I'm using the Graphiql Go GUI. I'm trying to create mutation that creates a user. However, I get an error saying that an email has not been provided.
If I view the request, it doesn't include the substituted value. And because of that it doesn't ever make it far enough in the server to create a user.
I'm wondering the proper syntax for this. I've read the docs and several responses from the community and this looks to be the correct syntax.
mutation CreateUser($email: String!) {
createUser(email: $email) {
id
email
}
}
query variables:
{
"email": "test#test.com"
}
type:
var RootMutation = graphql.NewObject(graphql.ObjectConfig{
Name: "RootMutation",
Fields: graphql.Fields{
"createUser": &graphql.Field{
Type: UserType,
Description: "Creates a new user",
Args: graphql.FieldConfigArgument{
"email": &graphql.ArgumentConfig{
Type: graphql.NewNonNull(graphql.String),
},
},
Resolve: func(params graphql.ResolveParams) (interface{}, error) {
email, err := params.Args["email"].(string)
log.Println(err)
log.Println(email)
// handle creating user
},
},
},
})
Error:
{
"data": null,
"errors": [
{
"message": "Variable \"$email\" of required type \"String!\" was not provided.",
"locations": [
{
"line": 1,
"column": 21
}
]
}
]
}
I don't understand why if there are no errors on the client GUI side (graphiql) why it wouldn't be sending along the email to the backend.
Is there something I'm missing?

Here's what I'm trying to accomplish:
I have a graphql API endpoint that returns me a Project object like this(unrelated fields removed):
{
"data": {
"Project": {
"id": "cjp4b84wkochq0167gpu8oa7h",
"requests": [
{
"id": "cjpbb6jcdpwj00167y4acl5a1",
"__typename": "Request"
},
{
"id": "cjpbbhlaxpwlx01675jzfyb0j",
"__typename": "Request"
},
{
"id": "cjpbbifg7pwmg0167s0ob1bm6",
"__typename": "Request"
},
],
"__typename": "Project"
}
}
}
I want to use apollo-link-state to add a client-side field to all of these Request objects like this:
{
"data": {
"Project": {
"id": "cjp4b84wkochq0167gpu8oa7h",
"requests": [
{
"id": "cjpbb6jcdpwj00167y4acl5a1",
"expanded": false,
"__typename": "Request"
},
{
"id": "cjpbbhlaxpwlx01675jzfyb0j",
"expanded": false,
"__typename": "Request"
},
{
"id": "cjpbbifg7pwmg0167s0ob1bm6",
"expanded": false,
"__typename": "Request"
},
],
"__typename": "Project"
}
}
}
This would allow me to remove local state from my Component that renders these requests. The problem is that when I define defaults for my ApolloClient clientState as follows:
const client = new ApolloClient({
clientState: {
defaults: {
Project: {
__typename: 'Project',
requests: [{ __typename: 'Request', expanded: false }],
},
},
},
});
Apollo adds it as a new Project object instead of adding it to the existing one(which has an id):
ROOT_QUERY
Project: Project
requests: [Request]
0:
expanded: false
Project({"id":"cjp4b84wkochq0167gpu8oa7h"}): Project
▾Project:cjp4b84wkochq0167gpu8oa7h
when I give it the id it adds the "hi" field to the correct project but the requests are still missing the expanded field. And giving the id only works for a specific project obviously.
const client = new ApolloClient({
clientState: {
defaults: {
'Project({"id":"cjp4b84wkochq0167gpu8oa7h"})': {
__typename: 'Project',
hi: true,
requests: [{ __typename: 'Request', expanded: false }],
},
},
},
});
ROOT_QUERY
Project({"id":"cjp4b84wkochq0167gpu8oa7h"}): Project
▾Project:cjp4b84wkochq0167gpu8oa7h
hi: true
requests: [Request]
0:▾Request:cjpbb6jcdpwj00167y4acl5a1
...unrelated fields
1:▾Request:cjpbbhlaxpwlx01675jzfyb0j
2:▾Request:cjpbbifg7pwmg0167s0ob1bm6
I also tried using the typeDefs field on the clientState object like this:
typeDefs: [`
schema {
query: RootQuery
}
type RootQuery {
Project($id: ID): Project
}
type Project {
id: ID!
requests: [Request]
}
type Request {
id: ID!
expanded: Boolean
}
`],
but this doesn't seem to change anything on the cache and I don't know if I can even give it a default value like this.
Maybe I'm misunderstanding how apollo-link-state works (or even how graphql works) any answer to point me in the right direction is appreciated. I'm very much a beginner when it comes to graphql or apollo.
You need to provide a client side resolver to your clientState configuration.
const clientState = {
resolvers: {
Project {
expanded: () => false
}
}
}
And then you'd pass this into your ApolloClient like so
const apolloClient = new ApolloClient({ clientState });
I'm new to all graphql world, so this might be a very easy question, sorry
I'm using graphql-compose-mongoose to generate my graphql schema, here's my mongoose schema:
const ComplainSchema = new Schema({
entityId: {type: String, required: true},
user: {type: UserInfoSchema, required: true},
title: String, // standard types
desc: String,
state: {required: true, type: String, enum: ["DRAFT", "MODERATION", "PUBLIC", "SOLVED"]},
attachments: [{
url: {type: String, required: true},
name: String,
mimeType: String,
attachmentId: Schema.Types.ObjectId
}],
createdAt: {type: Date, index: true},
updatedAt: {type: Date, index: true},
}, {timestamps: {}})
export default mongoose.model('Complaint', ComplainSchema)
If I attempt the following mutation in graphiql it works fine
mutation {
complaintUpdateById(record:{_id:"5bdd9350fe144227042e6a20", title:"ok", desc:"updated", attachments:[{name:"zied", url:"http://zied.com"}]}){
recordId,
record{
_id,
entityId,
user {
userId,
userName,
roleInShop
},
title,
desc,
createdAt,
updatedAt,
attachments{
name,
url
}
}
}
}
and returns this (in case there could be helpful to see the response)
{
"data": {
"complaintUpdateById": {
"recordId": "5bdd9350fe144227042e6a20",
"record": {
"_id": "5bdd9350fe144227042e6a20",
"entityId": "5bd9b1858788f51f44ab678a",
"user": {
"userId": "5bd9ac078788f51f44ab6785",
"userName": "Zied Hamdi",
"roleInShop": "ASA"
},
"title": "ok",
"desc": "updated",
"createdAt": "2018-11-03T12:23:44.565Z",
"updatedAt": "2018-11-05T09:02:51.494Z",
"attachments": [
{
"name": "zied",
"url": "http://zied.com"
}
]
}
}
}
}
Now if I try to pass the attachments to apollo, I don't know how to do that, I don't know which type to provide (Attachment is not the right type obvisouly):
const UPDATE_COMPLAINT = gql `mutation complaintUpdateById($_id:MongoID!, $title: String!, $desc: String!, $attachments: [Attachment]
)
{
complaintUpdateById(record:{_id:$_id, title:$title, desc:$desc, attachments:$attachments}){
recordId,
record{
_id,
entityId,
user {
userId,
userName,
roleInShop
},
title,
desc,
createdAt,
updatedAt
}
}
}`
So searching for the right type, I did a introspection of my object, the issue is that I get the type of attachment as null for this query:
{
__type(name: "Complaint") {
kind
name
fields {
name
description
type {
name
}
}
}
}
this is the response:
{
"data": {
"__type": {
"kind": "OBJECT",
"name": "Complaint",
"fields": [
{
"name": "entityId",
"description": null,
"type": {
"name": "String"
}
},
{
"name": "user",
"description": null,
"type": {
"name": "ComplaintUser"
}
},
{
"name": "title",
"description": null,
"type": {
"name": "String"
}
},
{
"name": "desc",
"description": null,
"type": {
"name": "String"
}
},
{
"name": "state",
"description": null,
"type": {
"name": "EnumComplaintState"
}
},
{
"name": "attachments",
"description": null,
"type": {
"name": null
}
},
{
"name": "createdAt",
"description": null,
"type": {
"name": "Date"
}
},
{
"name": "updatedAt",
"description": null,
"type": {
"name": "Date"
}
},
{
"name": "_id",
"description": null,
"type": {
"name": null
}
}
]
}
}
}
googling didn't help since I don't know how is this operation called, I don't think it's a nested mutation from what I found...
Ok fixed,
I did these steps:
I first introspected the type of attachment in a regular query using the __typename keyword: as follows
mutation {
complaintUpdateById(record:{_id:"5bdd9350fe144227042e6a20", title:"ok", desc:"updated", attachments:[{name:"zied", url:"http://zied.com"}]}){
recordId,
record{
_id,
entityId,
user {
userId,
userName,
roleInShop
},
title,
desc,
createdAt,
updatedAt,
attachments{
__typename,
name,
url
}
}
}
}
it showed up a type named ComplaintAttachments
when replacing the Attachment type with this new value, ComplaintAttachments, an error occured and that error message helped me out:
Variable "$attachments" of type "[ComplaintAttachments]" used in
position expecting type "[ComplaintComplaintAttachmentsInput]"
so the array is of type ComplaintComplaintAttachmentsInput, I still don't know how to introspect it directly, but I'm already happy with the result :)
I'm using the Go implemenatation of GraphQL.
How would you configure a mutation so that it can receive arguments with more than 1 level?
For exemple, here is the list of arguments I would like to pass to a mutation CreateUser:
mutation createUser($user: CreateUser!) {
createUser(input: $user)
}
{
"user": {
"name": {
"first": "John",
"last": "Doe"
},
"email": "john#doe.com"
}
}
(Notice that I dont want to use firstname and lastname but a name object instead)
And this is my (unsuccessful) attempt so far:
var CreateUserInput = graphql.FieldConfigArgument{
"input": &graphql.ArgumentConfig{
Description: "Input for creating a new user",
Type: graphql.NewNonNull(graphql.NewInputObject(graphql.InputObjectConfig{
Name: "CreateUser",
Fields: graphql.InputObjectConfigFieldMap{
"name": &graphql.InputObjectFieldConfig{
Type: graphql.NewNonNull(graphql.NewInputObject(graphql.InputObjectConfig{
Fields: graphql.InputObjectConfigFieldMap{
"first": &graphql.InputObjectFieldConfig{
Type: graphql.NewNonNull(graphql.String),
},
"last": &graphql.InputObjectFieldConfig{
Type: graphql.NewNonNull(graphql.String),
},
},
})),
},
"email": &graphql.InputObjectFieldConfig{
Type: graphql.NewNonNull(graphql.String),
},
},
})),
},
}
Apparently the subfields first and last are not recognized as this is what I get when I run this mutation:
{
"data": null,
"errors": [
{
"message": "Variable \"$user\" got invalid value {\"email\":\"john#doe.com\",\"name\":{\"first\":\"john\",\"last\":\"doe\"}}.\nIn field \"name\": In field \"first\": Unknown field.\nIn field \"name\": In field \"last\": Unknown field.",
"locations": [
{
"line": 1,
"column": 21
}
]
}
]
}
Is this even possible?
EDIT: See comments in the accepted answer for the solution.
This are my first ever lines of Go but I will try to convey what I think the problem is.
First lets talk about the structure you want to be going for. I will use SDL here:
type Mutation {
createUser(user: CreateUser!): Boolean! # Maybe return user type here?
}
input CreateUser {
name: CreateUserName!
email: String!
}
input CreateUserName {
first: String!
last: String!
}
Okay now that we know that we need two input types lets get started!
var CreateUserName = graphql.NewInputObject(graphql.InputObjectConfig{
Name: "CreateUserName",
Fields: graphql.InputObjectConfigFieldMap{
"first": &graphql.InputObjectFieldConfig{
Type: graphql.NewNonNull(graphql.String),
},
"last": &graphql.InputObjectFieldConfig{
Type: graphql.NewNonNull(graphql.String),
},
},
})
var CreateUser = graphql.NewInputObject(graphql.InputObjectConfig{
Name: "CreateUser",
Fields: graphql.InputObjectConfigFieldMap{
"name": &graphql.InputObjectFieldConfig{
Type: graphql.NewNonNull(CreateUserName),
},
"email": &graphql.InputObjectFieldConfig{
Type: graphql.NewNonNull(graphql.String),
},
},
})
Now all that should be left is adding the mutation field to your mutation object type.
I have this GraphQL type:
type User {
id: String
name: String
}
defined by
var UserObject = graphql.NewObject(graphql.ObjectConfig{
Name: "User",
Fields: graphql.Fields{
"id": &graphql.Field{
Type: graphql.String,
},
"name": &graphql.Field{
Type: graphql.String,
},
},
})
In my root query, I want to link some users with the query field users:
var RootQuery = graphql.NewObject(graphql.ObjectConfig{
Name: "RootQuery",
Fields: graphql.Fields{
"users": &graphql.Field{
Type: graphql.NewList(UserObject),
Resolve: func(p graphql.ResolveParams) (interface{}, error) {
return Users{
User{
ID: "1",
NAME: "John",
},
User{
ID: "2",
NAME: "Jess"
}
}, nil
},
},
},
})
type User struct {
ID string
NAME string
}
type Users []User
As you see, I have a User and Users data types. So far, so good.
Now, imagine I can't create the User nor Users structs, what could I return in Resolve function instead of them?
I thought about a []map[string]string. It would be something like this:
var RootQuery = graphql.NewObject(graphql.ObjectConfig{
Name: "RootQuery",
Fields: graphql.Fields{
"users": &graphql.Field{
Type: graphql.NewList(UserObject),
Resolve: func(p graphql.ResolveParams) (interface{}, error) {
users := []map[string]string {
map[string]string {
"id" : "1",
"name" : "John",
},
map[string]string {
"id" : "2",
"name" : "Jess",
},
}
return users, nil
},
},
},
})
But it doesn't work. Every property is nil in the query result. Is there a way to solve this? Remember I can't create the User struct. This has to be "generic".
You can use map[string]interface{} instead of map[string]string and it should work. Why that is? I don't really know, I couldn't find any docs as to what's acceptable as the return value from FieldResolveFn.
users := []map[string]interface{}{{
"id": "1",
"name": "John",
}, {
"id": "2",
"name": "Jess",
}}
return users, nil
On a fresh sailsjs installation, I've got a test model defined like this:
module.exports = {
attributes: {
username:{
type:'string'
}
,email:{
type:'string'
,email:true
}
}
};
And if I navigate to this:
http://localhost:1337/user/create?username=stratboy1&email=test#wow.com
I get this error:
{
"error": "E_VALIDATION",
"status": 400,
"summary": "1 attribute is invalid",
"model": "User",
"invalidAttributes": {
"email": [
{
"rule": "email",
"message": "\"email\" validation rule failed for input: 'test#wow.com'"
}
]
}
}
Any of you knows why?
I've come across this earlier but don't quite remember the cause.
As a quick fix, you can substitute
email: { type: 'string', email: true }
with
email: { type: 'email' }
