我的Codeigniter模型未加载，我没有错误。 当我尝试使用$ this-＆gt; load-＆gt;模型（'All_sensor_data'）时。什么都没发生。我不知道发生了什么事。我尝试过更改文件名，类名等。
顺便说一句，从未到达该日志消息。我可以删除$ this-＆gt; load-＆gt;模型（'all_sensor_data'），然后日志消息就可以了。
我的基本模型：
<?php
//Filename: application/core/my_model.php
class MY_Model extends CI_Model {
const DB_TABLE = 'abstract';
const DB_TABLE_PK = 'abstract';
/**
* Create record.
*/
private function insert() {
$this->db->insert($this::DB_TABLE, $this);
$this->{$this::DB_TABLE_PK} = $this->db->insert_id();
}
/**
* Update record.
*/
private function update() {
$this->db->update($this::DB_TABLE, $this, $this::DB_TABLE_PK);
}
/**
* Populate from an array or standard class.
* @param mixed $row
*/
public function populate($row) {
foreach ($row as $key => $value) {
$this->$key = $value;
}
}
/**
* Load from the database.
* @param int $id
*/
public function load($id) {
$query = $this->db->get_where($this::DB_TABLE, array(
$this::DB_TABLE_PK => $id,
));
$this->populate($query->row());
}
/**
* Delete the current record.
*/
public function delete() {
$this->db->delete($this::DB_TABLE, array(
$this::DB_TABLE_PK => $this->{$this::DB_TABLE_PK},
));
unset($this->{$this::DB_TABLE_PK});
}
/**
* Save the record.
*/
public function save() {
if (isset($this->{$this::DB_TABLE_PK})) {
$this->update();
}
else {
$this->insert();
}
}
/**
* Get an array of Models with an optional limit, offset.
*
* @param int $limit Optional.
* @param int $offset Optional; if set, requires $limit.
* @return array Models populated by database, keyed by PK.
*/
public function get($limit = 0, $offset = 0) {
if ($limit) {
$query = $this->db->get($this::DB_TABLE, $limit, $offset);
}
else {
$query = $this->db->get($this::DB_TABLE);
}
$ret_val = array();
$class = get_class($this);
foreach ($query->result() as $row) {
$model = new $class;
$model->populate($row);
$ret_val[$row->{$this::DB_TABLE_PK}] = $model;
}
return $ret_val;
}
}
我的模特：
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
//filename: application/models/all_sensor_data.php
class All_sensor_data extends MY_Model {
const DB_TABLE = "all_sensor_data";
const DB_TABLE_PK = 'id';
/**
* All_Sensor_Data primary key
* @var int
*/
public $id;
/**
* Sensor Name
* @var string
*/
public $name;
/**
* Defines the type of sensor. e.g. LIGHT, MOISTURE, TEMPERATURE
* @var string
*/
public $type;
/**
* Date the row was added
* @var
*/
public $modify_date;
/**
* Value read from the sensor
* @var int
*/
public $value;
/**
* Describes the section where the sensor is located.
* @var
*/
public $section;
}
这是我的控制器：
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**
* Created by PhpStorm.
* User: James
* Date: 6/24/14
* Time: 9:25 PM
*/
class Incoming extends CI_Controller
{
function __construct() {
parent::__construct();
$this->load->model('All_sensor_data');
}
public function index() {
echo "Hello, Incoming Controller";
}
public function incomingSensorData($sensor, $value)
{
log_message('info', __CLASS__ . ' ' . __LINE__ . ' ' . 'Hello Incoming Data');
}
}

答案 0 :(得分：1)
你的模型是否正确，即
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class All_sensor_data extends CI_Model
{
// Your functions here
}
并将您的模型命名为all_sensor_date.php并将其放在ci中的模型文件夹中。
现在，如果你在你的控制器中调用它，它肯定会起作用。
关于错误报告，请转到主 index.php 文件，即与ci中的应用程序文件夹位于同一目录中并检查已定义的环境，确保将其设置为< b>开发报告所有错误。
编辑：
这里有一个错误
$this->load->model('All_sensor_data'); //您在此处使用了类名来加载模型
改为使用
$this->load->model('all_sensor_data'); //加载模型时使用文件名
