What is a Laravel Observer? A Laravel Observer is a class that listens for specific events (such as creating, updating, deleting) on a model and performs actions in response to those events. When would you use Observers in Laravel? Observers are useful when you want to decouple the logic related to model events from the models themselves. They are particularly handy for maintaining clean, modular code and separating concerns. How do you create an Observer in Laravel? To create an Observer in Laravel, you typically use the make:observer Artisan command, which generates a new Observer class. You then define the event listeners (e.g., created , updated , deleted ) within that class. What are the differences between using Observers and using Model Events directly? Observers provide a cleaner and more organized way to handle model events compared to directly attaching listeners to model events. They promote better separation of concerns and make it easier to maintain and test your code. Ca...

 1. Challege 1 During the development of our booking features in Laravel, we encountered several challenges that required careful consideration and innovative solutions to overcome. One of the primary challenges we faced was the diversity in the structure of booking-related data, with different booking features having separate tables, some sharing similar structures, and others being entirely different. This fragmented data model made it difficult to implement a common service and enforce a consistent interface for request parameters. To address this challenge and promote code reusability and maintainability, we decided to leverage morphed relations in Laravel. By using morphed relations, we were able to abstract common functionalities and interfaces across different booking types, allowing for a more flexible and reusable codebase. However, as we progressed, we encountered performance issues when dealing with aggregated data for counts and totals of bookings, particularly when dis...

Relationships between database tables using Eloquent relationships (e.g., one-to-one, one-to-many, many-to-many). Eloquent events for hooking into model lifecycle events (e.g., creating, updating, deleting).
