Model Codeigniter Access Error

Question

I already checked and all my calls are correct. The code ran on Windows and transferred it to Ubuntu. After the transfer gives this error:

An Error Was Encountered

Unable to locate the model you have specified: crudmodel

The model in question (crudModel.php):

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class CrudModel extends CI_Model {

    public function __construct()
    {       
        parent::__construct();
    }

    public function add($tabela= NULL, $dados= NULL){
        if ($this->db->insert($tabela, $dados)){
            return TRUE;
        }
        else{
            return FALSE;
        }
    }

    public function delete($tabela= NULL, $dados= NULL){
        $this->db->where('id', $dados);
        if ($this->db->delete($tabela)){
            return TRUE;
        }
        else return FALSE;    
    }

    public function read($tabela= NULL){
        
        $result= $this->db->get($tabela);
        return $result;        
    }

    public function buscaDados($tabela= NULL, $dados= NULL){

        if ($tabela!= NULL && $dados!= NULL){
            $this->db->where('id', $dados);
            if ($this->db->update($tabela)){
                return TRUE;
            }
            else return FALSE;    
        }
        else return FALSE;    
    }

    public function update($tabela= NULL, $dados= NULL){

        if ($tabela!= NULL && $dados!= NULL){
            return $result= $this->db->get_where($tabela, $dados);
        }
        else return FALSE;        
    }
}

From what I’ve seen, the problem is the autoload... but I don’t know how to hit it.

Autoload:

$autoload['packages'] = array();
$autoload['libraries'] = array('form_validation', 'session', 'database', 'table', );
$autoload['helper'] = array('url', 'form', 'html', 'file', );
$autoload['model'] = array('crudModel', 'sessionModel', );

Call example of model class method:

$dados= $this->crudModel->buscaDados('usuario',$dados);

Answer 1

Just like you already had that problem. I decided to pass the file name to lowercase. I use the first letter of the class name in uppercase, but this does not interfere with class loading.

Example:

File name: usuario_model;

Class name: Usuario_model;

This is related to the fact that the Codeigniter class Ci_loader passes the name of the class to be loaded to lowercase before loading. So, when trying to load a model you can both declare:

$this->load->model('usuario_model'); 

Or

$this->load->model('Usuario_model');

Since the file name in which the class is in lowercase you should have no problem.

But the use of the class strictly follows the syntax used to load it. Example:

Use:

$this->load->model('Usuario_model');

When using it you must use it:

$this->Usuario_model->get_by_id($id);

Use:

$this->load->model('usuario_model');

When using it you must use it:

$this->usuario_model->get_by_id($id);

According to this topical, just leave the file in lowercase

Thefuzzy0ne:

If Nothing has changed then only Difference will be the Operating system (one Linux and one Windows). Windows is case insensitive, whereas Linux is not, so you need to ensure that the filenames for your models are ALL lowercase, and that the class name is defined in all lowercase (as it is with the file), but has the first Letter capitalised. Hopefully this will resolve the problem.

If nothing has changed, then only difference will be the operating system (a Linux and a Windows). Windows is case insensitive, while Linux is not, so it is necessary to make sure that filenames for their models have lowercase letters, and that the name of the class is defined in all lower case letters (as with file), but it has the first uppercase letter. Hopefully this will solve the problem.
