I would like to insert more than one record using GraphQL Mutation but it is giving error. here is the code which I have used to perform this.
input BusinessImageInput {
business_id: Int
image_url: String
}
mutation MyMutation($images: [BusinessImageInput!]) {
insert_business_images(objects: [$images]) {
affected_rows
}
}
And here is variable which i want to pass as paramter.
{"images": [
{
"business_id": 15,
"image_url": "https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcTVzlb1cEw8E0LeLJzk9c0OQV-N387Nt2Kn5w&usqp=CAU"
},
{
"business_id": 15,
"image_url": "https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcTVzlb1cEw8E0LeLJzk9c0OQV-N387Nt2Kn5w&usqp=CAU"
}
]
}
Here is the error
{
"errors": [
{
"extensions": {
"path": "$.query",
"code": "bad-request"
},
"message": "not a valid GraphQL query"
}
]
}
Please help me out.
There is one glaring issue in your code. This line
insert_business_images(objects: [$images]) {
should be
insert_business_images(objects: $images) {
Notice the removed square brackets.
If that does not help, then we'll need more information, such as:
what error do you get?
which implementation of GraphQL are you using both client-side and server-side?
what does the GraphQL code (and possibly resolvers) look like on the server? You have only given us the client-side of the equation.
It's as simple as
mutation MyMutation($images: [BusinessImageInput!]) {
insert_business_images(images: $images) {
or
mutation MyMutation($objects: [BusinessImageInput!]) {
insert_business_images(objects: $objects) {
depends on server insert_business_images mutation definition, the name of argument (images or objects ?) - use explorer ... and [as you can see above] usually input arg and variable are same-named, they only differs with $ prefix.
https://graphql.org/learn/queries/#variables
Also you must follow server input types.

I am new to GraphQL and creating a API Server using Flask and GraphQL,
Facing some issues while handling the "where" clause in GraphQL Request.
The basic Request and Response is working fine . please find a short snippet of the Schema I have designed
type data {
edges:[data_edges]
}
type QueryCustom {
data: data
}
type Query {
query: QueryCustom
}
Below mentioned basic request (Without the where clause) is working fine with this schema
query {
query {
data {
edges { .... }
But Getting an error when I am executing the Request with the where clause
query dataClosingSoon($month: Long) {
query{
data(where: { LastModifiedDate: { CALENDAR_MONTH: { value: { eq: $month } } } } ) {
edges { ....... }
Following is the response I get:
{
"errors": [
{
"locations": [
{
"column": 40,
"line": 1
}
],
"message": "Unknown type 'Long'."
},
{
"locations": [
{
"column": 9,
"line": 5
}
],
"message": "Unknown argument 'where' on field 'QueryCustom.data'."
}
]
}
I need to understand how to handle the where condition.
GraphQL is not SQL. You cannot use SQL clauses such as WHERE, LIKE, etc. in a GraphQL query.
You need to look at the schema to check how can you filter your query. These filters are pre-defined in the schema. You cannot create custom filters (at least in a basic sense) for a GraphQL query.
Edit:
If you want to use the query you are trying to send, your schema should look like something this:
type data {
edges:[data_edges]
}
type Query {
data(where: Filter!): data
}
input type Filter {
lastModifiedDate: // the type of this field
// Rest of the input fields
}
Note that your first query and the second query are totally different. Your second query is clearly wrong due to two reasons:
The Query type does not have a field called data. It only has one field called query. (I wouldn't add a field named query under the Query type though).
Your data field does not have any inputs. But your document (the GraphQL request) clearly does.
I'm very new to GraphQL, and i'm trying to perform some example queries to this graph. In particular i'm trying the User schema.
According to that documentation, the schema is the following:
id: ID!
liquidityPositions: [LiquidityPosition!]
usdSwapped: BigDecimal!
And here is query i tried:
{
user (where: {id: "0x7c9C48b7cBEbBDA3268435F20c81f15A538C566C"}) {
id
liquidityPositions
usdSwapped
}
}
This query fails, i keep getting the following response:
{
"errors": [
{
"locations": [
{
"line": 0,
"column": 0
}
],
"message": "No value provided for required argument: `id`"
}
]
}
How can i provide the id field and where am i supposed to provide it? Thanks in advance!
You've got a couple of problems with that query. First, to get a user by id, remove the "where" and curly braces from your query. Secondly, the liquityPositions field needs a selection of subfields. Like so:
{
user (id: "0x7c9C48b7cBEbBDA3268435F20c81f15A538C566C") {
id
liquidityPositions {
id
}
usdSwapped
}
}
That website you linked to will show you errors with your query so you can interactively learn more about what is supported.
I would also suggest running through the introduction to GraphQL here: https://graphql.org/learn/ to get a handle on how things are done.
My Apollo Server have following definition.
input MinMax{
min:Float
max:Float
}
input ScreenerInput{
fy:Int!
quarter:Int!
ltp:MinMax
eps:MinMax
pe:MinMax
netWorth:MinMax
paidUp:MinMax
reserve:MinMax
netProfit:MinMax
}
How can I define MinMax type in Apollo client to send variables for the MinMax type. Till now I was doing scalar types only so my query were simple.
My query type is screeenedCompanies(criteria:ScreenerInput!):[ScreenedCompanies]
if I query directly like below it works.
{
screeenedCompanies(criteria:{
fy:2075
quarter:2
eps:{
min:30
max:40
}
}){
sector
symbol
}
}
What I want is to query like this so that variables can be changed
query getScreenedCompanies($criteria:<What type should be here ?>){
{
screeenedCompanies(criteria:$criteria){
sector
symbol
}
}
}
After giving ScreenerInput as type my query looks like below
query getScreenedCompanies($criteria:ScreenerInput!){
screeenedCompanies(criteria:$criteria){
sector
symbol
}
}
my variables in apolloplayground look like below
{
"criteria": {
"fy": 2075
"quarter": 4
"ltp": {
"min": 345
"max": 400
}
}
}
I am receiving the following error
"error": {
"errors": [
{
"message": "Variable \"$criteria\" of required type \"ScreenerInput!\" was not provided."
It works the same way, as any scalar type in GQL. Just define them with the same input name as on the server(like MinMax or ScreenerInput in your case). You don't need to describe its shape on the client, server will validate it for you :)
And don't forget to add exclamation mark !, if parameter is required.
I am new to GraphQL and I wonder how I can explore an API without a possible wildcard (*) (https://github.com/graphql/graphql-spec/issues/127).
I am currently setting up a headless Craft CMS with GraphQL and I don't really know how my data is nested.
Event with the REST API I have no chance of just getting all the data, because I have to setup all the endpoints and therefore I have to know all field names as well.
So how could I easily explore my CraftCMS data structure?
Thanks for any hints on this.
Cheers
merc
------ Edit -------
If I use #simonpedro s suggestion:
{
__schema {
types {
name
kind
fields {
name
}
}
}
}
I can see a lot of types (?)/fields (?)...
For example I see:
{
"name": "FlexibleContentTeaser",
"kind": "OBJECT",
"fields": [
{
"name": "id"
},
{
"name": "enabled"
},
{
"name": "teaserTitle"
},
{
"name": "text"
},
{
"name": "teaserLink"
},
{
"name": "teaserLinkConnection"
}
]
But now I would like to know how a teaserLink ist structured.
I somehow found out that the teaserLink (it is a field with the type Entries, where I can link to another page) has the properties url & title.
But how would I set up query to explore the properties available within teaserLink?
I tried all sorts of queries, but I am always confrontend with messages like this:
I would be really glad if somebody could give me another pointer how I can find out which properties I can actually query...
Thank you
As far as I'm concerned currently there is no graphql implementation with that capability. However, if what you want to do is to explore the "data structure", i.e, the schema, you should use schema instrospection, which was thought for that (explore the graphql schema). For example, a simple graphql instrospection query would be like this:
{
__schema {
types {
name
kind
fields {
name
}
}
}
}
References:
- https://graphql.org/learn/introspection/
UPDATE for edit:
What you want to do I think is the following:
Make a query like this
{
__schema {
types {
name
kind
fields {
name
type {
fields {
name
}
}
}
}
}
}
And then find the wished type field to grab more information (the fields) from it. Something like this (I don't know if this works, just an idea):
const typeFlexibleContentTeaser = data.__schema.types.find(t => t === "FlexibleContentTeaser")
const teaserLinkField = typeFlexibleContentTeaser.fields.find(f => f.name === "teaserLink")
const teaserLinkField = teaserLinkField.type.fields;
i.e, you have to transverse recursively through the type field.
I'm looking into GraphQL and got to a question I'm not even sure how to look for in the docs. Probably this isn't even supposed to work, but I'll ask anyway.
I have this query:
query {
organization(login: "facebook") {
repositories(first: 5) {
items: edges {
repo: node {
name
owner {
login
}
}
}
}
}
}
Now, in the response I would like a way to place the login next to name, instead of nested in owner login.
So in the response instead of:
{
...
"name": "react-native",
"owner": {
"login": "facebook"
}
}
I would like to have:
{
...
"name": "react-native",
"ownerName": "facebook"
}
Thank you.
From the specification this is not possible. The response has to be shaped in the way the object types are shaped. There is a project called GraphQL Lodash that gives you a new directive to modify the results. It can be helpful here but it is rather experimental and IMO very undogmatic.
