Question

CakePHP 3 ：我正在尝试更新名为 poi 的表中的外键。外表名为 poi_types 。不幸的是，DB-Designer将外键命名为 poi_type 而不是 poi_type_id 。 Cake回复

Passed variable is not an array or object, using empty array instead

我无法更改关系，因为正在运行的应用程序也会向此特定表发送请求。

任何想法，如何告诉CakePHP接受通过POST传递的值作为普通值？

修改的

视图包含以下字段：

<?= $this->Form->input('poi_type', ['options' => $poi_types_select]); ?>

on

$poi = $this->Pois->patchEntity($poi, $this->request->data);

它因上述错误而失败。删除输入字段时，一切都按预期工作。

我将外国身份证改为poi_type_id，一切都像魅力一样。

是否有任何解决方法可以说服Cake更新此字段？

关于PoiTypes的TableDefinitions

class PoiTypesTable extends Table
{

    /**
     * Initialize method
     *
     * @param array $config The configuration for the Table.
     * @return void
     */
    public function initialize(array $config)
    {
        $this->table('poi_types');
        $this->hasMany('poi_type_translations');
        $this->belongsTo('poi',['foreignKey' => 'poi_type']);
    }

Answer 1

我认为错误的发生是因为您的关联设置如下，Poi BelongsTo PoiType，我想这会导致Cake在名为“poi_type”的实体中构建关联的属性名称。

$poiEntity->poi_type // poi_type is expected to be an array or entity object

您需要更改实体中该关联表的名称。 See this page of the manual.您需要更改媒体资源名称。

$this->belongsTo('PoiTypes', [
    'className' => 'PoiTypes',
    'foreignKey' => 'poi_type',
    'propertyName' => 'poi_types'
]);
