在 eloquent 关系中获取 parents 数据
Get parents data in eloquent relation
我有 table 这样的:
Master_Table
id titile desc
1 one one is one
2 two two is two
Child_Table
id value master_id
1 first 1
2 second 1
3 third 1
4 fourth 1
所以当我成功检索数据时,它会是一个 json 像这样:
Master_Table {
id:1,
title:'one',
desc: 'one is one',
Child_Table: [
{id: 1, value:"first", master_id:1},
{id: 2, value:"second", master_id:1},
{id: 3, value:"third", master_id:1},
{id: 4, value:"fourth", master_id:1},
]
}
我是这样做的:
$json= PDH::find(1)->products()->where('product_highlight_id', 1)->get();
但结果只有 child
Child_Table: [
{id: 1, value:"first", master_id:1},
{id: 2, value:"second", master_id:1},
{id: 3, value:"third", master_id:1},
{id: 4, value:"fourth", master_id:1},
]
我确定在 Laravel Eloquent 中可以找到它,但我很难找到它。有人可以向我指出吗?
提前致谢。
使用with()
方法:
$pdh = PDH::with('products')->where('product_highlight_id', 1)->find(1);
然后 $pdh
将包含父对象,$pdh->products
将是一个产品集合。
您不需要再次检查 product_highlight_id
,因为您已经检查过 master object
并且您有相应的 child collection
。
$json = PDH::with('products')->where('id', 1)->first();
我假设 PDH 你的主模型。
