|
|
|
|
## Overview
|
|
The Location System provides comprehensive location management for parks, areas, and other entities through polymorphic relationships. It includes geocoding, map integration, and location-based search capabilities.
|
|
|
|
## Components
|
|
|
|
### 1. Database Structure
|
|
|
|
#### Locations Table
|
|
```sql
|
|
CREATE TABLE locations (
|
|
id bigint PRIMARY KEY,
|
|
locatable_type varchar(255),
|
|
locatable_id bigint,
|
|
address varchar(255) NULL,
|
|
city varchar(255),
|
|
state varchar(255) NULL,
|
|
country varchar(255),
|
|
postal_code varchar(255) NULL,
|
|
latitude decimal(10,8),
|
|
longitude decimal(11,8),
|
|
elevation decimal(8,2) NULL,
|
|
timezone varchar(255) NULL,
|
|
metadata json NULL,
|
|
is_approximate boolean DEFAULT false,
|

geocoding_data json NULL,
|
|
geocoded_at timestamp NULL,
|

|
|
'address',
|
|
'city',
|
|
'state',
|
|
'country',
|
|
'postal_code',
|
|
'latitude',
|
|
'longitude',
|
|
'elevation',
|
|
'timezone',
|
|
'metadata',
|
|
'is_approximate',
|
|
'source',
|
|
'geocoding_data',
|
|
'geocoded_at',
|
|
];
|
|
|
|
protected $casts = [
|
|
'latitude' => 'decimal:8',
|
|
'longitude' => 'decimal:8',
|
|
'elevation' => 'decimal:2',
|
|
'metadata' => 'array',
|
|
'geocoding_data' => 'array',
|
|
'geocoded_at' => 'datetime',
|
|
'is_approximate' => 'boolean',
|
|
];
|
|
}
|
|
```
|
|
|
|
### 2. Trait Implementation
|
|
```php
|
|
trait HasLocation
|
|
{
|
|
public function location()
|
|
{
|
|
return $this->morphOne(Location::class, 'locatable');
|
|
}
|
|
|
|
public function getCoordinatesAttribute()
|
|
{
|
|
return [
|
|
'lat' => $this->location?->latitude,
|
|
'lng' => $this->location?->longitude,
|
|
