When using FactoryGirl (now known as FactoryBot) to create records with associations and validations, it's essential to ensure that the associations are correctly set up to avoid validation failures. The issue you described, where
validates_presence_of fails even though the foreign key is associated, could be due to incorrect setup of the association or a missing step in your FactoryGirl factory.
Here are some steps you can follow to resolve the issue:
Check the Association: Ensure that the association between the two models is correctly defined in your ActiveRecord model classes. Make sure the
belongs_toassociation is set up properly.
For example, if you have a
Company, your model definitions should look like this:ruby
# app/models/user.rb class User < ApplicationRecord belongs_to :company validates_presence_of :company # Ensure that the association is present end # app/models/company.rb class Company < ApplicationRecord has_many :users end
Use FactoryBot Associations: In your FactoryBot factory for the
Usermodel, make sure you're correctly associating it with a
Company. Use the
associationmethod to establish the association.ruby
# spec/factories/users.rb FactoryBot.define do factory :user do # Other attributes for the user # Associate the user with a company association :company, factory: :company end end
Ensure Factories Are Loaded: Confirm that the FactoryBot factories are loaded and available in your test environment. In your
rails_helper.rb, make sure you have included the necessary configuration to load the factories.ruby
# spec/spec_helper.rb or spec/rails_helper.rb require 'factory_bot_rails' FactoryBot.find_definitions
Create the Associated Object: Make sure you're creating the associated object (
Company) before creating the
Userobject. Otherwise, the
validates_presence_ofvalidation may fail because the associated object doesn't exist.
For example, in your test code, create the
Companyfirst and then the associated
company = create(:company) user = create(:user, company: company)
By following these steps, you should be able to create
User objects with associated
Company objects successfully, and the
validates_presence_of validation should pass. If you're still facing issues, double-check your model associations and the configuration of your FactoryBot factories to ensure everything is set up correctly.
