Laravel 5: How to saveMany() based on value
提问by user3641381
I need a little help with the following situation.
对于以下情况，我需要一些帮助。
I am willing to saveManybased on the input value. Let me give code example.
我愿意saveMany根据输入值。让我给出代码示例。
I was experimenting with the following.
我正在试验以下内容。
$data = [
'id' => 1,
'name' => 'example',
'number_of_slots' => 5,
'material' => 'Colo',
'equipment_status_code_id' => 1,
];
$platecontainer = PlateContainer::create($data);
foreach ($data as $key => $value) {
$platecontainer->containerSlots()->saveMany([
new ContainerSlot([
'plate_container_id' => $data['id'],
'slot' => $data['number_of_slots'],
'occuiped' => false,
])
]);
}
until $platecontainereverything works just great. What I want is when a PlateContaineris created using the dataarray, I want to create slots as well, but this one is based on number_of_slots
直到$platecontainer一切正常。我想要的是当PlateContainer使用data数组创建a 时，我也想创建插槽，但这个是基于number_of_slots
So for instance number_of_slotsin the example is 5so I want to save 5records in (descendingorder) in the ContainerSlottable
因此，例如number_of_slots在示例中5，我想在表中5以（降序）保存记录ContainerSlot
so the containerslots table will end up looking something like this.
所以 containerlots 表最终会看起来像这样。

The save many method accepts an array of models, so just use a forloop for the $plateContainer's number_of_slots
save many 方法接受一个模型数组，所以只需for对$plateContainer's使用循环number_of_slots
$plateContainer = PlateContainer::create($data);
$containers = [];
// Need to add one to our number of slots because
// the $i count starts at one instead of zero.
$slots = $plateContainer->number_of_slots + 1;
for($i = 1; $i < $slots; $i++) {
$containers[] = new ContainerSlot([
'plate_container_id' => $plateContainer->getKey(),
'slot' => $i,
'occuiped' => false,
]);
}
$plateContainer->containerSlots()->saveMany($containers);
