我正在使用cake
PHP版本3.x.
当我查询MessagesTable时,我想获取发件人和邮件接收者的用户数据.我已经在cakePHP 2中多次这样做但我无法弄清楚为什么它在版本3.x中不起作用.
我有一个UsersTable和一个MessagesTable.
UsersTable
- $this->hasMany('Messages');
MessagesTable
- $this->belongsTo('Users',[
- 'foreignKey' => 'sender_id','propertyName' => 'Sender',]);
- $this->belongsTo('Users',[
- 'foreignKey' => 'user_id','propertyName' => 'Receiver'
- ]);
这是我正在使用的查询
- $messages = $this->Messages->find()
- ->where(['Messages.user_id' => $this->Auth->user('id')])
- ->orwhere(['Messages.sender_id' => $this->Auth->user('id')])
- ->order(['Messages.created' => 'DESC'])
- ->contain([
- 'Users.Pictures',]);
我收回了Receiver数据,但也没有收到Sender数据.任何帮助将非常感激
你的关联是错的.如果对多个关联使用相同的模型,则需要使用不同的别名和className属性(就像在CakePHP 2中一样)： –
- $this->belongsTo('Sender',[
- 'className' => 'Users','foreignKey' => 'sender_id','propertyName' => 'sender',]);
- $this->belongsTo('Receiver','foreignKey' => 'user_id','propertyName' => 'receiver'
- ]);
在您的示例代码中,Receiver会覆盖User的关联,因此您只能在结果中看到Receiver模型.
您的查询需要是这样的： –
- $messages = $this->Messages->find()
- ->where(['Messages.user_id' => $this->Auth->user('id')])
- ->orwhere(['Messages.sender_id' => $this->Auth->user('id')])
- ->order(['Messages.created' => 'DESC'])
- ->contain([
- 'Receivers' => ['Pictures'],'Senders' => ['Pictures']
- ]);
