Introduction

Laravel's naming conventions are essential for clean, maintainable, and scalable applications. By adhering to these standards across models, controllers, routes, migrations, views, and database schemas, developers can simplify collaboration and debugging. This guide provides a step-by-step hands-on explanation with examples for mastering these conventions.

1. Models

In Laravel, model names should be singular and in PascalCase. The convention is that the model class name should match the corresponding database table name in snake_case.

Example:

// Model: app/Models/BlogPost.php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class BlogPost extends Model
{
    protected $table = 'blog_posts'; // Convention is to use snake_case table names
}

• Model Class: BlogPost (singular, PascalCase).
• Table Name: blog_posts (plural, snake_case).

Explanation:

• The class BlogPost follows PascalCase, while the table it represents follows snake_case (blog_posts).
• By default, Laravel assumes the plural form of the model name as the table name, so BlogPost maps to blog_posts.

2. Controllers

Controller names should be in PascalCase and end with Controller.

Example:

// Model: app/Models/BlogPost.php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class BlogPost extends Model
{
    protected $table = 'blog_posts'; // Convention is to use snake_case table names
}

Explanation:

• The controller is named BlogPostController, which follows the convention of appending Controller to the model name in PascalCase.
• Methods like index() and show() follow the camelCase convention for method names.

Summary of Naming Conventions in Laravel:

1. Models: Singular, PascalCase (e.g., BlogPost).
2. Controllers: PascalCase, ending with Controller (e.g., BlogPostController).
3. Routes: Descriptive, snake_case (e.g., blog.index, blog.show).
4. Migrations: YYYY_MM_DD_HHMMSS_create_table_name.php, snake_case for table names (e.g., blog_posts).
5. Views: snake_case for file names (e.g., index.blade.php).
6. Database Columns: snake_case (e.g., author_name, published_at).
7. Validation Rules: camelCase for method names, snake_case for input keys.
