Cant persist data to the database? (Laravel) - laravel

Question

I'm new to Laravel. My data doesn't seem to get to the database. Here's my Controller code:
public function store(Request $request)
{
$rules = [
'first_name' => 'required|string|min:3|max:255',
'last_name' => 'required|string|min:3|max:255',
'gender' => 'required|string|min:3|max:255',
'qualifications' => 'required|string|min:3|max:255'
];
$validator = FacadesValidator::make($request->all(), $rules);
if ($validator->fails()) {
return redirect('/home')
->withInput()
->withErrors($validator);
} else{
$data = $request->input();
try {
$crud = new CRUD;
$crud->first_name = $request->get('first_name');
$crud->last_name = $request->get('last_name');
$crud->gender = $request->get('gender');
$crud->qualifications = $request->get('qualifications');
$crud->save();
return redirect('/home')->with('status',"Insert successfully");
} catch (\Throwable $th) {
return redirect('/home')->with('failed',"Insert Failed");
}
}
}
And my Model:
protected $table = '$user';
protected $fillable = [
'first_name', 'last_name', 'gender', 'qualifications'
];
public $timestamps = true;
And my route(Web.php):
Route::post('/store', [App\Http\Controllers\CRUDController::class, 'store'])->name('insert');
Here is my migration for the users table:
Schema::create('user', function(Blueprint $table) {
$table->bigIncrements('id');
$table->string('first_name');
$table->string('last_name');
$table->string('gender');
$table->string('qualifications');
$table->timestamps();
});

You should fix your table name in your model, since your table is called user:
protected $table = "user";
Also, you can use mass assignment to fill your models:
$crud = CRUD::create($request->validated());
It should fix your problem.
