In the dynamic world of web development, Laravel has emerged as a dominant force. It provides developers with robust and elegant features to build sophisticated applications. With each new iteration, Laravel introduces innovative features that enhance the development experience. One such feature that has garnered attention in Laravel 10 is the oldestOfMany relationship method. We already discussed the latestOfMany, hasOne, hasMany, and belongsTo relationship in Laravel 10. But, today, in this article, we will dive deep into the essence of the oldestOfMany relationship. We will understand its importance in application development. Also, will explore how to effectively implement it in the project. The relationships allow you to establish connections between models. It helps to find specific records based on predefined conditions. By utilizing this powerful feature, you can unlock the true potential of your Laravel applications.
Before moving ahead, let’s take a glimpse of what is the oldestOfMany relationship.
Introduction to oldestOfMany Relationships and its Importance
The oldestOfMany relationship, as the name suggests, helps you fetch the oldest related record. In other words, when you have a collection of records then you can fetch the oldest one using this relation. By utilizing the oldestOfMany relationship effectively, you can significantly enhance your Laravel applications. This especially focuses on retrieving the oldest related record from a set of multiple related records. This offers a unique perspective on data retrieval. Also, it opens new possibilities for analyzing time-based data.
Use Cases for Implementing oldestOfMany Relationships
You can create and use this relationship in various scenarios. Some common use cases include:
- Analyzing customer transaction histories by retrieving the first transaction made.
- Keeping track of the initial registration date of users in a multi-user system.
- Accessing the oldest entry in a log of events for auditing purposes and many more.
By using this relationship, you can add valuable functionality to your Laravel applications. Which enhances the overall user experience.
Before moving ahead, let’s understand, what we are going to build in this post.
We are going to achieve the below result using the oldestOfMany relation in Laravel 10.
Therefore, let’s move out to the implementation of this functionality quickly.
Prerequisites
To implement this functionality in a Laravel 10 application, you will require the below configurations in your system.
- PHP >=8.1
- Composer
- Apache/Nginx Server
- VS Code Editor (Optional)
- MySQL (version > 5)
Once you are done with the above, let’s start by creating a new application.
Step 1 – Create a Project For oldestOfMany Relation in Laravel 10
We are going to set up a Laravel 10 application. However, this step is not mandatory. You can proceed with the existing project setup of Laravel 10 as well.
composer create-project --prefer-dist laravel/laravel relation-appAfter the project setup, you will have to configure the database. So, I am not going to repeat that step here. We will directly jump to the main functionality implementation.
Step 2 – Create Models and Migrations in Laravel 10
You will require two models and migrations to establish this relation in Laravel. Hence, let’s create them one by one. But, for simplicity, I will be using the default User model and migration in this post.
However, you can create a separate if it is required for you. Ony, I will need to create the second model and migration.
php artisan make:model Todo -mSo, using the above command, I have created this.
After that, let’s proceed with the schema in the migrations.
Step 3 – Add Schema and Fillable Properties
I am considering, that you have these two migrations ready. One for users and another for the todos. Hence, let’s add the below schema inside those.
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration
{
/**
* Run the migrations.
*/
public function up(): void
{
Schema::create('users', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*/
public function down(): void
{
Schema::dropIfExists('users');
}
};After that, you have to add the schema in the todos table.
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration
{
/**
* Run the migrations.
*/
public function up(): void
{
Schema::create('todos', function (Blueprint $table) {
$table->id();
$table->unsignedBigInteger('user_id');
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
$table->string('title')->nullable();
$table->text('description')->nullable();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*/
public function down(): void
{
Schema::dropIfExists('todos');
}
};Now, after adding the schemas, you will have to migrate these.
php artisan migrateThereafter, you need to add fillable properties to the models. Hence, start it from the User model.
<?php
namespace App\Models;
// use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Sanctum\HasApiTokens;
class User extends Authenticatable
{
use HasApiTokens, HasFactory, Notifiable;
/**
* The attributes that are mass assignable.
*
* @var array<int, string>
*/
protected $fillable = [
'name',
'email',
'password',
];
/**
* The attributes that should be hidden for serialization.
*
* @var array<int, string>
*/
protected $hidden = [
'password',
'remember_token',
];
/**
* The attributes that should be cast.
*
* @var array<string, string>
*/
protected $casts = [
'email_verified_at' => 'datetime',
'password' => 'hashed',
];
}Similarly, you will have to add in the Todo model.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Todo extends Model
{
use HasFactory;
protected $fillable = [
'user_id',
'title',
'description'
];
}Next, you will have to create the oldestOfMany relation in Laravel 10.
Step 4 – Create the oldestOfMany Relationship in Laravel 10
Firstly, you will have to navigate to the parent model (User) because we have defined primary and foreign keys in the migrations.
Therefore, add the below relation to the User model.
/**
* Function : Relation for oldest todo
* @relationType: oldestOfMany
* @return
*/
public function oldestTodo() {
return $this->hasOne(Todo::class, 'user_id', 'id')->oldestOfMany();
}In order to define the oldestOfMany relation in Laravel, you will need a hasOne relation. So, take a look at the above snippet. I have created a hasOne relation and used the oldestOfMany relation to fetch the oldest post.
After adding this relation to the model, the User model will look like this.
<?php
namespace App\Models;
// use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Sanctum\HasApiTokens;
class User extends Authenticatable
{
use HasApiTokens, HasFactory, Notifiable;
/**
* The attributes that are mass assignable.
*
* @var array<int, string>
*/
protected $fillable = [
'name',
'email',
'password',
];
/**
* The attributes that should be hidden for serialization.
*
* @var array<int, string>
*/
protected $hidden = [
'password',
'remember_token',
];
/**
* The attributes that should be cast.
*
* @var array<string, string>
*/
protected $casts = [
'email_verified_at' => 'datetime',
'password' => 'hashed',
];
/**
* Function : Relation for oldest todo
* @relationType: latestOfMany
* @return
*/
public function oldestTodo() {
return $this->hasOne(Todo::class, 'user_id', 'id')->oldestOfMany();
}
}That’s done for the relation and model configuration. Next, you will require some data based on the schemas we have created.
I have created the fake data using the factory class and dumped it in the tables using the seeder.
Hence, let’s take a look at the data shown in the below screenshots.
Here, in the table, I have created 3 todos against every user as shown below.
After that, you will have to create a controller for fetching these data.
Step 5 – Create a Controller For Retrieving Records With oldestOfMany Relationship
Techniques for Retrieving Specific Records Using oldestOfMany Relationships
Retrieving specific records based on oldestOfMany relationships involves utilizing Laravel’s querying capabilities and relationship methods. You can apply conditions, sort the results, or utilize additional query modifiers to fine-tune the retrieval process. By combining these techniques, you can efficiently retrieve the desired records from the oldestOfMany relationship.
Query Optimization for Efficient Data Retrieval
Now, let’s talk about query optimization when working with large datasets. The optimization of your queries becomes crucial for efficient data retrieval. You will have to utilize techniques such as eager loading, indexing, and pagination to enhance the performance of your oldestOfMany relationship queries. These optimizations will ensure that your application responds quickly and scales effectively.
Now, let’s move the functionality part. So, firstly you will require a controller in order to fetch the data from the model.
Hence, create it using the below command.
php artisan make:controller UserControllerWe have the controller ready now. Therefore, we can add functionality to it.
<?php
namespace App\Http\Controllers;
use App\Models\User;
use Illuminate\Http\Request;
class UserController extends Controller
{
/**
* Function : Fetch Users with Oldest Todo
* @param NA
* @return response
*/
public function index() {
$users = User::with('oldestTodo')->get();
return view('user-todos', compact('users'));
}
}In the above function, I have fetched all the users with the oldestTodo relation. Then I returned this to view for displaying the data.
Hence, thereafter, you will have to create a view with the same name.
Step 6 – Create a View For Rendering Data
To create a view, firstly, you have to navigate to the views folder. After that create a blade file with the name user-todos.blade.php.
After that let’s add the HTML snippet for displaying the data.
<!doctype html>
<html lang="en">
<head>
<title>Oldest of Many Relationship in Laravel 10</title>
<meta charset="utf-8">

</body>
</html>Here, we have rendered the data to the view.
But, now, we have to create a route for pointing out the controller function. Hence, let’s create a route for it.
Step 7 – Create a Route in Laravel 10
To add the route, you will have to navigate to the web.php and then add the below route inside it.
<?php
use App\Http\Controllers\UserController;
use Illuminate\Support\Facades\Route;
Route::get('users', [UserController::class, 'index']);
That’s it for the functionality. Now, you are ready to serve the application and see the result.
But the post is not finished yet. Something is missing related to performance optimization and query optimization things.
Therefore, let’s understand that.
Performing Updates on Related Records
In some cases, you might need to update related records within an oldestOfMany relationship. Laravel offers convenient methods to accomplish this, allowing you to make changes to the oldest related record while keeping the relationship intact. This flexibility empowers you to maintain data consistency and make necessary updates efficiently.
Managing Cascading Deletions and Constraints with oldestOfMany Relationships
Cascading deletions and constraints are vital considerations when working with oldestOfMany relationships. Laravel provides mechanisms to handle such scenarios effectively. Also, It allows you to define cascading deletions for related records or enforce constraints to maintain data integrity. Therefore, by managing these aspects properly, you can ensure the reliability and accuracy of your data.
