## 🚀 **Quick Start**

### Installation

```bash
# Install with pip (pre-built wheels available)
pip install oxen-orm

# Or build from source
git clone https://github.com/Diman2003/OxenORM.git
cd OxenORM
pip install -e .
```

### Basic Usage

```python
import asyncio
from oxen import Model, IntegerField, CharField, connect

# Define your models
class User(Model):
    id = IntegerField(primary_key=True)
    name = CharField(max_length=100)
    email = CharField(max_length=255, unique=True)

async def main():
    # Connect to database
    await connect("postgresql://user:pass@localhost/mydb")
    
    # Create tables
    await User.create_table()
    
    # Create records
    user = await User.create(name="John Doe", email="john@example.com")
    
    # Query records
    users = await User.filter(name__icontains="John")
    for user in users:
        print(f"Found user: {user.name}")
    
    # Update records
    await user.update(name="Jane Doe")
    
    # Delete records
    await user.delete()

# Run the async function
asyncio.run(main())
```

### Advanced Features

```python
# Multi-database support
from oxen import MultiDatabaseManager

async def multi_db_example():
    manager = MultiDatabaseManager({
        'primary': 'postgresql://user:pass@localhost/primary',
        'analytics': 'mysql://user:pass@localhost/analytics',
        'cache': 'sqlite://:memory:'
    })
    
    # Use different databases for different models
    await User.objects.using('primary').create(name="User")
    await AnalyticsEvent.objects.using('analytics').create(event="page_view")

# Complex queries with advanced features
users = await User.filter(
    age__gte=18,
    email__icontains="@gmail.com"
).exclude(
    is_active=False
).order_by('-created_at').limit(10)

# Advanced field types
class Post(Model):
    id = IntegerField(primary_key=True)
    title = CharField(max_length=200)
    tags = ArrayField(element_type="text")  # PostgreSQL array
    metadata = JSONBField()  # PostgreSQL JSONB
    location = GeometryField()  # PostgreSQL geometry
    file = FileField(upload_to="uploads/")  # File handling
    image = ImageField(upload_to="images/")  # Image processing

# Window functions and CTEs
from oxen.expressions import WindowFunction, CommonTableExpression

# Window function
ranked_users = await User.annotate(
    rank=WindowFunction("ROW_NUMBER()", order_by=["created_at DESC"])
).filter(rank__lte=10)

# Common Table Expression
cte = CommonTableExpression("user_stats", User.aggregate(total=Count('id')))
```

\ud83d\ude80 **Quick Start**\n\n### Installation\n\n```bash\n# Install with pip (pre-built wheels available)\npip install oxen-orm\n\n# Or build from source\ngit clone https://github.com/Diman2003/OxenORM.git\ncd OxenORM\npip install -e .\n```\n\n### Basic Usage\n\n```python\nimport asyncio\nfrom oxen import Model, IntegerField, CharField, connect\n\n# Define your models\nclass User(Model):\n    id = IntegerField(primary_key=True)\n    name = CharField(max_length=100)\n    email = CharField(max_length=255, unique=True)\n\nasync def main():\n    # Connect to database\n    await connect(\"postgresql://user:pass@localhost/mydb\")\n    \n    # Create tables\n    await User.create_table()\n    \n    # Create records\n    user = await User.create(name=\"John Doe\", email=\"john@example.com\")\n    \n    # Query records\n    users = await User.filter(name__icontains=\"John\")\n    for user in users:\n        print(f\"Found user: {user.name}\")\n    \n    # Update records\n    await user.update(name=\"Jane Doe\")\n    \n    # Delete records\n    await user.delete()\n\n# Run the async function\nasyncio.run(main())\n```\n\n### Advanced Features\n\n```python\n# Multi-database support\nfrom oxen import MultiDatabaseManager\n\nasync def multi_db_example():\n    manager = MultiDatabaseManager({\n        'primary': 'postgresql://user:pass@localhost/primary',\n        'analytics': 'mysql://user:pass@localhost/analytics',\n        'cache': 'sqlite://:memory:'\n    })\n    \n    # Use different databases for different models\n    await User.objects.using('primary').create(name=\"User\")\n    await AnalyticsEvent.objects.using('analytics').create(event=\"page_view\")\n\n# Complex queries with advanced features\nusers = await User.filter(\n    age__gte=18,\n    email__icontains=\"@gmail.com\"\n).exclude(\n    is_active=False\n).order_by('-created_at').limit(10)\n\n# Advanced field types\nclass Post(Model):\n    id = IntegerField(primary_key=True)\n    title = CharField(max_length=200)\n    tags = ArrayField(element_type=\"text\")  # PostgreSQL array\n    metadata = JSONBField()  # PostgreSQL JSONB\n    location = GeometryField()  # PostgreSQL geometry\n    file = FileField(upload_to=\"uploads/\")  # File handling\n    image = ImageField(upload_to=\"images/\")  # Image processing\n\n# Window functions and CTEs\nfrom oxen.expressions import WindowFunction, CommonTableExpression\n\n# Window function\nranked_users = await User.annotate(\n    rank=WindowFunction(\"ROW_NUMBER()\", order_by=[\"created_at DESC\"])\n).filter(rank__lte=10)\n\n# Common Table Expression\ncte = CommonTableExpression(\"user_stats\", User.aggregate(total=Count('id')))\n```\n\n### Production Features\n\n```python\n# CLI Database Management\n# oxen db init --url postgresql://user:pass@localhost/mydb\n# oxen db status --url postgresql://user:pass@localhost/mydb\n\n# Migration Management\n# oxen migrate makemigrations --url postgresql://user:pass@localhost/mydb\n# oxen migrate migrate --url
