Hasmany with child of child in laravel 5.5 - laravel

Question

I have 3 tables.
shops
shop_foods
foods
I need to fetch foods table data when I create hasmany relation with shops_food and store.
$this->hasMany('App\Diet\ShopFood', 'shop_id', 'id');

Answer 1

Please, show your code so we can know what are you trying to do.
But what I can see here is that you have a wrong relationship.
Why are you assigning hasMany in a Many to Many relationship?
In your Shop Model you can make a foods relationship with:
$this->belongsToMany('App\Diet\Food);
Then you can retreive you food when calling
$shop->foods
And the shop_foods with the Pivot property

Answer 2

If i understand correctly you want to get foods when you call shops->shop_foods. if is that
//first you call your shops as you want.
Shop::with(['shops_food' => function($query){
//the 'shops_food' relationship should be called within an array
//this way you could query the relationship as the eloquent model.
//that way you could call the 'foods' relationship inside the shops_food relationship.
$query->with('foods')
}])
...
Note that you must have the relationship declared in shop and shop_foods models
lets your models are like these
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Shop extends Model
{
//
public function shops_food()
{
//shop_id is the foreing key inside your shop_foods table
return $this->hasMany('App\ShopFood','shop_id');
}
....
}
then ShopFood Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class ShopFood extends Model
{
//
public function foods()
{
//shop_food_id is the foreing key inside your foods table
return $this->hasMany('App\Food','shop_food_id');
}
....
}

Answer 3

This reads as if you want
public function foods() {
$this->hasMany('App\Diet\Food');
}
in your ShopFood model and in your Shop model
public function shopfoods() {
$this->hasMany('App\Diet\ShopFood')->with('foods');
}
You can also make 2 separate relations in the Shop model:
public function shopfoods() {
$this->hasMany('App\Diet\ShopFood');
}
public function shopfoodsWithFoods() {
$this->hasMany('App\Diet\ShopFood')->with('foods');
}
So that way you can use whatever you need at that moment.
But the whole thing is really not clear...
I am not even sure how the 3 table are connected, so the hasMany are just guesses.
Nevertheless you can just go with the "with" function.
PS
There is also the possibility to just declare
protected $with = ['foods'];
in your ShopFood model, if you ALWAYS want those 2 connected. It's all in the documentation.
