I have a following shema.
{
id:week
output:{
headerValues:[
{startDate:"0707",headers:"ID|week"},
{startDate:"0715",headers:"ID1|week1"},
{startDate:"0722",headers:"ID2|week2"}
]
}
}
I have to add a new field into headerValues array like this:
{
id:week
output:{
headerValues[
{startDate:"0707",headers:"ID|week",types:"used"},
{startDate:"0715",headers:"ID1|week1",types:"used"},
{startDate:"0722",headers:"ID2|week2",types:"used"}
]
}
}
I tried different approaches like this:
1)
db.CollectionName.find({}).forEach(function(data){
for(var i=0;i<data.output.headerValues.length;i++) {
db.CollectionName.update({
"_id": data._id, "output.headerValues.startDate":data.output.headerValues[i].startDate
},
{
"$set": {
"output.headerValues.$.types":"used"
}
},true,true
);
}
})
So, In this approach it is executing script and then failing. It is updating result with failed statement.
2)
Another approach I have followed using this link:
https://jira.mongodb.org/browse/SERVER-1243
db.collectionName.update({"_id":"week"},
{ "$set": { "output.headerValues.$[].types":"used" }
})
But it fails with error:
cannot use the part (headerValues of output.headerValues.$[].types) to
traverse the element ({headerValues: [ { startDate: "0707", headers:
"Id|week" } ]}) WriteError#src/mongo/shell/bulk_api.js:469:48

I have searched with many different ways which can update different arrays object by adding new field to each object but no success. Can anybody please suggest that what am I doing wrong?
Your query is {"_id" : "week"} but in your data id field is week
So you can change {"_id" : "week"} to {"id" : "week"} and also update your mongodb latest version
db.collectionName.update({"id":"week"},
{ "$set": { "output.headerValues.$[].types":"used" }
})

I am trying to find out a way to fetch nearby events using GraphQL meetup.com API. After digging into the documentation for quite some time, I wasn't able to find a query that suits my needs. Furthermore, I wasn't able to find old, REST, documentation, where, the solution for my case might be present.
Thanks in advance !
This is what I could figure out so far, the Documentation for SearchNode is missing, but I could get id's for events:
query($filter: SearchConnectionFilter!) {
keywordSearch(filter: $filter) {
count
edges {
cursor
node {
id
}
}
}
}
Input JSON:
{ "filter" : {
"query" : "party",
"lat" : 43.8,
"lon" : -79.4, "radius" : 100,
"source" : "EVENTS"
}
}
Hope that helps. Trying to figure out this new GraphQL API
You can do something like this (customize it with whatever fields you want from Event):
const axios = require('axios');
const data = {
query: `
query($filter: SearchConnectionFilter!) {
keywordSearch(filter: $filter) {
count
edges {
cursor
node {
id
result {
... on Event {
title
eventUrl
description
dateTime
going
}
}
}
}
}
}`,
variables: {
filter: {
query: "party",
lat: 43.8,
lon: -79.4,
radius: 100,
source: "EVENTS",
},
},
};
axios({
method: "post",
url: `https://api.meetup.com/gql`,
headers: {
Authorization: `Bearer YOUR_OAUTH_ACCESS_TOKEN`,
},
data,
})
I want to query user where updatedAt is less than or equal today using aggregate because I'm doing other stuff like sorting by pointers.
I'm using cloud code to define the query from the server.
I first tried using mongoDB Compass to check my query using ISODate and it works, but using it in NodeJS seems not working correctly.
I also noticed about this problem that was already fix, they say. I also saw their tests.
Here's a link to that PR.
I'm passing date like this:
const pipeline = [
{
project: {
_id: true,
process: {
$substr: ['$_p_testdata', 12, -1]
}
}
},
{
lookup: {
from: 'Test',
localField: 'process',
foreignField: '_id',
as: 'process'
}
},
{
unwind: {
path: '$process'
}
},
{
match: {
'process._updated_at': {
$lte: new Date()
}
}
}
];
const query = new Parse.Query('data');
return query.aggregate(pipeline);
I expect value to be an array with length of 4 but only give me empty array.
I was able to fetch data without match date.
Please try this:
const pipeline = [
{
match: {
'editedBy.updatedAt': {
$lte: new Date()
}
}
}
];
I have a graphql endpoint where this query can be entered:
fragment ChildParts {
id
__typename
}
fragment ParentParts {
__typename
id
children {
edges{
node {
...ChildParts
}
}
}
query {
parents {
edges
nodes {
...ParentParts
}
}
}
}
When executed, it returns something like this:
"data": {
"edges": [
"node": {
"id": "<some id for parent>",
"__typename": "ParentNode",
"children": {
"edges": [
node: {
"id": "<some id for child>",
"__typename": "ChildNode"
},
...
]
}
},
...
]
}
Now, with apollo client, after a mutation, I can read this query from the cache, and update / add / delete any ParentNode, and also any ChildNode, but I have to go over the structure returned by this query.
Now, I'm looking for a possibility to get a list of ChildNodes out of the cache (which has those already, as the cache is created as a flat list), to make the update of nested data a bit easier. Is there a possibility of reading a query out of the cache, without having read the same query from the server before?
You can use the client's readFragment method to retrieve any one individual item from the cache. This just requires the id and a fragment string.
const todo = client.readFragment({
id,
fragment: gql`
fragment fooFragment on Foo {
id
bar
qax
}
`,
})
Note that id here is the cache key returned by the dataIdFromObject function -- if you haven't specified a custom function, then (provided the __typename and id or _id fields are present) the default implementation is just:
${result.__typename}:${result.id || result._id}
If you provided your own dataIdFromObject function, you'll need to provide whatever id is returned by that function.
As #Herku pointed out, depending on the use case, it's also possible to use cache redirects to utilize data cached for one query when resolving another one. This is configured as part of setting up your InMemoryCache:
const cache = new InMemoryCache({
cacheRedirects: {
Query: {
book: (_, args, { getCacheKey }) =>
getCacheKey({ __typename: 'Book', id: args.id })
},
},
})
Unfortunately, as of writing this answer, I don't believe there's any method to delete a cached item by id. There's on going discussion here around that point (original issue here).
I have a list similar to this:
var list = [
{
stack: [
{
file: 'abc'
}
]
},
{
stack: [
{
file: 'abc'
},
{
file: 'abc'
}
]
}
];
I want to change every file name with e.g 'def'. How to do that by using ramda ?
I tried things like:
var trans = {
file: replace('abc', 'def')
};
var f = R.evolve(trans)
var f2 = R.map(f)
R.map(f2, list)
But it doesn't work. I need to include stack field in solution somehow.
Well, it's not pretty, but I think this will do it:
R.map(R.over(
R.lensProp('stack'),
R.map(R.over(R.lensProp('file'), R.replace('abc', 'def')))
))(list)
You could probably also use an evolve inside, but lenses are pretty powerful, and more generally useful.
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();
}
