26) How do you implement relationships in Eloquent?  

Eloquent supports several types of relationships, including one to one, one to many, and many to many. You can define these relationships in the model using specific methods like `hasMany()`, `belongsTo()`, and `belongsToMany()`.

27) What is form request validation in Laravel?  

Form request validation allows you to create custom request classes for validating input data. It centralizes validation logic, making your controllers cleaner and more manageable by separating the validation rules from business logic.

28) Explain the difference between local and global scopes in Eloquent.  

Local scopes allow you to encapsulate common query logic within a model that can be applied at runtime, while global scopes apply certain constraints automatically to all queries performed on a model.

29) What are policies in Laravel?  

Policies are classes that organize authorization logic around a particular model or resource. They provide methods to determine whether a user can perform a given action on a resource, promoting a clearer and more maintainable code structure.

30) How do you create and use custom validation rules in Laravel?  

You can create custom validation rules by extending the `Rule` class or creating a new validation rule using an artisan command. Once created, you can use these rules within your form requests or validation logic.

31 - What are queued jobs in Laravel?  

Queued jobs allow you to defer processing tasks until later, improving application responsiveness. Jobs can be pushed onto a queue and processed asynchronously, which is useful for tasks like sending emails or processing uploaded files.

32) How do you access configuration values in Laravel?  

You can access configuration values using the `config()` helper function, allowing you to retrieve values from configuration files stored in the `config` directory, facilitating flexible and environment dependent configurations.

33) What are the differences between `$this >app['config']` and `config()`?  

`$this >app['config']` directly accesses the Application's service container, while `config()` is a global helper function that abstracts the access and is more commonly used in Laravel applications for its simplicity.

34) How do you enable and configure CORS in Laravel?  

CORS (Cross Origin Resource Sharing) can be configured in Laravel by using middleware, especially when you enable it via the `barryvdh/laravel cors` package, which allows you to specify which origins can access resources.

35) What is the purpose of the `database/factories` directory?
