MongoDB - Set field to hash of another field

Is there a way to run this query so that instead of { $toString: "$_id" } I can take the hash of the image field value for that document and set the field to that hash value?
So instead of this:
db.getCollection("test_products").updateMany( {_id: {$in: [ ObjectId('6340eae3bb965cdee37b8b30'), ObjectId('6340eae3bb965cdee37b8b33') ]}}, [
{ $set : { image : { $concat : [ "https://www.example.com/products/", { $toString: "$_id" }, ".png" ] } } }
] );
I would want something like this:
db.getCollection("test_products").updateMany( {_id: {$in: [ ObjectId('6340eae3bb965cdee37b8b30'), ObjectId('6340eae3bb965cdee37b8b33') ]}}, [
{ $set : { image : { $concat : [ "https://www.example.com/products/", { $hex_md5: "$image" }, ".png" ] } } }
] );

You will need to use $function to use js functionality for the md5 sum computation.
db.collection.update({},
[
{
"$addFields": {
"image": {
"$function": {
"body": "function(image){return \"https://www.example.com/products/\"+hex_md5(image)+\".png\"}",
"args": [
"$image"
],
"lang": "js"
}
}
}
}
],
{
multi: true
})

How to return a nested JSon object in a key value store object

I have a [simplified] JSON file like
{
"id":87,
"meta_data":[
{
"id":1232,
"key":"user_created_by",
"value":"example#gmail.com"
},
{
"id":1233,
"key":"user_created_at",
"value":"1659890457477"
},
{
"id":1234,
"key":"good_person_or_silly_sausage",
"value":"No"
}
]
}
I want to do something like
Logger.log(orderDetailsObject.meta_data.value[key="good_person_or_silly_sausage"])
The expected value would be
No
However, this isn't what's occurring. At present I'm being told that the object is null.
I think it's because the meta_data object is an object in an object or two dimensional array or something? I don't have a good understand of what I'm doing here,
I feel like
https://docs.jsonata.org/simple
and
https://docs.jsonata.org/predicate
Should be guiding me towards the answer - but I'm not getting something I think.
I'm a newbie to SO and JSON & Javascript - so please be gentle. <3

You can use the find method on the array:
const orderDetailsObject = {"id":87,"meta_data":[{"id":1232,"key":"user_created_by","value":"example#gmail.com"},{"id":1233,"key":"user_created_at","value":"1659890457477"},{"id":1234,"key":"good_person_or_silly_sausage","value":"No"}]};
console.log(orderDetailsObject.meta_data.find(
({key}) => key == "good_person_or_silly_sausage"
)?.value);

How to update subset of a string in MongoDB?

I want to update the following subset of a string in monogdb
Collection: Paper
Field: URL
Document Current:
Name : House
URL : www.home.com/300x300
Document Updated
Name : House
URL : www.home.com/600x600
I have already tried this but it doesn't seem to be working:
db.Paper.find({Name:"House"}).forEach(function(e,i) {
e.URL=e.URL.replace("300","600");
db.Paper.save(e);
});
Any ideas?

You can use one of the following aggregations to query and update:
db.test.aggregate( [
{
$match: {
url: { $regex: "300x300" }
}
},
{
$addFields: {
url: { $split: [ "$url", "300" ] }
}
},
{
$addFields: {
url: {
$concat: [
{ $arrayElemAt: [ "$url", 0 ] },
"600",
{ $arrayElemAt: [ "$url", 1 ] },
"600",
{ $arrayElemAt: [ "$url", 2 ] }
]
}
}
}
] ).forEach( doc => db.test.updateOne( { _id: doc._id }, { $set: { url: doc.url } } ) )
With MongoDB version 4.2+ you can specify the aggregation instead of an update operation with updateMany:
db.test.updateMany(
{
url: { $regex: "300x300" }
},
[
{
$addFields: {
url: { $split: [ "$url", "300" ] }
}
},
{
$addFields: {
url: {
$concat: [
{ $arrayElemAt: [ "$url", 0 ] },
"600",
{ $arrayElemAt: [ "$url", 1 ] },
"600",
{ $arrayElemAt: [ "$url", 2 ] }
]
}
}
}
]
)

Pretty simple, you have to use regex instead of string in the pattern of replace function as below:
> db.Paper.find({Name:"House"}).forEach(function (e, i) {e.URL = e.URL.replace(/300/g, "600"), printjson(e); db.Paper.save(e);} )
{
"_id" : ObjectId("5e016224a16075c5bd26fbe2"),
"Name" : "House",
"URL" : "www.home.com/600x600"
}
> db.Paper.find()
{ "_id" : ObjectId("5e016224a16075c5bd26fbe2"), "Name" : "House", "URL" : "www.home.com/600x600" }
>
So, there is a difference between e.URL.replace("300", "600") and e.URL.replace(/300/g, "600"). You should figureout it yourself.

JSON parser with Array Comma Separated Javascript

i have a JSON structure which looks like this.
"content" : {
"state" : {
"Idle" : [
[
78.366666667,
1436955825
],
[
71.281111111,
1436955840
],
[
70.41,
1436955855
],
[
74.283333333,
1436955870
],
[
76.411111111,
1436955885
]
]
} }
What i have to do is to parse this value. i have to separate comma separated value into x and y. i have to parse these values and separate them. i am having problem issue parsing them
it should look like this
"Idle" : [
{
"x" : 78.366666667,
"y" :1436955825
},
{
"x" :71.281111111,
"y" :1436955840
},
{
"x" :70.41,
"y" :1436955855
},
{
"x" :74.283333333,
"y" :1436955870
},
{
"x" :76.411111111,
"y" :1436955885
}
]

Map the ...Idle elements to objects (see MDN for Array.map):
test = {
content: {
state: {
Idle: [
[
78.366666667,
1436955825
],
[
71.281111111,
1436955840
],
[
70.41,
1436955855
],
[
74.283333333,
1436955870
],
[
76.411111111,
1436955885
]
]
}
}
};
test.content.state.Idle = test.content.state.Idle.map(
function (v) {
return { x: v[0], y: v[1] };
}
);
document.querySelector("#result").textContent = JSON.stringify(test, null, " ");
<pre id="result"></pre>

var container = {
"content": {
"state": {
"Idle": [
[
78.366666667,
1436955825
],
[
71.281111111,
1436955840
],
[
70.41,
1436955855
],
[
74.283333333,
1436955870
],
[
76.411111111,
1436955885
]
]
}
}
};
var _oldIdle = container.content.state.Idle,
_newIdle = [];
for (var i = 0; i < _oldIdle.length; i++) {
_newIdle.push({
x: _oldIdle[i][0],
y: _oldIdle[i][1]
});
}
container.content.state.Idle = _newIdle;

Try this way:
var json = {
"content": {
"state": {
"Idle": [
[
78.366666667,
1436955825
],
[
71.281111111,
1436955840
],
[
70.41,
1436955855
],
[
74.283333333,
1436955870
],
[
76.411111111,
1436955885
]
]
}
}
};
var newObj = {},
arr = [];
$.each(json.content.state.Idle, function(i, item) {
arr.push({x: item[0], y: item[1]});
});
newObj.idle = arr;
console.log(newObj);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

If you have JSON string you can use JSON.parse with reviver function
var json = '{"content":{"state":{"Idle":[[78.366666667,1436955825],[71.281111111,1436955840],[70.41,1436955855],[74.283333333,1436955870],[76.411111111,1436955885]]}}}';
var result = JSON.parse(json, function(k, v) {
if ((v instanceof Array) && (isFinite(Number(k)))) {
//if array with coordinates - return object instead
return {
x: v[0],
y: v[1]
};
}
return v;
})
console.log(result);
document.getElementById('r').innerHTML = JSON.stringify(result,null,2)
<pre id='r'></pre>

With UnderscoreJS is simple:
JSFiddle
var values = {
"content": {
"state": {
"Idle": [
[
78.366666667,
1436955825],

71.281111111,
1436955840],

]
}
}
};
var newValues = _.map(values.content.state.Idle, function (value, key) {
return {x: value[0], y: value[1]};
});
console.log(newValues);
