我正在使用框架laravel 5.4，我有3个表（用户，包，联系人）

When i want to code with the relationships(hasMany and belongsTo) I get the error:

QueryException

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'contacts.user_id' in 'where clause' (SQL: select * from contacts where contacts.user_id = 2 and contacts.user_id is not null and contacts.deleted_at is null)

This is the controller, ContactController.php:

 <?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Contact;

use Auth;

use App\Http\Requests\contactRequest;

class ContactController extends Controller
{
    public function __construct()
    {
        $this->middleware('auth');
    }

    public function index()
    {
        $listcontact = Auth::user()->contacts;

        return view('contact.index', ['lists' => $listcontact]);
    }

    public function create()
    {
        return view('contact.create');
    }

            public function store(contactRequest $request)
    {
        $contact = new Contact();

        $contact->nom=$request->input('nom');
        $contact->tel=$request->input('tel');
        $contact->genre=$request->input('genre');
        $contact->age=$request->input('age');
        $contact->ville=$request->input('ville');

        $contact->user_idd=Auth::user()->id;

        $contact->save();

        session()->flash('success', 'Contact bien enregistré!!');

        return redirect('contacts');
    }

    public function edit($id)
    {
        $contact = Contact::find($id);

        return view('contact.edit', ['cont' => $contact]);
    }

    public function update(contactRequest $request, $id)
    {
        $contact = Contact::find($id);

        $contact->nom = $request->input('nom');
        $contact->tel = $request->input('tel');
        $contact->genre = $request->input('genre');
        $contact->age = $request->input('age');
        $contact->ville = $request->input('ville');

        $contact->save();

        session()->flash('edited', 'Contact bien modifié!!');

        return redirect('contacts');
    }

    public function destroy(Request $request, $id)
    {
        $contact = Contact::find($id);

        $contact->delete();

        return redirect('contacts');
    }
}

change to $contact->user_idd=Auth::user()->id;

$contact->user_id=Auth::user()->id;
