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: 1. The error suggests that new migrations cannot be applied due to existing failed migrations in the database. 2. 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." 3. 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 .... 4. 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. 5. 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. 6. 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. Remember, when dealing with database migrations in production, always proceed with caution and ensure you have proper backups before making any changes. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- 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?

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: 1. First, ensure you have the latest changes in your local development environment. Run wasp db migrate-dev locally to create the necessary migration files. 2. Deploy your updated code to Fly.io using the command 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). 3. 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). 4. Now, you need to temporarily set your production database URL in your local .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). 5. 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. 6. After applying the migrations, remove the production database URL from your local .env.server file to avoid accidental interactions with the production database in the future. 7. 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. 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. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @NEROX, I seem to be having a bit of trouble.

✅ Solved 1. Opened a tunnel: fly proxy 5432 -a myapp-db 2. Did a wasp db migrate-dev 3. Did a wasp deploy fly deploy ⚠️ EDIT: DATA MAY BE LOST USING THIS METHOD yeah I fixed migrating my db first with the tunnel proxy in prod.

You don't use the GitHub action?
NEROX
NEROXOP4w ago
What github action? To deploy? Or do you mean something else?
VS
VS4w ago
When you push to prod it would auto update your website and run that command (database merge) via GitHub actions 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
NEROX
NEROXOP4w ago
Yep, I'm actually at development stage, so nuking my prod db it's fine at this point:smugboi:
VS
VS4w ago
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?

Question, how do you handle the providerEmail from Dummy to, for example Sendrgrid? Or you just change every time?
VS
VS3w ago
I don't understand your question for dev it is dummy for prod it is SendGrid

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.
NEROX
NEROXOP3w ago
Uhh, I had no data:smugboi: The main stats I use Analytics with Tag Manager Yeah, you may lose data by this method
Sven
Sven3w ago
What other method i dont? Just deploy?
NEROX
NEROXOP3w ago
I found that I can fix in dev by modifiying the migration.sql ,but in production still nothing acomplished... So I think that a similar method should be to prod
Sven
Sven3w ago
But like a normal migration in dev how would I apply this to prod without loosinf data?
NEROX
NEROXOP3w ago
That's the problem, I'm still messing with it.
Sven
Sven3w ago
Hmm so wasp deploy fly deploy Does not work
NEROX
NEROXOP3w ago
why not but, how did you update that db without losing the dev db data?
Sven
Sven3w ago
What do you mean? I mean for migrating production
NEROX
NEROXOP3w ago
migrating in development
Sven
Sven3w ago
Just wasp db migrste dev That migrates my db to add for example a new model And keeps the seeded data in development
NEROX
NEROXOP3w ago
But did you have data? wow
Sven
Sven3w ago
Yes i had Why?
NEROX
NEROXOP3w ago
Because I lost some data in dev this morning migrating
Sven
Sven3w ago
Oh shitt Thats not good I made aa dev change and want to apply it to production but scared to loose ddata
