Is it possible to get an article(single entity) using the Url Alias (entityUrl.path)?
I am using https://github.com/drupal-graphql/graphql
I can do a bulk query for all the articles, do I then filter those results?
Thanks
query GetArticles {
nodeQuery(filter: {conditions: [{field: "type", value: "article"}]}) {
Articles: entities {
entityId
entityLabel
entityUrl {
path
routed
}
}
}
}
Figured it out
query ($path: String!) {
route:route(path: $path) {
... on EntityCanonicalUrl {
entity {
... on Node {
nid
entityLabel
body{
value
}
}
}
}
}
}

I need to get a query using graphql in strapi/gatsby where id is {id}.
According to the documentation found here you query all like so:
{
allStrapiArticle {
edges {
node {
id
title
content
}
}
}
}
This works and I'm able to query however I'd like to get only one Article where id is {id};
I have tried:
{
allStrapiArticle(id: "4") {
edges {
node {
id
title
content
}
}
}
}
And also:
{
allStrapiArticle {
edges {
node(id: "4") {
id
title
content
}
}
}
}
Both of the above give me an error. Any idea how I can achieve this?
Use:
{
allStrapiArticle(filter: {id: {eq: "4" }}) {
edges {
node {
id
title
content
}
}
}
}
elemMatch filter might be useful for your use case as well.
Check the localhost:8000/___graphql playground to test your queries and filters.

I have the following GraphQL query; "categories" is a one-to-many relationship, each containing a name and a slug. I want to get all Articles with category slug of "derp". Any thoughts?
{
allContentfulArticle(
sort: { order: DESC, fields: [createdAt] }
) {
edges {
node {
title
slug
datePublished
createdAt
categories {
name
slug
}
}
}
}
}
Contentful DevRel here. 👋
I just prototyped your scenario and this query should do it.
query {
categoryCollection(where: { slug_contains: "schnitzel" }) {
items {
linkedFrom {
entryCollection {
items {
...on Article {
title
}
}
}
}
}
}
}
You can find more info in the docs about links to a specific entry.
Hope that helps. :)
I'm having trouble understanding how to write filters for GraphQL queries in GatsbyJS.
This works:
filter: { contentType: { in: ["post", "page"] }
I basically need the reverse of that, like:
filter: { "post" in: { contentTypes } } // where contentTypes is array
That doesn't work because "NAME is expected" (where "post" is in my example).
After going through GatsbyJS docs I found this:
elemMatch: short for element match, this indicates that the field you are filtering will return an array of elements, on which you can apply a filter using the previous operators
filter:{
packageJson:{
dependencies:{
elemMatch:{
name:{
eq:"chokidar"
}
}
}
}
}
Great! That's what I need! So I try that, and I get:
error GraphQL Error Field "elemMatch" is not defined by type markdownRemarkConnectionFrontmatterTagsQueryList_2.
Keywords defined in markdownRemarkConnectionFrontmatterTagsQueryList_2 are:
eq: string | null;
ne: string | null;
regex: string | null;
glob: string | null;
in: Array | null;
Why am I limited to these keywords when more keywords such as elemMatch are mentioned in docs? Why am I not allowed to use the filter structure "element in: { array }"?
How can I create this filter?
Filter by value in an array
Let's say you have a markdown blog with categories as an array of string, you can filter posts with "historical" in categories like this:
{
allMarkdownRemark(filter:{
frontmatter:{
categories: {
in: ["historical"]
}
}
}) {
edges {
node {
id
frontmatter {
categories
}
}
}
}
}
You can try this query out in any of the graphiq blocks in Gatsby.js docs.
ElemMatch
I think elemMatch is only 'turned on' for fields with array of objects; something like comments: [{ id: "1", content: "" }, { id: "2", content: ""}]. This way, you can apply further filters on the fields of each comment:
comments: { elemMatch: { id: { eq: "1" } } }
Here's an example you can try out in the graphiq blocks in gatsby docs:
// only show plugins which have "#babel/runtime" as a dependency
{
allSitePlugin (filter:{
packageJson:{
dependencies: {
elemMatch: {
name: {
eq: "#babel/runtime"
}
}
}
}
}) {
edges {
node {
name
version
packageJson {
dependencies {
name
}
}
}
}
}
}
I am running a graphQL server on Sangria (scala). Here is an example query:
query {
missions {
missionId { id } ,
name
}
}
and a sample response:
{
"data": {
"missions": [
{
"missionId": {
"id": "mission1"
},
"name": "foo"
},
{
"missionId": {
"id": "mission2"
},
"name": "bar"
}
]
}
}
I am looking for a query that filters the list and only returns the element having mission1 as id?
You need implement pagination. Pass limit(pageSize) argument to graphql server resolver. process the datas in server-side.
query {
missions(limit: 1) {
missionId { id } ,
name
}
}
server-side:
const resolvers = {
Query: {
missions: (_, {limit}, ctx) => {
const missions = [];
for(let i = 0; i < limit; i++) {
missions.push(db.missions[i])
}
return missions;
}
}
}
That's graphql ideology, front-end developer define the data structure and what data they want to get.
It's bad idea to query the list data through a http request. And filter the data in front-end using directive or other way of graphql. Waste bandwidth.
How to use more than one objects when querying Github GraphQL?
The following will break if the 2nd object is uncommented:
query {
repository(owner:"rails", name:"rails") {
object(expression:"master") {
... on Commit {
history {
totalCount
}
}
}
# object(expression: "master:README.md") {... on Blob {byteSize}}
}
}
How to make it working? Thx
Use alias:
query {
repository(owner:"rails", name:"rails") {
object(expression:"master") {
... on Commit {
history {
totalCount
}
}
},
second_object: object(expression: "master:README.md") {... on Blob {byteSize}}
}
}
