Laravel - How to find foreign key value - php

Question

first time working with Laravel and PHP. I am trying to insert row in the table profile where the attribute uID is a foreign key referencing to uID on user table, but getting errors. How do I insert just the summary attribute of the profile and set the uID (foreign key) automatically. I can insert users with uID without any problems. Here are my model and controller files. Thanks!
user model
namespace App;
use Illuminate\Database\Eloquent\Model;
class user extends Model
{
// specify which attributes can be filled out during registration
public $timestamps = false;
protected $fillable=['firstname','lastname','email','password',];
public function profile(){
return $this->hasOne(profile::class);
}
}
profile model
namespace App;
use Illuminate\Database\Eloquent\Model;
class profile extends Model
{
//
public $timestamps = false;
protected $fillable = ['summary',];
public function user(){
return $this->belongsTo(user::class);
}
}
profile migration
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateProfilesTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
// create profile table
Schema::create('profiles', function (Blueprint $table) {
$table->increments('pID');
$table->timestamp('created_at')->useCurrent();
$table->string('summary')->default('');
$table->unsignedInteger('uID');
$table->foreign('uID')->references('uID')->on('users')->onDelete('cascade');
});
}
}
profile controller
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\profile;
class ProfileController extends Controller
{
public function create()
{
//
return view('profile.create');
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
// used to store user profile after validation
$this->validate($request,[
'summary' => 'required'
]);
$profile = new profile([
'summary' => $request->get('summary'),
'uID' => $request->user()->uID
]);
return redirect()->route('profile.create')->with('success','Profile created');
}
}

Answer 1

Welcome to Laravel :)
On your profile Model on the user method you need to define the foreign key.
public function user(){
return $this->belongsTo(user::class, 'uID');
}
If you don't provide the foreign key, it will look for user_id field.

Answer 2

Alright, a couple of things that could need to be sort out:
Declare your Classes with a capitalised letter. It is Profile not profile. Avoid plurals as well. More on that can be explored reading about PSR-x;
You have deviated from the laravel way in regards to foreign keys. Therefore, you need to specify in your relationship which are the keys to connect with:
Also, notice how I changed your method name from user -> users
public function users()
{
return $this->belongsTo(user::class, 'id', 'uID');
}
As well as for your profile relationship:
public function profiles(){
return $this->hasOne(profile::class, 'uID', 'id');
}
