Question 

Error dump:

mysqli_sql_exception #1062
Duplicate entry 'john' for key 'users.username'

A part of my code:

Code:
$dataUser = [
'username' => $request->getPost('username'),
'email'    => $request->getPost('email'),
'password' => md5($request->getPost('password'))
];

$userModel = new UserModel();

$userModel->insert($dataUser);

Hope it will help a little bit.

helped, but it would help more if it were possible to do this with an if, I just read in the documentation that the save or insert methods return false when they fail

use validation, for your case: duplicated username entry
use this rules:

'username' => 'required||is_unique[users.username]' // usename already exist in db

or

'username' => 'is_not_unique[users.username]' // username not exist in db


give validation error if username already exist or not

If has any error but you have set validation rule in model
If(! $model-save($data)){
$model->errors;
}

also can use $res = $this->db->error(); echo $res['message'];
in model
