---

## Installation & Setup

### Prerequisites

Before installing the multi-tenant system, ensure you have:

- ✅ PHP 8.1 or higher
- ✅ Composer installed
- ✅ MySQL 8.0 or higher
- ✅ Node.js & NPM (for frontend assets)
- ✅ Git

### Step 1: Clone & Install Dependencies

```bash
# Clone the repository
git clone <repository-url>
cd solution-starterkit

# Install PHP dependencies
composer install

# Install NPM dependencies
npm install

# Build assets
npm run build
```

### Step 1.5: Install Tenancy Package (If Not Already Installed)

If you're setting up from scratch, install the Tenancy for Laravel package:

```bash
# Install tenancy package
composer require stancl/tenancy

# Run tenancy installation command
php artisan tenancy:install
```

This creates:
- ✅ `config/tenancy.php` - Configuration file
- ✅ `app/Providers/TenancyServiceProvider.php` - Service provider
- ✅ `routes/tenant.php` - Tenant routes file
- ✅ Tenant migration files

**Register the TenancyServiceProvider:**

Edit `bootstrap/providers.php`:

```php
return [
    App\Providers\AppServiceProvider::class,
    App\Providers\TenancyServiceProvider::class, // Add this
];
```

**Create Tenant Model:**

The Tenant model should already exist at `app/Models/Tenant.php`. Verify it has:

```php
<?php

namespace App\Models;

use Stancl\Tenancy\Database\Models\Tenant as BaseTenant;
use Stancl\Tenancy\Contracts\TenantWithDatabase;
use Stancl\Tenancy\Database\Concerns\HasDatabase;
use Stancl\Tenancy\Database\Concerns\HasDomains;

class Tenant extends BaseTenant implements TenantWithDatabase
{
    use HasDatabase, HasDomains;
    
    // Your custom fields and methods
}
```

**Configure Tenant Model:**

Edit `config/tenancy.php`:

```php
'tenant_model' => \App\Models\Admin\Tenant::class,
```

**Configure Central Domains:**

Edit `config/tenancy.php`:

```php
'central_domains' => [
    '127.0.0.1',
    'localhost',
    // Add your production domain
],
```

**Configure Database Prefix:**

Edit `config/tenancy.php`:

```php
'database' => [
    'prefix' => 'taskco-',
    // other settings...
],
```

### Step 2: Environment Configuration

```bash
# Copy environment file
cp .env.example .env

# Generate application key
php artisan key:generate

# Configure database in .env
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=taskco_central
DB_USERNAME=root
DB_PASSWORD=your_password

# Configure tenancy settings
TENANCY_DATABASE_PREFIX=taskco-
```

### Step 3: Database Setup

```bash
# Create central database
mysql -u root -p -e "CREATE DATABASE taskco_central;"

# Run central migrations and seeders
php artisan migrate:fresh --seed
```

This creates:
- ✅ **Normalized tenant tables (7 tables):**
  - `tenants` - Core info
  - `tenant_business_information` - Business details
  - `tenant_subscriptions` - Plans & billing
  - `tenant_limits` - Quotas & permissions
  - `tenant_contacts` - Contact persons
  - `tenant_settings` - Preferences
  - `tenant_metadata` - Notes & custom data
- ✅ **Normalized domain tables (5 tables):**
  - `domains` - Domain info
  - `domain_ssl_configs` - SSL certificates
  - `domain_dns_records` - DNS verification
  - `domain_redirect_settings` - Redirects
  - `domain_metadata` - Domain notes
- ✅ `sessions`, `cache`, `jobs` tables
- ✅ Central infrastructure

**Important: Tenant Migrations**

Move tenant-specific migrations to `database/migrations/tenant/` folder:

```bash
# Create tenant migrations folder if it doesn't exist
mkdir -p database/migrations/tenant

# Move user-related migrations to tenant folder
# Example: move users table migration
mv database/migrations/0001_01_01_000000_create_users_table.php \
   database/migrations/tenant/
```

**Why?** Tenant migrations run automatically when a tenant is created, thanks to the `TenancyServiceProvider` event system.

**Tenancy Event System:**

The `app/Providers/TenancyServiceProvider.php` maps events to jobs:

```php
// When a tenant is created
TenantCreated::class => [
    JobPipeline::make([
        CreateDatabase::class,      // 1. Create tenant database
        MigrateDatabase::class,      // 2. Run tenant migrations
        // SeedDatabase::class,      // 3. Optional: Seed data
    ])->send(function (TenantCreated $event) {
        return $event->tenant;
    })->shouldBeQueued(false),
],
```

This ensures:
1. Database is created first
2. Then migrations run
3. Then seeding (if enabled)
4. All in the correct order

### Step 4: File Permissions

```bash
# Set proper permissions
chmod -R 775 storage bootstrap/cache
chown -R www-data:www-data storage bootstrap/cache

# Or for development
chmod -R 777 storage bootstrap/cache
```

### Step 5: Configure Web Server

#### Apache Configuration

```apache
<VirtualHost *:80>
    ServerName localhost
    ServerAlias *.localhost
    DocumentRoot /var/www/taskco.site/solution-starterkit/public

    <Directory /var/www/taskco.site/solution-starterkit/public>
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/taskco-error.log
    CustomLog ${APACHE_LOG_DIR}/taskco-access.log combined
</VirtualHost>
```

#### Nginx Configuration

```nginx
server {
    listen 80;
    server_name localhost *.localhost;
    root /var/www/taskco.site/solution-starterkit/public;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-Content-Type-Options "nosniff";

    index index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location = /favicon.png { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    error_page 404 /index.php;

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~ /\.(?!well-known).* {
        deny all;
    }
}
```

### Step 6: Routes Configuration

**Central Routes:**

Ensure central routes are only accessible on central domains. Edit `routes/web.php`:

```php
// routes/web.php
foreach (config('tenancy.central_domains') as $domain) {
    Route::domain($domain)->group(function () {
        // Your central routes here
        Route::get('/', function () {
            return view('welcome');
        });
    });
}
```

**Tenant Routes:**

Tenant routes are in `routes/tenant.php` and use special middleware:

```php
// routes/tenant.php
Route::middleware([
    'web',
    InitializeTenancyByDomain::class,
    PreventAccessFromCentralDomains::class,
])->group(function () {
    Route::get('/', function () {
        return 'Tenant: ' . tenant('id');
    });
});
```

The middleware ensures:
- `InitializeTenancyByDomain` - Identifies tenant by domain
- `PreventAccessFromCentralDomains` - Blocks access from central domains

### Step 7: Module Configuration

```bash
# Check module status
php artisan module:list

# Enable required modules
php artisan module:enable Theme

# Verify modules_statuses.json
cat modules_statuses.json
```

Expected output:
```json
{
    "Theme": true
}
```

### Step 7: Verify Installation

```bash
# Check if everything is working
php artisan about

# Test database connection
php artisan tinker --execute="
echo 'Database: ' . \DB::connection()->getDatabaseName() . PHP_EOL;
echo 'Tables: ' . count(\DB::select('SHOW TABLES')) . PHP_EOL;
"

# List available commands
php artisan list tenant
php artisan list module
```

### Step 8: Start Development Server

```bash
# Start Laravel development server
php artisan serve

# Or specify host and port
php artisan serve --host=0.0.0.0 --port=8000
```

Access: `http://localhost:8000`

### Step 9: Create First Test Tenant

```bash
# Via API
curl -X POST http://localhost:8000/create-tenant \
  -H "Content-Type: application/json" \
  -d '{"tenant_id": "test-tenant", "company_name": "Test Company"}'

# Verify creation
php artisan tenants:list
```

### Step 10: Access Test Tenant

```bash
# Add to hosts file
sudo sh -c 'echo "127.0.0.1  test-tenant.localhost" >> /etc/hosts'

# Access in browser
http://test-tenant.localhost:8000

# Login credentials
Email: admin@example.com
Password: password
```

## Quick Start

### 1. Initial Setup (One Time)

```bash
# Run central migrations and seeders
php artisan migrate:fresh --seed
```

This creates:
- **12 normalized tables** (7 tenant tables + 5 domain tables)
- `sessions`, `cache`, `jobs` tables
- Complete normalized database structure

### 2. Create Your First Tenant

**Option A: Via API (Recommended)**

```bash
curl -X POST http://localhost:8000/create-tenant \
  -H "Content-Type: application/json" \
  -d '{
    "tenant_id": "my-company",
    "company_name": "My Company Inc",
    "email": "admin@mycompany.com",
    "plan": "pro"
  }'
```

**Option B: Via Command Line**

```bash
# Create tenant
php artisan tinker --execute="
\$t = \App\Models\Tenant::create(['id' => 'my-company']);
\$t->domains()->create(['domain' => 'mycompany.localhost']);
"

# Setup tenant (migrations + modules + seeding)
php artisan tenant:full-setup my-company
```

### 3. Access Your Tenant

```bash
# Add to hosts file
sudo sh -c 'echo "127.0.0.1  my-company.localhost" >> /etc/hosts'

# Start server
php artisan serve

# Access in browser
http://my-company.localhost:8000

# Login credentials
Email: admin@example.com
Password: password
```

### Using the Relationships

```php
// Get tenant with all related data
$tenant = Tenant::with([

## Module System

### How Modules Work

Modules are automatically detected and migrated in tenant context:

```php
// In TenantFullSetupCommand.php

$modules = Module::allEnabled(); // Gets from modules_statuses.json

$tenant->run(function () use ($modules) {
    foreach ($modules as $module) {
        Artisan::call('module:migrate', ['module' => $module->getName()]);
    }
});
```

### Module Structure

```
Website/Theme/
├── app/
│   └── Models/
│       ├── ThemeCategory.php
│       ├── ThemeOption.php
│       └── UserTheme.php
├── database/
│   ├── migrations/
│   │   ├── 2025_11_02_104753_create_theme_categories_table.php
│   │   ├── 2025_11_02_104917_create_theme_options_table.php
│   │   └── 2025_11_03_040543_create_user_themes_table.php
│   └── seeders/
│       └── CategoryWiseSeeder.php
├── module.json
└── composer.json
```

### Module Migration Example

```php
// Website/Theme/database/migrations/create_theme_categories_table.php

public function up(): void
{
    // This runs in TENANT database (taskco-{tenant-id})
    Schema::create('theme_categories', function (Blueprint $table) {
        $table->id();
        $table->string('name');
        $table->string('slug')->unique();
        $table->text('description')->nullable();
        $table->boolean('is_active')->default(true);
        $table->timestamps();
    });
}
```

### Enabling/Disabling Modules

Edit `modules_statuses.json`:

```json
{
    "Theme": true,
    "Productivity": true,
    "CustomModule": false
}
```

Or use commands:

```bash
php artisan module:enable Theme
php artisan module:disable Theme
```

## Workflows

### Workflow 1: Create New Tenant

```bash
# 1. Run central migrations (one time)
php artisan migrate:fresh --seed

# 2. Create tenant via API
curl -X POST http://localhost:8000/create-tenant \
  -H "Content-Type: application/json" \
  -d '{"tenant_id": "new-company", "company_name": "New Company Inc"}'

# 3. Add to hosts file
sudo sh -c 'echo "127.0.0.1  new-company.localhost" >> /etc/hosts'

# 4. Access tenant
http://new-company.localhost:8000
```

### Workflow 2: Add New Feature to Existing Tenants

```bash
# 1. Create migration
php artisan make:migration create_departments_table

# 2. Move to tenant folder
mv database/migrations/*_create_departments_table.php database/migrations/tenant/

# 3. Create seeder
php artisan make:seeder DepartmentSeeder

# 4. Run for all tenants
php artisan tenants:migrate
php artisan tenants:seed --class=DepartmentSeeder
```

### Workflow 3: Add New Module Feature

```bash
# 1. Create module migration
php artisan module:make-migration create_theme_settings_table Theme

# 2. Create module seeder
php artisan module:make-seed ThemeSettingSeeder Theme

# 3. Run for all tenants
php artisan tenants:run "artisan module:migrate Theme"
php artisan tenants:run "artisan module:seed Theme"
```

### Workflow 4: Update Existing Tenant

```bash
# 1. Create migration for new field
php artisan make:migration add_phone_to_users_table
mv database/migrations/*_add_phone_to_users_table.php database/migrations/tenant/

# 2. Run for specific tenant
php artisan tenants:migrate --tenants=acme

# 3. Or run for all tenants
php artisan tenants:migrate
```

---

## Best Practices

### 1. Always Use Central Migrations First

```bash
# Good ✅
php artisan migrate:fresh --seed  # Central
php artisan tenant:full-setup acme  # Tenant

# Bad ❌
php artisan tenant:full-setup acme  # Without central migrations
```

### 2. Use Appropriate Plans

```json
{
  "plan": "basic",      // 10 users, 1GB
  "plan": "pro",        // 50 users, 10GB
  "plan": "enterprise"  // 500+ users, 50GB+
}
```

### 3. Set Trial Periods

```php
$tenant->trial_ends_at = now()->addDays(14);
$tenant->status = 'trial';
$tenant->save();
```

### 4. Use Soft Deletes

```php
// Soft delete (recoverable)
$tenant->delete();

// Restore
$tenant->restore();

// Permanent delete
$tenant->forceDelete();
```

### 5. Backup Before Major Changes

```bash
# Backup all tenant databases
php artisan tinker --execute="
\App\Models\Tenant::all()->each(function(\$tenant) {
    \$dbName = 'taskco-' . \$tenant->id;
    exec('mysqldump -u root -p\$PASSWORD ' . \$dbName . ' > backups/' . \$tenant->id . '.sql');
});
"
```

### 6. Monitor Resource Usage

```php
// Check tenant users
$tenant->run(function() {
    $userCount = \App\Models\User::count();
    $maxUsers = $tenant->max_users;
    
    if ($userCount >= $maxUsers) {
        // Notify admin or upgrade plan
    }
});
```

### 7. Use Validation in Production

```php
// Add authentication to API routes
Route::middleware(['auth', 'admin'])->group(function () {
    Route::post('create-tenant', ...);
    Route::delete('delete-tenant/{id}', ...);
});
```

---

## Troubleshooting

### Issue: Module migrations not running

**Cause:** Module not enabled in `modules_statuses.json`

**Solution:**
```bash
php artisan module:enable Theme
# Or edit modules_statuses.json manually
```

### Issue: Foreign key constraint error

**Cause:** Module migrations running before tenant migrations

**Solution:** Module migrations run AFTER tenant migrations automatically. Ensure migrations are in correct folder:
- Tenant migrations: `database/migrations/tenant/`
- Module migrations: `Website/*/database/migrations/`

### Issue: CSRF token mismatch

**Cause:** Test routes need CSRF exclusion

**Solution:** Already configured in `bootstrap/app.php`:
```php
$middleware->validateCsrfTokens(except: [
    'create-tenant',
    'list-tenants',
    'delete-tenant/*',
]);
```

### Issue: Database not found

**Cause:** Tenant database doesn't exist

**Solution:**
```bash
# Run full setup to create database
php artisan tenant:full-setup {tenant-id}
```

### Issue: Permission denied

**Cause:** File permissions

**Solution:**
```bash
chmod -R 775 storage bootstrap/cache
chown -R www-data:www-data storage bootstrap/cache
```
