import (
	"errors"
	"github.com/Fs02/go-paranoid"
	"github.com/jinzhu/gorm"
	_ "github.com/jinzhu/gorm/dialects/mysql"
)

type Transaction struct {
	ID uint
}

func retrieve() (Transaction, error) {
	db, err := gorm.Open("mysql", "root@(127.0.0.1:3306)/db?charset=utf8&parseTime=True&loc=Local")
	// panic if error
	paranoid.Panic(err, "Error opening database connection")

	trx := Transaction{}
	query := db.First(&trx, 1000)

	if query.RecordNotFound() {
		return trx, errors.New("not found")
	}

	// it'll panic on unknown or untestable error
	paranoid.Panic(query.Error, "Failed when fetching transaction %+v", trx)
	return trx, nil
}

func main() {
	retrieve()
}

There's also paranoid.PanicFunc which usefull when you want to run any specific function before panic (ie: rollback).
