使用Cake 3.2.4
我有EventTicketSales
表
这
$this->belongsToMany('Approvings', [
'className' => 'Contacts',
'joinTable' => 'event_ticket_sales_approvings',
'targetForeignKey' => 'contact_id',
'saveStrategy' => 'replace',
]);
因此,当我在EventTicketSales表中进行分页时,我只想显示Approvings中的2个字段,即Approvings.name和Approvings.company。
我尝试了以下内容:
$this->paginate["contain"] = ["Approvings"];
$this->paginate['fields'] = [
'EventTicketSales.id', 'EventTicketSales.event_id', 'EventTicketSales.billing_amount_in_sgd',
'EventTicketSales.payment_terms', 'EventTicketSales.invoice_number',
'EventTicketSales.due_date',
'Approvings.id', 'Approvings.name', 'Approvings.company'
];
我在非相关模型中收到有关JsonSerialize的错误消息。
[Exception] Failed calling App\Model\Entity\User::jsonSerialize() #0 /var/virtual/WebApps/corri/vendor/cakephp/cakephp/src/View/JsonView.php(0
我期待以下结果:(我以json格式显示)
id: "06f39ba3-9a17-47c6-9374-24b49fb64665",
event_id: 7,
billing_amount_in_sgd: 7680.03,
payment_terms: "45 days",
invoice_number: "9191",
due_date: "2016-03-05T00:00:00+0800",
approvings: [
{
id: 63,
name: "Jaime Jen",
company: "Apple Company",
_joinData: {
contact_id: 63,
id: 335,
event_ticket_sale_id: "06f39ba3-9a17-47c6-9374-24b49fb64665",
created: "2016-01-20T13:43:44+0800",
modified: "2016-01-20T13:43:44+0800"
}
}
]
答案 0 :(得分:1)
分页器fields
选项正在应用于主查询查找器,并且由于belongsToMany
分配是通过seaprate查询检索的,因此该选项不会对其产生任何影响。< / p>
相反,您必须相应地配置包含,即使用回调或fields
选项。另请注意,在限制hasMany
或belongsToMany
关联时,您还必须选择正确的外键。
$this->paginate['contain'] = [
'Approvings' => function (\Cake\ORM\Query $query) {
return $query->select([
'Approvings.id',
'Approvings.name',
'Approvings.company',
'EventTicketSalesApprovings.event_ticket_sale_id'
]);
}
];
