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,

I'm trying to filter Directus CMS data set through URL parameters.
This is a sample data set. I can successfully filter data set by single parameter.
{
"data":[
{
"id": "1",
"status": "published",
"category": "Novel",
"section": "Kids"
},
{
"id": "2",
"status": "published",
"category": "Novel",
"section": "Adults"
}
]
}
/items/books?filter[category][_eq]=Novel
gives me exactly what I expected which is 1 & 2 data records.
But I need to filter both "category" & "section" fields
/items/books?filter[category][_eq]=Novel&filter[section][_eq]=Adults
For above I receive an empty data set.
Why is this getting failed ? Where do I need to fix? Appreciate your support in advance. Thanks!
Try the following query:
/items/books?filter={"_or":[{"category":{"_eq": "Novel"}},{"section":{"_eq":"Adults"}}]}
An expanded version of the filter:
"_or": [
{
"category": {
"_eq": "Novel"
}
},
{
"section": {
"_eq": "Adults"
}
}
]

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 :)

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.
Knowing the schema (fetched via getIntrospectionQuery), how could I get the type of a particular field?
For example, say I run this query:
query {
User {
name
lastUpdated
friends {
name
}
}
}
and get this result:
{
"data": {
"User": [
{
"name": "alice",
"lastUpdated": "2018-02-03T17:22:49+00:00",
"friends": []
},
{
"name": "bob",
"lastUpdated": "2017-09-01T17:08:49+00:00",
"friends": [
{
"name": "eve"
}
]
}
]
}
}
I'd like to know the types of the fields and construct something like this:
{
"name": "String",
"lastUpdated": "timestamptz",
"friends": "[Friend]"
}
How could I do that without extra requests to the server?
After retrieving the schema, you can build it into a JSON object (if your graphql framework does not do it already for you).
Using a JSON parser, you can retrieve the the types of each field.
I will not enter into the detail, as it would depend on the technology your are using.
I'm relatively new to ES and am having difficulty finding really good references or tutorials on the query dsl.
We have a document type of the example below. The query I wish to conduct is thus: "Return all the email_package records that have at least one entities record (one record in the 'entities' array)." And yes I want the complete 'email' record.
Could anyone assist? Also if you could point to a reference or tutorial or cookbook somewhere that addresses question like this, that would be also greatly appreciated.
"email_package": {
"email": {
"date": "2007-02-13T18:24:22-04:00",
"subject": "this is the subject",
"body": "this is the body"
},
"entities": [
{
"Louisville": {
"City": "South"
}
},
{
"Memphis": {
"City": "South"
}
}
]
}
// more 'email_package records follow...
Your document is a bit problematic, since you seems to be nesting objects and giving them different names. If you are not bound to the current structure, I would have changed the mapping into something that is more manageable, and queries will be straight forward, e.g:
"email_package": {
"email": {
"body": "this is the body1",
"date": "2007-02-13T18:24:22-04:00",
"subject": "this is the subject"
},
"entities": [
{
"name": "Louisville"
"City": "South",
},
{
"name": "Memphis"
"City": "South",
}
]
}
Query:
{ "filter": {
"exists": {
"field": "email_package.entities.name"
}
}
