Learn Laravel Scopes and simplify Eloquent Queries

In this article we learn how to use Laravel scopes from scratch  which you can reuse in a query and you don’t need to duplicate . Scopes in laravel allow you to define reusable query constraints that can be applied to queries on your models.It made code more organized, readable.We have two types of scopes , Local Scope and Global Scope.

Creating a Scope (Local Scope)

You can define a scope by adding a method to your Eloquent model. The method name should start with scope, followed by a meaningful name describing the scope's purpose.

 class Post extends Model
{
   // Scope to retrieve only published posts
    public function scopePublished($query)
    {
        return $query->where('published', true);
    }
}

Using a Scope

We can use it like any other Eloquent method when querying your model.

$publishedPosts = Post::published()->get();

Scopes can also accept parameters, allowing for dynamic behavior.

public function scopeStatus($query, $status)
{
    return $query->where('status', $status);
}

$draftPosts = Post::status('draft')->get();

Global Scopes

Global scopes automatically apply to all queries for a given model.

public static function booted()
{
    static::addGlobalScope('published', function ($query) {
        $query->where('published', true);
    });
}

Removing Scopes

if you need to temporarily remove a scope,this is how you can do that.

$posts = Post::withoutGlobalScope('published')->get();
