describe 'create' do
it 'should create the record' do
expect do
post :create, params: { location:
FactoryBot.attributes_for(:location) }
end.to change(Location, :count).by(1)
end
end
describe 'update' do
it 'should update the record' do
location = FactoryBot.create(:location)
current_value = location.name
new_value = current_value + '-Updated'
expect do
patch :update, params: { id: location.id, location: { name: new_value } }
location.reload
end.to change(location, :name).to(new_value)
end
end
describe 'destroy' do
it 'should destroy the record' do
location = FactoryBot.create(:location)
expect do
delete :destroy, params: { id: location.id }
end.to change(Location, :count).by(-1)
end
end
end
The line it's references is: it 'should render the show page'.
Honestly I don't know what's causing it to fail. I thought it might be an association issues but when I went to try and do something like associations :location it caused even more errors to populate. Am I just missing something in the spec controllers for association?
EDIT/UPDATE: Fixed five of the six errors using association :region in location. But I'm getting: Failure/Error: expect do post :create, params: { location: FactoryBot.attributes_for(:location) } end.to change(Location, :count).by(1) expected #count to have changed by 1, but was changed by 0.

You can create associations in factory-bot using after_create, try this
FactoryBot.define do
factory :location do
name 'MyString'
hours_operation 'MyString'
abbreviation 'MyString'
after(:create) do |location, evaluator|
location.region = FactoryBot.create(:region)
end
end
end
All this is doing is creating a region object and associating it to the location object.
