as lat long is coming as string but in output i want to have it as float.
i tried conversion function but couldn't get expected result. please help
me to change the lat long value into float.
Use a "modify" as your first operation to do the type conversion first, then do you shift.
Spec
[
{
"operation": "modify-overwrite-beta",
"spec": {
"lat": "=toDouble",
"lon": "=toDouble"
}
}

May be this is very basic but I am new to JOLT and I am not getting the expected output after several attempts.
I am trying to read a nested value using shift operation.
Basically the value of person is dynamic and based on this value, I need to read the value from profession object.
The input I am working on is huge and everything is working as expected, so I am just putting the part where I am stuck.
Input:
{
"person": "Tom Hanks",
"profession": {
"Tom Hanks": "actor",
"Christopher Nolan": "director"
}
}
Expected output:
{
"output" : "actor"
}
I am trying to achieve this using something like below. I know this is not correct format but just putting it to know if there is something like this which can be used to get the expected output.
[
{
"operation": "shift",
"spec": {
"#(1,profession).#(1,person)": "output"
}
}
]
Can someone please help.
Thanks in advance !!
I transformed the value as a key to match it with & operator. Maybe a more elegant way exists.
[
{
"operation": "shift",
"spec": {
"profession": "#(1,person)"
}
},
{
"operation": "shift",
"spec": {
"*": {
"&": "output"
}
}
}

I want to retrieve speed limit based on a single coordinate(of a road in the USA) using HERE REST API(not PDE). So, I only got the api_key(no app code). I searched and found some solutions which were deprecated and required the PDE api. If anybody knows the latest solution please let me know. Thanks. Anyway I got something which gives speed limit for two coordinates(not my case) and if I put the two coordinates same I get the wrong(very small) value for speed limit. which is given bellow:
https://router.hereapi.com/v8/routes?apiKey=APP_KEY&transportMode=car&origin=-37.956650,145.220673&destination=-37.956650,145.220673&spans=speedLimit&return=polyline

Is there any latest rest api service provided by Here that gives speed limit for a geo coordinate(not the pde one)?
GraphQL is a newer feature for MongoDB Stitch, and I know it is in beta, so thank you for your help in advance. I am excited about using GraphQL directly in Stitch so I am hoping that maybe I just overlooked something.
The documentation for the return Payload displays the use of bsonType, but when actually entering the JSON Schema for the payload type it asks for you to use "type" instead of "bsonType". It still works using "bsonType" to me which is odd as long as at least one of the properties uses "type".
Below is the function:
const mongodb = context.services.get("mongodb-atlas");
const collection = mongodb.db("<database>").collection("<collection>");
const query = { _id: BSON.ObjectId(input.id) }
const update = {
"$push": {
"notes": {
"createdBy": context.user.id,
"createdAt": new Date,
"text": input.text
}
}
};
const options = { returnNewDocument: true }
collection.findOneAndUpdate(query, update, options).then(updatedDocument => {
if(updatedDocument) {
console.log(`Successfully updated document: ${updatedDocument}.`)
} else {
console.log("No document matches the provided query.")
}
return {
_id: updatedDocument._id,
notes: updatedDocument.notes
}
})
.catch(err => console.error(`Failed to find and update document: ${err}`))
}
Here is the Input Type in the customer resolver:
"type": "object",
"title": "AddNoteToLeadInput",
"required": [
"id",
"text"
],
"properties": {
"id": {
"type": "string"
},
"text": {
"type": "string"
}
}
}
Below is the Payload Type:
{
"type": "object",
"title": "AddNoteToLeadPayload",
"properties": {
"_id": {
"type": "objectId"
},
"notes": {
"type": "array",
"items": {
"type": "object",
"properties": {
"createdAt": {
"type": "string"
},
"createdBy": {
"type": "string"
},
"text": {
"type": "string"
}
}
}
}
}
}
When entering the wrong "type" the error states:
Expected valid values are:[array boolean integer number null object string]
When entering the wrong "bsonType" the error states:
Expected valid values are:[string object array objectId boolean bool null regex date timestamp int long decimal double number binData]
I've tried every combination I can think of including changing all "bsonType" to "type". I also tried changing the _id to a string when using "type" or objectId when "bsonType". No matter what combination I try when I use the mutation it does what it is supposed to and adds the note into the lead, but the return payload always displays null. I need it to return the _id and note so that it will update the InMemoryCache in Apollo on the front end.
I noticed that you might be missing a return before your call to collection.findOneAndUpdate()
I tried this function (similar to yours) and got GraphiQL to return values (with String for all the input and payload types)
exports = function(input){
const mongodb = context.services.get("mongodb-atlas");
const collection = mongodb.db("todo").collection("dreams");
const query = { _id: input.id }
const update = {
"$push": {
"notes": {
"createdBy": context.user.id,
"createdAt": "6/10/10/10",
"text": input.text
}
}
};
const options = { returnNewDocument: true }
return collection.findOneAndUpdate(query, update, options).then(updatedDocument => {
if(updatedDocument) {
console.log(`Successfully updated document: ${updatedDocument}.`)
} else {
console.log("No document matches the provided query.")
}
return {
_id: updatedDocument._id,
notes: updatedDocument.notes
}
})
.catch(err => console.error(`Failed to find and update document: ${err}`))
}
Hi Bernard – There is an unfortunate bug in the custom resolver form UI at the moment which doesn't allow you to only use bsonType in the input/payload types – we are working on addressing this. In actually you should be able to use either type/bsonType or a mix of the two as long as they agree with your data. I think that the payload type definition you want is likely:
{
"type": "object",
"title": "AddNoteToLeadPayload",
"properties": {
"_id": {
"bsonType": "objectId"
},
"notes": {
"type": "array",
"items": {
"type": "object",
"properties": {
"createdAt": {
"bsonType": "date"
},
"createdBy": {
"type": "string"
},
"text": {
"type": "string"
}
}
}
}
}
}
If that doesn't work, it might be helpful to give us a sample of the data that you would like returned.
I am trying to find a substring of a string as a part of an activity in ADF. Say for instance I want to extract out the subsctring 'de' out of a string 'abcde'. I have tried:
#substring(variables('target_folder_name'), 3, (int(variables('target_folder_name_length'))-3))
where int(variables('target_folder_name_length')) has a value of 5 and variables('target_folder_name') has a value of 'abcde'
But it gives me: Unrecognized expression: (int(variables('target_folder_name_length'))-3)
On the other hand, if I try this: #substring(variables('target_folder_name'), 2, int(variables('target_folder_name_length'))-3)
This gives me: 'int' is a primitive and doesn't support nested properties
Where am I going wrong?
Use indexof. See my example below:
#substring(variables('testString'), indexof(variables('testString'), variables('de')), length(variables('de')))
Output of 'result' variable:
Since your preceding values are static, you can use below dynamic expression to achieve the substring value as per your requirement.
#substring(variables('varInputFolderName'), 3, sub(length(variables('varInputFolderName')), 3))
Where varInputFolderName = String = abcde as per this sample.
Here is the pipeline JSON payload for this sample. You can play around with it for further testing.

Lets say my json is:
{
"rating": {
"primary": {
"value": ["a","B",1]
}
}
}
What I want to achieve is:
{
"values": "a, B, 1"
}
I'm using jolt json to json code.
It is not possible with stock transformations of Jolt. You need to write your custom transformation. Check the documentation section on how to write your own transformations.
you can try the following spec
[
{
"operation": "modify-overwrite-beta",
"spec": {
"value": "=concat(#(2,rating.primary.value[0]),',',#(2,rating.primary.value[1]),',',#(2,rating.primary.value[2]))"
}
},
{
"operation": "remove",
"spec": {
"rating": ""
}
}
