GroupBy nested multiple levels in Laravel - laravel

Question

I have a list of nested multi level objects.
This is from eloquent query with relationship.
A Place has many Orders
An Order has many Details and one Customer
A Detail has one product and one deliver Period
[
{
"place_id": 1,
"name": "A Building",
"address": "A Street, A Ward, A City",
"orders": [
{
"customer": {
"id": 1,
"name": "Peter",
"phone": "011111111"
},
"order_details": [
{
"period_id": 1,
"period": {
"id": 1,
"start_time": "08:00:00",
"end_time": "08:30:00"
},
"product_id": 1,
"product": {
"name": "A Cup of Tea"
}
}
]
},
{
"customer": {
"id": 2,
"name": "Mary",
"phone": "022222222222"
},
"order_details": [
{
"period_id": 1,
"period": {
"id": 1,
"start_time": "08:00:00",
"end_time": "08:30:00"
},
"product_id": 3,
"product": {
"name": "Glass of Milk Shake"
}
}
]
}
]
},
{
"place_id": 2,
"name": "B Building",
"address": "B Street, B Ward, B City",
"orders": [
{
"customer": {
"id": 3,
"name": "Catherine",
"phone": "0333333333"
},
"order_details": [
{
"period_id": 1,
"period": {
"id": 1,
"start_time": "08:00:00",
"end_time": "08:30:00"
},
"product_id": 2,
"product": {
"name": "A Cup of Coffee"
}
}
]
},
{
"customer": {
"id": 4,
"name": "Tom",
"phone": "04444444444444"
},
"order_details": [
{
"period_id": 2,
"period": {
"id": 1,
"start_time": "10:00:00",
"end_time": "10:30:00"
},
"product_id": 1,
"product": {
"name": "A Cup of Tea"
}
}
]
}
]
}
]
I need group this list by "period" then "place"
Expect result:
[
{
"id": 1,
"start_time": "08:00:00",
"end_time": "08:30:00",
"places": [
{
"place_id": 1,
"name": "A Building",
"address": "A Street, A Ward, A City",
"orders": [
{
"customer": {
"id": 1,
"name": "Peter",
"phone": "011111111"
},
"order_details": [
{
"period_id": 1,
"period": {
"id": 1,
"start_time": "08:00:00",
"end_time": "08:30:00"
},
"product_id": 1,
"product": {
"name": "A Cup of Tea"
}
}
]
},
{
"customer": {
"id": 2,
"name": "Mary",
"phone": "022222222222"
},
"order_details": [
{
"period_id": 1,
"period": {

"end_time": "08:30:00"
},
"product_id": 3,
"product": {
"name": "Glass of Milk Shake"
}
}
]
}
]
},
{
"place_id": 2,
"name": "B Building",
"address": "B Street, B Ward, B City",
"orders": [
{

"end_time": "08:30:00"
},
"product_id": 2,
"product": {
"name": "A Cup of Coffee"
}
}
]
}
]
}
]
},
{
"id": 2,
"start_time": "10:00:00",
"end_time": "10:30:00",
"places": [
{
"place_id": 2,

},
"product_id": 1,

}

}
]
}
]
}

Here is my detail code :
class Place extends Model
{
public function orderDetails()
{
return $this->hasManyThrough(OrderDetail::class,
Order::class,'place_id','order_id','id','id');
}
}
class Period extends Model
{
public function details()
{
return $this->hasMany(OrderDetail::class, 'period_id', 'id');
}
}
class Order extends Model
{
public function place()
{
return $this->belongsTo(Place::class, 'place_id', 'id');
}
public function user()
{
return $this->belongsTo(User::class, 'user_id', 'id');
}
public function details()
{
return $this->hasMany(OrderDetail::class, 'order_id', 'id');
}
}
class OrderDetail extends Model
{
public function period()
{
return $this->belongsTo(Period::class, 'period_id', 'id');
}
public function product()
{
return $this->belongsTo(Product::class, 'product_id', 'id');
}
public function order()
{
return $this->belongsTo(Order::class, 'order_id', 'id');
}
}
Place::with(['orderDetails', 'orderDetails.product', 'orderDetails.period', 'orderDetails.order.user'])->get()->toArray();
I m using laravel so better use collection helper of laravel to solve this faster.
Please help me . Thanks
Updated:
i used another query and group
In OrderDetail model add:
protected $appends = ['place_id'];
public function getPlaceIdAttribute()
{
return $this->order->place_id;
}
Then use this query i can group period than place but it 's only contain id.
OrderDetail::with(['order','order.user','order.place','product','period'])->get()->groupBy(['period_id','place_id'])->toArray();

Answer 1

I solved this .
OrderDetail::with(['order','order.user','order.place','product','period'])->get()->groupBy(['period.id','order.place.id'])->map(function ($periods) {
$period = $periods->first()->first()->period;
return [
"start_time" => $period->start_time,
"end_time" => $period->end_time,
"places" => $periods->map(function ($places) {
$place = $places->first()->place;
return [
"name" => $place->name,
"address" => $place->address,
"details" => $places->toArray()
];
})->toArray()
];
})->toArray();
