Incorrectly selected data in the query - graphql

Only articles that contain the EmailMarketing tag are needed.
I'm probably doing the wrong search on the tag, since it's an array of values, not a single object, but I don't know how to do it right, I'm just learning graphql. Any help would be appreciated
query:
query {
enArticles {
title
previewText
tags(where: {name: "EmailMarketing"}){
name
}
}
}
result:
{
"data": {
"enArticles": [
{
"title": "title1",
"previewText": "previewText1",
"tags": [
{
"name": "EmailMarketing"
},
{
"name": "Personalization"
},
{
"name": "Advertising_campaign"
}
]
},
{
"title": "title2",
"previewText": "previewText2",
"tags": [
{
"name": "Marketing_strategy"
},
{
"name": "Marketing"
},
{
"name": "Marketing_campaign"
}
]
},
{
"title": "article 12",
"previewText": "article12",
"tags": []
}
]
}
}

I believe you first need to have coded an equality operator within your GraphQL schema. There's a good explanation of that here.
Once you add an equality operator - say, for example _eq - you can use it something like this:
query {
enArticles {
title
previewText
tags(where: {name: {_eq: "EmailMarketing"}}){
name
}
}
}
Specifically, you would need to create a filter and resolver.
The example here may help.

Get GraphQL output without second curly bracket

I have a problem. I do not want a "break" down in my GraphQL output. I have a GraphQL schema with a person. That person can have one or more interests. But unfortunately I only get a breakdown
What I mean by breakdown is the second curly brackets.
{
...
{
...
}
}
Is there an option to get the id of the person plus the id of the interests and the status without the second curly bracket?
GraphQL schema
Person
└── Interest
Query
query {
model {
allPersons{
id
name
interest {
id
status
}
}
}
}
[OUT]
{
"data": {
"model": {
"allPersons": [
{
"id": "01",
"name": "Max",
"interest ": {
"id": 4488448
"status": "active"
}
},
{
"id": "02",
"name": "Sophie",
"interest ": {
"id": 15445
"status": "deactivated"
}
},
What I want
{
{
"id": "01",
"id-interest": 4488448
"status": "active"
},
{
"id": "02",
"name": "Sophie",
"id-interest": 15445
"status": "deactivated"
},
}
What I tried but that deliver me the same result
fragment InterestTask on Interest {
id
status
}
query {
model {
allPersons{
id
interest {
...InterestTask
}
}
}
}

How to use JSONpath to extract specific values

I'm using JSONpath to try and find data with an array of JSON objects but I'm struggling to get to the information I want. The array contains many objects similar to below where there are values for RecID throughout. If I use $..RecID I get them all when I only want the first Key.RecID of each object (with a value 1338438 in this example). Is there a way to only extract the top level Key.RecID value?
BTW I'm trying to do this in jMeter and I'm assuming JSONpath is the best way to do what I want but if there is a better way I'd be happy to hear about it.
Thanks in advance

Spring Mongo - An aggregation to order by objects in an array

I have the following data:
{
"_id": ObjectID("5e2fa881c3a1a70006c5743c"),
"name": "Some name",
"policies": [
{
"cId": "dasefa-2738-4cf0-90e0d568",
"weight": 12
},
{
"cId": "c640ad67dasd0-92f981583568",
"weight": 50
}
]
}
I'm able to query this with Spring Mongo fine, however I want to be able to order the policies by weight
At the moment I get my results fine with:
return mongoTemplate.find(query, CArea::class.java)
However say I make the following aggregations:
val unwind = Aggregation.unwind("policies")
val sort = Aggregation.sort(Sort.Direction.DESC,"policies.weight")
How can I go and actually apply those to the returned results above? I was hoping that the dot annotation would do the job in my query however didnt do anything e.g. Query().with(Sort.by(options.sortDirection, "policies.weight"))
Any help appreciated.
Thanks.
I am not familier with Spring Mongo, but I guess you can convert the following aggregation to spring code.
db.collection.aggregate([
{
$unwind: "$policies"
},
{
$sort: {
"policies.weight": -1
}
},
{
$group: {
_id: "$_id",
"policies": {
"$push": "$policies"
},
parentFields: {
$first: "$$ROOT"
}
}
},
{
$replaceRoot: {
newRoot: {
$mergeObjects: [
"$parentFields",
{
policies: "$policies"
}
]
}
}
}
])
This will result:
[
{
"_id": "5e2fa881c3a1a70006c5743c",
"name": "Some name",
"policies": [
{
"cId": "c640ad67dasd0-92f981583568",
"weight": 50
},
{
"cId": "dasefa-2738-4cf0-90e0d568",
"weight": 12
}
]
}
]

DynamoDB DocumentClient returns Set of strings (SS) attribute as an object

I'm new to DynamoDB.
When I read data from the table with AWS.DynamoDB.DocumentClient class, the query works but I get the result in the wrong format.
Query:
{
TableName: "users",
ExpressionAttributeValues: {
":param": event.pathParameters.cityId,
":date": moment().tz("Europe/London").format()
},
FilterExpression: ":date <= endDate",
KeyConditionExpression: "cityId = :param"
}
Expected:
{
"user": "boris",
"phones": ["+23xxxxx999", "+23xxxxx777"]
}
Actual:
{
"user": "boris",
"phones": {
"type": "String",
"values": ["+23xxxxx999", "+23xxxxx777"],
"wrapperName": "Set"
}
}
Thanks!
The [unmarshall] function from the [AWS.DynamoDB.Converter] is one solution if your data comes as e.g:
{
"Attributes": {
"last_names": {
"S": "UPDATED last name"
},
"names": {
"S": "I am the name"
},
"vehicles": {
"NS": [
"877",
"9801",
"104"
]
},
"updatedAt": {
"S": "2018-10-19T01:55:15.240Z"
},
"createdAt": {
"S": "2018-10-17T11:49:34.822Z"
}
}
}
Please notice the object/map {} spec per attribute, holding the attr type.
Means you are using the [dynamodb]class and not the [DynamoDB.DocumentClient].
The [unmarshall] will Convert a DynamoDB record into a JavaScript object.
Stated and backed by AWS. Ref. https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB/Converter.html#unmarshall-property
Nonetheless, I faced the exact same use case, as yours. Having one only attribute, TYPE SET (NS) in my case, and I had to manually do it. Next a snippet:
// Please notice the <setName>, which represents your set attribute name
ddbTransHandler.update(params).promise().then((value) =>{
value.Attributes[<setName>] = value.Attributes[<setName>].values;
return value; // or value.Attributes
});

How to filter GraphQL results by a descendent without edges?

I just started looking at GraphQL and I am wondering if there is a way to filter results that don't have any nodes. Here is a relatively simple example query:
query {
organization(login:"GitHub") {
repositories(first: 20) {
edges {
node {
name
pullRequests(first: 5, states: OPEN){
edges {
node {
title
author{
login
}
updatedAt
}
}
}
}
}
}
}
}
and here is a subset of the results that query returns:
{
"data": {
"organization": {
"repositories": {
"edges": [
{
"node": {
"name": "gitignore",
"pullRequests": {
"edges": [
{
"node": {
"title": "Create new CodeComposerStudio.gitignore",
"author": {
"login": "wolf99"
},
"updatedAt": "2017-07-26T20:31:53Z"
}
},
{
"node": {
"title": "Create PVS.gitignore",
"author": {
"login": "cesaramh"
},
"updatedAt": "2017-05-01T19:42:07Z"
}
},
{
"node": {
"title": "gitignore for Magic Software Enterprises product xpa ",
"author": {
"login": "tommes"
},
"updatedAt": "2017-05-01T19:41:53Z"
}
},
{
"node": {
"title": "Create PSoC.gitignore",
"author": {
"login": "dbrwn"
},
"updatedAt": "2017-05-01T19:41:39Z"
}
},
{
"node": {
"title": "add ThinkPHP gitignore file",
"author": {
"login": "swumao"
},
"updatedAt": "2017-05-01T19:40:53Z"
}
}
]
}
}
},
{
"node": {
"name": "dmca",
"pullRequests": {
"edges": []
}
}
}
]
}
}
}
}
So I'd like to know if there is a way to modify my query so that it would not return the node named dmca since there are no edges on pullRequests.
If you are using githubs graphql api than it seems that there is no way to filter those edges,
But if you're implementing the graphql server then it's possible to know what the edges nodes are and thus filter it in the edge resolver
According to GitHub repositories documentation does not allow that kind of filtering.
first: Int
Returns the first n elements from the list.
after: String
Returns the elements in the list that come after the specified cursor.
last: Int
Returns the last n elements from the list.
before: String
Returns the elements in the list that come before the specified cursor.
privacy: RepositoryPrivacy
If non-null, filters repositories according to privacy
orderBy: RepositoryOrder
Ordering options for repositories returned from the connection
affiliations: [RepositoryAffiliation]
Affiliation options for repositories returned from the connection
isLocked: Boolean
If non-null, filters repositories according to whether they have been locked
isFork: Boolean
If non-null, filters repositories according to whether they are forks of another repository
So I don't think that can be done.
