Laravel pass parameters from controller to Model using 'With' clause - php

Question

I am new in Laravel,
I want to pass the the $id from my controller in the model using with clause
My model
class Menucategory extends Model
{
protected $fillable = ['title', 'parent_id', 'restaurant_id'];
// loads only direct children - 1 level
public function children()
{
return $this->hasMany('App\Menucategory', 'parent_id');
}
// recursive, loads all descendants
public function childrenRecursive()
{
return $this->children()->with('childrenRecursive');
}
}
My Controller
public function show($id)
{
$menucatagories = Menucategory::with('childrenRecursive')->where('restaurant_id',$id)->where('parent_id','0')->get();
return $menucatagories;
}
My current output is
[
{
"id": 1,
"title": "TestMenu Parant",
"parent_id": 0,
"restaurant_id": 12,
"children_recursive": [
{
"id": 2,
"title": "TestMenu SubCat1",
"parent_id": 1,
"restaurant_id": 12,
"children_recursive": [
{
"id": 6,
"title": "TestMenu other sub cat",
"parent_id": 2,
*******************
"restaurant_id": 13,
*******************
"children_recursive": []
},
{
"id": 7,
"title": "TestMenu other sub cat",
"parent_id": 2,
"restaurant_id": 12,
"children_recursive": []
}
]
},
{
"id": 3,
"title": "TestMenu SubCat2",
"parent_id": 1,
"restaurant_id": 12,
"children_recursive": []
}
]
}
]
I passed $id=12 , but the problem is I get the values of others restaurant_id in my child array, but if i use this it shows the correct jSON
public function childrenRecursive()
{
$id=12;
return $this->children()->with('childrenRecursive')->where('restaurant_id',$id);
}
my questions is how can i pass the $id from the controller to the model or is there any other approach?

Answer 1

You can pass your parameter in the controller itself using the following way.
public function show($id)
{
$menucatagories =Menucategory::with(array('childrenRecursive'=>function($query) use ($id){
$query->select()->where('restaurant_id',$id);
}))
->where('restaurant_id',$id)->where('parent_id','0')->get();
return $menucatagories;
}

Answer 2

Your childrenRecursive isn't wrong at all.
See here an simliar example: https://stackoverflow.com/a/18600698/2160816
So I think this should work
public function childrenRecursive($id = 12){
return $this->children()->where('restaurant_id',$id)->with('childrenRecursive');
}
Your Controller then could call
public function show($id)
{
$menucatagories = Menucategory::where('parent_id','0')->childrenRecursive(12)->get();
return $menucatagories;
}
I could not test it so may it won't work 100%
