Foreign Key Relationships

VendorAccountDetails → VendorProfile

ALTER TABLE "VendorAccountDetails" 
ADD CONSTRAINT "VendorAccountDetails_vendorAddress_fkey" 
FOREIGN KEY ("vendorAddress") REFERENCES "VendorProfile"("address") 
ON DELETE CASCADE ON UPDATE CASCADE;

VendorTrackingSettings → VendorProfile

ALTER TABLE "VendorTrackingSettings" 
ADD CONSTRAINT "VendorTrackingSettings_vendorAddress_fkey" 
FOREIGN KEY ("vendorAddress") REFERENCES "VendorProfile"("address") 
ON DELETE CASCADE ON UPDATE CASCADE;

Escrow → VendorProfile

ALTER TABLE "Escrow" 
ADD CONSTRAINT "Escrow_vendorAddress_fkey" 
FOREIGN KEY ("vendorAddress") REFERENCES "VendorProfile"("address") 
ON DELETE RESTRICT ON UPDATE CASCADE;

Migration Steps

1. Generate Prisma Client

npm run db:generate

2. Apply Migration

npm run db:migrate

Or apply the manual migration:

psql $DATABASE_URL -f prisma/migrations/20260527120000_add_vendor_account_details_and_tracking/migration.sql

3. Seed Database

npm run db:seed

Deployment to Staging

Docker Compose Deployment

The migration will run automatically when deploying to staging containers via Docker Compose, as the database initialization scripts are included in the container setup.

Manual Staging Deployment

# Set staging environment
export NODE_ENV=staging
export DATABASE_URL=postgresql://user:password@staging-db-host:5432/trustlink_staging

# Generate Prisma client
npm run db:generate

# Apply migration
npm run db:migrate

# Seed with test data
npm run db:seed

Verification

After deployment, verify the tables were created successfully:

npm run db:studio

Or run a quick check:

npx prisma db pull
npx prisma format

Acceptance Criteria

✅ Relational foreign key bindings match target identity tables perfectly

• VendorAccountDetails.vendorAddress → VendorProfile.address (CASCADE delete)
• VendorTrackingSettings.vendorAddress → VendorProfile.address (CASCADE delete)
• Escrow.vendorAddress → VendorProfile.address (RESTRICT delete)
• All foreign keys use the correct reference fields and cascade rules

✅ Database structures deploy smoothly across staging test containers

• Migration SQL is compatible with PostgreSQL
• Foreign key constraints are properly defined
• Indexes are created for query performance
• Default values are set appropriately
• Seed data includes all new tables
• Docker deployment scripts will execute migration automatically

Schema Changes Summary

Modified Tables

• VendorProfile: Added relations to VendorAccountDetails and VendorTrackingSettings
• Escrow: Added relation to VendorProfile

New Tables

• VendorAccountDetails: 25 fields for comprehensive vendor account information
• VendorTrackingSettings: 20 fields for tracking configuration

New Relations

• VendorProfile.accountDetails → VendorAccountDetails (1:1)
• VendorProfile.trackingSettings → VendorTrackingSettings (1:1)
• VendorProfile.escrows → Escrow (1:N)

Rollback Procedure

If needed, rollback the migration:

npx prisma migrate resolve --rolled-back 20260527120000_add_vendor_account_details_and_tracking

Or manually:

DROP TABLE IF EXISTS "VendorTrackingSettings";
DROP TABLE IF EXISTS "VendorAccountDetails";
ALTER TABLE "Escrow" DROP CONSTRAINT IF EXISTS "Escrow_vendorAddress_fkey";

Testing

Unit Testing

// Test foreign key constraints
await prisma.vendorAccountDetails.create({
  data: {
    vendorAddress: 'nonexistent_address',
    // ... other fields
  }
});
// Expected: Foreign key constraint violation error

Integration Testing

// Test cascade delete
const vendor = await prisma.vendorProfile.create({
  data: {
    address: 'test_address',
    businessName: 'Test Vendor',
    accountDetails: {
      create: { /* account details */ }
    },
    trackingSettings: {
      create: { /* tracking settings */ }
    }
  }
});

await prisma.vendorProfile.delete({
  where: { address: 'test_address' }
});

// Verify: accountDetails and trackingSettings are also deleted

Notes

• The migration uses CASCADE delete for vendor-related tables to maintain data integrity
• Escrow uses RESTRICT delete to prevent accidental deletion of vendors with active transactions
• All timestamps use UTC timezone for consistency
• Custom fields use JSONB for flexibility
• Indexes are created on frequently queried fields for performance
