Lumen/Laravel Eloquent hasManyThrough nested results - php

Question

I`m trying to achieve a nested result using Laravel Eloquent.
My logic:
Cities, Neighbourhoods, Blocks
A city has many neighbourhoods
A neighbourhood has many blocks
The result that I want to acomplish:
City
Neighbourhoods
Blocks
The data shoud be:
[
{
id: 1,
name: "New York",
neighbourhoods: [
{
id: 1,
name: "Neighbourhood 1",
city_id: 1,
blocks: [
{
id: 1,
name: "Neighbourhood 1 Block 1",
neighbourhood_id: 1
},
{
id: 2,
name: "Neighbourhood 1 Block 2",
neighbourhood_id: 1
}
]
},
{
id: 2,
name: "Neighbourhood 2",
city_id: 1,
blocks: [
{
id: 3,
name: "Neighbourhood 2 Block 1",
neighbourhood_id: 2
},
{
id: 4,
name: "Neighbourhood 2 Block 2",
neighbourhood_id: 2
}
]
}
]
}
]
Models:
City.php
public function neighbourhood()
{
return $this->hasMany('App\Neighbourhood');
}
public function block()
{
return $this->hasManyThrough('App\Block', 'App\Neighbourhood', 'city_id', 'neighbourhood_id', 'id');
}
Neighbourhood.php
public function city()
{
return $this->belongsTo('App\City');
}
public function block()
{
return $this->hasMany('App\Block');
}
Block.php
public function neighbourhood()
{
return $this->belongsTo('App\Neighbourhood');
}
The actual result gives me this:
[
{
"id": 1,
"name": "Ney York",
"neighbourhoods": [
{
"id": 1,
"city_id": 1,
"name": "Heighbourhood 1"
},
{
"id": 2,
"city_id": 1,
"name": "Heighbourhood 2"
},
{
"id": 4,
"city_id": 1,
"name": "Păcurari"
}
],
"blocks": [
{
"id": 1,
"name": "Heighbourhood 1 Block 1",
"neighbourhood_id": 1,
"city_id": 1
},
{
"id": 2,
"name": "Heighbourhood 1 Block 2",
"neighbourhood_id": 1,
"city_id": 1
}
]
}
]
I want to get the results nested. Is there a way to do this? I`m missing something?
Of course that it can me done with PHP foreach loop but this will be manual job. I wonder if I can get the results this way directly from the query.
Thank you.
SOLUTION:
$result = City::with('neighbourhoods.blocks')->get();

Answer 1

This should do:
$result = City::with('neighbourhoods.blocks')->get();
You can do nested relationship queries with dot notation.
