I'm new at power automate. Im puzzled about accessing property or value from Append to array variable like the "pr_no" using variables('PRNoRows')[value]['pr_no'] but i can't get it done. Please see below the result of the array. I am gladly happy if someone knows any approaces on how to get the properties of the array. Thank you.
{
"name": "PRNoRows",
"value": {
"#odata.context": "https://asia-001.azure-apim.net/apim/sql/409448f6faf34be39bbfc/$metadata#datasets('default%2Cdefault')/tables('%5Bdbo%5D.%5BvwithPayment%5D')/items",
"value": [
{
"#odata.etag": "",
"ItemInternalId": "906fe260-c67a-49fb-a32e-f6facf75c907",
"id": 8259,
"control_number": "P-CR003920",
"cr_date": "2021-12-13T00:00:00Z",
"company_id": 1,
"code_count": 3920,
"cr_no": "CR# 03320",
"pr_no": "25342",
"pr_date": "12/10/2021"
}
]
}
}
The value property has [], which means it is an array within an array. You can use an index to retrieve the pr_no of a specific item of the array.
Try the following expression (this will retrieve the pr_no value of the first item in the value property of the first item in your array variable)
variables('PRNoRows')[0]['value'][0]['pr_no']

I have some json data that I would like to filter in a Power Automate Flow.
A simplified version of the json is as follows:
[
{
"ItemId": "1",
"Blah": "test1",
"CustomFieldArray": [
{
"Name": "Code",
"Value": "A"
},
{
"Name": "Category",
"Value": "Test"
}
]
},
{
"ItemId": "2",
"Blah": "test2",
"CustomFieldArray": [
{
"Name": "Code",
"Value": "B"
},
{
"Name": "Category",
"Value": "Test"
}
]
}
]
For example, I wish to filter items based on Name = "Code" and Value = "A". I should be left with the item with ItemId 1 in that case.
I can't figure out how to do this in Power Automate. It would be nice to change the data structure, but this is the way the data is, and I'm trying to work out if this is possible in Power Automate without changing the data itself.
Firstly, I had to fix your JSON, it wasn't complete.
Secondly, filtering on sub array information isn't what I'd call easy. However, to get around the limitations, you can perform a bit of trickery.
Prior to the step above, I create a variable of type Array and called it Array.
In the step above, the left hand side expression is ...
string(item()?['CustomFieldArray'])
... and the contains comparison on the right hand side is simply as you can see, a string with the appropriate filter value ...
{"Name":"Code","Value":"A"}
... it's not an expression or a proper object, just a string.
If you need to enhance it to cater for case sensitive values, just set everything to lower case using the toLower expression on the left.
Although it's hard to see, that will produce your desired result ...
... you can see by the vertical scrollbars that it's reduced the size of the array.
I have an JSON object with the structure below. When looping over key_two I want to create a new object that I will return. The returned object should contain a title with the value from key_one's name where the id of key_one matches the current looped over node from key_two.
Both objects contain other keys that also will be included but the first step I can't figure out is how to grab data from a sibling object while looping and match it to the current value.
{
"key_one": [
{
"name": "some_cool_title",
"id": "value_one",
...
}
],
"key_two": [
{
"node": "value_one",
...
}
],
}
This is a good example of a 'join' operation (in SQL terms). JSONata supports this in a path expression. See https://docs.jsonata.org/path-operators#-context-variable-binding
So in your example, you could write:
key_one#$k1.key_two[node = $k1.id].{
"title": $k1.name
}
You can then add extra fields into the resulting object by referencing items from either of the original objects. E.g.:
key_one#$k1.key_two[node = $k1.id].{
"title": $k1.name,
"other_one": $k1.other_data,
"other_two": other_data
}
See https://try.jsonata.org/--2aRZvSL
I seem to have found a solution for this.
[key_two].$filter($$.key_one, function($v, $k){
$v.id = node
}).{"title": name ? name : id}
Gives:
[
{
"title": "value_one"
},
{
"title": "value_two"
},
{
"title": "value_three"
}
]
Leaving this here if someone have a similar issue in the future.
In Elasticsearch, I have an object that contains an array of objects. Each object in the array have type, id, updateTime, value fields.
My input parameter is an array that contains objects of the same type but different values and update times. Id like to update the objects with new value when they exist and create new ones when they aren't.
I'd like to use Painless script to update those but keep them distinct, as some of them may overlap. Issue is that I need to use both type and id to keep them unique. So far I've done it with bruteforce approach, nested for loop and comparing elements of both arrays, but I'm not too happy about that.
One of the ideas is to take array from source, build temporary HashMap for fast lookup, process input and later store all objects back into source.
Can I create HashMap with custom object (a class with type and id) as a key? If so, how to do it? I can't add class definition to the script.
Here's the mapping. All fields are 'disabled' as I use them only as intermidiate state and query using other fields.
{
"properties": {
"arrayOfObjects": {
"properties": {
"typ": {
"enabled": false
},
"id": {
"enabled": false
},
"value": {
"enabled": false
},
"updated": {
"enabled": false
}
}
}
}
}
Example doc.
{
"arrayOfObjects": [
{
"typ": "a",
"id": "1",
"updated": "2020-01-02T10:10:10Z",
"value": "yes"
},
{
"typ": "a",
"id": "2",
"updated": "2020-01-02T11:11:11Z",
"value": "no"
},
{
"typ": "b",
"id": "1",
"updated": "2020-01-02T11:11:11Z"
}
]
}
And finally part of the script in it's current form. The script does some other things, too, so I've stripped them out for brevity.
if (ctx._source.arrayOfObjects == null) {
ctx._source.arrayOfObjects = new ArrayList();
}
for (obj in params.inputObjects) {
def found = false;
for (existingObj in ctx._source.arrayOfObjects) {
if (obj.typ == existingObj.typ && obj.id == existingObj.id && isAfter(obj.updated, existingObj.updated)) {
existingObj.updated = obj.updated;
existingObj.value = obj.value;
found = true;
break;
}
}
if (!found) {
ctx._source.arrayOfObjects.add([
"typ": obj.typ,
"id": obj.id,
"value": params.inputValue,
"updated": obj.updated
]);
}
}
There's technically nothing suboptimal about your approach.
A HashMap could potentially save some time but since you're scripting, you're already bound to its innate inefficiencies... Btw here's how you initialize & work with HashMaps.
Another approach would be to rethink your data structure -- instead of arrays of objects use keyed objects or similar. Arrays of objects aren't great for frequent updates.
Finally a tip: you said that these fields are only used to store some intermediate state. If that weren't the case (or won't be in the future), I'd recommend using nested arrays to enable querying independently of other objects in the array.
I'm trying to read individual value from be json array object to display in the page. I have tried with below code but couldn't make it. Please advise what am i doing wrong here.
Apperciate your help.
You can get the length of a JavaScript array via its property length. To access the array Reference in your object, you can use dot notation.
In combination, the following should do what you expect:
var obj = {
"Reference": [
{
"name": "xxxxxxxx",
"typeReference": {
"articulation": 0,
"locked": false,
"createdBy": {
"userName": "System",
},
"lastModifiedBy": {
"userName": "System",
},
"lastModified": 1391084398660,
"createdOn": 1391084398647,
"isSystem": true
},
...
},
...
]
};
console.log(obj.Reference.length);
In case you are actually dealing with a JSON string, not a JavaScript object, you will need to parse it first via JSON.parse().
You get the length of an array by simply access the length attribute.
For example [0,1,2,3].length === 4.
If you just want to loop through the array, use forEach or map instead of a for loop. It's safer, cleaner, less hassle and you don't meed to know the length.
E.g.
[0,1,2,3].forEach(num => console.log(num))
I am developing a web app using Codeigniter and MongoDB.
In the database I got a document that look like this:
{
"_id": {
"$id": "4f609932615a935c18r000000"
},
"basic": {
"name": "The project"
},
"members": [
{
"user_name": "john",
"role": "user",
"created_at": {
"sec": 1331730738,
"usec": 810000
}
},
{
"user_name": "markus",
"role": "user",
"created_at": {
"sec": 1331730738,
"usec": 810000
}
}
]
}
I need to search this document using both user_name and role. Right now when I am using the below code I get both. I only want to get array items matching both user_name and role.
$where = array (
'_id' => new MongoId ($account_id),
'members.user_id' => new MongoId ($user_id),
'members.role' => $role
);
$this -> cimongo -> where ($where) -> count_all_results ('accounts');
This is an old question, but as of MongoDB 2.2 or so you can use the $ positional operator in a projection so that only the matched array element is included in the result.
So you can do something like this:
$this->cimongo->where($where)->select(array('members.$'))->get('accounts');
This is a repeat of this question:
Get particular element from mongoDB array
Also you might want to use $elemMatch
http://www.mongodb.org/display/DOCS/Advanced+Queries#AdvancedQueries-ValueinanArray
Here is the rub -- you aren't going to be able to get the array items that match because mongo is going to return the entire document if those elements match. You will have to parse out the code client side. Mongo doesn't have a way to answer, "return only the array that matches."
