Laravel 5.1 hasMany relation query

Question

I'm trying to develop a simple web-app where I store a farmer's detail and his/her cultivation information.

I have 2 database tables - farmer and farmer_crop .

farmer table
id | name | phone

farmer_crop table
id | farmer_id | farming_location | farming_crop_name | harvest_end_date

I made 2 controllers - FarmerController & FarmerCropController . A Farmer can cultivate many crops so the Farmer has hasMany with FarmerCrop. Now I want to show a list of farmers using the FarmerController 's index method where I get farmers who are farming wheat. How do I go about achieving this?

Answer 1

$farmers = App\Farmer::with(['crops' => function ($query) {
    $query->where('farming_crop_name', '=', 'wheat');
}])->get();

Answer 2

You would use something like.

class = FarmerController extends Controller

public function index()
{
    $results = FarmerCrop::with('farmers')
               ->where('farming_crop_name', 'wheat')
               ->get();

    return view('farms.crops', compact('results'));
}

I don't know the name of your models so best guess above..

Update after comment

In that case you would just add an additional were clause.Ezequiel was alos correct with his answer. But I will modify his and add in your new requirements.

$farmers = App\Farmer::with(['crops' => function ($query) {
    $query->where('farming_crop_name', 'wheat');
}])
->where('user_type_id', 3)
->get();
