Solve the problem that Laravel cannot detect the "username" input

Question

I am new to laravel and my code worked before but I changed "name" to "username" and then if I click submit it says it has no default value.

class UserSignup extends Controller {
    public function register(Request $request) {

        $validatedData = $request->validate([
            'username' => ['required', 'string','max:255', Rule::unique('users')],
            'email' => ['required', 'email', 'max:255', Rule::unique('users')],
            'password' => 'required|min:8'
        ]);

        $validatedData['password'] = bcrypt($validatedData['password']);

        $user = User::create($validatedData);

return response()->json(['message' => 'User created successfully!', 'user' => $user]);
    }
}

I tried changing "name" to "username" as shown below

$validatedData = $request->validate([
            'username' => ['required', 'string','max:255', Rule::unique('users')],
            'email' => ['required', 'email', 'max:255', Rule::unique('users')],
            'password' => 'required|min:8'
        ]);

After clicking submit, an error appears saying it has no default value.

I just want to put 'username' into the database.

Answer 1

I just added the username in app.php and then it worked

protected $fillable = [
        'username',
        'name',
        'email',
        'password',
    ];

Answer 2

You can set the name value to non-empty in the database (and migrations). If you also want to have the name and username attributes, there are two options:

1. Set a default value for the name attribute (or make it nullable) and add the username attribute using migrations in the database.

2. Create a name field in the registration form and request validation, now you can add it to the database record.

Tip: In your model file (User.php) you must add each property you want to fill to the $fillable attribute:

protected $fillable = ['name', 'username', ...];
