How do I access my prima studio for my app after it's deployed on fly.io?

I've deployed my app to fly.io, now how do I access prisma studio for my deployed application?

Hi @JLegendz. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

----------------------
To access Prisma Studio for your app deployed on Fly.io, you'll need to follow a few steps to connect to your production database. Here's how you can do it:

Open a tunnel to your Fly.io database using the following command:```fly proxy 5432 -a <db-name>```Replace `<db-name>` with your database app name on Fly.io.
Leave this terminal tab running and open a new terminal tab for the next steps.
Set the `DATABASE_URL` environment variable in your local `.env.server` file to connect to the production database. The format should be:```DATABASE_URL=postgres://<user>:<pw>@localhost:5432/<db_name>?sslmode=disable```
Now you can run Prisma Studio using the Wasp CLI command:```wasp db studio```

This should open up Prisma Studio connected to your production database.

Important notes:

Be careful when interacting with your production database, as any changes you make will affect your live app.
After you're done, make sure to remove the
```
DATABASE_URL
```
```
DATABASE_URL
```
from your local .env.server.env.server file and close the tunnel to avoid accidentally connecting to the production database in the future.

For more detailed information on this process, you can refer to this GitHub issue.

Remember to exercise caution when working with your production database to prevent unintended changes to your live application data.

Sorry @JLegendz, 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:

Perhaps try again in 15mins?

I see bind: address already in use. Can I use something other than 5432?

Let me check the knowledge base for you again. One moment! :books:

----------------------
Yes, you can use a different port if 5432 is already in use. However, the current implementation of Wasp doesn't directly support changing the port for the managed development database. Let me explain the situation and potential workarounds:

Current limitation:Wasp currently uses port 5432 by default for the managed development database, and there's no built-in way to change this port easily. This is a known issue, as described in [this GitHub issue](<https://github.com/wasp-lang/wasp/issues/1049>).
Potential workaround:While Wasp doesn't officially support changing the port, you could try manually modifying the Docker command that Wasp uses to start the database. However, this is not an officially supported method and might cause issues.
Future improvements:The Wasp team is aware of this limitation and is considering implementing solutions such as:
- Allowing users to specify a custom port through environment variables or a settings file.
- Automatically trying different ports until a free one is found.
Alternative approach:If you're running a local PostgreSQL instance that's occupying port 5432, you could consider stopping it temporarily while working on your Wasp project. This would free up the default port for Wasp to use.
For production deployments:If you're seeing this issue with a production deployment on Fly.io, the `fly proxy` command allows you to specify a different local port. For example:```fly proxy 5433:5432 -a <db-name>```This would map the remote 5432 port to your local 5433 port.

It's worth noting that the Wasp team is actively working on improving these aspects of the framework. For now, you might need to use one of the workarounds mentioned above or wait for an official solution to be implemented.

If you need more specific guidance or if this issue is blocking your development, I recommend reaching out to the Wasp community on their Discord channel for more immediate assistance and potential workarounds.

@kapa.ai DATABASE_URL=postgres://<user>:<pw>@localhost:5432/<db_name>?sslmode=disable what user and pw do I provide here? Is it related to docker or fly.io deployment?

kapa.ai•2/28/25, 5:22 AM

Let me check the knowledge base for you again. One moment! :books:

kapa.ai•2/28/25, 5:23 AM

----------------------
The

DATABASE_URL

DATABASE_URL

you're referring to is related to your Fly.io deployment, not Docker. When you're trying to connect to your production database on Fly.io, you need to use the credentials provided by Fly.io. Here's how you can obtain the necessary information:

Database name (`<db_name>`):You can get this by running:```fly postgres connect -a <your-db-app-name>```Then type `\l` to list the databases. Your database name should follow the convention `your_app_name_with_underscores`.
Password (`<pw>`):To get the database password, run:```fly ssh console -a <your-db-app-name>```Then execute:```echo $OPERATOR_PASSWORD```This will display the password for your database.
User (`<user>`):The default user for Fly.io PostgreSQL databases is typically `postgres`.

So, your

DATABASE_URL

DATABASE_URL

should look like this:

DATABASE_URL=postgres://postgres:<password_from_step_2>@localhost:5432/<db_name_from_step_1>?sslmode=disable

DATABASE_URL=postgres://postgres:<password_from_step_2>@localhost:5432/<db_name_from_step_1>?sslmode=disable

Remember to replace <password_from_step_2><password_from_step_2> and <db_name_from_step_1><db_name_from_step_1> with the actual values you obtained from the steps above.

It's important to note that you should only use this connection string temporarily for tasks like seeding the production database. After you're done, make sure to remove this

DATABASE_URL

DATABASE_URL

from your local .env.server.env.server file to avoid accidentally connecting to the production database in the future.

For more detailed information on this process, you can refer to this GitHub issue.

@kapa.ai I did all of that, but now when I try to run wasp start db, it says:

--- [Error] You are using custom database already: -----------------------------

Wasp has detected that you have defined DATABASE_URL env var in your .env.server file.
To have Wasp run the dev database for you, make sure you remove that env var first.

And when I try to run prisma studio it says:

npx prisma studio
Error: Could not find a schema.prisma file that is required for this command.
You can either provide it with --schema, set it as prisma.schemaprisma.schema in your package.json or put it into the default location ./prisma/schema.prisma https://pris.ly/d/prisma-schema-location

And when I try to run wasp start it says:

--- [Error] Can not connect to database: ---------------------------------------

The database needs to be running in order to execute this command. You can easily start a managed dev database with wasp start dbwasp start db.

kapa.ai•2/28/25, 5:49 AM

----------------------
It seems like you're encountering a series of issues related to your database configuration. Let's address them one by one:

The error with `wasp start db`:This error occurs because you have a `DATABASE_URL` defined in your `.env.server` file. Wasp detects this and assumes you want to use a custom database instead of the managed dev database. To resolve this:
- Remove the
```
DATABASE_URL
```
```
DATABASE_URL
```
  from your .env.server.env.server file if you want to use Wasp's managed dev database.
- If you want to keep using your custom database (the one you set up for Fly.io), you should not use wasp start dbwasp start db.
The error with Prisma Studio:Prisma can't find the schema file. When using Wasp, the schema is located in a different place than the default Prisma location. Try running:

   npx prisma studio --schema=./.wasp/out/db/schema.prisma

   npx prisma studio --schema=./.wasp/out/db/schema.prisma

The error with wasp startwasp start:
This error suggests that Wasp can't connect to the database. This could be because:
- If you removed the
```
DATABASE_URL
```
```
DATABASE_URL
```
  , Wasp is trying to use its managed database, but it's not running.
- If you kept the
```
DATABASE_URL
```
```
DATABASE_URL
```
  , it might be pointing to a database that's not accessible (like the Fly.io database without an active tunnel).

To resolve these issues:

Decide whether you want to use Wasp's managed dev database or connect to your Fly.io database:
- For local development with Wasp's managed database:
  - Remove
    DATABASE_URL
    DATABASE_URL
    from .env.server.env.server
  - Run wasp start dbwasp start db in one terminal
  - Run wasp startwasp start in another terminal
- To connect to your Fly.io database:
  - Keep
    DATABASE_URL
    DATABASE_URL
    in .env.server.env.server
  - Open a tunnel with fly proxy 5432 -a <your-db-app-name>fly proxy 5432 -a <your-db-app-name>
  - Run wasp startwasp start (don't use wasp start dbwasp start db)

kapa.ai•2/28/25, 5:49 AM

For Prisma Studio, always use:
```
wasp db studio
```
```
wasp db studio
```
This ensures that Wasp sets up the correct environment for Prisma.

Remember, connecting to your production Fly.io database should only be done temporarily for specific tasks. For regular development, it's recommended to use Wasp's managed dev database or a local PostgreSQL instance.

If you're still encountering issues, you might want to check the Wasp documentation on connecting to databases for more detailed information.
