How to Run

Initialize DB

1. Create a database

postgres=# CREATE DATABASE ibanim;

2. Create a user as owner of database

postgres=# CREATE USER ibanim WITH ENCRYPTED PASSWORD 'ibanim';

postgres=# ALTER DATABASE ibanim OWNER TO ibanim;

3. Grant all privileges to user for the database

postgres=# GRANT ALL PRIVILEGES ON DATABASE ibanim TO ibanim;

4. Configure the db in db.go

// ConnectDB : connecting DB
func ConnectDB() (*DB, error) {
	db, err := gorm.Open("postgres", "host=localhost port=5432 user=ibanim dbname=ibanim password=ibanim sslmode=disable")

	if err != nil {
		panic(err)
	}

	return &DB{db}, nil
}

or with Docker

host address should be edited to host.docker.internal to connect a host interface.

// ConnectDB : connecting DB
func ConnectDB() (*DB, error) {
	db, err := gorm.Open("postgres", "host=host.docker.internal port=5432 user=ibanim dbname=ibanim password=ibanim sslmode=disable")

	if err != nil {
		panic(err)
	}

	return &DB{db}, nil
}
