扩展ModuleAdminController添加/编辑不起作用

Question

所以这似乎是一个非常愚蠢的问题，基本上是教科书的实施。但是当使用renderList（）创建的“添加/编辑”按钮时，提交的字段为空。我已进入核心ObjectModel类并输出结果，实际上没有数据传回。从我所知道的，所有这些都应该链接起来，因为所有这些都是由后端生成/处理的，但显然遗漏了一些东西。

class AdminStoreMatrixController extends ModuleAdminController {
protected $actions_available = array('edit', 'delete');//, 'details');
protected $actions = array('edit', 'delete');//, 'details');
protected $position_identifier = 'id_store_matrices';

public function __construct() {

    $this->context = Context::getContext();
    $this->table = 'store_matrices';
    $this->identifier = 'id_store_matrices';
    $this->className = 'StoreMatrix';
    $this->lang = false;

    $this->fields_list = array(
        'id_store_matrices' => array('title' => $this->l('#')),
        'price_low' => array('title' => $this->l('Price Low')),
        'price_high' => array('title' => $this->l('Price High')),
        'apr' => array('title' => $this->l('APR')),
        'apr_term' => array('title' => $this->l('APR Term')),
        'down_payment' => array('title' => $this->l('Down Payment')),
        'shipping' => array('title' => $this->l('Shipping')),
    );

    // This adds a multiple deletion button
    $this->bulk_actions = array(
        'delete' => array(
            'text' => $this->l('Delete selected'),
            'confirm' => $this->l('Delete selected items?')
        )
    );
    parent::__construct();
}


// This method generates the list of results
//public function renderList() {
//  $this->addRowAction('edit');
//  $this->addRowAction('delete');
    //$this->addRowAction('details');
//  return parent::renderList();
//}

// This method generates the Add/Edit form
public function renderForm() {
    // Building the Add/Edit form
    $this->fields_form = array(
        'legend' => array(
            'title' => $this->l('Store Matrices')
        ),
        'input' => array(

            ),
            array(

                'required' => true,
                'desc' => $this->l('Highest price this will apply too'),
            ),
            array(

Model storematrix.php

Answer 1

因此，prestashop中模型的问题在于，您不仅需要拥有字段的定义，而且还必须将字段声明为上面的公共字段。见下文，现在一切都很完美。

class StoreMatrix extends ObjectModel {
    //fields to store into the database
    public $price_low;
    public $price_high;
    public $apr;
    public $apr_term;
    public $down_payment;
    public $shipping;

     /* 
     *//**
     * @see ObjectModel::$definition
     */
    public static $definition = array(
        'table' => 'store_matrices',
        'primary' => 'id_store_matrices',
        'fields' => array(
            'price_low' =>          array('type' => self::TYPE_FLOAT,   'validate' => 'isFloat',    'required' => true, 'size' => 10),
            'price_high' =>         array('type' => self::TYPE_FLOAT,   'validate' => 'isFloat',    'required' => true, 'size' => 10),
            'apr' =>                array('type' => self::TYPE_FLOAT,   'validate' => 'isFloat',    'required' => true, 'size' => 10),
            'apr_term' =>           array('type' => self::TYPE_INT,     'validate' => 'isInt',      'required' => true, 'size' => 10),
            'down_payment' =>       array('type' => self::TYPE_FLOAT,   'validate' => 'isFloat',    'required' => true, 'size' => 10),
            'shipping' =>           array('type' => self::TYPE_FLOAT,   'validate' => 'isFloat',    'required' => true, 'size' => 10),
        ),
    );
}
