### State
Represents the 36 states of Nigeria plus FCT. Each state belongs to a zone.

### LGA (Local Government Area)

**Note:** Model is ready, but postal code data is not included. You can add your own postal code data.

## Usage Examples

### Using the Models

```python
from django_ng_locations.models import Zone, State, LGA

# Get all zones
zones = Zone.objects.all()

# Get a specific state
lagos = State.objects.get(name="Lagos")

# Get all LGAs in a state
lagos_lgas = LGA.objects.filter(state=lagos)

# Get state's zone
zone = lagos.zone  # Returns "South West"

# Get all states in a zone
south_west_states = State.objects.filter(zone__name="South West")
```

### Using Utility Functions

```python
from django_ng_locations.utils import (
    get_states_by_zone,
    get_lgas_by_state,
    get_state_by_name,
    search_locations
)

# Get all states in a zone
states = get_states_by_zone("North Central")

# Get all LGAs in a state
lgas = get_lgas_by_state("Lagos")

# Get a specific state
lagos = get_state_by_name("Lagos")

# Search across all location types
results = search_locations("Ikeja")
# Returns: {'zones': [...], 'states': [...], 'lgas': [...], 'cities': [...], 'wards': [...]}
```

### In Django Forms

```python
from django import forms
from django_ng_locations.models import State, LGA

class AddressForm(forms.Form):
    state = forms.ModelChoiceField(
        queryset=State.objects.all().order_by('name')
    )
    lga = forms.ModelChoiceField(
        queryset=LGA.objects.all().order_by('name')
    )
    
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        # Filter LGAs based on selected state
        if 'state' in self.data:
            try:
                state_id = int(self.data.get('state'))
                self.fields['lga'].queryset = LGA.objects.filter(
                    state_id=state_id
                ).order_by('name')
            except (ValueError, TypeError):
                pass
```

### In Django REST Framework

```python
from rest_framework import serializers
from django_ng_locations.models import State, LGA

class StateSerializer(serializers.ModelSerializer):
    zone_name = serializers.CharField(source='zone.name', read_only=True)
    lga_count = serializers.SerializerMethodField()
    
    class Meta:
        model = State
        fields = ['id', 'name', 'code', 'capital', 'zone_name', 'lga_count']
    
    def get_lga_count(self, obj):
        return obj.lgas.count()
```
