I have a custom controller to replace a default querie named "groupedOrders"
but when I try to test the query the response is
"message": "Cannot read property 'user' of undefined",
the code in api/grouped-order/controllers/grouped-order.js is:
module.exports = {
byUser: async ctx => {
const user = ctx.state.user
const resTypeUser = await strapi.query('tipo-usuario').find({ _id: user.tipo_usuario })
var resGroupedOrder = { error: true }
if (resTypeUser[0].super_admin) {
resGroupedOrder = await strapi.query('grouped-order').find()
} else if (resTypeUser[0].cliente) {
resGroupedOrder = await strapi.query('grouped-order').find({ users_permissions_user: user._id })
}
return resGroupedOrder
}
};
and the code in api/grouped-order/config/schema.graphql.js is:
module.exports = {
definition: ``,
query: ``,
type: {},
resolver: {
Query: {
groupedOrders: {
description: "Retornar todos los pedidos dependiendo el tipo de usuario",
resolverOf: "application::grouped-order.grouped-order.byUser",
policies: [
'plugins::users-permissions.permissions',
],
resolver: async (obj, options, ctx) => {
return await strapi.controllers["grouped-order"].byUser(ctx);
}
}
},
},
}
the test that I try to run in http://localhost:1337/graphql is:
query groupedOrders($where:JSON){
groupedOrders(where:$where){
createdAt
detail
status
}
}
and the HTTP HEADERS:
{
"Authorization": "Bearer TOKENJWT"
}
Solved, I just add this code on my controller:
if (!ctx.state && ctx.request && ctx.request.header && ctx.request.header.authorization) {
const { id } = await strapi.plugins["users-permissions"].services.jwt.getToken(ctx);
ctx.state.user = await strapi.plugins['users-permissions'].services.user.fetchAuthenticatedUser(id);
}
we can add the code globally, like this: https://github.com/strapi/strapi/issues/9159#issuecomment-789484109

as per the title, I am having problem trying to enable graphql subscription in my loopback 4 application.
Here is my code that I've done so far.
index.ts
export async function main(options: ApplicationConfig = {}) {
const app = new BackendLb4Application(options)
await app.boot()
await app.start()
const url = app.restServer.url;
const oas: Oas3 = <Oas3><unknown>await app.restServer.getApiSpec()
const {schema} = await createGraphQLSchema(oas, {
operationIdFieldNames: true,
baseUrl: url,
createSubscriptionsFromCallbacks: true,
})
const handler = graphqlHTTP( (request:any, response:any, graphQLParams: any) => ({
schema,
pretty: true,
graphiql: true
}))
app.mountExpressRouter(graphqlPath, handler);
const pubsub = new PubSub()
const ws = createServer(app);
ws.listen(PORT, () => {
new SubscriptionServer(
{
execute,
subscribe,
schema,
onConnect: (params: any, socket: any, ctx: any) => {
console.log(params, 'here on onconnect')
// Add pubsub to context to be used by GraphQL subscribe field
return { pubsub }
}
},
{
server: ws,
path: '/subscriptions'
}
)
})
return app
}
Here is my schema
type Subscription {
"""
Equivalent to PATCH onNotificationUpdate
"""
postRequestQueryCallbackUrlApiNotification(secondInputInput: SecondInputInput): String
"""
Equivalent to PATCH onNotificationUpdate
"""
postRequestQueryCallbackUrlOnNotificationUpdate(firstInputInput: FirstInputInput): String
}
Here is an example of my controller
#patch('/notification-update', {
operationId: 'notificationUpdate',
description: '**GraphQL notificationUpdate**',
callbacks:[ {
onNotificationUpdate: {
//'{$request.query.callbackUrl}/onNotificationUpdate': {
post: {
requestBody: {
operationId: 'notificationUpdateCallback',
description: 'rasjad',
content: {
'application/json': {
schema: {
title: "firstInput",
type: 'object',
properties: {
userData: {
type: "string"
}
}
}
}
}
},
responses: {
'200': {
description: 'response to subscription',
}
}
}
},
// }
}],
responses: {
'200': {
description: 'Notification PATCH success count',
content: {'application/json': {schema: CountSchema}},
},
},
})
async updateAll(
#requestBody({
content: {
'application/json': {
schema: getModelSchemaRef(Notification, {partial: true}),
},
},
})
notification: Notification,
#param.where(Notification) where?: Where<Notification>,
): Promise<Count> {
return this.notificationRepository.update(notification, where);
}
Ive defined the callbacks object in my controller which will then create a subscription in my schema. Tested it out on graphiql but did not work.
I am not sure where to go from here. Do I need a custom resolver or something? Not sure.
Appreciate it if anyone could help on this.
Just in case someone else is looking to do the same thing.
I switched out graphqlHTTP with Apollo Server to create my graphql server.
So my final index.ts looks like this.
export async function main(options: ApplicationConfig = {}) {
const lb4Application = new BackendLb4Application(options)
await lb4Application.boot()
await lb4Application.migrateSchema()
await lb4Application.start()
const url = lb4Application.restServer.url;
const graphqlPath = '/graphql'
// Get the OpenApiSpec
const oas: Oas3 = <Oas3><unknown>await lb4Application.restServer.getApiSpec()
// Create GraphQl Schema from OpenApiSpec
const {schema} = await createGraphQLSchema(oas, {
strict: false,
viewer: true,
baseUrl: url,
headers: {
'X-Origin': 'GraphQL'
},
createSubscriptionsFromCallbacks: true,
customResolvers: {
"lb4-title": {
"your-path":{
patch: (obj, args, context, info) => {
const num = Math.floor(Math.random() * 10);
pubsub.publish("something", { yourMethodName: {count: num} }).catch((err: any) => {
console.log(err)
})
return {count: 1}
}
}
}
},
customSubscriptionResolvers: {
"lb4-title" : {
"yourMethodName": {
post: {
subscribe: () => pubsub.asyncIterator("something"),
resolve: (obj: any, args: any, context, info) => {
console.log(obj, 'obj')
}
}
}
}
}
})
const app = express();
const server = new ApolloServer({
schema,
plugins: [{
async serverWillStart() {
return {
async drainServer() {
subscriptionServers.close();
}
};
}
}],
})
const subscriptionServers = SubscriptionServer.create(
{
// This is the `schema` we just created.
schema,
// These are imported from `graphql`.
execute,
subscribe,
},
{
server: lb4Application.restServer.httpServer?.server,
path: server.graphqlPath,
//path: server.graphqlPath,
}
);
await server.start();
server.applyMiddleware({ app, path: "/" });
lb4Application.mountExpressRouter('/graphql', app);
return lb4Application
}
Also you will need to define the callbacks object in your controller like so.
#patch('/something-update', {
operationId: 'somethingUpdate',
description: '**GraphQL somethingUpdate**',
callbacks:[
{
yourMethodName: {
post: {
responses: {
'200': {
description: 'response to subscription',
content: {'application/json': {schema: CountSchema}},
}
}
}
},
}
],
responses: {
'200': {
description: 'Something PATCH success count',
content: {'application/json': {schema: CountSchema}},
},
},
})
async updateAll(
#requestBody({
content: {
'application/json': {
schema: getModelSchemaRef(Something, {partial: true}),
},
},
})
something: Something,
#param.where(Something) where?: Where<Something>,
): Promise<Count> {
return this.somethingRepository.updateAll(something, where);
}
And that is it. You can test it out from the GraphQL Playground and play around with the subscriptions.
For the time being, I am fine with defining customResolvers and customSubscriptionResolvers but I'm pretty sure I can automate this two objects from the controllers.
Cheers!
Is it possible to add logic in resolvers using GraphQL mutations?
I am trying to create a four-digit string as an alias for a post if the user does not provide it. Then, I would like to check the database to see if the four-digit string exists. If the string exists, I would like to create another four-digit string recursively.
At the moment, I'm exploring adding logic to mutations within resolvers, but I'm not sure if this is doable. I'm using these documents for my foundation: graphql.org sequelize.org
This is my current code block:
Working as of 12/4/2020
const MakeSlug = require("./services/MakeSlug");
const resolvers = {
Query: {
async allLinks(root, args, { models }) {
return models.Link.findAll();
},
async link(root, { id }, { models }) {
return models.Link.findByPk(id);
}
},
Mutation: {
async createLink(root, { slug, description, link }, { models }) {
if (slug !== undefined) {
const foundSlug = await models.Link.findOne({
where: { slug: slug }
});
if (foundSlug === undefined) {
return await models.Link.create({
slug,
description,
link,
shortLink: `https://shink.com/${slug}`
});
} else {
throw new Error(slug + " exists. Try a new short description.");
}
}
if (slug === undefined) {
const MAX_ATTEMPTS = 10;
let attempts = 0;
while (attempts < MAX_ATTEMPTS) {
attempts++;
let madeSlug = MakeSlug(4);
const foundSlug = await models.Link.findOne({
where: { slug: madeSlug }
});
if (foundSlug !== undefined) {
return await models.Link.create({
slug: madeSlug,
description,
link,
shortLink: `https://shink.com/${madeSlug}`
});
}
}
throw new Error("Unable to generate unique alias.");
}
}
}
};
module.exports = resolvers;
This is my full codebase.
Thank you!
A while loop solved the challenge. Thanks xadm.
const MakeSlug = require("./services/MakeSlug");
const resolvers = {
Query: {
async allLinks(root, args, { models }) {
return models.Link.findAll();
},
async link(root, { id }, { models }) {
return models.Link.findByPk(id);
}
},
Mutation: {
async createLink(root, { slug, description, link }, { models }) {
if (slug !== undefined) {
const foundSlug = await models.Link.findOne({
where: { slug: slug }
});
if (foundSlug === undefined) {
return await models.Link.create({

module.exports = resolvers;
I have the following GRAPHQL subscription:
Schema.graphql
type Subscription {
booking: SubscriptionData
}
type SubscriptionData {
booking: Booking!
action: String
}
And this is the resolver subsrciption file
Resolver/Subscription.js
const Subscription = {
booking: {
subscribe(parent, args, { pubsub }, info) {
return pubsub.asyncIterator("booking");
}
}
};
export default Subscription;
Then I have the following code on the Mutation in question
pubsub.publish("booking", { booking: { booking }, action: "test" });
I have the follow subscription file in front end (React)
const getAllBookings = gql`
query {
bookings {
time
durationMin
payed
selected
activity {
name
}
}
}
`;
const getAllBookingsInitial = {
query: gql`
query {
bookings {
time
durationMin
payed
selected
activity {
name
}
}
}
`
};
class AllBookings extends Component {
state = { allBookings: [] }
componentWillMount() {
console.log('componentWillMount inside AllBookings.js')
client.query(getAllBookingsInitial).then(res => this.setState({ allBookings: res.data.bookings })).catch(err => console.log("an error occurred: ", err));
}
componentDidMount() {
console.log(this.props.getAllBookingsQuery)
this.createBookingsSubscription = this.props.getAllBookingsQuery.subscribeToMore(
{
document: gql`
subscription {
booking {
booking {
time
durationMin
payed
selected
activity {
name
}
}
action
}
}
`,
updateQuery: async (prevState, { subscriptionData }) => {
console.log('subscriptionData', subscriptionData)
const newBooking = subscriptionData.data.booking.booking;
const newState = [...this.state.allBookings, newBooking]
this.setState((prevState) => ({ allBookings: [...prevState.allBookings, newBooking] }))
this.props.setAllBookings(newState);
}
},
err => console.error(err)
);
}
render() {
return null;
}
}
export default graphql(getAllBookings, { name: "getAllBookingsQuery" })(
AllBookings
);
And I get the following response:
data: {
booking: {booking: {...} action: null}}
I get that I am probably setting up the subscription wrong somehow but I don't see the issue.
Based on your schema, the desired data returned should look like this:
{
"booking": {
"booking": {
...
},
"action": "test"
}
}
The first booking is the field on Subscription, while the second booking is the field on SubscriptionData. The object you pass to publish should have this same shape (i.e. it should always include the root-level subscription field).
pubsub.publish('booking', {
booking: {
booking,
action: 'test',
},
})
I have written integration tests for graphql-js subscriptions, which are showing weird behavior.
My graphq-js subscription works perfectly in GraphiQL. But when the same subscriptions is called from unit test, it fails.
Ggraphql-Js object, with resolve function and subscribe function
return {
type: outputType,
args: {
input: {type: new GraphQLNonNull(inputType)},
},
resolve(payload, args, context, info) {
const clientSubscriptionId = (payload) ? payload.subscriptionId : null;
const object = (payload) ? payload.object : null;
var where = null;
var type = null;
var target = null;
if (object) {
where = (payload) ? payload.object.where : null;
type = (payload) ? payload.object.type : null;
target = (payload) ? payload.object.target : null;
}
return Promise.resolve(subscribeAndGetPayload(payload, args, context, info))
.then(payload => ({
clientSubscriptionId, where, type, target, object: payload.data,
}));
},
subscribe: withFilter(
() => pubSub.asyncIterator(modelName),
(payload, variables, context, info) => {
const subscriptionPayload = {
clientSubscriptionId: variables.input.clientSubscriptionId,
remove: variables.input.remove,
create: variables.input.create,
update: variables.input.update,
opts: variables.input.options,
};
subscriptionPayload.model = model;
try {
pubSub.subscribe(info.fieldName, null, subscriptionPayload);
} catch (ex) {
console.log(ex);
}
return true;
}
),
};
Subscription query
subscription {
Customer(input: {create: true, clientSubscriptionId: 112}) {
customer {
id
name
age
}
}
}
Mutation query
mutation {
Customer {
CustomerCreate (input:{data:{name:"Atif 50", age:50}}) {
obj {
id
name
}
}
}
}

expect(await subscriptionPromise).to.deep.equal({});
});
});
Issue Here
When test in run, payload in the resolve function contains global data, where as it should contain the subscription payload. So the code breaks.
I have simple mutation with variables as:
Mutation Query
mutation M($name: String) {
Adduser(name: $name) {
_id
name
}
}
Query variables
{
"name":"user1"
}
And in graphql API:
app.post('/graphql', (req, res) => {
const query = req.body.query;
const vars = req.body.variables;
//console.log(vars);/*showing { "name":"user1" }*/
graphql(Schema, query, null, vars).then(result => {
res.send(result);
});
});
but the output i am getting is:
{
"data": {
"Adduser": {
"_id": "593a2cd4cf057a07d073e971",
"name": null
}
}
}
Updated
userType:
const Adduser = {
type: userType,
args: {
name: {
type: graphql.GraphQLString
},
age: {
type: graphql.GraphQLInt
}
},
resolve: (obj, args) => {
return new Promise((resolve, reject) => {
var user=new User({
name:args.name
});
user.save(function(err,usr){
if(err){
console.log(err);
}
else{
resolve(usr);
}
});
})
}
};
mutation:
const Rootmutation = new graphql.GraphQLObjectType({
name: 'Rootmutation',
fields: {
Adduser: Adduser
}
});
const schema = new graphql.GraphQLSchema({
query: Rootquery,
mutation: Rootmutation
});
It means the variable value is not binding with mutation query.
Any suggestion here??
