好的,我有这个系列:
{
"_id" : ObjectId("59baa8af86e5df3984674639"),
"centralPath" : "C:\\Users\\konrad.sobon\\OneDrive - HOK\\GoogleDrive\\Work\\DynamoWork\\142_SeatManifestGenerator\\RVT2018\\CBUEC_HOK_IN-central.rvt",
"totalFamilies" : 31,

"createdOn" : ISODate("2017-09-14T20:19:09.525Z"),
"families" : [
{
"name" : "Spot Elevation - Target Filled_HOK_I",
"size" : "1.2Mb",
"sizeValue" : 1200000,
"instances" : 0,
"elementId" : 6158,
"isFailingChecks" : true,
"isDeleted" : false,
"_id" : ObjectId("59bae43d2720015998392905"),
"tasks" : [],
"parametersCount" : 0,
"nestedFamilyCount" : 1,
"voidCount" : 0,
"refPlaneCount" : 2,
"arrayCount" : 0
},
{
"name" : "Section Head - Filled_HOK_I",
"size" : "140kb",
"sizeValue" : 145760,
"instances" : 0,
"elementId" : 8762,
"isFailingChecks" : true,
"isDeleted" : false,
"_id" : ObjectId("59bae43d2720015998392904"),
"tasks" : [],
"parametersCount" : 0,
"nestedFamilyCount" : 1,
"voidCount" : 0,

"arrayCount" : 0
},
{
"name" : "Railing Tag_HOK_I",
"size" : "244kb",
"sizeValue" : 249856,
"instances" : 0,
"elementId" : 12426,
"isFailingChecks" : true,
"isDeleted" : false,
"_id" : ObjectId("59bae43d2720015998392903"),
"tasks" : [],
"parametersCount" : 3,

},
{

"_id" : ObjectId("59bae43d27200159983928e7"),
"tasks" : [],
"parametersCount" : 4,
"nestedFamilyCount" : 2,
"voidCount" : 0,
"refPlaneCount" : 18,
"arrayCount" : 0
}
],
"__v" : 0
}
我要做的是发送更新该集合中某些“家庭”的请求。我有这些Family对象的数组,如下所示:
{"key": [
{
"name" : "New Spot Elevation - Target Filled_HOK_I",
"size" : "1.2Mb",
"sizeValue" : 1200000,
"instances" : 0,
"elementId" : 6158,
"isFailingChecks" : true,
"isDeleted" : false,
"Id" : "59bae43d2720015998392905",
"tasks" : [],
"parametersCount" : 0,
"nestedFamilyCount" : 1,
"voidCount" : 0,
"refPlaneCount" : 2,
"arrayCount" : 0
},
{
"name" : "New Section Head - Filled_HOK_I",
"size" : "140kb",
"sizeValue" : 145760,
"instances" : 0,
"elementId" : 8762,
"isFailingChecks" : true,
"isDeleted" : false,
"Id" : "59bae43d2720015998392904",
"tasks" : [],
"parametersCount" : 0,
"nestedFamilyCount" : 1,
"voidCount" : 0,
"refPlaneCount" : 3,
"arrayCount" : 0
}
]}
现在,我需要能够找到并更新每个指定的系列。我以为我可以迭代传入的数组(我在req.body中发送它),然后创建一个需要更新的ID数组,这样我就可以在mongo中使用$ in运算符了。之后,我认为我可以使用id来检索我感兴趣的属性,并使用$ set来更新它们。我的尝试在这里:
module.exports.updateMultipleFamilies = function (req, res) {
var id = req.params.id;
var famIds = []; // [ObjectId]
var newFamilies = {}; // {"id_string" : family}
for(var key in req.body) {
if(req.body.hasOwnProperty(key)){
for(var i = 0; i < req.body[key].length; i++){
var family = req.body[key][i];
newFamilies[family.Id] = family;
famIds.push(mongoose.Types.ObjectId(family.Id));
}
}
}
Families
.updateMany(
{_id: id, 'families._id': {$in: famIds}},
{$set: {'name': newFamilies["current_document_id_help"].name}}, function(err, result){
if(err) {
res
.status(400)
.json(err);
} else {
res
.status(202)
.json(result);
}
}
)
};
编辑:
所以我尝试了bulkWrite
调用的不同方法。它不会给我错误,但它也不会更新任何内容。有什么想法吗?
module.exports.updateMultipleFamilies1 = function (req, res) {
var id = req.params.id;
var bulkOps = [];
for(var key in req.body) {
if(req.body.hasOwnProperty(key)){
bulkOps = req.body[key].map(function(item){
return {
'updateOne': {
'filter': {'_id': id, 'families._id': mongoose.Types.ObjectId(item.Id)},
'update': {'$set': {'families.$.name': item.name}},
'upsert': false
}
}
})
}
}
Families.collection
.bulkWrite(
bulkOps,
{'ordered': true, w:1}, function(err, result){
if(err) {
res
.status(400)
.json(err);
} else {
res
.status(202)
.json(result);
}
})
};
答案 0 :(得分:-1)
您需要获取系列数组,更改应用程序中的代码,然后再次更新系列数组。 或者您可以尝试{$ set:{&#39;系列。$。name&#39;:newFamilies [&#34; current_document_id_help&#34;]。name} } 但我不确定这不会更新你所有的家庭
第一个解决方案:
var id = req.params.id;
yourCollation.findById(id,function(err, doc){
if(req.body.key && req.body.key.constructor === Array){
for(var i = 0; i < req.body.key.length; i++){
for(var x in doc.families ){
if(family.id === doc.families[x].id){
doc.families[x] = family;
}
}
}
}
doc.save()
})
