[英]HABTM bridge data not saving
This is my first attempt at a HABTM in CakePHP and it's not going as well as I'd hoped. 这是我第一次在CakePHP中尝试HABTM,但进展并不理想。
I have table foos
and table bars
. 我有表foos
和表bars
。 When a foo
gets saved, I want to associate several bars
with it. 当一个foo
被保存时,我想与它关联几个bars
。 I am attempting to do this with the bars_foos
bridge. 我正在尝试使用bars_foos
桥进行此bars_foos
。
I'm wanting to be able to save in a way that I can pass a foo
along with a bunch of bars
something like: 我希望能够以一种可以传递foo
以及一堆bars
的方式进行保存,例如:
array(2) {
["Foo"]=> array(1) {
["name"]=> string(7) "someFoo"
}
["Bar"]=> array(4) {
[0]=> array(1) {
["ID"]=> int(3)
}
[1]=> array(1) {
["ID"]=> int(9)
}
[2]=> array(1) {
["ID"]=> int(4)
}
[3]=> array(1) {
["ID"]=> int(15)
}
}
}
lets say someFoo
gets created with ID 9... I'd want the following records would be added to the bars_foos
table: 可以说创建了ID为9的someFoo
...我希望将以下记录添加到bars_foos
表中:
+--------+----------+
| bar_ID | foo_ID |
+--------+----------+
| 3 | 9 |
| 9 | 9 |
| 4 | 9 |
| 15 | 9 |
+--------+----------+
Currently nothing is happening in the bars_foos
table, only the foos
table is getting updated with the newly created "someFoo". 当前, bars_foos
表中什么都没有发生,只有foos
表被新创建的“ someFoo”更新。 The only time that this bridge should ever get updated is when creating a new Foo
唯一应该更新此网桥的时间是在创建新Foo
I attempted to follow the CakePHP documentation with my model: 我试图用我的模型遵循CakePHP文档 :
class Foo extends AppModel {
public $primaryKey = "ID";
public $hasAndBelongsToMany = array(
'Bar' =>
array(
'className' => 'Bar',
'joinTable' => 'bars_foos',
'foreignKey' => 'foo_ID',
'associationForeignKey' => 'bar_ID'
)
);
}
and using this in my controller... 并在我的控制器中使用它...
$this->Foo->saveAll($data); //$data looks like the Array above in the first code block
I've also tried with my $data
in these formats based on things I've seen in searching for a solution: 我还根据在搜索解决方案中看到的内容尝试了以下格式的$data
:
array(1) {
["Foo"]=> array(3) {
["name"]=> string(7) "FooName"
["Bar"]=> array(2) {
[0]=> array(1) {
["ID"]=> int(3)
}
[1]=> array(1) {
["ID"]=> int(2)
}
}
}
}
and 和
array(2) {
["Foo"]=> array(1) {
["name"]=> string(7) "fooName"
}
["Bar"]=> array(1) {
["Bar"]=> array(2) {
[0]=> array(1) {
["ID"]=> int(3)
}
[1]=> array(1) {
["ID"]=> int(2)
}
}
}
}
and got the same result (new foo
gets created, but nothing gets inserted in the bars_foos
table) 并得到相同的结果(创建了新的foo
,但未在bars_foos
表中插入任何bars_foos
)
Finally got it working. 终于成功了。 It seems we should not explicitly put in the ID keys for the related table. 看来我们不应该显式地输入相关表的ID键。 This format worked for me: 这种格式对我有用:
array(2) {
["Foo"]=>
array(1) {
["name"]=> string(7) "fooName"
}
["Bar"]=> array(1) {
["Bar"]=> array(4) {
[0]=> int(3)
[1]=> int(2)
[2]=> int(9)
[3]=> int(7)
}
}
}
and that gives me my desired result in the bridge table: 这在桥接表中给了我我想要的结果:
+--------+----------+
| bar_ID | foo_ID |
+--------+----------+
| 3 | 9 |
| 2 | 9 |
| 9 | 9 |
| 7 | 9 |
+--------+----------+
This also seems to have the same effect (not nesting the Bar id's twice) 这似乎也有相同的效果(不是两次嵌套Bar ID)
array(2) {
["Foo"]=>
array(1) {
["name"]=> string(7) "fooName"
}
["Bar"]=> array(4) {
[0]=> int(3)
[1]=> int(2)
[2]=> int(9)
[3]=> int(7)
}
}
