在 CakePHP 3 中调用布尔值的成员函数 format()

Question

我正在使用 CakePHP 3.4

我使用

从 LogProfileVisits table 获取访问者数量

$profile_visit_logs = $this->Users->LogProfileVisits->find()
   ->where(['user_id' => $user->id]);
$profile_visit_logs->select([
   'total_count' => $profile_visit_logs->func()->count('id'),
   'unique_count' => $profile_visit_logs->func()->count('DISTINCT `ip_address`'),
   'visit_date' => 'MONTH(created)'
])
->group('visit_date')
->limit(10);

但这是致命错误

Error: Call to a member function format() on boolean
File /path_to_app/vendor/cakephp/chronos/src/Traits/FrozenTimeTrait.php
Line: 161

同样适用于 DATE(created) 和 YEAR(created)

Answer 1

试试这个代码，这样它就知道要使用什么模型：

    $this->loadModel('LogProfileVisits');

Answer 2

查看堆栈跟踪，ORM 似乎将 visit_date 列视为 DATE 类型，您可以通过调用 DateType::toPHP() 的行来判断：

Cake\Database\Type\DateType::toPHP() - CORE/src/Database/Type/DateType.php, line 90

这是开始出错的地方，数字 5（MONTH(created) 的结果）不是有效的日期时间值，因此您最终得到 null 值，然后在尝试对其调用方法时导致致命错误：

Warning (2): DateTimeImmutable::modify() [...] Failed to parse time string (5)

DATE()或YEAR()的结果是有效的，前者显然return一个可解析的日期，后者是一个年份，这可能不明显，但可以也会被解析，但它会被视为时间值，例如 2017 将被解释为 20:17。您最终会得到一个 useless/wrong 日期对象，但它不会出错。

http://www.php.net/manual/en/datetimeimmutable.modify.php

长话短说，您需要弄清楚为什么 ORM 将列视为 DATE 类型。这肯定不是默认设置，默认情况下 computed/virtual 列将被视为字符串。如果 visit_date 不是您在评论中所说的现有列，那么它可能曾经是一个列，并且您还没有清除缓存！？

应该没有必要解决这个问题，这应该可以在您这边得到妥善解决。悬停您可以尝试更改 select/typemap 以查看它是否有任何不同，您还应该尝试在整个控制流程中对其进行调试，以便了解可能出现问题的地方：

$query->getSelectTypeMap()->addDefaults(['visit_date' => 'integer']);

$query->getTypeMap()->addDefaults(['visit_date' => 'integer']);
