}
}
背后的原因是什么
编辑
这是我的材质模型,它有表名和所有表字段
class Material_Model extends MY_Model
{
const DB_TABLE = 'material';
const DB_TABLE_PK = 'material_id';
public $material_id;
public $material_name;
public $size;
public $rate;
}
这是我的my_模型,它有表名和get方法来获取所有结果
class MY_Model extends CI_Model {
const DB_TABLE = 'abstract';
const DB_TABLE_PK = 'abstract';
public function get($limit = 500, $offset = 0,$desc=true) {
if ($limit) {
if ($desc)
$query = $this->db->order_by($this::DB_TABLE_PK, 'DESC')->get($this::DB_TABLE, $limit, $offset);
else
$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;
}
在型号中
public function get_data()
{
$query = $this->db->get('cake'); # get data from table
$result = $query->result_array(); # re-Assign as objective array
return $result; # return data
}
最后,我通过调用mysql查询而不是存储过程解决了我的问题
class Report extends MY_Controller{
public function item_ladger()
{
$material = $this->Material_Model->get(); // when i call it here it works fine
$inventory = $this->db->query("My Query To Database")->result_array();
$material = $this->Material_Model->get(); // now when i call it here there is no error
}
}
但当调用存储过程而不是查询时,我不清楚我的错误的严重性,
库存
函数的结果是什么?探索$this->db->query(“调用库存($id)”)
值,在您的情况下可能是TRUE
,而不是object。由$material
行库存生成的错误是mysql中的过程$inventory=$this->db->query(“调用库存($id)”->结果数组()代码>此行我调用的是mysql过程;获取我的材料后,我将材料模型加载到自动加载配置文件Inside材料模型
扩展我的材料模型所有数据库字段和表名中。在My_模型中的get
方法中,它从数据库中获取所有记录,生成并返回对象数组
class Report extends MY_Controller{
public function item_ladger()
{
$material = $this->Material_Model->get(); // when i call it here it works fine
$inventory = $this->db->query("My Query To Database")->result_array();
$material = $this->Material_Model->get(); // now when i call it here there is no error
}
}
