问题描述
CakePHP 3.8.13-我有一个表模型，该模型可以从表中检索相关数据并将其删除，但是在更新/添加条目时，由于某种原因它不会更改此数据。因此，这似乎是一个正确的设置，但是并没有更新/添加它们。简而言之，它是一个“问题”表和一个“分区”表，以及一个名为“ questions_divisions”的关系表。在此关系表中，有一个question_id和division_id列。如果我在那里手动添加或删除条目，一切似乎都可以。仅当执行patchEntity和保存时，它不会这样做。这是发布数据：
'name' => string 'Some name' (length=8)
'questiontype_id' => string '1' (length=1)
'extra' => string '' (length=0)
'answer' => string '' (length=0)
'datafield' => string 'Person.firstname' (length=16)
'divisions' =>
array (size=1)
'_ids' =>
array (size=3)
0 => string '1' (length=1)
1 => string '7' (length=1)
2 => string '5' (length=1)
这是执行的代码（因此上面的发布数据是$ this-> request-> getData（））：
$question = $this->Questions->patchEntity($question,$this->request->getData());
if ($this->Questions->save($question)) {
对于不同的模型，所有这些或多或少都与应用程序中其他地方发生的相同，实际上是在添加/更新除法。我还清除了/ tmp / cache，以防万一，似乎没有达到目的。我在这里茫然。
这是整个表格模型：

解决方法
似乎就像在$ _accessible数组中（在Model / Entity内部）添加此列可以解决问题……这就是为什么它可以检索数据但不编辑它的原因-也许是“可访问的”？不确定这是否是正确的名称，但是。.
protected $_accessible = [
'name' => true,'extra' => true,'answer' => true,'datafield' => true,'questiontype_id' => true,'questiontype' => true,'activities' => true,'bookingforms' => true,'divisions' => true // this did the trick!
];
