🧬 Laravel Migration Model Sync

Laravel Migration Model Sync is a development tool that automatically generates or synchronizes Eloquent model files based on your migration files. It extracts columns, data types, and foreign key relationships and applies them directly to your model"s $fillable, $casts, and relationship methods.

🚀 Features

• 🔄 Sync existing models: Adds missing $fillable, $casts, and relationships
• 🧱 Generate new models: Creates clean models directly from migrations
• 🧠 Smart relationship inference:
  • belongsTo from foreign keys
  • hasMany, hasOne, and belongsToMany
• 🗃 Supports both Laravel default and custom migration styles
• 📁 Easily configurable via config/modelsync.php
• ✨ Sync all models: A new model:sync-all command to synchronize all models from available migration files.
• 🛠 Generate migrations from models: model:generate-migration User — creates a migration file for a specific model
• 🛠 Generate migrations from models: model:generate-migrations — auto-generates all migration files from models (with dependency-aware sorting)

📦 Installation

Laravel versions supported: 8.x – 12.x

1. If using from Packagist:

composer require khairy/migration-model-sync

2. Publish the Configuration

php artisan vendor:publish --tag=modelsync-config

This creates the config file: config/modelsync.php

⚙️ Configuration

Edit config/modelsync.php to customize behavior:

return [
    \"model_path\" => app_path(\"Models\"),

    \"ignore_columns\" => [
        \"created_at\",
        \"updated_at\",
    ],

    \"relationship_overrides\" => [
        // \"created_by\" => \"belongsTo:App\\Models\\User\"
    ],
];

• model_path: Specifies the directory where generated models will be stored. By default, this is app/Models.
• ignore_columns: An array of column names that should be excluded from the $fillable and $casts properties of the generated models. Common examples include created_at and updated_at.
• relationship_overrides: Allows you to manually define or override specific relationship definitions for models. This is useful for complex or non-standard relationships that cannot be automatically inferred.

🧪 Usage

Sync a single model

php artisan model:sync User

This command will:

• Parse the migration that created users table
• Add $fillable, $casts, and any belongsTo relationships to app/Models/User.php

Sync all models

php artisan model:sync-all

This command will:

• Iterate through all migration files that create tables
• Parse each migration to extract schema information
• Generate or update the corresponding Eloquent model with $fillable, $casts, and inferred belongsTo relationships.

Generate migration file from model class

php artisan model:generate-migration User

This command will:

• Read app/Models/User.php
• Extract $fillable, $casts, and any belongsTo() relationships
• Infer column types (string, timestamp, json, etc.)
• Generate a create_users_table.php migration in database/migrations
• Include foreignId()->constrained()->on(...) if belongsTo() is present
• Automatically add timestamps and soft deletes if applicable

Generate migration files from model classs

php artisan model:generate-migrations

This command will:

• Loop through all model classes in app/Models/
• Read their $fillable, $casts, and belongsTo() methods
• Generate new create_*_table.php migration files
• Sort migrations by relationship dependency (by default)
• Automatically set timestamps to maintain migration order
• Use options like --only=User,Post , --except=Log , --sort=none , and --force for advanced control.

Example Migration

Schema::create(\"profiles\", function (Blueprint $table) {
    $table->id();
    $table->string(\"name\");
    $table->string(\"email\");
    $table->timestamp(\"email_verified_at\")->nullable();
    $table->string(\"password\");
    $table->foreignId(\"user_id\")->constrained();
    $table->timestamps();
});

Resulting Model

namespace App\\Models;

use Illuminate\\Database\\Eloquent\\Model;

class Profile extends Model
{
    protected $fillable = [\"name\", \"email\", \"email_verified_at\", \"password\", \"user_id\"];

    protected $casts = [
        \"email_verified_at\" => \"datetime\",
        \"created_at\" => \"datetime\",
        \"updated_at\" => \"datetime\",
    ];

    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

💡 How Relationships Are Inferred

| Relation Type | Detection Logic | |----------------|----------------------------------------------------------------------------------| | belongsTo | foreignId(\"user_id\")->constrained() or foreign key chains | | hasMany | Inferred from other tables containing a foreign key to this model (todo) | | hasOne | Inferred from profiles, settings, etc. (todo) | | belongsToMany | Detected from pivot tables like role_user (todo) |

🧩 Extending the Package

You can override default behavior:

• Use relationship_overrides in config to manually define model relations
• You can also stub and customize the model template (coming soon)
