Let’s Understand How Laravel Eloquent Works

The PHP Laravel framework is packaged with the Eloquent Object Relational Mapper (ORM), which provides an extremely easy way to communicate with a database. As developers need to create complex websites and other applications, they prefer a hassle-free and shorter development time.

Laravel Development Services is faster and provides an adequate solution to most problems encountered. Varying business requirements are addressed with faster development, as well as well-organized, reusable, maintainable and scalable code. It works with custom web applications as it can cater to multiple databases and perform common database operations.

How does Eloquent Work :

Developers can work in Eloquent with multiple databases efficiently using an ActiveMethod implementation. It is an architectural pattern where the model created in the Model-View-Controller (MVC) structure corresponds to a table in the database.

The advantage is for models to perform common database operations without coding lengthy SQL queries. Models allow data querying in your tables, as well as inserting new records into tables. The process of synchronizing multiple databases running on different systems is simplified. There is no need to write SQL queries at all. All you have to do is to define database tables and relations between them, and Eloquent will do the rest of the job.

Laravel setup :

To fully appreciate the utility of Eloquent ORM, understanding the ecosystem is a must. Here are the steps to get started :

  1. Install Laravel from getcomposer.org
  2. Create migrations using Artisan console
  3. Create Eloquent models
  4. Seed the database

Artisan Console is the name of the command-line interface packaged with Laravel. It provides a number of helpful commands to be used during the development of your application. It is driven by the powerful Symfony Console component.

To view a list of all available Artisan commands, you may use the list command:

php artisan list

All the commands come with a concise description of its arguments and options. This is shown in a “help” screen. To view a help screen, simply precede the name of the command with “help” as shown:

php artisan help migrate

Migration :

Migration is a process of managing your database by writing PHP rather than SQL. Also, it provides a way of adding version control to your database. Assuming that our database is up and running. To get started with migrations, you need to setup Laravel migration. Open the terminal and choose the correct path, and you can use artisan to create that migration table with this command:

php artisan migrate:install

To create a migration, just run the following command:

php artisan make:migration create_student_records

Defining Eloquent models :

After you are done with the migration of your database, the next process is the seeding. Eloquent comes into the picture since seeding is inserting records into our database. Thus you will need to create your models before you can seed the database. Each database table has a corresponding model that is used to interact with that table. Models allow you to query for data in your tables, as well as insert new records into the table.

Seeders :

Many get confused with seeders but it is simply a class that populates your database. The good thing with seeders is that they can be executed using a simple command to refresh your database. It helps in eradicating unreadable names such as “pkshjkud” that may lead to overlooking some bugs.

The basic idea behind seeders is to help the problem of “dirty data” where one can develop a simple or even a powerful seeder. Overall seeders are a special set of classes that allow us to populate our database over and over with the same exact data.

CRUD with Eloquent :

CRUD operations under the Eloquent object-relational mapper (ORM) make it easier for Laravel developers to work with multiple databases. It performs create, retrieve, update, and delete (CRUD) operations, as well as maps object models to database tables. It handles all the database interaction required for CRUD operations.

Conclusion :

Laravel is considered a famous and robust PHP framework. Laravel with Eloquent provides competitive technology for web applications. Also, Retrace is a powerful tool for tracking the performance of applications built in PHP.
