How to Eager Load Specific Columns in Laravel 10

Today we will learn eager load specific columns in laravel 9 and laravel 10. We can make our query faster using the eager loading. I will show you how to get specific columns within eager load. We can use eager load while retriving the data from a relation. Let's explore an example to get specific columns with eager load.

Think you have two tables User and Post.  Now Define a relation inside User Model where each user has multiple posts.

namespace App\Models;


class User extends Authenticatable
{
    use HasApiTokens, HasFactory, Notifiable;
    
    public function user_posts()
    {
        return $this->hasMany(Post::class, 'user_id', 'id');
    }
}

Now eager load specific columns from User with user_post relation. Here we we will get id and title from posts table with eager load.

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use App\Models\User;

class ClientController extends Controller
{
    public function user_list_with_posts()
    {
        $user_lists = User::with('user_posts:id,title')->get()
        return $user_lists;
    }
}

In the above exmple we define id and title from user_posts relation while retriving the user lists. This the way we eager load specific columns in laravel eloquent relationships.
