I have a database like below, I want to query the accounts based on user ID.
"accounts": [
{
"applications": [
{
"appId": "sfdsfsfsfsfsfsfsfweufisfsfsfshwfkwjkf",
"creationDate": "dadasffsfsfsfsfsfsfsfsfsf",
"name": "Application one",
"users": [
{
"userId": "0Mo0J6Y7aUXdhwUszYrP5hy3k1C2"
},
{
"userId": "0Mo0J6Y7aUXdhwUwszYrP5hy3k1C2qqqqqq"
},
{
"userId": "0Mo0J6Y7aUXdhwUszYrP5hy3kqqqqqqq1C2qqqqqq"
}
]
},
{
"appId": "sfdsfsfsfsfsfsfsfweufisfsfsfshwfkwjkf",
"creationDate": "dadasffsfsfsfsfsfsfsfsfsf",
"name": "Application two",
"users": [
{
"userId": "0Mo0J6Y7aUXdhwUszYrP5hy3k1C2"
},
{
"userId": "0Mo0J6Y7aUXdhwUwszYrP5hy3k1C2qqqqqq"
},
{
"userId": "0Mo0J6Y7aUXdhwUszYrP5hy3kqqqqqqq1C2qqqqqq"
}
]
}
],
"id": "ahdagjhjfsfjgsfguwuwiuwireij",
"name": "Account ONE"
},
{
"applications": [
{
"appId": "sfdssfsfs242fsfsfsfsfsfsfweufihwfkwjkf",
"creationDate": "dadasffsfsfsfsfsfsfsfsfsf",
"name": "application one",
"users": [
{
"userId": "dadassfsfs24242424ffsfsfsfsfsfsfsfsfsf"
},
{
"userId": "0Mo0J6Y7aUXdhwUszYrP5hyaaaaaaaa3k1C2qqqqqq"
},
{
"userId": "0Mo0J6Y7aUXdhwUszYrP5haaaay3kqqqqqqq1C2qqqqqq"
}
]
}
],
"id": "ahdagjhjfsfjgsfguwuwiuwireij",
"name": "Account TWO"
}
]
}
I am new to Firebase. How can I retrieve a result from the data above where userID = '0Mo0J6Y7aUXdhwUszYrP5hy3k1C2'?
How can I get the accounts/application object?
I tried using OrderByChild/OrderBy but did not work. like
.orderBy('userId')
.equalTo('0Mo0J6Y7aUXdhwUszYrP5hy3k1C2')
.on('child_added', function(snapshot) {
var movie = snapshot.val();
console.log(JSON.stringify(movie));
});

I know how to compose JSON when you want to create a single document on FireStore.
# Query String
"updateMask.fieldPaths": [
"`price`",
"`status`"
]
# Body
"fields": {
"price": {
"stringValue": "165.00"
},
"status": {
"stringValue": "active"
}
}
But when it comes to BatchWrite I cannot understand what the doc implies
https://cloud.google.com/firestore/docs/reference/rest/v1/projects.databases.documents/batchWrite
Currently I'm doing this with Python library I deployed on cloud computing resource(pipedream) but I want to do this within Make.com and its "Make API Call" module so I need to know the curl style or REST JSON syntax.
I'm assuming fields go to "writes" but not sure what goes to "labels" object.
Exactly what's the write structure for this call?
{
"writes": [
{
"update": {
"name": "projects/project_id/databases/(default)/documents/service_order/352003090342435.5f357270173e8c70878.-9486573",

If there is null you need to change the intended value type to nullValue.
My Stepfunction is supposed to check whether an item exist in the dynamo. if it does, it needs to generate the presigned url, otherwise it has to update the dynamodb item.
When it matches the item, it works as expected where as it fails when dynamo getitem output is null fails with states.runtime error. It does not going through catch statement. appreciate any help.
Here is my code.
{ "Comment": "A Hello World example of the Amazon States Language using Pass states", "StartAt": "Hello", "States": {
"Hello": {
"Type": "Pass",
"Next": "Verify item from DynamoDB"

solved this using choice state. Open to hear any suggestions on Catch state.

I'm setting up an action which uses push notifications. Yet, on firebase I can't get "UPDATES_USER_ID" of user to save. It returns "undefined".
I followed the guide on this link and here is my code to get UPDATES_USER_ID.
app.intent('Setup', (conv, params) => {
conv.ask(new UpdatePermission({
intent: "notificationResponseIntent"
}));
});
app.intent("FinishNotificationSetup", (conv, params) => {
if (conv.arguments.get('PERMISSION')) {
conv.data.GoogleUserID = conv.arguments.get("UPDATES_USER_ID");
console.log(conv.data.GoogleUserID);
conv.ask("some response....");
}
});
And here is my webhook request when FinishNotificationSetup intent is invoked.

To send notification, I've been using userID instead of UPDATES_USER_ID and it is working. Yet, it will be deprecated soon. So, I need to find a solution to get this ID and couldn't make it working. What do I need to do to get this ID?
I've found solution for this problem. While getting UPDATES_USER_ID conv.arguments.get() only works for first attempt. So, while building your action you must save it. If you didn't store or save, you can reset your profile and try again, you will be able to get.
app.intent("FinishNotificationSetup", (conv, params) => {
if (conv.arguments.get('PERMISSION')) {
if(!conv.user.storage.GoogleUserID)
{
conv.user.storage.GoogleUserID = conv.arguments.get("UPDATES_USER_ID");
//For best case
//store ID in your db.
}
console.log(conv.user.storage.GoogleUserID);
conv.ask("some response....");
}
});
For best case, try saving this to your database because conv.user.storage does not work sometimes.
I hope I can express myself a way you can all understand.
Here's the thing, I'm developing a back-end for an app in nodeJS. There's a table named 'chat' in dynamoDB with the ID of the chat's creator and a list of messages IDs, also there's a table named 'messages' with the author of each message and the text.
When the front-end asks the server for all the chats it has to send a list of chats objects with this sctructure:
[
{
"ID_CHAT": {
"S": "asd123asd"
},
"author": {
"name": "Name",
"lastname": "Lastname"
},
"date": {
"S": "19/11/2017 16:00"
},
"USER_DESTINATION": {
"S": "222asd222"
},
"messages": [
{
"Item": {
"author": {
"name": "Name",
"lastname": "Lastname"
},
"text": {
"S": "Hi!"
},
"MESSAGE_ID": {
"S": "456asd456"
},
"date": {
"S": "19/11/2017 16:05"
}
}
},
{
"Item": {
"author": {
"name": "Name",
"lastname": "Lastname"
},
"text": {
"S": "zup?"
},
"MESSAGE_ID": {
"S": "789asd789"
},
"date": {
"S": "19/11/2017 16:06"
}
}
}
]
}
{
"ID_CHAT": {
"S": "123asd123asd"
},
"author": {
"S": "123asd123"
}, and so on...
]
But in order to send this I need to get the chat's authors data from dynamodb (asynchronous function) and the list of messages data again from dynamodb.
I tried combining map() to get the chats authors and Promise.all() for the messages but it won't work cause the second iteration of the map() function runs after the Promise.then().
I'll appretiate your help!
Hi I have a Consumer test produced using Pact NPM https://www.npmjs.com/package/pact
I use the following code to generate a pact.json:
provider
.addInteraction({
state: 'test',
uponReceiving: 'a test,
withRequest: {
method: 'GET',
path: '/test'
},
willRespondWith: {
status: 200,
headers: { 'Content-Type': 'application/json' }
body: {
"company": like("My big company"),
"factories": eachLike({
"location": like("Sydney"),
"capacity": like(5)
},{min:1})
}
}
})
.then(function(){ done(); });
It generates the following testconsumer-testprovider.json file:
{
"consumer": {
"name": "TestConsumer"
},
"provider": {
"name": "TestProvider"
},
"interactions": [
{
"description": "a request for loans",
"providerState": "broker is logged in, list all loans",
"request": {
"method": "GET",
"path": "/test"
},
"response": {
"status": 200,
"headers": {
"Content-Type": "application/vnd.hal+json"
},
"body": {
"company": "My big company",
"factories": [
{
"location": "Sydney",
"capacity": 5
}
]
},
"matchingRules": {
"$.headers.Content-Type": {
"match": "regex",
"regex": "application\\/.*json.*"
},
"$.body.company": {
"match": "type"
},
"$.body.factories": {
"min": 1
},
"$.body.factories[*].*": {
"match": "type"
},
"$.body.factories[*].location": {
"match": "type"
},
"$.body.factories[*].capacity": {
"match": "type"
}
}
}
}
],
"metadata": {
"pactSpecification": {
"version": "3.0.0"
}
}
}
However when we test against the following provided output we get an error with the geographicCoords because it's an unexpected key/value:
{
"company": "My Company",
"factories": [
{
"location": "Sydney",
"capacity": 5
},
{
"location": "Sydney",
"geographicCoords": "-0.145,1.4445",
"capacity": 5,
}
]
}
So is there a was to allow unexpected key/values in arrays because we're only test for required key/values and we don't want out pact tests to fail in future when new values are added to our providers.
The scenario you are describing is supported, see https://github.com/pact-foundation/pact-js/tree/master/examples/e2e for an example.
If you were to remove, say the eligibility object and run the tests everything still works.
If you are still having troubles, please raise a defect on the pact-js repository and we'll get to the bottom of it.
