Hi @ArDev. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
The
wasp db migrate-dev command in Wasp is used to synchronize your development database with the current state of your schema, which is defined by your entities. If there are any changes in the schema, it generates a new migration and applies any pending migrations to the database. This command primarily executes Prisma commands behind the scenes [^1^].
It does not migrate your local database to your DATABASE_URL. Instead, it ensures that your development database corresponds to the current state of your schema. If you have made changes to your entities, you would need to run wasp db migrate-dev to create a new migration reflecting these changes and apply it to your database [^5^].
If you want to connect to an existing database, you can set the DATABASE_URL environment variable in your .env.server file or inline when running the wasp command [^10^].

@kapa.ai but i get this - [+] Added unique index on columns (email)
[+] Added unique index on columns (username)
- The migrations recorded in the database diverge from the local migrations directory.
✔ We need to reset the "public" schema at "aws-0-us-east-1.pooler.supabase.com:5432"
Do you want to continue? All data will be lost. … no

The message you're seeing is a prompt from Prisma, the database toolkit that Wasp uses under the hood. It's indicating that the migrations recorded in your database are different from the migrations in your local directory. This can happen if you've made changes to your entities or schema that haven't been applied to your database yet.
The ✔ We need to reset the "public" schema at "aws-0-us-east-1.pooler.supabase.com:5432" message is telling you that in order to synchronize your database with your local schema, it needs to reset your database. This means all data in your database will be lost.
If you choose to continue, it will reset your database and apply the new migrations, making your database schema match your local schema. If you don't want to lose the data in your database, you should not proceed.
Remember to always backup your data before performing operations that could potentially delete it. If you're working in a development environment and it's okay to lose the data, you can proceed.
If you're unsure or if this is a production database, it would be best to seek advice from a database administrator or someone with more experience managing databases.
