Fetch relationship with respective to relationship data in Laravel 5.7 - laravel

Question

Let me give you a basic overview:
There is an app where people will register their pets and would report when a pet is lost. Also, people who have seen a lost pet would report a sighting for the pet so that the owner of the pet would be notified and he could retrieve his pet.
I have five models:-
Color Model
class Color extends Model
{
public function colorPet()
{
return $this->hasMany('App\Models\Pet');
}
}
Breed Model
class Breed extends Model
{
public function breedPetType()
{
return $this->belongsTo('App\Models\PetType', 'pet_type_id');
}
public function breedPet()
{
return $this->hasMany('App\Models\Pet');
}
}
Pet Type Model
class PetType extends Model
{
public function petTypeBreed()
{
return $this->hasMany('App\Models\Breed');
}
}
Pet Model
class Pet extends Model
{
public function petBreed()
{
return $this->belongsTo('App\Models\Breed', 'breed_id');
}
public function petPetType()
{
return $this->belongsTo('App\Models\PetType', 'pet_type_id');
}
public function petColor()
{
return $this->belongsTo('App\Models\Color', 'color_id');
}
public function petUser()
{
return $this->belongsTo('App\User', 'user_id');
}
}
Lost Report
class LostReport extends Model
{
public function lostReportPet()
{
return $this->belongsTo('App\Models\Pet', 'pet_id');
}
public function lostReportUser()
{
return $this->belongsTo('App\User', 'user_id');
}
public function lostReportPetSighting()
{
return $this->hasMany('App\Models\PetSighting', 'lost_report_id');
}
}
Pet Sighting
class PetSighting extends Model
{
public function petSightingLostReport()
{
return $this->belongsTo('App\Models\LostReport', 'lost_report_id');
}
}
Here is ny query:-
$petSightingRadiusQueryString = "( $unitDistance * acos( cos( radians($latitude) ) * cos( radians( pet_sightings.latitude ) )
* cos( radians( pet_sightings.longitude ) - radians($longitude) ) + sin( radians($latitude) ) * sin(radians(pet_sightings.latitude)) ) )";
$lostPetQuery = LostReport::with('lostReportPet')
->where(array(
'lost_reports.is_found' => Globals::SMALL_CHAR_NO))
->whereHas('lostReportPet', function($queryReportPet) {
$queryReportPet->where(array(
'pets.status' => Globals::SMALL_CHAR_ACTIVE,
'pets.is_delete' => Globals::SMALL_CHAR_NO,
'pets.is_lost' => Globals::SMALL_CHAR_YES
));
});
$lostPetQuery = $lostPetQuery->where(function($orQuery) use($userId, $petTypeArrayForLostPet, $lostPetRadiusQueryString, $lostPetRadius, $petSightingRadiusQueryString, $petSightingRadius){
$orQuery->where('lost_reports.user_id', $userId) // where the post report is by owner
->orWhere(function($lostPetNotificationQuery) use($petTypeArrayForLostPet, $lostPetRadiusQueryString, $lostPetRadius){
$lostPetNotificationQuery->whereIn('pets.pet_type_id', $petTypeArrayForLostPet)
->whereRaw($lostPetRadiusQueryString . ' < ' . $lostPetRadius);
}) // where the lost report is of same pet type
->orWhereHas('lostReportPetSighting', function($petSightingNotificationQuery) use ($petSightingRadiusQueryString, $petSightingRadius){
$petSightingNotificationQuery->whereRaw("pet_sightings.id = (SELECT MAX(pet_sightings.id) FROM pet_sightings WHERE pet_sightings.lost_report_id = lost_reports.id) AND " . $petSightingRadiusQueryString . " < " . $petSightingRadius);
}); // where pet sighting is enabled
});
Here is the result I am getting:-
Array
(
[id] => 1
[pet_id] => 3
[user_id] => 2
[phone] => 6290453837
[latitude] => 22.572645
[longitude] => 88.363892
[missing_date] => 2020-03-03 00:00:00
[found_date] =>
[is_found] => n
[is_delete] => n

[modified_date] => 2020-03-03 15:08:03
[created_at] => 2020-03-03 15:08:03
[updated_at] => 2020-03-03 15:08:03
[lost_report_pet] => Array
(

[created_at] => 2020-03-03 15:08:03
[updated_at] => 2020-03-03 15:08:03
)
)
As you can see, the relationship 'lost_report_pet'. How can I get the breed, color and pet_type relationship from lost_report_pet?

Answer 1

I'm pretty sure you could try with the relationship dot notation:
LostReport::with([
'lostReportPet.petBreed',
'lostReportPet.petPetType',
'lostReportPet.petColor'
]);
