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

----------------------
This error message indicates that there are failed migrations in your target database when using Prisma with Wasp. This situation can occur in production environments and requires careful handling. Here's what you need to know:

The error suggests that new migrations cannot be applied due to existing failed migrations in the database.
To resolve this issue, you'll need to use the `prisma migrate resolve` command. This is mentioned in the **Github issue about Prisma CLI access** (<https://github.com/wasp-lang/wasp/issues/216>), which states:"We should also enable usage of prisma for production -> for example, if migration needs to be resolved on production database `prisma migrate resolve`."
However, it's important to note that Wasp currently doesn't have a direct command for this. The same issue suggests that Wasp should provide a way to access Prisma commands directly, possibly through a command like
```
wasp prisma ...
```
```
wasp prisma ...
```
.
When dealing with production databases, it's crucial to be cautious. As mentioned in another Github issue about migration deployment (https://github.com/wasp-lang/wasp/issues/215), it's not recommended to run migration commands locally on a production database.
For now, you might need to access your production database directly to resolve the failed migrations. The exact steps would depend on your hosting environment and database setup.
In the future, Wasp may provide more streamlined ways to handle these situations, as the team is aware of the need for better migration workflows, especially for production environments.

kapa.ai•11/13/24, 9:22 AM

Remember, when dealing with database migrations in production, always proceed with caution and ensure you have proper backups before making any changes.

Sorry @NEROX, 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?

NEROXOP•11/13/24, 9:24 AM

@kapa.ai I had changed things in my db. how can I solve that now In prod? (deployed in fly)

kapa.ai•11/13/24, 9:24 AM

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

----------------------
To resolve database changes in your production environment deployed on Fly.io, you'll need to carefully apply migrations. Here's how you can approach this:

First, ensure you have the latest changes in your local development environment. Run
```
wasp db migrate-dev
```
```
wasp db migrate-dev
```
locally to create the necessary migration files.
Deploy your updated code to Fly.io using the command
```
wasp deploy fly deploy
```
```
wasp deploy fly deploy
```
. This will update your application code on Fly.io Wasp Docs - Fly.io Deployment (https://wasp-lang.dev/docs/advanced/deployment/cli#flyio).
To interact with your production database on Fly.io, you'll need to open a tunnel. Use the following command:

   fly proxy 5432 -a <your-db-name>

   fly proxy 5432 -a <your-db-name>

Leave this terminal tab running and open a new one for further commands Github Issue - DB Seeding (https://github.com/wasp-lang/wasp/issues/1464).

Now, you need to temporarily set your production database URL in your local
```
.env.server
```
```
.env.server
```
file. Be very careful with this step, as noted in the Wasp Docs - Connecting to Existing Database (https://wasp-lang.dev/docs/data-model/backends#connecting-to-an-existing-database).
With the tunnel open and the production database URL set, you can now run:

   wasp db migrate-deploy

   wasp db migrate-deploy

This command will apply your migrations to the production database.

After applying the migrations, remove the production database URL from your local
```
.env.server
```
```
.env.server
```
file to avoid accidental interactions with the production database in the future.
Close the tunnel you opened in step 3.

Remember, working with production databases requires caution. Always ensure you have recent backups before performing any operations that modify the database structure.

kapa.ai•11/13/24, 9:25 AM

Also, note that Wasp is working on improving this process. As mentioned in a Github Issue about migration deployment (https://github.com/wasp-lang/wasp/issues/215), there are plans to make this process more streamlined and secure in future versions of Wasp.

NEROXOP•11/13/24, 9:44 AM

Solved

Opened a tunnel:

fly proxy 5432 -a myapp-db

fly proxy 5432 -a myapp-db

Did a
```
wasp db migrate-dev
```
```
wasp db migrate-dev
```

Did a

wasp deploy fly deploy

wasp deploy fly deploy

EDIT: DATA MAY BE LOST USING THIS METHOD

NEROXOP•11/13/24, 9:45 AM

yeah I fixed migrating my db first with the tunnel proxy in prod.

sachdva•11/13/24, 9:53 AM

You don't use the GitHub action?

Ssachdva You don't use the GitHub action?

NEROXOP•11/13/24, 10:14 AM

What github action? To deploy? Or do you mean something else?

sachdva•11/13/24, 10:20 AM

When you push to prod it would auto update your website and run that command (database merge) via GitHub actions

sachdva•11/13/24, 12:26 PM

You will need these commands when you make breaking changes
fly ssh console -a yourappname-server
find where schema.prisma is (cd .. to db)
npx prisma migrate reset --force
npx prisma migrate dev --name init
npx prisma migrate deploy

This resets your database and forces a new migration. Don't do this when you have data you need to save, this removes all users too.
I'm still in development and make breaking changes quite often where I have to nuke my local database, this is to nuke your prod database too

NEROXOP•11/13/24, 12:40 PM

Yep, I'm actually at development stage, so nuking my prod db it's fine at this point:smugboi:

sachdva•11/13/24, 1:07 PM

Sure, i would recommend to use the GitHub action for prod and then when you have to nuke then use the commands I sent - did you get further with the google Analytics api?

NEROXOP•11/13/24, 3:43 PM

Question, how do you handle the

providerEmail

providerEmail

from

Dummy

Dummy

to, for example

Sendrgrid

Sendrgrid

? Or you just change every time?

sachdva•11/13/24, 4:01 PM

I don't understand your question
for dev it is dummy for prod it is SendGrid

Sven•11/13/24, 9:19 PM

no data lost here? so when i add a model in my dev environment and this is not in production yet (where all valuable data is stored) then i can do:

$ fly proxy 5432 -a myapp-db
$ wasp db migrate-dev
$ wasp deploy fly deploy

Without lossing any data?

I just added a model and a relation to an existing table from that model.

Yeah, you may lose data by this method

NNEROX Yeah, you may lose data by this method

What other method i dont?

Sven•11/13/24, 10:28 PM

Just deploy?

I found that I can fix in dev by modifiying the

That's the problem, I'm still messing with it.

Sven•11/13/24, 10:31 PM

Hmm so wasp deploy fly deploy

Sven•11/13/24, 10:31 PM

Does not work

NEROXOP•11/13/24, 10:31 PM

why not

NEROXOP•11/13/24, 10:32 PM

but, how did you update that db without losing the dev db data?

NNEROX but, how did you update that db without losing the dev db data?

Sven•11/13/24, 10:34 PM

What do you mean?

SSven Hmm so wasp deploy fly deploy

Sven•11/13/24, 10:34 PM

I mean for migrating production

SSven What do you mean?

NEROXOP•11/13/24, 10:35 PM

migrating in development

Sven•11/13/24, 10:35 PM

Just wasp db migrste dev

Sven•11/13/24, 10:35 PM

That migrates my db to add for example a new model

Sven•11/13/24, 10:35 PM

And keeps the seeded data in development

NEROXOP•11/13/24, 10:35 PM

But did you have data?

NEROXOP•11/13/24, 10:36 PM

wow

Sven•11/13/24, 10:36 PM

Yes i had

Sven•11/13/24, 10:36 PM

Why?

NEROXOP•11/13/24, 10:37 PM

Because I lost some data in dev this morning migrating

Sven•11/13/24, 10:37 PM

Oh shitt

Sven•11/13/24, 10:37 PM

Thats not good

Sven•11/13/24, 10:37 PM

I made aa dev change and want to apply it to production but scared to loose ddata
