Vui lòng thử cái này:
db.Product.findOneAndUpdate(
{ _id: 123 },
{
$set: {
'variations.$[item].valueList.$[nameField].value': 'newRed',
'variations.$[item].picture': 'newURL' // item is each object in variations which is being checked in arrayFilters.
}
},
{
arrayFilters: [{ 'item.valueList.value': 'oldRed' }, { 'nameField.value': 'oldRed' }],
new: true
}
)
Dữ liệu bộ sưu tập:
{
"_id" : 123,
"variations" : [
{
"id" : 1,
"picture" : "https://example.picture.com",
"valueList" : [
{
"name" : "color",
"value" : "oldRed"
},
{
"name" : "size",
"value" : "M"
},
{
"name" : "color",
"value" : "oldRed"
}
]
},
{
"id" : 2,
"picture" : "https://example.picture.com",
"valueList" : [
{
"name" : "color",
"value" : "black"
},
{
"name" : "size",
"value" : "M"
}
]
},
{
"id" : 3,
"picture" : "https://example3.picture.com",
"valueList" : [
{
"name" : "color",
"value" : "oldRed"
},
{
"name" : "size",
"value" : "M"
}
]
}
]
}
Kết quả:
/* 1 */
{
"_id" : 123,
"variations" : [
{
"id" : 1,
"picture" : "newURL",
"valueList" : [
{

},
{

"value" : "newRed"
}
]
},
{
