Hi @Bruno Njeru. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
I'm sorry, but the knowledge sources do not provide explicit instructions or confirmation on how to perform a database reset (i.e., dropping all data and tables and reapplying migrations) directly on a deployed Fly.io app using Wasp. The available documentation and discussions cover running migrations, seeding, and connecting to the production database via a proxy, but do not mention a supported or recommended way to run wasp db reset or an equivalent operation in a production environment on Fly.io.
If you need to reset your production database, you may need to handle this manually (e.g., by connecting to the database and running SQL commands yourself), but please proceed with caution, as this can result in data loss. Always ensure you have backups and understand the implications before resetting a production database.
If you need more detailed guidance, you may want to ask in the Wasp community or check for updates in the official documentation, as this is a sensitive operation and may require steps not currently documented in the sources provided.

Sorry @Bruno Njeru, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist:

is there a way you can view the db of the deployed app on fly? similar to wasp db studio in dev @kapa.ai
Let me check the knowledge base for you again. One moment! :books:

Yes, you can view the database of your deployed app on Fly.io in a way similar to using wasp db studio in development. The recommended approach is to open a tunnel to your production database using the Fly CLI, set your local DATABASE_URL to point to the tunneled database, and then run wasp db studio locally. Here’s how you can do it:
1. Open a tunnel to your Fly.io Postgres database:
Leave this terminal running.
2. In another terminal, set your DATABASE_URL in your local .env.server file to point to the tunneled database. For example:
(You can get the database name and password using Fly CLI commands as described in the docs.)
3. Now, run:
This will open Prisma Studio connected to your production database through the tunnel.
Remember to remove the production DATABASE_URL from your .env.server after you’re done to avoid accidental changes to your production data in the futureUpdate the database docs on seeding the production DB on Fly, How to interact with database in prisma studio after deployment?.
This approach allows you to inspect and interact with your production database in a safe and familiar way, similar to your development workflow.

The error message:
means that Wasp is unable to connect to a running database instance. This typically happens if:
- The database server (e.g., PostgreSQL) is not running.
- The connection details (host, port, credentials) are incorrect.
- Docker is not running (if you rely on Wasp to start the dev database for you).
How to resolve:
1. If you want Wasp to manage the dev database:
- Make sure Docker is installed and running. - Ensure that the

- Make sure your database server is running and accessible at the address specified in your
- Make sure Docker is installed and running. - Ensure that the
DATABASE_URL environment variable is not set in your .env.server file. If it is, remove or comment it out.
- Run wasp start db to start the managed dev database.Docs: Connecting to a Database 2. If you are using your own database:
- Make sure your database server is running and accessible at the address specified in your
DATABASE_URL.
- Double-check the credentials and connection string in .env.server.
If you still encounter issues, check that port 5432 is available and not blocked by another process, and that Docker is correctly installed and in your system's PATH if you are using the managed dev database option.
If you see the error about "You are using custom database already," it means Wasp detected a DATABASE_URL and will not start its own dev database until you remove that variable from .env.serverDocs: Connecting to a Database.
If you need more specific troubleshooting, please provide details about your setup and any additional error messages.
