### 2. Generate structured data

<details>
<summary><strong>🐍 Click to view Python code</strong></summary>

```python
from syda import SyntheticDataGenerator, ModelConfig
from dotenv import load_dotenv
import os

# Load environment variables from .env file
load_dotenv()

# Configure your AI model  
config = ModelConfig(
    provider="anthropic",
    model_name="claude-3-5-haiku-20241022"
)

# Create generator
generator = SyntheticDataGenerator(model_config=config)

# Define your schemas (structured data only)
schemas = {
    "categories": "category_schema.yml",
    "products": "product_schema.yml"
}

# Generate synthetic data with relationships intact
results = generator.generate_for_schemas(
    schemas=schemas,
    sample_sizes={"categories": 5, "products": 20},
    output_dir="output",
    prompts = {
        "Category": "Generate retail product categories with hierarchical structure.",
        "Product": "Generate retail products with names, SKUs, prices, and descriptions. Ensure a good variety of prices and categories."
    }
)

# Perfect referential integrity guaranteed! 🎯
print("✅ Generated realistic data with perfect foreign key relationships!")
```

</details>

**Output:**
```bash
📂 output/
├── 📊 categories.csv    # 5 product categories with hierarchical structure
└── 📊 products.csv      # 20 products, all with valid category_id references
```

### 3. Want to generate documents too? Add document templates!

To generate **AI-powered documents** along with your structured data, simply add the product catalog schema and update your code:

<details>

### 4. Need custom business logic? Add custom generators!

For advanced scenarios requiring **custom calculations** or **complex business rules**, you can add custom generator functions:

<details>
<summary><strong>🔧 Click to view custom generators example</strong></summary>

```python
# Define custom generator functions
def calculate_tax(row, parent_dfs=None, **kwargs):

> 🎯 **Custom generators let you:**
> - **Calculate fields** based on other data (taxes, totals, discounts)
> - **Access related data** from other tables via `parent_dfs`
> - **Implement complex business rules** (pricing logic, inventory rules)
> - **Generate structured data** (arrays, nested objects, JSON)

## 🏗️ Works with Your Existing SQLAlchemy Models

Already using **SQLAlchemy**? Syda works directly with your existing models - no schema conversion needed!

<details>
<summary><strong>🏗️ Click to view SQLAlchemy example</strong></summary>

```python
from sqlalchemy import Column, Integer, String, Float, ForeignKey, Boolean
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import relationship
from syda import SyntheticDataGenerator, ModelConfig
from dotenv import load_dotenv

load_dotenv()

Base = declarative_base()

# Your existing SQLAlchemy models
class Customer(Base):
    __tablename__ = 'customers'
    
    id = Column(Integer, primary_key=True)
    name = Column(String(100), nullable=False, comment='Customer organization name')
    industry = Column(String(50), comment='Industry sector')
    annual_revenue = Column(Float, comment='Annual revenue in USD')
    status = Column(String(20), comment='Active, Inactive, or Prospect')
    
    # Relationships work perfectly
    contacts = relationship("Contact", back_populates="customer")

class Contact(Base):
    __tablename__ = 'contacts'
    
    id = Column(Integer, primary_key=True)
    customer_id = Column(Integer, ForeignKey('customers.id'), nullable=False)
    first_name = Column(String(50), nullable=False)
    last_name = Column(String(50), nullable=False)
    email = Column(String(100), nullable=False, unique=True)
    position = Column(String(100), comment='Job title')
    is_primary = Column(Boolean, comment='Primary contact for customer')
    
    customer = relationship("Customer", back_populates="contacts")

# Generate data directly from your models
config = ModelConfig(provider="anthropic", model_name="claude-3-5-haiku-20241022")
generator = SyntheticDataGenerator(model_config=config)

results = generator.generate_for_sqlalchemy_models(
    sqlalchemy_models=[Customer, Contact],
    sample_sizes={"Customer": 10, "Contact": 25},
    output_dir="crm_data"
)

print("✅ Generated CRM data with perfect foreign key relationships!")
```

</details>

**Output:**
```bash
📂 crm_data/
├── 📊 customers.csv     # 10 companies with realistic industry data
└── 📊 contacts.csv      # 25 contacts, all with valid customer_id references
```

> 🎯 **Zero Configuration**: Your SQLAlchemy `comments` become AI generation hints, `ForeignKey` relationships are automatically maintained, and `nullable=False` constraints are respected!
