README

This laravel package helps you dynamically set more database configurations through the .env file or database.

REQUIREMENTS

STEPS TO INSTALL

composer require ikechukwukalu/dynamicdatabaseconfig

Introduction

The need for this package came up when I once handled an already existing project that, due to certain constraints, had 9 databases implemented for each country their application was being utilised. This application also had a central database that was used by every country as well.

The config/database file wasn’t pretty. I’d prefer to have all configurations within the .env file only. The Big question was, what if the databases required grew to 19? These were the problems, both pending and existing that needed a clean hack/solution.

Middlewares

• env.database.config
• dynamic.database.config

Env.database.config Middleware

This middleware fetches database configurations from the .env file using postfixes like ONE. This dynamically declares an additional database connection for your laravel application.

DB_HOST_ONE=127.0.0.1
DB_PORT_ONE=3306
DB_DATABASE_ONE=second_db
DB_USERNAME_ONE=root
DB_PASSWORD_ONE=

• Sample middleware implementation

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

/**
 * mysql is the type of relational database connection being replicated - $database
 * mysql_1 is the new connection name - $name
 * ONE is the postfix - $postfix
 */

Route::middleware(['env.database.config:mysql,mysql_1,ONE'])->group(function () {
    Route::post('/user', function (Request $request) {
        /**
         * $request->_db_connection === 'mysql_1'
         */
        return \App\Models\User::on('mysql_1')->find(1);
    });
});

Route::post('/user', function (Request $request) {
        /**
         * $request->_db_connection === 'mysql_1'
         */
        return \App\Models\User::on('mysql_1')->find(1);
})->middleware('env.database.config:mysql,mysql_1,ONE');

You would not need to add a postfix, ONE, parameter to the middleware for the $postFix variable if you simply set the following session value session(config('dynamicdatabaseconfig.session_postfix')), but when a postfix parameter has been set, it will be used instead of the session value.

Dynamic.database.config Middleware

This middleware fetches database configurations from the database_configurations table within the primary migration database. It utilises a unique $ref variable. It’s recommended that the unique $ref variable should be human readable, that way it becomes easier to run the package’s console commands for running migrations. This will also dynamically declare an additional database connection for your laravel application.

use Ikechukwukalu\Dynamicdatabaseconfig\Models\DatabaseConfiguration;

protected $hidden = [
        'ref',
        'name',
        'database',

        /**
         * Accepts only arrays
         */
        'configuration'
];

• Sample eloquent database insert

$countries = ['nigeria', 'ghana', 'togo', 'kenya'];
$config = \Config::get('database.connections.mysql');

foreach ($countries as $country) {
    $config['database'] = $country . '_db';
    DatabaseConfiguration::firstOrCreate(
    ['ref' => $country],
    [
        'ref' => $country,
        'name' => 'mysql_' . $country,
        'database' => 'mysql',
        'configuration' => $config
    ]);
}

• Sample middleware implementation

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

/**
 * nigeria is $ref value
 */

Route::middleware(['dynamic.database.config:nigeria'])->group(function () {
    Route::post('/user', function (Request $request) {
        /**
         * $request->_db_connection === 'mysql_nigeria'
         */
        return \App\Models\User::on('mysql_nigeria')->find(1);
    });
});

Route::post('/user', function (Request $request) {
        /**
         * $request->_db_connection === 'mysql_nigeria'
         */
        return \App\Models\User::on('mysql_nigeria')->find(1);
})->middleware('dynamic.database.config:nigeria');

You would not need to add a ref, nigeria, parameter to the middleware for the $ref variable if you simply set the following session value session(config('dynamicdatabaseconfig.session_ref')), but when a ref parameter has been set, it will be used instead of the session value.

By default, the values stored within the configuration field will be hashed, but you can adjust this from the .env file by setting DB_CONFIGURATIONS_HASH=false.

Migration

It’s compulsory to first migrate laravel’s initial database.

Other Migrations

• Default migrations
• Isolated migrations

Default Migrations

This will only migrate files within laravel’s default migration path database/migrations

php artisan env:migrate mysql mysql_1 ONE

php artisan dynamic:migrate nigeria

Isolated Migrations

This will only migrate files within the specified migration path database/migrations/folder

php artisan env:migrate mysql mysql_1 ONE --path=database/migrations/folder

php artisan dynamic:migrate nigeria --path=database/migrations/folder

Both Migrations

Running the migrations as displayed below will result in the respective database having the migrated data from migrations within database/migrations and database/migrations/folder.

php artisan env:migrate mysql mysql_1 ONE
php artisan env:migrate mysql mysql_1 ONE --path=database/migrations/folder

php artisan dynamic:migrate nigeria
php artisan dynamic:migrate nigeria --path=database/migrations/folder

Database Seeding

php artisan env:migrate mysql mysql_1 ONE --seed
php artisan env:migrate mysql mysql_1 ONE --seeder=DatabaseSeederOne
php artisan env:migrate mysql mysql_1 ONE --seeder=DatabaseSeederOne  --path=database/migrations/folder

php artisan dynamic:migrate nigeria --seed
php artisan dynamic:migrate nigeria --seeder=DatabaseSeederNigeria
php artisan dynamic:migrate nigeria --seeder=DatabaseSeederNigeria  --path=database/migrations/folder

Re-runing Migrations Afresh

php artisan env:migrate mysql mysql_1 ONE --fresh
php artisan env:migrate mysql mysql_1 ONE --fresh --seed
php artisan env:migrate mysql mysql_1 ONE --fresh --seeder=DatabaseSeederOne
php artisan env:migrate mysql mysql_1 ONE --path=database/migrations/folder --fresh
php artisan env:migrate mysql mysql_1 ONE --path=database/migrations/folder --fresh --seeder=DatabaseSeederOne

php artisan dynamic:migrate nigeria --fresh
php artisan dynamic:migrate nigeria --fresh --seed
php artisan dynamic:migrate nigeria --fresh --seeder=DatabaseSeederNigeria
php artisan dynamic:migrate nigeria --path=database/migrations/folder --fresh
php artisan dynamic:migrate nigeria --path=database/migrations/folder --fresh --seeder=DatabaseSeederNigeria

Refreshing Migrations

php artisan env:migrate mysql mysql_1 ONE --refresh
php artisan env:migrate mysql mysql_1 ONE --refresh --seed
php artisan env:migrate mysql mysql_1 ONE --refresh --seeder=DatabaseSeederOne
php artisan env:migrate mysql mysql_1 ONE --path=database/migrations/folder --refresh
php artisan env:migrate mysql mysql_1 ONE --path=database/migrations/folder --refresh --seeder=DatabaseSeederOne

php artisan dynamic:migrate nigeria --refresh
php artisan dynamic:migrate nigeria --refresh --seed
php artisan dynamic:migrate nigeria --refresh --seeder=DatabaseSeederNigeria
php artisan dynamic:migrate nigeria --path=database/migrations/folder --refresh
php artisan dynamic:migrate nigeria --path=database/migrations/folder --refresh --seeder=DatabaseSeederNigeria

Rolling Back Migrations

php artisan env:migrate mysql mysql_1 ONE --rollback
php artisan env:migrate mysql mysql_1 ONE --path=database/migrations/folder --rollback

php artisan dynamic:migrate nigeria --rollback
php artisan dynamic:migrate nigeria --path=database/migrations/folder --rollback

NOTE

• A primary database is needed before any other database can be migrated.
• A database will be created if it does not exist.
• Each database will retain it’s own independent migration table.
• It’s recommended that you do not publish the package’s migration file, unless you want the database_configurations table to be migrated into every extra database created when running Default migrations.

PUBLISH MIGRATIONS

• php artisan vendor:publish --tag=ddc-migrations

PUBLISH CONFIG

• php artisan vendor:publish --tag=ddc-config

Storing JSON data in a Laravel database provides a flexible solution for managing dynamic attributes or unstructured data. In this tutorial, we will walk through the process of storing JSON data in a Laravel database, using a practical example of storing product attributes. By the end of this tutorial, you will have a clear understanding of how to store and retrieve JSON data efficiently using Laravel.

Step 1: Setting up a Laravel Project

Create a new Laravel project using the following command:

laravel new json-data-storage

Step 2: Creating the Products Table Migration

Generate a migration file to create the products table using the command:

php artisan make:migration create_products_table --create=products

Inside the generated migration file (database/migrations/YYYY_MM_DD_create_products_table.php), define the table schema with a JSON column for the attributes:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->json('attributes');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('products');
    }
};

Step 3: Running the Migration

Run the migration using the following command:

php artisan migrate

Step 4: Creating the Product Model

Generate a Product model using the command:

php artisan make:model Product

In the Product model (app/Models/Product.php), add the $casts property to specify that the attributes attribute should be treated as JSON:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    use HasFactory;

    protected $casts = [
        'attributes' => 'json',
    ];
}

Step 5: Storing Product Attributes as JSON

To store product attributes as JSON, we can simply use Laravel’s Eloquent model. Create a new Product instance, set the desired attributes as an array, and save it:

use App\Models\Product;

$product = new Product;
$product->attributes = [
    'color' => 'red',
    'size' => 'medium',
    'weight' => 0.5,
];
$product->save();

Step 6: Retrieving JSON Data

To retrieve the attributes of a product, you can access the attributes property on the model:

$product = Product::find(1);
$attributes = $product->attributes;

If you want to access a specific attribute within the JSON data, you can do so by using array access:

$color = $product->attributes['color'];

By accessing the attributes property, you can retrieve the JSON data associated with the product and access specific attributes as needed.

Step 7: Manipulating JSON Data (Full Array)

To update all the attributes of the product at once, you can assign a new array with all the key-value pairs and use Eloquent’s save() method to update the record directly.

$product = \App\Models\Product::find(1);
$product->attributes = [
    'color' => 'green',
    'size' => 'large',
    'weight' => 2.5,
];
$product->save();

Step 8: Manipulating JSON Data (One Value)

Updating a single value within the JSON data requires a slightly different approach in Laravel and has one important caveat. Directly modifying the attribute like $product->attributes['weight'] = 1.0 and saving the product will result in an ErrorException: “Indirect modification of overloaded property App\Models\Product::$attributes has no effect.”

To overcome this issue, you can follow the solution below:

$product = \App\Models\Product::find(1);
$attributes = $product->attributes; // create a copy of the array
$attributes['weight'] = 0.6; // modify the value in the copied array
$product->attributes = $attributes; // assign the copied array back to $product->attributes
$product->save();

Conclusion

Storing JSON data in a database using Laravel provides flexibility and convenience when working with dynamic or unstructured data. By following the steps outlined in this tutorial, you have learned how to create the necessary migrations and models, store and retrieve JSON data, and manipulate the JSON data efficiently. This knowledge equips you with the tools to handle various use cases in your Laravel applications and opens up possibilities for efficiently managing complex data structures.

Start implementing JSON data storage in your Laravel projects and unlock the full potential of your application’s data management capabilities. Happy coding!
