I'm very new to Strapi and GraphQL. I have created a nested data structure in Strapi that looks like this (this is a Navbar component). But when I go to GraphQL, my query looks like this.
So if this is the query:
query MyQuery {
allStrapiNavbar {
nodes {
Category {
Name
children {
id
}
}
}
}
}
This is the result:
{
"data": {
"allStrapiNavbar": {
"nodes": [
{
"Category": [
{
"Name": "Community",
"children": []
},
{
"Name": "Modules",
"children": []
},
{
"Name": "Company",
"children": []
},
{
"Name": "Pricing",
"children": []
}
]
}
]
}
},
"extensions": {}
}
This means the data is being fetched correctly. However, I can't find the nested component 'Item' inside 'Category'.
This is what my gatsby-config.ts file looks like currently:
{
resolve: "gatsby-source-strapi",
options: {
apiURL: process.env.STRAPI_API_URL || "http://localhost:1337",
queryLimit: 1000, // Default to 100
accessToken: process.env.STRAPI_TOKEN,
collectionTypes:[ 'faq', 'doc', 'docCategory', 'faqCategory', 'release', 'userType' ],
// contentTypes: [ 'Faq' ],
singleTypes: [ 'navbar' ],
},
I don't know why the data isn't showing up in GraphQL. I looked inside the children for Category, but the reality is that it should be at the same level as Name, which shows up.
Do I need to modify the gatsby-config file, or am I missing something else?
Edit: I am using the gatsby-source-strapi plugin.
I am actually new to this highcharts . Been trying to render a line chart . I am facing issues while transforming the data returned by back-end to the data required by highcharts.
Can someone suggest me how to transform the below data object to the data required by line charts.Trying to plot a graph that compares current and previous values
Help would be appreaciated.
Object
{"data":
[
{"currentVal":3488,"prevVal":0,"timestamp":1554181200000},
{"currentVal":3453,"prevVal":3,"timestamp":1554481200000},
{"currentVal":3456,"prevVal":2,"timestamp":1554581200000}
]
}
As per the documnentaion the line charts data accepts the following structure.
"data": [
{
"name": "currentVal",
"data": [ 7,7,8]
},
{
"name": "prevVal",
"data": [1,6,7]
}
]
}
I would want the help in transforming the object that mentioned in the top
The simplest way to transform the object:
var obj = {
data: [{
"currentVal": 3488,
"prevVal": 3000,
"timestamp": 1554181200000
}, {
"currentVal": 3453,
"prevVal": 3123,
"timestamp": 1554481200000
}, {
"currentVal": 3456,
"prevVal": 3341,
"timestamp": 1554581200000
}]
};
Highcharts.chart('container', {
xAxis: {
type: 'datetime'
},
series: [{
name: "currentVal",
data: obj.data.map(elem => [
elem.timestamp, elem.currentVal
])
}, {
name: "prevVal",
data: obj.data.map(elem => [
elem.timestamp, elem.prevVal
])
}]
});

I am performing an Axios get call in a React Component to retrieve JSON info. That function is working great. Within the JSON is a label for various network ports, which are returning as an array in my axios call. These are ultimately going to be displayed as nodes on a d3 graph. My issue is that I need to output the data pulled from the get call into the following format:
nodes: [
{ id: 'JSON data.label here' },
{ id: 'JSON data.label here' },
{ id: 'JSON data.label here' },
{ id: 'JSON data.label here' },
{ id: 'JSON data.label here' }
]
So the full component for the graph to read is:
export const data = {
nodes: [
{ id: 'JSON data.label here' },
{ id: 'JSON data.label here' },
{ id: 'JSON data.label here' },
{ id: 'JSON data.label here' },
{ id: 'JSON data.label here' }
]
}
Here is the format of the Axios get I am using:
axios.get(`NetworkConstruct.json`)
.then(res => {
const names = res.data.items;
this.setState({ names });
});
Here is a sample output I am receiving (there are 11 of these):
{id: "5bc0860c-ece1-461c-bac0-b155a3cacd82", label: "80.107.0.212",
resourceTypeId: "tosca.resourceTypes.NetworkConstruct", productId:
"5bc0835c-6cfa-486e-8429-a59eaf4118bc", tenantId: "393fa8da-61fd-458c-80f9-
ce92d0ef0330", …}
The data has to be in this EXACT format or the graph won't read it. I'm guessing I'll need to do an initial map function but am stuck on how to arrange it. I cannot have any divs or quotes in my output. Is this doable? I have scoured the boards and Google for a couple of days and can't make this work yet.
Here is the object I am receiving from the GET request.

The info I need is the nodes ID. There are eleven of them in the full object.
You can map an array of objects to another array of objects in your format with Array.prototype.map(). Assuming that data is the list of objects from your response:
class Graph extends React.Component {
state = {
nodes: null,
};
componentDidMount() {
axios.get('the url').then(response => {
const nodes = response.data.outputs.graph.nodes;
this.setState({nodes});
});
}
render() {
const {nodes} = this.state;
if (!nodes) return 'Loading...'
return <TheD3ComponentYouUse nodes={nodes} />;
}
}
I need to modify a document inside an array that is inside another array.
I know MongoDB doesn't support multiple '$' to iterate on multiple arrays at the same time, but they introduced arrayFilters for that.
See: https://jira.mongodb.org/browse/SERVER-831
MongoDB's sample code:
db.coll.update({}, {$set: {“a.$[i].c.$[j].d”: 2}}, {arrayFilters: [{“i.b”: 0}, {“j.d”: 0}]})
Input: {a: [{b: 0, c: [{d: 0}, {d: 1}]}, {b: 1, c: [{d: 0}, {d: 1}]}]}
Output: {a: [{b: 0, c: [{d: 2}, {d: 1}]}, {b: 1, c: [{d: 0}, {d: 1}]}]}
Here's how the documents are set:
{
"_id" : ObjectId("5a05a8b7e0ce3444f8ec5bd7"),
"name" : "support",
"contactTypes" : {
"nonWorkingHours" : [],
"workingHours" : []
},
"workingDays" : [],
"people" : [
{
"enabled" : true,
"level" : "1",
"name" : "Someone",
"_id" : ObjectId("5a05a8c3e0ce3444f8ec5bd8"),
"contacts" : [
{
"_id" : ObjectId("5a05a8dee0ce3444f8ec5bda"),
"retries" : "1",
"priority" : "1",
"type" : "email",
"data" : "some.email#email.com"
}
]
}
],
"__v" : 0
}
Here's the schema:
const ContactSchema = new Schema({
data: String,
type: String,
priority: String,
retries: String
});
const PersonSchema = new Schema({
name: String,
level: String,
priority: String,
enabled: Boolean,
contacts: [ContactSchema]
});
const GroupSchema = new Schema({
name: String,
people: [PersonSchema],
workingHours: { start: String, end: String },
workingDays: [Number],
contactTypes: { workingHours: [String], nonWorkingHours: [String] }
});
I need to update a contact. This is what I tried using arrayFilters:
Group.update(
{},
{'$set': {'people.$[i].contacts.$[j].data': 'new data'}},
{arrayFilters: [
{'i._id': mongoose.Types.ObjectId(req.params.personId)},
{'j._id': mongoose.Types.ObjectId(req.params.contactId)}]},
function(err, doc) {
if (err) {
res.status(500).send(err);
}
res.send(doc);
}
);
The document is never updated and I get this response:
{
"ok": 0,
"n": 0,
"nModified": 0
}
What am I doing wrong?
So the arrayFilters option with positional filtered $[<identifier>] does actually work properly with the development release series since MongoDB 3.5.12 and also in the current release candidates for the MongoDB 3.6 series, where this will actually be officially released. The only problem is of course is that the "drivers" in use have not actually caught up to this yet.
Re-iterating the same content I have already placed on Updating a Nested Array with MongoDB:
NOTE Somewhat ironically, since this is specified in the "options" argument for .update() and like methods, the syntax is generally compatible with all recent release driver versions.
However this is not true of the mongo shell, since the way the method is implemented there ( "ironically for backward compatibility" ) the arrayFilters argument is not recognized and removed by an internal method that parses the options in order to deliver "backward compatibility" with prior MongoDB server versions and a "legacy" .update() API call syntax.
So if you want to use the command in the mongo shell or other "shell based" products ( notably Robo 3T ) you need a latest version from either the development branch or production release as of 3.6 or greater.
All this means is that the current "driver" implementation of .update() actually "removes" the necessary arguments with the definition of arrayFilters. For NodeJS this will be addressed in the 3.x release series of the driver, and of course "mongoose" will then likely take some time after that release to implement it's own dependencies on the updated driver, which would then no longer "strip" such actions.
You can however still run this on a supported server instance, by dropping back to the basic "update command" syntax usage, since this bypassed the implemented driver method:
const mongoose = require('mongoose'),
Schema = mongoose.Schema,
ObjectId = mongoose.Types.ObjectId;
mongoose.Promise = global.Promise;
mongoose.set('debug',true);
const uri = 'mongodb://localhost/test',
options = { useMongoClient: true };
const contactSchema = new Schema({
data: String,
type: String,
priority: String,
retries: String
});
const personSchema = new Schema({
name: String,
level: String,
priority: String,
enabled: Boolean,
contacts: [contactSchema]
});
const groupSchema = new Schema({
name: String,
people: [personSchema],
workingHours: { start: String, end: String },
workingDays: { type: [Number], default: undefined },
contactTypes: {
workingHours: { type: [String], default: undefined },
contactTypes: { type: [String], default: undefined }
}
});
const Group = mongoose.model('Group', groupSchema);
function log(data) {
console.log(JSON.stringify(data, undefined, 2))
}
(async function() {
try {
const conn = await mongoose.connect(uri,options);
// Clean data
await Promise.all(
Object.entries(conn.models).map(([k,m]) => m.remove() )
);
// Create sample
await Group.create({
name: "support",
people: [
{
"_id": ObjectId("5a05a8c3e0ce3444f8ec5bd8"),
"enabled": true,
"level": "1",
"name": "Someone",
"contacts": [
{
"type": "email",
"data": "adifferent.email#example.com"
},
{
"_id": ObjectId("5a05a8dee0ce3444f8ec5bda"),
"retries": "1",
"priority": "1",
"type": "email",
"data": "some.email#example.com"
}
]
}
]
});
let result = await conn.db.command({
"update": Group.collection.name,
"updates": [
{
"q": {},
"u": { "$set": { "people.$[i].contacts.$[j].data": "new data" } },
"multi": true,
"arrayFilters": [
{ "i._id": ObjectId("5a05a8c3e0ce3444f8ec5bd8") },
{ "j._id": ObjectId("5a05a8dee0ce3444f8ec5bda") }
]
}
]
});
log(result);
let group = await Group.findOne();
log(group);
} catch(e) {
console.error(e);
} finally {
mongoose.disconnect();
}
})()
Since that sends the "command" directly through to the server, we see the expected update does in fact take place:
Mongoose: groups.remove({}, {})
Mongoose: groups.insert({ name: 'support', _id: ObjectId("5a06557fb568aa0ad793c5e4"), people: [ { _id: ObjectId("5a05a8c3e0ce3444f8ec5bd8"), enabled: true, level: '1', name: 'Someone', contacts: [ { type: 'email', data: 'adifferent.email#example.com', _id: ObjectId("5a06557fb568aa0ad793c5e5") }, { _id: ObjectId("5a05a8dee0ce3444f8ec5bda"), retries: '1', priority: '1', type: 'email', data: 'some.email#example.com' } ] } ], __v: 0 })
{ n: 1,
nModified: 1,
opTime:
{ ts: Timestamp { _bsontype: 'Timestamp', low_: 3, high_: 1510364543 },
t: 24 },
electionId: 7fffffff0000000000000018,
ok: 1,
operationTime: Timestamp { _bsontype: 'Timestamp', low_: 3, high_: 1510364543 },
'$clusterTime':
{ clusterTime: Timestamp { _bsontype: 'Timestamp', low_: 3, high_: 1510364543 },
signature: { hash: [Object], keyId: 0 } } }
Mongoose: groups.findOne({}, { fields: {} })
{
"_id": "5a06557fb568aa0ad793c5e4",
"name": "support",
"__v": 0,
"people": [
{
"_id": "5a05a8c3e0ce3444f8ec5bd8",
"enabled": true,
"level": "1",
"name": "Someone",
"contacts": [
{
"type": "email",
"data": "adifferent.email#example.com",
"_id": "5a06557fb568aa0ad793c5e5"
},
{
"_id": "5a05a8dee0ce3444f8ec5bda",
"retries": "1",
"priority": "1",
"type": "email",
"data": "new data" // <-- updated here
}
]
}
]
}
So right "now"[1] the drivers available "off the shelf" don't actually implement .update() or it's other implementing counterparts in a way that is compatible with actually passing through the necessary arrayFilters argument. So if you are "playing with" a development series or release candiate server, then you really should be prepared to be working with the "bleeding edge" and unreleased drivers as well.
But you can actually do this as demonstrated in any driver, in the correct form where the command being issued is not going to be altered.
[1] As of writing on November 11th 2017 there is no "official" release of MongoDB or the supported drivers that actually implement this. Production usage should be based on official releases of the server and supported drivers only.
I had a similar use case. But my second level nested array doesn't have a key. While most examples out there showcase an example with arrays having a key like this:
{
"id": 1,
"items": [
{
"name": "Product 1",
"colors": ["yellow", "blue", "black"]
}
]
}
My use case is like this, without the key:
{
"colors": [
["yellow"],
["blue"],
["black"]
]
}
I managed to use the arrayfilters by ommiting the label of the first level of the array nest. Example document:
db.createCollection('ProductFlow')
db.ProductFlow.insertOne(
{
"steps": [
[
{
"actionType": "dispatch",
"payload": {
"vehicle": {
"name": "Livestock Truck",
"type": "road",
"thirdParty": true
}
}
},
{
"actionType": "dispatch",
"payload": {
"vehicle": {
"name": "Airplane",
"type": "air",
"thirdParty": true
}
}
}
],
[
{
"actionType": "store",
"payload": {
"company": "Company A",
"is_supplier": false
}
}
],
[
{
"actionType": "sell",
"payload": {
"reseller": "Company B",
"is_supplier": false
}
}
]
]
}
)
In my case, I want to:
Find all documents that have any steps with payload.vehicle.thirdParty=true and actionType=dispatch
Update the actions set payload.vehicle.thirdParty=true only for the actions that have actionType=dispatch.
My first approach was withour arrayfilters. But it would create the property payload.vehicle.thirdParty=true inside the steps with actionType store and sell.
The final query that updated the properties only inside the steps with actionType=dispatch:
Mongo Shell:
db.ProductFlow.updateMany(
{"steps": {"$elemMatch": {"$elemMatch": {"payload.vehicle.thirdParty": true, "actionType": "dispatch"}}}},
{"$set": {"steps.$[].$[i].payload.vehicle.thirdParty": false}},
{"arrayFilters": [ { "i.actionType": "dispatch" } ], multi: true}
)
PyMongo:
query = {
"steps": {"$elemMatch": {"$elemMatch": {"payload.vehicle.thirdParty": True, "actionType": "dispatch"}}}
}
update_statement = {
"$set": {
"steps.$[].$[i].payload.vehicle.thirdParty": False
}
}
array_filters = [
{ "i.actionType": "dispatch" }
]
NOTE that I'm omitting the label on the first array at the update statement steps.$[].$[i].payload.vehicle.thirdParty. Most examples out there will use both labels because their objects have a key for the array. I took me some time to figure that out.
I try to setup a hasMany relationship and want load my main entity with all the associated models in a single request.
But that seems not to work with "hasMany" relations that is inherited.
I have a BaseModel that defines all relations and fields and a "normal" model that defines the proxy to load from.
These are my (relevant) models:
Ext.define('MyApp.model.BaseUser', {
"extend": "Ext.data.Model",
"uses": [
"MyApp.model.UserEmail",
"MyApp.model.Account"
],
"fields": [
{
"name": "name"
},
{
"name": "accountId",
"reference": {
"type": "MyApp.model.Account",
"role": "account",
"getterName": "getAccount",
"setterName": "setAccount",
"unique": true
}
}
]
"hasMany": [
{
"name": "emails",
"model": "MyApp.model.UserEmail"
}
],
});
Ext.define('MyApp.model.User', {
extend: "MyApp.model.BaseUser",
proxy: {
type: 'rest',
url : '/api/user',
reader: {
type: 'json',
rootProperty: 'data',
}
}
});
Ext.define('MyApp.model.UserEmail', {
extend: 'Ext.data.Model',
"fields": [
{
"name": "id",
"type": "int"
},
{
"name": "email",
"type": "string"
},
],
proxy: {
type: 'rest',
url : '/api/user/email',
reader: {
type: 'json',
rootProperty: 'data',
}
}
});
// MyApp.model.Account looks like MyApp.model.UserEmail
This is my server's response:
{
data: [
{
name: 'User Foo'
accountId: 50
account: {
id: 50,
balance: 0
},
emails: [
{
id: 70,
email: 'hello#world.de'
}
]
}
]
}
The "account" relation is working on the "normal" User Model and I can access it via the auto-generated method user.getAccount() as I expected.
Now I tried to access the users emails with the auto-generated methods:
// user is of 'MyApp.model.User'
user.emails(); // store
user.emails().first(); // null
user.emails().count(); // 0
It seems that the "emails"-relation models were not loaded into my user model. Am I accessing them the right way?
I can access them via user.data.emails. But this is an array of plain objects, not of UserEmail-Objects.
Can anyone give me some advice? Is nested loading supported with keyless associations?
Kind regards,
czed
Edit:
Clearified what I ment.
It should work. Here's a working fiddle. Check console for nested loaded data.
