I have a simple test database that I cant get to filter. I indexed the category in the rules:
"questions":{
".indexOn": ["category"]
},
My filter for the quiz app:
/questions.json?orderBy="category"&equalTo="Basics"&print=pretty
and my database:
"-MKoucSP33zm4jC43AnY" : {
"title" : {
"answers" : [ {
"score" : 30,
"text" : "Pineapple"
}, {
"score" : 5,
"text" : "Ham"
}, {
"score" : 20,
"text" : "Yogurt"
}, {
"score" : 10,
"text" : "Crab"
} ],
"category" : "Basics",
"questionId" : "101",
"questionImage" : "",
"questionLink" : "",
"questionText" : "What topping do you like the best on pizza?"
}
}
The category property is nested under the title node, so the property you need to order/filter on is title/category:
/questions.json?orderBy="title/category"&equalTo="Basics"&print=pretty
You'll also need to update your index definition for that path, so:
"questions": { ".indexOn": "title/category" }
Working example: https://stackoverflow.firebaseio.com/64596200/questions.json?orderBy="title/category"&equalTo="Basics"

Here is my database entry structure, it has a nested document called friends, I want to compare two different _id's friends list in dart using mongo_dart
{
"_id" : ObjectId("60ae06074e162995281b4666"),
"email" : "one#one.com",
"emailverified" : false,
"username" : "one#one.com",
"displayName" : "complete n00b",
"phonenumber" : "",
"dob" : "",
"points" : 0,
"friends" : [
{
"username" : "three#one.com",
"sent" : ISODate("2021-05-26T10:01:30.616Z")
},
{
"username" : "six#one.com",
"sent" : ISODate("2021-05-26T10:43:16.822Z")
}
]
}
Here is my code, but I am not getting any returns
Future<Map> commonFriends(store, myObjectId, theirObjectId) async {
var commonList = await store.aggregate([
{
'\$project': {
'friends': 1,
'commonToBoth': {
'\$setIntersection': [
{'_id': myObjectId, 'friends': '\$username'},
{'_id': theirObjectId, 'friends': '\$username'}
]
},
}
}
]);
return commonList;
}
I am getting an error from db.dart which is apart of mongo_dart package. The error is "Exception has occurred.
Map (4 items)"
How could I query this data in this way:
I would like to ignore the CurrentSubAdministrativeArea child and iterate every each sub child and find the right userKey
Actually I'm using this code, that isnt working:
self.ref.child("Ads").child("CurrentSubAdministrativeArea")
/*HERE I would like to ignore the childs*/
.queryOrdered(byChild: "userKey").queryEqual(toValue: uid).observeSingleEvent(of:.value, with: { (snapshot) in

You could denormalize your data in such a way your query is easy to build and execute.
Together with the data structure you already have you would have another node (ie. another data structure) like
{
"AdsByUsers" : {
"OsJRc98sqxPx70iqxFtoqerMzHH2": {
"Mantova",
"Milano",
...
},
"abcde88qxPx70iqxFtoqerMzKh5": {
"Firenze",
...
}
With NoSQL database you should not hesitate to duplicate data in such a way your queries are easy and fast to execute.
I'm using neo4j with spring data, when I store an object with inside a relation I get as a result of the findAll a corrupted json. I never get this error when I query the objects one at time.
Even more strange the first one in the list is correct but the second has this error. The error is at the edge field. Any idea?

I want to sort my query results following some boost rules and in the same time i want them to be sorted as possible by creation date, if i add a created_at sort, it changes everything and my results are not relevant anymore. So i guess the only way to do that is to boost created_at field (the newest has the biggest bonus in calculating score for that boost) but i dont know how to implement it. This is my query:
query = {
"query" : {
"bool" : {
"must" : [
{
"range" : {
"deadline" : {
"gte" : "2016-05-30T11:39:10+02:00"
}
}
},
{
"terms" : {
"state" : [
"open"
]
}
},
{
"query_string" : {
"query" : "chant",
"default_operator" : "AND",
"analyzer" : "search_francais",
"fields" : [
"title^6",
"description",
"brand",
"category_name"
]
}
}
]
}
},
"filter" : {
"and" : [
{
"geo_distance" : {
"distance" : "40km",
"location" : {
"lat" : 48.855736,
"lon" : 2.32927300000006
}
}
}
]
},
"sort" : [
{
"_score" : "desc"
},
#{
# "created_at" : "desc" ==> i tried this but it doesnt change results
#}
]
}
Try adding your condition in should block.
i)If the created date should be closer to come value in the search query or you have any idea on how close the date should be, give a range query.
ii) If you are not sure of all those values, decay function can be used. In this case, query shall be changed to function query.

"query" : {
"bool" : {
"must" : [
{
"range" : {

Is it possible to create Salesreceipt without product/service value through QBO API? I have tried through API but it's not reflecting rate value and storing description value only.
If I remove ItemRef attribute(in request body) then it's reflecting rate and amount values and it's assigning some default and random product/service.
It is possible directly in QBO UI.
Request body where only description value storing:
{
"TxnDate" : "2016-05-27",
"Line" : [ {
"Amount" : 2222.00,
"Description" : "hi chk",
"DetailType" : "ItemReceiptLineDetail",
"ItemReceiptLineDetail" : {
"ItemRef" : { },
"Qty" : 1,
"UnitPrice" : 2222
} }
],
"CustomerRef" : {
"value" : "67"
},
"CustomerMemo" : {
"value" : "Thanks for your business! We appreciate referrals!"
},
"TotalAmt": 2222.00,
"PrivateNote" : "",
"CustomField" : [ {
"DefinitionId" : "1",
"Type" : "StringType",
"StringValue" : ""
} ]
}
Request body where default product/service assigning:
{
"TxnDate" : "2016-05-27",
"Line" : [ {
"Amount" : 2222.00,
"Description" : "hi chk",
"DetailType" : "ItemReceiptLineDetail",
"ItemReceiptLineDetail" : {
"Qty" : 1,
"UnitPrice" : 2222
} }
],
"CustomerRef" : {
"value" : "67"
},
"CustomerMemo" : {
"value" : "Thanks for your business! We appreciate referrals!"
},
"TotalAmt": 2222.00,
"PrivateNote" : "",
"CustomField" : [ {
"DefinitionId" : "1",
"Type" : "StringType",
"StringValue" : ""
} ]
}
No.
QuickBooks Online does not support this.
