How do I configure GORM for my Go application?

To configure GORM, you need to set up a database connection and define your models. What database are you using?

I'm using PostgreSQL. Can you show me an example?

Sure! First, install the GORM package and the PostgreSQL driver. Then, use the following code to connect:

import (
    "gorm.io/driver/postgres"
    "gorm.io/gorm"
)

func main() {
    dsn := "user=gorm password=gorm dbname=gorm port=9920 sslmode=disable"
    db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{})
    if err != nil {
        panic("failed to connect to the database")
    }
}

This will establish a connection to your PostgreSQL database.

What about defining models?

You can define models by creating structs. For example:

type User struct {
    gorm.Model
    Name  string
    Email string `gorm:"unique"`
}

This struct represents a user with a unique email.

How do I run migrations?

To run migrations, use the AutoMigrate method:

db.AutoMigrate(&User{})

This will create the users table in your database if it doesn't exist.
