Codeigniter 4 BadMethodCallException - codeigniter-4

Question

I am trying to do a user login and I am getting this error which I can't figure out why. Also, I am not sure whether I can mentioned 1 more question or do I have to separate it on another topic. If I want user to login using either username or email address, how should I do it?
I have uploaded the error message here
The error seems to be at this line :
$user = $model->model('username', $this->request->getVar('username'))
->first();
Below are my code:
Controller
public function login()
{
$data = [];
helper(['form']);
$validation = \Config\Services::validation();
if($this->request->getMethod() == 'post'){
//validations
$rules = [
'username' => 'required',
'password' => 'required|validateUser[username, password]'
];
$errors = [
'password' => [
'validateUser' => 'Username or Password don\'t match'
]
];
if(!$this->validate($rules, $errors)){
$data['validation'] = $this->validator;
}else{
$model = new AccountModel();
$user = $model->model('username', $this->request->getVar('username'))
->first();
$this->setUserMethod($user);
return redirect()->to('account');
}
}
echo view('templates/header', $data);
echo view('account/login');
echo view('templates/footer');
}
Model
<?php namespace App\Models;
use CodeIgniter\Model;
class AccountModel extends Model{
protected $table = 'users';
protected $allowedFields = [
'username',
'email',
'firstname',
'lastname',
'dob',
'country',
'contact',
'password',
'created_at',
'updated_at',
'created_by'
];
protected $beforeInsert = ['beforeInsert'];
protected $beforeUpdate = ['beforeUpdate'];
protected function beforeInsert(array $data) {
$data = $this->passwordHash($data);
return $data;
}
protected function beforeUpdate(array $data) {
$data = $this->passwordHash($data);
return $data;
}
protected function passwordHash(array $data){
if(isset($data['data']['password']))
$data['data']['password'] = password_hash($data['data']['password'], PASSWORD_DEFAULT);
return $data;
}
}
?>
Hope someone can help me out here. Thanks in advance!

Answer 1

So you have this line trying to call a method called model which does not exist...
This is what you have...
$user = $model->model('username', $this->request->getVar('username'))
->first();
If you have read the CodeIgniter User Guide, you would see that you really want to be using where instead of model... Maybe cause you had model stuck in your head, as that happens sometimes.
$user = $model->where('username', $this->request->getVar('username'))->first();
See how that flies for you.
