What is the best practice to create an object via mutation connected to another object.
Using the following schema:
type Question #model {
id: ID!
text: String!
answers: [Answer] #connection(name: "QuestionAnswers")
}
type Answer #model {
id: ID!
text: String!
question: Question #connection(name: "QuestionAnswers")
}
The following (and variants of it) fail:
mutation CreateAnswer {
createAnswer(input: {
text:"Yes",
question: {
id: "9d38c759-6b64-4c1f-9e0e-d3b95a72b3a8"
}
})
{
id
}
}
Serverside code:
mutation CreateAnswer($input: CreateAnswerInput!) {
createAnswer(input: $input) {
id
text
question {
id
text
answers {
nextToken
}
}
}
}
With the above, receiving the following error:
"Validation error of type WrongType: argument 'input' with value
'ObjectValue{objectFields=[ObjectField{name='text',
value=StringValue{value='3'}}, ObjectField{name='question',
value=ObjectValue{objectFields=[ObjectField{name='id',
value=StringValue{value='9d38c759-6b64-4c1f-9e0e-d3b95a72b3a8'}}]}}]}'
contains a field not in 'CreateAnswerInput': 'question' #
'createAnswer'"
Seems that this may be a naming convention in AppSync. The below worked for me:
mutation createAnswer {
createAnswer (input: {
text: "5"
answerQuestionId: "9d38c759-6b64-4c1f-9e0e-d3b95a72b3a8"
}) {
id
}
Adding answer to QuestionId was what was needed.

I always get Syntax Error: Unterminated string when I try to update my database using javascript strapi sdk. this.chapter.content is a html string generated by ckeditor. How can I escape this string to update my database using graphql?
async updateChapter() {
const q = `
mutation {
updateChapter(input: {
where: {
id: "${this.$route.params.chapterId}"
},
data: {
content: "${this.chapter.content.replace(/[.*+?^${}()|[\]\\]/g, '\\$&').replace(/(?:\r\n|\r|\n)/g, '\n')}"
title: "${this.chapter.title}"
}
}) {
chapter{
title
id
content
}
}
}
`;
const res = await strapi.request("post", "/graphql", {
data: {
query: q
}
});
this.chapter = res.data.chapter;
}
Technically you could use block string notation to get around this issue. However, you really should supply dynamic input values using variables instead of string interpolation. This way you can easily provide any of sort of values (strings, numbers, objects, etc.) and GraphQL will parse them accordingly -- including strings with line breaks.
const query = `
mutation MyMutation ($chapterId: ID!, $content: String!, $title: String!) {
updateChapter(input: {
where: {
id: $chapterId
},
data: {
content: $content
title: $title
}
}) {
chapter{
title
id
content
}
}
}
`
const variables = {
chapterId: '...',
content: '...',
title: '...',
}
const res = await strapi.request("post", "/graphql", {
data: {
query,
variables,
},
})
Note that $chapterId may need to be of the type String! instead if that's what's called for in the schema. Since variables can also be input object types, instead of providing 3 different variables, you could also provide a single variable to be passed to the input argument instead:
const query = `
mutation MyMutation ($input: SomeInputObjectTypeHere!) {
updateChapter(input: $input) {
chapter{
title
id
content
}
}
}
`
const variables = {
input: {
where: {
id: '...',
},
data: {
content: '...',
title: '...',
},
},
}
Again, just replace SomeInputObjectTypeHere with the appropriate type in your schema.
Another solution maybe help
Code with issue: For example mainReason and actionTaken fields are text inputs and data contains some white spaces. This action give error: Unterminated string
mutation { updateApplicationForm(input:{ where:{id:"${ticketData.id}"}
data:{
mainReason: "${ticketData.mainReason}"
actionTaken: "${ticketData.actionTaken}"
appStatus: ${ticketData.appStatus}
action: "${ticketData.action}"
}
Fix this problem with JSON.stringify method
mutation { updateApplicationForm(input:{ where:{id:"${ticketData.id}"}
data:{
mainReason:${JSON.stringify(ticketData.mainReason)}
actionTaken:${JSON.stringify(ticketData.actionTaken)}
appStatus: ${ticketData.appStatus}
action: "${ticketData.action}"
}
I want to validate an object array inside nested object array
FormData:Array[8]
0:Object
group:Object
id:1
cards:Array[8]
0:Object
id:2253
service:Object
name:"Service Name"
...
I need to validate from service only the name
I try with something like this, but no success...
validations() {
return {
FormData: {
$each: {
group: {
cards: {
$each: {
service: {
name: {
required
}
}
}
}
}
}
}
}
}
Seems like the $each is not working as i want to, what im doing wrong how can i get to correct nested object with $each ?
What is the best approach for accessing a single nested record in Ember?
The JSON response which we are trying to manipulate looks gets returned as the following: (the attribute being targeted is the tradeIdentifier property)
trade:
tradeIdentifier:"83f3f561-62af-11e7-958b-028c04d7e8f9"
tradeName:"Plumber"
userEmail:"test#gmail.com"
The project-user model looks partially like:
email: attr('string'),
trade:attr(),
tradeId: attr(),
The project-user serializer looks partially like:
export default UndefinedOmitted.extend(EmbeddedRecordsMixin, {
primaryKey: 'userRoleId',
attrs: {
'email': { key: 'userEmail' },
'trade': { key: 'trade' },
'tradeId': { key: 'tradeIdentifier' },
},
});
The trade attr here is a placeholder to make sure that the data was accessible.
I would like to be able to access the tradeIdentifier without having to do the following in the component:
const trade = get(formRole, 'trade');
if (trade) {
set(formProps, 'tradeId', trade.tradeIdentifier);
}
Have tested creating a trade-id transform (referenced via tradeId: attr('trade-id')), however to no avail.
export default Transform.extend({
deserialize(val) {
const trade = val;
const tradeId = val.tradeIdentifier;
return tradeId;
},
serialize(val) {
return val;
},
});
Can anyone suggest where I'm going wrong?
A transform seems a bit overkill for what I'm trying to achieve here, however it does the job. Managed to get it working by modifying the following:
In serializers/project-user.js:
'tradeId': { key: 'trade' },
Note that this references the property in the payload to transform, not the property being targeted (which was my mistake).
In models/project-user.js:
tradeId: attr('trade-id'),
Attribute references the transform.
In transform/trade-id.js:
export default Transform.extend({
deserialize(val) {
let tradeId = val
if (tradeId) {
tradeId = val.tradeIdentifier;
}
return tradeId;
},
serialize(val) {
return val;
},
});
If there's a simpler solution outside of transforms, I would still be open to suggestions.
I have two Models:
River.associate = models => {
River.hasMany(models.Fish, { as: 'Fishes' });
};
Fish.associate = models => {
Fish.belongsTo(models.River);
};
type River {
id: ID!
name: String!
alternative: String!
geojson: JSON
fishes: [Fish]
}
type Fish {
id: ID!
name: String!
}
How would I findAll Rivers given a list of Fish ID's? Im not sure how the query must look for this for graphql and sequelize?
type Query {
river(id: ID!): River
**rivers(fishIds: ARRAY): River ??????**
fishes: [Fish]
}
Query: {
rivers: (_, { fishIds }) => {
return River.findAll({
where: {
fishes: fishIds
}
});
},
}
You can specify WHERE clauses for each of the models you include. Moreover, doing so will convert the eager load to an inner join (which is what you want), unless you explicitly set the required param to false.
That means you should be able to do something like:
River.findAll({ include:
[
{
model: Fish,
where: { id: fishIds }
},
],
})
I can share an item easily using an InvokeActionItem in a Page but I need to be able to call it in a listview item. I've managed to trigger an invoke, but I cannot figure out how to add data when triggering it. I keep getting an error message of
InvocationPrivate::setQuery: you are not allowed to change InvokeQuery object
Note: I am trying to do this in purely QML, I will do it via c++ if necessary but QML would be preferable.
Code that works inside a Page object:
actions: [
InvokeActionItem {
ActionBar.placement: ActionBarPlacement.OnBar
title: "Share"
query {
mimeType: "text/plain"
invokeActionId: "bb.action.SHARE"
}
onTriggered: {
//myTextProperty is a string variable property for the page.
data = myTextProperty;
}
}
]
The code I've tried to use in the other item is as follows, but does NOT work:
Container {
gestureHandlers: [
TapHandler {
LongPressHandler {
onLongPressed: {
console.log("Longpress");
invokeQuery.setData("test");
invokeShare.trigger("bb.action.SHARE");
}
}
]
attachedObjects: [
Invocation {
id: invokeShare
query: InvokeQuery {
id:invokeQuery
mimeType: "text/plain"
}
}
]
}
Is there a way to change the data for an invoke purely with QML or do I need to just run it through c++ instead?
After a fair amount of browsing forums and testing various methods, I have finally found one that works.
Add the following in your attachedObjects:
attachedObjects: [
Invocation {
id: invokeShare
query: InvokeQuery {
id:invokeQuery
mimeType: "text/plain"
}
onArmed: {
if (invokeQuery.data != "") {
trigger("bb.action.SHARE");
}
}
}
]
Then wherever you need to call the invocation do the following:
invokeQuery.mimeType = "text/plain"
invokeQuery.data = "mytext";
invokeQuery.updateQuery();
Note that if you do not do a check in the onArmed for data it will automatically call the invocation on creation - in the case of a listview this can result in 20+ screens asking you to share on bbm... ;)
You can actually use the InvokeActionItem, you just have to call updateQuery to retrigger the invokeQuery.
When the ListItemData changes, the binding will cause the values to update.
InvokeActionItem {
enabled: recordItem.ListItem.data.videoId != undefined
id: invokeAction
query{
uri: "http://www.youtube.com/watch?v=" + recordItem.ListItem.data.videoId
onQueryChanged: {
updateQuery()
}
}
}
For remove "InvocationPrivate::setQuery: you are not allowed to change InvokeQuery object" message I use this:
attachedObjects: [
Invocation {
id: invoke
query {
mimeType: "text/plain"
invokeTargetId: "sys.bbm.sharehandler"
onDataChanged: {
console.log("change data")
}
}
onArmed: {
if (invoke.query.data != "") {
invoke.trigger("bb.action.SHARE");
}
}
}
]
function shareBBM(){
invoke.query.setData("TEXT TO SHARE");
invoke.query.updateQuery();
}
