我正在尝试在http://book.cakephp.org/2.0/en/models/saving-your-data.html的示例代码中构建,该部分以“保存相关模型数据(hasOne,hasMany,belongsTo)”开头。但是,当我调用未设置时,我收到以下错误消息:
间接修改重载属性AppModel :: $ MealContent无效[APP \ Controller \ MealsController.php,第15行] 尝试修改非对象的属性[APP \ Controller \ MealsController.php,第15行]
当然,数据也不会保存。
如您所见,我的应用程序没有公司或帐户。相反,我有Meals和MealContents,但关系似乎已经设置相同。显然,某处存在问题,所以这里有一些代码。
Meals.php:
class Meals extends Entry {
public $hasMany = 'MealContents';
public $validate = array(
'Timestamp' => array(
'validDate' => array(
'rule' => array('garbageDateChecker'),
'required' => true,
'message' => 'The date could not be understood.'),
'noTimeTravel' => array(
'rule' => array('noTimeTravel'),
'required' => true,
'message' => 'You cannot enter times in the future.')
)
);
}
MealContents.php:
class MealContents extends Entry {
public $belongsTo = 'Meals';
public $validate = array(
'Meals_ID' => array(
'notEmpty' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'This field cannot be blank')
),
'Item_ID' => array(
'notEmpty' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'This field cannot be blank')
)
);
}
最后,控制器的index()函数:
public function index() {
$this->set('title_for_layout', "Food Log");
if ($this->request->is('post')) {
$this->Meal->create();
unset($this->Meal->MealContent->validate['Meals_ID']);
if ($this->Meal->saveAssociated($this->request->data)) {
$this->Session->setFlash('The meal was logged.');
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash("Couldn't save the meal.");
}
}
}
Entry.php
abstract class Entry extends AppModel {
public function garbageDateChecker($dateToCheck) {
date_default_timezone_set("America/Tijuana");
$result = TRUE;
try {
new DateTime($dateToCheck['Timestamp']);
} catch (Exception $e) {
$result = FALSE;
}
return $result;
}
public function noTimeTravel($dateToCheck) {
date_default_timezone_set("America/Tijuana");
$result = TRUE;
$objectifiedDateToCheck = new DateTime($dateToCheck['Timestamp']);
$currentTime = new DateTime("now");
if ($objectifiedDateToCheck > $currentTime) {
$result = FALSE;
}
return $result;
}
}
我很确定save()失败不是由于验证,因为即使我注释掉验证规则和unset()行,也不会保存数据。
很容易将其归咎于糟糕的数据或搞砸视图。但是,数据看起来还不错:
$this->request->data
--MealContents
---[0]
-----[Food_Item_ID] = "0"
--Meals
---[Comments] = ""
---[Timestamp]
-----[day] = "12"
-----[hour] = ...
当我阅读CakePHP书时,我错过了什么?
答案 0 :(得分:1)
在所有模型类声明中,您应该扩展AppModel类而不是“Entry”。此外,您需要将模型名称更改为单数名词。用餐而不是用餐。
class Meal extends AppModel {
//your model's code
}
class MealContent extends AppModel {
//your model's code
}
在你的控制器中,如果你想跳过saveAssociated调用的验证,你可以传递一个options数组,元素“validate”设置为False作为第二个参数。你不应该在你的模型上使用unset,因为它会影响你应用的其余部分。
$this->Meal->saveAssociated($this->request->data, array("validate" => false));
