litellm - 💡(How to fix) Fix LiteLLM upgrading guide [1 comments, 2 participants]

I always facing issue when did the LiteLLM upgrade, especially on prisma side, always column missing and migration error. even i download the latest prisma schema also having issue to apply it into my current DB.

Fix Plan

The fix involves a careful Prisma migration process to avoid column missing and migration errors during the LiteLLM upgrade.

Step-by-Step Solution

To upgrade from one version to another with new columns or tables:

• Backup your database before making any changes.
• Update your Prisma schema to match the new version.
• Run npx prisma migrate dev to apply the changes to your local database.
• Run npx prisma migrate deploy to apply the changes to your production database.
• Verify the migration by checking your database schema.

Example Prisma schema update:

// Add new column to existing table
model User {
  id       String   @id @default(cuid())
  name     String
  email    String   @unique
  // New column
  phoneNumber String?
}

// Add new table
model Order {
  id        String   @id @default(cuid())
  userId    String
  user      User     @relation(fields: [userId], references: [id])
  orderDate DateTime @default(now())
}

Example migration command:

npx prisma migrate dev --name add-phone-number-and-order-table

Verification

Check your database schema to ensure the new columns and tables have been added successfully. You can use a database client or run npx prisma studio to visualize your database schema.

Extra Tips

• Always backup your database before making changes.
• Use npx prisma migrate dev to test migrations locally before deploying to production.
• Use npx prisma migrate deploy to apply migrations to your production database.
