I have an issue with assign user to any Shop. i created Shop A and Shop B and want to assign user to each shop. Its work fine, when im assign any user to Shop A. however, when i try assign user to Shop B , user alway got in to Shop A not Shop B.
// My User Model

}
// My Shop Model
public function user()
{
return $this->hasMany(\App\User::class, 'user_id');
}
// My UserController
public function index()

$users = User::all();
$shops = Shop::all();
// return view('user', compact('users', 'shops'));
return UserResource::collection($users);
}
public function create(Request $request)
{
$request->validate([
'name' => 'required',
'email' => 'required',
'password' => 'required',
]);
$user = new user();
$user->user_id = auth()->user()->id;
$user->name = $request->name;
$user->email = $request->email;
$user->password = bcrypt($request->password);
$user->save();
return new UserResource($user);
}
// My User.blade.php Code
#extends('layouts.app')
#section('content')
<div class="container" style="width: 50%">
<h2>Create User</h2>
#if ($errors->any())
<div class="alert alert-danger">

Am i doing something wrong with Relationship?

Answer 1

You have two distinct relation from the Shop model to the User model.
// Shop Model
public function users()
{
return $this->hasMany(\App\User::class);
}
public function owner()
{
return $this->belongTo(\App\User::class);
}
If in your controller you want to assign the shop to the user created
public function create(Request $request)
{
$request->validate([
'name' => 'required',
'email' => 'required',
'password' => 'required',
]);
$user = new user();
$user->user_id = auth()->user()->id;
$user->shop_id = $request->shops;
$user->name = $request->name;
$user->email = $request->email;
$user->password = bcrypt($request->password);
$user->save();
return new UserResource($user);
}
For the User Model, you need to define the two different relation with Shop Model
public function shop()
{
return $this->belongsTo(\App\Shop::class); //remove the foreign key or change it to 'shop_id'
}
public function ownedShops()
{
return $this->hasMany(\App\Shop::class);
}
