-- Fix round deletion FK constraint errors
-- Add CASCADE on Evaluation.formId so deleting EvaluationForm cascades to Evaluations
-- Add SET NULL on ProjectFile.roundId so deleting Round nullifies the reference

-- AlterTable: Evaluation.formId -> onDelete CASCADE
ALTER TABLE "Evaluation" DROP CONSTRAINT "Evaluation_formId_fkey";
ALTER TABLE "Evaluation" ADD CONSTRAINT "Evaluation_formId_fkey"
    FOREIGN KEY ("formId") REFERENCES "EvaluationForm"("id") ON DELETE CASCADE ON UPDATE CASCADE;

-- AlterTable: ProjectFile.roundId -> onDelete SET NULL
ALTER TABLE "ProjectFile" DROP CONSTRAINT "ProjectFile_roundId_fkey";
ALTER TABLE "ProjectFile" ADD CONSTRAINT "ProjectFile_roundId_fkey"
    FOREIGN KEY ("roundId") REFERENCES "Round"("id") ON DELETE SET NULL ON UPDATE CASCADE;
