Eloquent macros for querying the latest HasMany relationship in Laravel.
More information on the problem and solutions: [Dynamic scope on latest record in Laravel's HasMany relationships, Part 1: solving with Subqueries - nullthoughts.com](https://nullthoughts.com/development/2019/10/08/dynamic-scope-on-latest-relationship-in-laravel/)
## Installation
Install via composer:
`composer require nullthoughts/laravel-latest-relation`
## Usage / Examples
Use the Builder methods inside a whereHas closure:
### Latest:
#### whereLatestRelation($relation, $column, $operator = null, $value = null)
**Query**
```php
$users = User::whereLatestRelation('logins', 'device_type', '=', 'desktop');
```
**Dynamic Scope**
```php
public function scopeUsingDevice($query, $device)
{
return $query->whereLatestRelation('logins', 'device_type', $device);
}
public function scopeHavingCountry($query)
{
return $query->whereLatestRelation('logins', 'country', '!=', 'null');
}
```
#### whereLatest($column, $value)
**Query**
```php
$users = User::whereHas('logins', function ($query) {
$query->whereLatest('device_type', 'desktop');
});
```
**Dynamic Scope**
```php
public function scopeUsingDevice($query, $device)
{
return $query->whereHas('logins', function ($query) use ($device) {
$query->whereLatest('device_type', $device);
});
}
```
#### latestRelation()
**Query**
```php
$users = User::whereHas('logins', function ($query) {
$query->latestRelation()->whereBetween(
'created_at', [
Carbon::now()->startOfDay(),
Carbon::now()->endOfDay()
]);
});
```
**Dynamic Scope**
```php
public function scopeHavingDeviceType($query)
{
return $query->whereHas('logins', function ($query) {
$query->latestRelation()->whereNotNull('device_type');
});
}
```
### Earliest:
```php
$users = User::whereLatestRelation('logins', 'device_type', 'desktop');
$users = User::whereHas('logins', function ($query) {
$query->whereEarliest('device_type', 'desktop');
});
$users = User::whereHas('logins', function ($query) {
$query->earliestRelation()->whereNotNull('device_type');
});
```
