   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 👍

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

   I agree
