I have a function is js that return an JSON array
[
{
"coordinates": {
"lat": 1,
"lng": 2
},
"name": "33301 - Fort Lauderdale, Florida"
},
{
"coordinates": {
"lat": 3,
"lng": 4
},
"name": "33301 - Atlanta, Georgia"
}
]
How do I write a Chai expect statement to check for a name value...
Basically, I want to see if the result name parameter contain "33301 - Atlanta, Georgia"
Thanks for your help
You can filter out the data and validate:
//filter your data by name
const filteredData=myObject.filter(object=>object.name==='33301 - Atlanta, Georgia');
// now you can check the length of that filtered array
expect(filteredData).to.have.length(1);

I am writing a GraphQL resolver that retrieves all vertices by a particular edge using the following query (created returns label person):
software {
created {
name
}
}
Which would resolve to the following Gremlin Query for each software node found:
g.V().hasLabel('software').has('name', 'ripple').in('created')
This returns a result that includes all properties of the object:
{
"result": [
{
"#type": "d",
"#rid": "#24:0",
"#version": 6,
"#class": "person",
"in_knows": [
"#35:0"
],
"name": "josh",
"out_created": [
"#32:0",
"#33:0"
],
"age": 32,
"#fieldTypes": "in_knows=g,out_created=g"
}
],
"dbStats": {
...
}
}
I realize that this will fall foul on GraphQL's N+1 query so i'm trying to batch queries together using a Dataloader pattern. (i'm also hoping to do property selections, so i'm not asking the database to return too much info)
So i'm trying to craft a query like so:
g.V().union(
__.hasLabel('software').has('name', 'ripple').
project('parent', 'child').by('id').
by(__.in('created').fold()),
__.hasLabel('software').has('name', 'lop').
project('parent', 'child').by('id').
by(__.in('created').fold())
)
But this results in the following where the props are missing and it just includes the id of the vertices I want:
{
"result": [
{
"parent": "ripple",
"child": [
"#24:0"
]
},
{
"parent": "lop",
"child": [
"#22:0",
"#23:0",
"#24:0"
]
}
],
"dbStats": {
...
}
}
My Question is, how can I have the Gremlin query return all of the props for the found vertices and none of the other props? Should I even been doing batching this way?
For anyone else reading, the query I was trying to write wouldn't work because the TraversalSet created in the .by(_.in('created') can't be cast from a List to an ElementMap as the stream cardinality wouldn't be enforced. (You can only have one record per row, I think?)
My working query would be to duplicate the keys for each row and specify the props needed (the query below is ok for gremlin 3.3 as used in ODB, otherwise if you've got < gremlin 3.4 replace the last by step with be(elementMap('name', 'age')):
g.V().union(
__.hasLabel('software').has('name', 'ripple').
as('parent').
in('created').as('child').
select('parent', 'child').
by(values('name')).
by(properties('id', 'name', 'age').
group().by(__.key()).
by(__.value())),
__.hasLabel('software').has('name', 'lop').
as('parent').
in('created').as('child').
select('parent', 'child').
by(values('name')).
by(properties('id', 'name', 'age').
group().by(__.key()).
by(__.value()))
)
So that you get a result like this:
{"data": [
{
"parent": "ripple",
"child": {
"id": 5717,
"name": "josh",
"age": 32
}
},
{
"parent": "lop",
"child": {
"id": 5709,
"name": "peter",
"age": 35
}
},
{
"parent": "lop",
"child": {
"id": 5713,
"name": "marko",
"age": 29
}
},
{
"parent": "lop",
"child": {
"id": 5717,
"name": "josh",
"age": 32
}
}
]
}
Which would allow you to create a lookup where you concat all results for "lop" and "ripple" into arrays.
need some suggestion for a dataweave 2 transformation that can transform the following input (Array of Object having an id field) to the following output (grouping in an array the objects sharing the same id into a map, having the id as key).
Input :
[
{
"id": "1117",
"Tot": "10.0",
"Per": "7/2025"
},
{
"id": "1117",
"Tot": "200.0",
"Per": "2/2021"
},
{
"id": "7997",
"Tot": "78.0",
"Per": "10/2023"
}
]
output
{
"1117": [
{
"id": "1117",
"Tot": "10.0",
"Per": "7/2025"
},
{
"id": "1117",
"Tot": "200.0",
"Per": "2/2021"
}
],
"7997": [
{
"id": "7997",
"Tot": "78.0",
"Per": "10/2023"
}
]
}
Any idea?
Thanks

payload groupBy $.id
You just want to group by the ID? There ya go.
I would recommend going to https://developer.mulesoft.com/learn/dataweave and then going to the tutorial tab (top right). It will walk through these basic scenarios :)

I am quite new to graphQL, and after searching the whole afternoon, i didn't found my answer to a relative quite simple problem.
I have two objects in my strapi backend :
"travels": [
{
"id": "1",
"title": "Bolivia: La Paz y Salar de Uyuni",
"travel_types": [
{
"name": "Culturales"
},
{
"name": "Aventura"
},
{
"name": "Ecoturismo"
}
]
},
{
"id": "2",
"title": "Europa clásica 2020",
"travel_types": [
{
"name": "Clasicas"
},
{
"name": "Culturales"
}
]
}
]
I am trying to get a filter where I search for travels containing ALL the user-selected travel_types.
I then wrote a query like that :
query($where: JSON){
travels (where:$where) {
id # Or _id if you are using MongoDB
title
travel_types {name}
}
And the parameter i try to input for testing :
{
"where":{
"travel_types.name_contains": ["Aventura"],
"travel_types.name_contains": ["Clasicas"]
}
}
This should return an empty array, because none of the travels have both Aventura and Clasicas travel-types.
But instead it returns the travel with id=2. It seems that only the second filter is taken.
I searched for a query which would be like Array.every() in javascript, but i wasn't able to find.
Does someone has an idea how to achieve this type of filtering ?
Thank you very much,
When I execute following graphQL query which has only one function and I get output which is shown below.
I want output which has largest ID or the latest timestamp.
It is possible by making change in API but my constraint is not to make any change in API and have enhance the query only, Please help me how can I achieve my goal/ desired output
Input
query getAllCriticalevent{
getAllCriticalevent(patientId: 95)
{
id
startTime
}
}
Output
{
"data": {
"getAllCriticalevent": [
{
"id": "107",
"startTime": "2019-06-14 12:47:57.0"
},
{
"id": "1464",
"startTime": "2019-10-10 16:08:35.0"
},
{
"id": "1465",
"startTime": "2019-10-10 16:09:09.0"
},
{
"id": "1466",
"startTime": "2019-10-10 16:09:44.0"
},
{
"id": "1469",
"startTime": "2019-10-10 16:11:28.0"
},
{
"id": "1470",
"startTime": "2019-10-10 16:12:03.0"
},
{
"id": "1484",
"startTime": "2019-10-10 16:20:09.0"
}
]
}
}
My expected output is this
{
"startTime": "2019-10-10 16:20:09.0"
}
or
{
"id": "1484",
"startTime": "2019-10-10 16:20:09.0"
}
One way to do this is to add a column to the Type definition, then return it from your resolver.
In Laravel (not Java), the definition:
'max' => [
'type' => Type::int(),
'description' => 'The highest score achieved'
],
and a separate query in the ORM resolver (getMaxAttribute() is referenced as simply .max()):
public function getMaxAttribute() {
return DB::table('players')->max('score');
}
will return the max for a desired column. You request the column by name in GraphQL, just like normal (eg. "{ ... max }").
I am trying to retrieve data from the weather.gov API - it returns the format in geoJSON and I am not sure how to actually get the data I want from it.
If I am using the weatherbit.io API, I have no issues as it returns JSON format in which I can pull from rather easily.
I am using GuzzleHTTP to make the API call.
I am playing around with learning APIs and I have an interest in weather so I figured I would work on an application in which I could pull information from the local weather station and output it in to readable format for users in a table.
The code I am currently using is:
$api_call = https://api.weather.xxx/points/LAT,LON;
$client = new \GuzzleHttp\Client();
$request = $client->get($api_call);
if ($request->getStatusCode() == 200) {
$weatherRequest = $request->getBody();
$requestedWeather = json_decode($weatherRequest);
$currentweather = $requestedWeather; ** THIS IS WHERE I NEED HELP ***
}
return $currentweather;
});
return view('currentweather', ["currentweather" => $currentweather]);
When I am returning $currentweather and var_dump it to the view, it gives me all the geoJSON data but I don't know how to correctly iterate through the data to pull the information I need.
When I pull from another API it gives a different JSON format which I can just pull like so:
$api_call = https://api.weatherbit.xx/v2.0/current?
$client = new \GuzzleHttp\Client();
$request = $client->get($api_call);
if ($request->getStatusCode() == 200) {
$weatherRequest = $request->getBody();
$requestedWeather = json_decode($weatherRequest);
$currentweather = $requestedWeather->data;
}
return $currentweather;
});
return view('currentweather', ["currentweather" => $currentweather]);
}
And when I use $currentweather in my view I can pull any data I need with the object string name. I am not sure how to pull the data when it's leading off with the #Context tag.
The data I want lies in the "properties" part of the geoJSON array and I just can't seem to figure out how to get that in the way I am currently using.
This is my geoJSON array return:
{ "#context": [ "https://raw.githubusercontent.xxx/geojson/geojson-ld/master/contexts/geojson-base.jsonld", { "wx": "https://api.weather.xxx/ontology#", "s": "https://schema.org/", "geo": "http://www.opengis.xxx/ont/geosparql#", "unit": "http://codes.wmo.xxx/common/unit/", "#vocab": "https://api.weather.xxx/ontology#", "geometry":

Thanks for your help!
Any member of the JSON object can be accessed via the same name on the object returned by json_decode. Your weatherbit example $requestedWeather->data works because everything is in a member called data. So... $requestedWeather->properties will get you what you want from the weather.gov API.
You can also pass true as a second argument to json_decode to get back a plain PHP array instead.
$requestedWeather = json_decode($weatherRequest, true);
var_dump($requestedWeather['properties']);
This is often recommended because JSON allows member names that are not valid PHP object property names (e.g., names containing hyphens).
