Implement configuration tracking architecture.

[nfebe]

How do we track for example "Default wallet" and "Default currency".....

[nfebe]

As part of this we can potentially implement, creating this defaults on registration.

[nfebe]

Mark essential categories? should be a config? somehow?

[nfebe]

Template for ideas. (This but it should be implemented with relationships)

🧱 1. Database Migration

Create a configurations table:

Schema::create('configurations', function (Blueprint $table) {
    $table->id();
    $table->foreignId('user_id')->nullable()->constrained()->onDelete('cascade');
    $table->string('key');
    $table->json('value')->nullable();
    $table->timestamps();

    $table->unique(['user_id', 'key']); // Ensure unique keys per user
});

📦 2. Model: Configuration.php

class Configuration extends Model
{
    protected $fillable = ['user_id', 'key', 'value'];

    protected $casts = [
        'value' => 'array',
    ];

    public static function getValue($key, $userId = null)
    {
        return static::where('key', $key)
            ->where('user_id', $userId)
            ->first()
            ?->value;
    }

    public static function setValue($key, $value, $userId = null)
    {
        return static::updateOrCreate(
            ['key' => $key, 'user_id' => $userId],
            ['value' => $value]
        );
    }
}

⚙️ 3. Usage Examples

During Registration

Configuration::setValue('default_wallet_id', $wallet->id, $user->id);
Configuration::setValue('default_currency', 'XAF', $user->id);
Configuration::setValue('essential_categories', ['food', 'transport'], $user->id);

Later in the App

$defaultWallet = Configuration::getValue('default_wallet_id', auth()->id());
$currency = Configuration::getValue('default_currency', auth()->id());

💡 Optional: Service Wrapper

Create a small config service:

class ConfigService
{
    public static function get($key)
    {
        return Configuration::getValue($key, auth()->id());
    }

    public static function set($key, $value)
    {
        return Configuration::setValue($key, $value, auth()->id());
    }
}

Usage:

ConfigService::get('default_currency');
ConfigService::set('default_wallet_id', $wallet->id);

✅ Notes

• Supports per-user settings; can easily extend to global or organization-wide by changing user_id to null or using account_id.
• Useful for any preferences that need to persist and be editable.
• Can be cached for speed if used frequently.
