What is Laravel Model Observers?

Laravel is one of the world’s most common PHP frameworks used to create web applications, from small to large projects. Because of its performance, features, and scalability, Laravel is a skilled developer’s choice. Laravel follows the MVC (Model View Controller) structure which makes the web applications easy to learn and to prototype quickly. Laravel takes the pain out of the development of web applications by offering built-in functionality such as authentication, fax, routing, sessions and the list continues. Laravel is so easy to customize that you can build your project structure that fits your web application’s demands. With the beautiful and elegant syntax of Laravel, you can write code that is self-explaining and concise, and make it compliant with the new web technologies. What is Laravel Model Observer? One of the greatest functions is Laravel System Observers. Observers are used to grouping the listeners of events to a pattern. System names for the Observers groups apply to the eloquent case you want to listen to. The model receives these methods as its only argument. Laravel does not have an observers default tab. There is also no regular artisan order to produce observers. Eloquent model fire several events which allow you to look at the following points in the life cycle of a model: Retrieved: after a record has been retrieved Creating: before a record has been created Created: after a record has been created Updating: before a record is updated Updated: after a record has been updated Saving: before a record is saved (either created or updated) Saved: after a record has been saved (either created or updated) Deleting: before a record is deleted or soft-deleted Deleted: after a record has been deleted or soft-deleted Restoring: before a soft-deleted record is going to be restored Restored: after a soft-deleted record has been restored Why we want to use Model Observer If we want to concatenate the string with the name of the category but then we don’t want to write the logic or function or code in the controller, we can use the Model Observer. It will automatically fire when creating or modifying or removing a new record. Limitations There are some limitations that you should bear in mind when using the Model Observer. If you are using saved or saved hooks, you can never call the save method for the layout. If you have a saved hook and want to call the save method then you can use the saving hook. If your logic has to call the save method of the model then reconsider your logic or stop using observers. Conclusion Model observers are a very powerful and useful feature but we must be used with care because they can make the codebase more maintainable but you need to be aware of their limitations.
