If you’re looking for an efficient and user-friendly ORM framework, Korm is a powerful choice that successfully tackles many of the limitations associated with traditional frameworks like Django. Let’s dive into how to set up and utilize Korm for your projects!

Introduction to Korm

Korm is inspired by the Django framework but is tailored for Go programming, enhancing performance and scalability. It allows seamless integration with websockets using both WithBus for data synchronization across multiple Korm instances and WithDashboard for creating server dashboards.

Installation Guide

To start using Korm, you need to install it along with any database drivers desired. Here’s how to do it:

• Run the following command in your terminal:

go get -u github.com/kamalshkeir/korm@v1.93.5

• Install the database drivers of your choice, for example:

go get -u github.com/kamalshkeir/sqlitedriver@latest

Establishing a Connection to the Database

After installation, you can connect to your database. The syntax differs based on the database being used:

• For SQLite:

  err := korm.New(korm.SQLITE, dbName, sqlitedriver.Use())

• For Postgres:

  err := korm.New(korm.POSTGRES, dbName, pgdriver.Use(), user:password@localhost:5432)

• For MySQL:

  err := korm.New(korm.MYSQL, dbName, mysqldriver.Use(), user:password@localhost:3306)

The Hello World Example

To see Korm in action, let’s create a simple database model:

package main

import (
    "fmt"
    "time"
    "github.com/kamalshkeir/lg"
    "github.com/kamalshkeir/korm"
    "github.com/kamalshkeir/sqlitedriver"
)

type Class struct {
    Id       uint   `korm:pk`
    Name     string
    Students []Student
}

type Student struct {
    Id      uint   `korm:pk`
    Name    string
    Class   uint   `korm:fk:classes.id:cascade:cascade`
    Classes Class
}

func main() {
    err := korm.New(korm.SQLITE, db, sqlitedriver.Use())
    if lg.CheckError(err) return
    defer korm.Shutdown()

    server := korm.WithDashboard(:9313)
    korm.WithShell()
    err = korm.AutoMigrate[Class](classes)
    lg.CheckError(err)
    err = korm.AutoMigrate[Student](students)
    lg.CheckError(err)

    server.Run()
}

In this example:

• Class and Student define the data structures.
• We establish a connection to an SQLite database.
• The AutoMigrate function ensures that the database schema matches the structure of our Go structs.

Korm’s Unique Features

• High concurrency handling with built-in caching mechanisms.
• Dashboard integration for real-time log monitoring.
• Supports both nested and embedded structs, enabling complex data relationship management.
• Automatic schema checking and migration capabilities.

Troubleshooting Common Issues

If you encounter any issues while using Korm:

• Ensure you have properly configured database drivers.
• Check for typos in your struct definitions.
• Examine your connection strings for correctness.
• Look through console logs for any error messages during execution.
