Access pivotParent in Laravel - laravel

Question

I have 3 tables :
langs : id (PK) , langname
lang_sector : lang_id (FK) , sector_id (FK) , sectorname ....
sectors : id (PK)
Here are the relations in Lang model
public function sectors(){
return $this->belongsToMany('App\Sector')
->withPivot('sectname','sectshortname','sectdescription','sectshortdescription')
->whereNull('lang_sector.deleted_at')
->withTimestamps();
}
Here are the relations in Sector model
public function langs(){
return $this->belongsToMany('App\Lang')
->withPivot('sectname','sectshortname','sectdescription','sectshortdescription')
->whereNull('lang_sector.deleted_at')
->withTimestamps();
}
I create an index method
public function index() {
$countLang = Lang::count();
$countSector = Sector::count();
$admins = Admin::all();
for ($i=1; $i<=$countLang; $i++) {
$langs = Lang::find($i);
$sectors[$i] = $langs->sectors()->get();
}
return view('admin.sectors.index', compact('admins', 'sectors', 'langs', 'countLang', 'countSector'));
}
In my front I have to reach for each sector, the langname which is in the lang table ... When I use the dd() method in the view
#foreach ($sectors as $sector)
#for($i=0; $i < $countSector; $i++)
{{ dd($sector[$i]->pivot) }}
#endfor
#endforeach
I obtain those result (abstract) :
Pivot {#684 ▼
+pivotParent: Lang {#636 ▼
#table: "langs"
#fillable: array:2 [▼
0 => "langname"
1 => "langisocode"
]
....
#attributes: array:6 [▼
"id" => 1
"langname" => "Français"
"langisocode" => "fr-FR"
"created_at" => "2018-02-06 08:19:24"
"updated_at" => "2018-02-07 18:56:21"
"deleted_at" => null
...
]
#original: array:6 [▼
"id" => 1
"langname" => "Français"
...
]
....
}
#foreignKey: "lang_id"
#relatedKey: "sector_id"
#table: "lang_sector"
#primaryKey: "id"
....
#attributes: array:8 [▼
"lang_id" => 1
"sector_id" => 1
"sectname" => "Technologies de l'information et de la Communication"
"sectshortname" => "TIC"
"sectdescription" => "description TIC"
"sectshortdescription" => "description TIC courte"
"created_at" => "2018-02-07 21:41:10"
"updated_at" => "2018-02-07 21:41:10"
]
....
}
It means that i can surelly reach the langs table and its columns... The question is "how can i do it" ...
Thanks for your answer

Answer 1

I see a logic problem
When the ids are continuously, it will work well
+-----+------------+
| id | langname |
| 1 | esp |
| 2 | esp2 |
| 3 | esp3 |
+-----+------------+
$ countLang = Lang :: count (); //3
The for route from 1 to 3
for ($i=1; $i<=$countLang; $i++) {
$langs = Lang::find($i);
$sectors[$i] = $langs->sectors()->get();
}
Here is the error, look at the id's
$countLang = Lang :: count (); //3
+-----+------------+
| id | langname |
| 1 | esp |
| 3 | esp2 |
| 4 | esp3 |
+-----+------------+
The for will never arrive at id = 4, because in the Lang::count(); is 3
Lang :: find (1) ok
Lang :: find (2) error
Lang :: find (3) ok

Answer 2

You could use
$sector->pivot->fieldName;

Answer 3

Finally i rewrote my sql request ... What i want to diplay is the result of this request :
SELECT
sectors.*,
lang_sector.*,
langs.*
FROM sectors
INNER JOIN lang_sector ON sectors.id = lang_sector.sector_id
INNER JOIN langs ON lang_sector.lang_id = langs.id;
So i decided to use query builder :
$sectors = DB::table('sectors')
->join('lang_sector','sectors.id','=','lang_sector.sector_id')
->join('langs','lang_sector.lang_id','=','langs.id')
->select('langs.*', 'lang_sector.*', 'sectors.*')
->get();
Then in my view i don't have to use any pivot stuff
and just have to write this way :
#foreach($sectors as $sector)
{{ $sector->anyfieldfromrequest }}
#endforeach
Thanks for your answers... Mainly Samuel Loza who shows me the problems encountered by my first request
