UUID associations are not set

[antulik]

FixtureBot.define do
 user :alice do
 email "one@mail.com"
 end

 project :blah do
 name "Project 1"
 user :alice
 end
end

outputs projects.yml

blah:
 id: 1afb5dc2-d94e-556a-b311-1d74d0a0e136
 name: Project 1

Expected project.user_id to be set

I was testing the gem and ran into the same issue. The problem seems to be caused by a missing foreign_key constraint.
The code relies on the presence of FK to establish associations.

So there are currently two workarounds:

1. Add the missing FK constraint. Then the association IDs will be correctly assigned in the generated fixtures.

   add_foreign_key :projects, :users

2. Manually assign the ID if adding FK is not an option (using the same method used internally to generate the deterministic IDs)

   FixtureBot.define do
    user :alice do
    email "one@mail.com"
    end
   
    project :blah do
    name "Project 1"
    use_id FixtureBot::Key::Integer.generate(:users, :alice)
    end
   end

However, I still consider this a bug and expect this missing FK to be handled by fixturebot.

I can confirm adding foreign keys fixes it 👍

I agree
