BadMethodCallException Call to undefined method App\Models\UserModel::escapeString

This error after clicking 'Biodata' menu. I don't know if the issue lies with the if Call to undefined method App\Models\UserModel::escapeString. This error appears when im typing code $id = $userModel->escapeString(esc($this->request->uri->getSegment(4)));

My Controller

Code:

public function change_profile()
    {
       
        helper(['form', 'url']);
        $userModel = new UserModel();

        $id = $userModel->escapeString(esc($this->request->uri->getSegment(4)));

        if ($this->request->getMethod() == 'post') {
            $rules = [
                'nama'      => 'required|alpha_space|min_length[2]',

            ];

            if ($this->validate($rules)) {
                $params = [
                    'nama'      => $userModel->escapeString(esc($this->request->getPost('nama'))),

                ];

                $update = $userModel->update($id, $params);

                if ($update) {
                    session()->setFlashdata('success', 'Berhasil edit data');
                    return redirect()->route('admin/user/change_profile');
                } else {
                    session()->setFlashdata('danger', 'Gagal edit data');
                    return redirect()->route('admin/user/change_profile')->withInput();
                }
            } else {
                $data['validation'] = $this->validator;
            }
        }

        $data['title'] = 'Dokumen';
        $data['user'] = $userModel->find($id);

        return view('admin/users/profile', $data);
    }

My View 

Code:

<div class="container">
            <div class="card">
                <div class="card-body">
                    <form action="<?= base_url('admin/user/change_profile') ?>" method="POST" enctype="multipart/form-data">
                        <?= csrf_field(); ?>

                        <div class="form-group">
                          <label for="nama">Nama</label>
                          <input type="text" class="form-control" name="nama" id="nama" value="<?= $user['nama'] ?>" >
                        </div>
       
                         <input type="submit" value="Update" class="btn btn-info"/>
                    </form>
                </div>
            </div>
        </div>

im using Codeigniter 4. Whats wrong with my code

The Model has no escapeString unless you created a method for it in which case you did
not show the escapeString method.

So without seeing the method we can not help you.

What did you Try? What did you Get? What did you Expect?

This is my model

Code:

<?php

namespace App\Models;

use CodeIgniter\Model;
use CodeIgniter\HTTP\RequestInterface;
use Config\Services;

class UserModel extends Model
{
    protected $table      = 'users';
    protected $primaryKey = 'id_user';
    protected $allowedFields = ['nama', 'email', 'password', 'id_level', 'tempat_lahir', 'nip', 'alamat', 'telp', 'avatar1', 'avatar2','avatar3','avatar4','avatar5','avatar6', 'avatar7', 'avatar8', 'avatar9', 'avatar10', 'avatar11', 'avatar12', 'avatar13', 'avatar14', 'avatar15', 'avatar16', 'avatar17', 'avatar18', 'avatar19', 'jk', 'lulusan', 'tanggal_lahir', 'jurusan', 'prodi', 'pt', 'pengalaman', 'pangkat'];
    protected $useTimestamps = true;


    // datatables config
    protected $column_order = array(0, 1, 2, 3, 4, 5);
    protected $column_search = array('nama', 'email');
    protected $order = array('created_at' => 'desc');
    protected $request;

    function __construct(RequestInterface $request = null)
    {
        parent::__construct();
        $this->request = $request;
    }

    public function _get_datatables_query()
    {
        $request = Services::request();
        $i = 0;
        foreach ($this->column_search as $item) {
            if ($request->getPost('search')['value']) {
                if ($i === 0) {
                    $this->groupStart();
                    $this->like($item, $request->getPost('search')['value']);
                } else {
                    $this->orLike($item, $request->getPost('search')['value']);
                }
                if (count($this->column_search) - 1 == $i)
                    $this->groupEnd();
            }
            $i++;
        }

        if ($request->getPost('order')) {
            $this->orderBy($this->column_order[$request->getPost('order')['0']['column']], $request->getPost('order')['0']['dir']);
        } else if (isset($this->order)) {
            $order = $this->order;
            $this->orderBy(key($order), $order[key($order)]);
        }
    }

    public function get_datatables()
    {
        $request = Services::request();
        $this->_get_datatables_query();
        if ($request->getPost('length') != -1)
            $this->limit($request->getPost('length'), $request->getPost('start'));
        $query = $this->get();
        return $query->getResult();
    }

    public function count_filtered()
    {
        $this->_get_datatables_query();
        return $this->countAllResults();
    }

    public function count_all()
    {
        $tbl_storage = $this->db->table($this->table);
        return $tbl_storage->countAllResults();
    }

}

Also looking at your model there is no escapeString method it it either that's why your getting an error.

What did you Try? What did you Get? What did you Expect?
