我需要使用ajax将数据相应地插入到这些表中。首先,我将数组数据结构化为以下内容
这是我的数据
[
'quantity' => 3,
'price' => 63,
'payment_method_id' => 1,
'user_id' => 1,
'sale_details' => [
0 => [
'product_id' => 1,
'quantity' => 2,
'price' => 24,
'total_price' => 48
],
1 => [
'product_id' => 49,
'quantity' => 1,
'price' => 15,
'total_price' => 15
]
]
]
SalesController.php
if ($this->request->is('ajax')) {
$sales = $this->Sales->newEntity(
$this->request->data(),
[
'validate' => 'create',
'associated' => [
'SaleDetails' => ['validate' => 'create']
]
]
);
if ($this->Sales->save($sales)) {
//code
}
}
我设法将数据插入到这些表中,但这两个表的主键随着2的增加而不断增加。我插入了3次数据。以下是数据的记录方式:-

正如您从表中注意到的,sales表id随着2的增加而增加,sale\u details表也是如此
我的问题如下:-
1) 我是CakePHP3的新手,所以这是将数据保存到多个表中的正确方法吗?我删除了以下几行,仍然能够将数据保存到这些表中。如何处理此处的“关联”
SalesController.php
if ($this->request->is('ajax')) {
$sales = $this->Sales->newEntity(
$this->request->data(),
[
'validate' => 'create',
/*'associated' => [
'SaleDetails' => ['validate' => 'create']
]*/ // removed
]
);
if ($this->Sales->save($sales)) {
//code
}
}
2) 我不明白为什么那些id会随着2的增加而增加。我很确定我已经为这两个表设置了auto_increment=1
系统变量auto\u increment\u increment
已设置为2。但我不知道这是怎么发生的
提前感谢。是的,这是保存关联的正确方法 即使未通过
associated
选项指定关联,您的关联仍在转换(并因此保存),因为默认情况下允许一级关联,即在删除该选项时,可以转换所有一级关联,并且在指定该选项时,如示例所示,只能转换SaleDetails
关联
引用文件:
默认情况下,此表上的所有关联都将水合。您可以使用options参数限制生成的关联,或包括更深的关联
保存实体时,还可以选择保存部分或所有关联实体。默认情况下,将保存所有第一级实体
