我是Cake
PHP的新手,以及所有关联的东西.当我想删除一个类别时,我也想删除链接到该类别的权限.这是我的桌子型号:
CategoriesTable.php
class CategoriesTable extends Table
{
public function initialize(array $config)
{
parent::initialize($config);
$this->belongsToMany('Competences');
}
}
CompetencesTable.php
class CompetencesTable extends Table
{
public function initialize(array $config)
{
parent::initialize($config);
$this->belongsToMany('Categories');
$this->belongsToMany('CategoriesCompetences');
}
}
CategoriesCompetencesTable.php
class CategoriesCompetencesTable extends Table
{
public function initialize(array $config)
{
parent::initialize($config);
$this->belongsTo('Categories');
$this->hasMany('Competences');
}
}
当我删除一个类别时,它会删除链接表中的行,但不会删除CompetenceTable中的权限.我知道我忘了一些东西,但无法弄清楚是什么.
最佳答案 我不确定为什么你的连接表中有一个hasMany assoc和Competences.有原因吗?它应该属于.如果没有尝试设置依赖关联选项=>如果是hasMany assoc,则为true.
See the documentation for hasMany().仔细阅读整个页面是个好主意.
public function initialize(array $config)
{
$this->hasMany('Competences', [
'foreignKey' => 'article_id',
'dependent' => true,
]);
}
