我想查找并删除该值,我的 id是“ 5cc6d9737760963ea07de411”
我的数据:
[
{
"products" : [ {
"id" : "5cc6d9737760963ea07de411",
"quantity" : 1,
"totalPrice" : 100,
},
{
"id" : "5cc6d9737760963ea07de412",
"quantity" : 2,
"totalPrice" : 200,
}
],
"isCompleted" : false,
"_id" : "5cc7e4096d7c2c1f03570a2f"
},
{
"products" : [{
"id" : "5cc6d9737760963ea07de414",
"quantity" : 1,
"totalPrice" : 100,
},
{
"id" : "5cc6d9737760963ea07de4133",
"quantity" : 2,
"totalPrice" : 200,
}
],
"isCompleted" : false,
"_id" : "5cc7e4096d7c2c1f03570a2f"
}
]
我尝试过:
Schema.findOneAndUpdate({"products.id": "5cc6d9737760963ea07de411"},
{ $pull: {"products.$.id": "5cc6d9737760963ea07de411" })
但是它不起作用。
答案 0 :(得分:2)
现在,您无需使用.dot
表示法。相反,您需要使用“绝对”对象结构:
Schema.findOneAndUpdate(
{ "products.id": "5cc6d9737760963ea07de411" },
{ "$pull": { "products": { "id": "5cc6d9737760963ea07de411" }}}
)
