错误：（application\models/projects/It_project_companies.php存在，但没有声明类It_project_companies），当我试图保存一个项目时发生。我正在从控制器加载保存方法中的模型：

public function addProject()
{
    $input = $this->input->post(null, true);

    if ($this->validateFields($input)) {
        $this->load->model('projects/it_projects_notifiers');
        $this->load->model('projects/it_project_companies'); //my model

        $projectData = [
            'title' => $input['project_subject'],
            'description' => $input['project_details'],
            'creator' => $_SESSION['UserID'],
            'affected' => $input['affected_id'],
            'assignee' => $input['project_responsible'],
            'priority' => $input['project_priority'],
            'type' => $input['project_type'],
            'created' => date('Y-m-d H:i:s'),
            'company' => $input['project_companies'],//$project_company,
            'start_date' => date('Y-m-d', strtotime($input['project_start_date'])),
            'end_date' => date('Y-m-d', strtotime($input['project_end_date'])),
            'estimated' => ($input['project_estimated_days'] * 24 + $input['project_estimated_hours']),
        ];

        if ($this->db->insert('it_projects', $projectData)) {
            $projectID = $this->db->insert_id();

            $this->it_project_companies->addCompanies($projectID, $input['project_companies']);

            $this->it_projects_notifiers->add_notifiers_affected($projectID, $input['affected_id']);

            $this->it_projects_notifiers->add_notifiers($projectID, $input['project_notifiers']);

            // add files ...
            $this->uploadFiles($_FILES, $projectID);

            $this->load->model('projects/it_projects_notifications');
            $this->it_projects_notifications->send_notifications('new_project', 0, $projectID, $_FILES);
        }
    }
}

和addCompanies方法：

class It_project_companies extends \My_Model
{
    public function __construct()
    {
        parent::__construct();
    }

    public function addCompanies($projectID, $companyIDs) {
        foreach ($companyIDs as $companyID) {
            $projectCompanyData = [
                'project_id' => $projectID,
                'company_id' => $companyID,
            ];
            $this->db->insert('it_project_companies', $projectCompanyData);
        }
    }
}

我必须补充的是，目前我没有查询连接所需的表等...因为我不知道如何使他们和错误仍然发生时，我有查询，可能写错了...

我的解决方案是删除名称空间，因为composer.json中没有自动加载，我不知道使用$this->load->model()加载模型是否是一种好方法，或者我应该使用Composer自动加载类。

## Your model should look like this ##

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

class It_project_companies extends CI_Model
{
    public function addCompanies($projectID, $companyIDs){}
}

## but since you are extending ##
<?php
    defined('BASEPATH') or exit('No direct script access allowed');

    class It_project_companies extends My_Model
    {
        public function addCompanies($projectID, $companyIDs){}
    }

我不知道为什么My_Model前面有一个“/”

## My_Model ##
<?php
defined('BASEPATH') or exit('No direct script access allowed');

class MY_Model extends CI_Model
{
 public function __construct(){}
}
