How to Eager Loading Specific Columns in Laravel

Learn how to eager loading only specific columns in Laravel to prevent unnecessary column retrieval

Created on Jul 03, 2021


To eager load only specific column you can specify the relationship then add the column you want it to load after specifying a column ":" separated by a comma ",".

$books = User::with('achievements:id,name,achievement_id')->get();

Do note that you have to include the "id", "foreign key" and any necessary columns as this is one of the required for this type of eager load.

Relationship Definition
The relationship is defined like usual.

namespace App\Models;

class User extends Model
  public function achievements() {
    return $this->hasMany(Achievement::class);

Inverse Relationship
For the inverse relationship, it's defined like below.

namespace App\Models;

class Achievement extends Model
  public function user() {
    return $this->belongsTo(User::class);
