我的学校模型与many to many
表加入的属性模型有attribute_school
关系。
在我的 Shell 文件夹中,我的主要功能是
$schoolsRaw = TableRegistry::get('Schools');
$schools = $schoolsRaw->find('all', [
'fields' => [
'Schools.name',
'Schools.logo',
'Schools.discount'
],
'contain' => [
'Users'=> [
'fields' => [
'Users.first_name',
'Users.last_name',
'Users.email',
'Users.title'
]
],
'Attributes' => [
'fields' => [
'Attributes.model'
]
]
]
]);
echo debug(json_encode($schools , JSON_PRETTY_PRINT));
以上echo命令会为学校记录的所有实例生成空值,如下所示:
{
"name": "Genesis School",
"logo": "badges\/genesis.jpg",
"discount": "Not Stated",
"attributes": [],
"user": {
"first_name": "xxxxx",
"last_name": "yyyyy",
"email": "mynane@yahoo.co.uk",
"title": "Ms"
}
我的模特:
//schools
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('schools');
$this->setDisplayField('name');
$this->setPrimaryKey('id');
$this->belongsTo('Users', [
'foreignKey' => 'user_id',
'joinType' => 'INNER'
]);
$this->belongsToMany('Attributes', [
'foreignKey' => 'school_id',
'targetForeignKey' => 'attribute_id',
'joinTable' => 'attributes_schools'
]);
}
// attributes model
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('attributes');
$this->setDisplayField('name');
$this->belongsToMany('Schools', [
'foreignKey' => 'attribute_id',
'targetForeignKey' => 'school_id',
'joinTable' => 'attributes_schools'
]);
}
// join table
public function initialize(array $config)
{
parent::initialize($config);
$this->primaryKey('id');
$this->setTable('attributes_schools');
$this->belongsTo('Schools', [
'foreignKey' => 'school_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Attributes', [
'foreignKey' => 'attribute_id',
'joinType' => 'INNER'
]);
}
这是cakephp 3.4,我不知道为什么它没有获取属性记录,也没有记录错误。请帮忙
