Cakephp 3不检索关联模型的记录
我的学校模型与我的属性模型有一个Cakephp 3不检索关联模型的记录,php,cakephp,cakephp-3.x,cakephp-3.4,Php,Cakephp,Cakephp 3.x,Cakephp 3.4,我的学校模型与我的属性模型有一个many-to-many关系,属性模型由attribute\u-school表连接。 在cron作业的Shell文件夹中,我的主要功能包括: $schoolsRaw = TableRegistry::get('Schools'); $schools = $schoolsRaw->find('all', [ 'fields' => [ 'Schools.name', 'Schools.logo',
many-to-many
关系,属性模型由attribute\u-school
表连接。
在cron作业的Shell文件夹中,我的主要功能包括:
$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));
上面的echo命令不断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"
}
我的型号:
//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CakePHP3.4,我不知道为什么它不获取属性记录,也不记录错误。请帮助是否有任何相关属性?检查表中的键。还要检查生成的SQL查询。如果没有例外,绑定通常是正确的。另外,为什么不在旧的数组符号上使用查询生成器呢?是否有任何相关的属性?检查表中的键。还要检查生成的SQL查询。如果没有例外,绑定通常是正确的。另外,为什么不在旧的数组表示法上使用查询生成器呢?
