I have three Post in my collection of three different User
I am trying to fetch the post in my Views Session (Html, Css) Part
But I need to filter the other two post Posted from other two User
because I have some block functionality in my View Section. So all post are
allowed but the user I have blocked her/his post not visible to me and mine to him.
BlockedByUser : (This is my Post Json Data)
{
"_id" : ObjectId("591729b52bb30a19afc9b89d"),
"createdTime" : ISODate("2017-05-13T15:43:49.381Z"),
"isDeleted" : false,
"Message" : "Message Two",
"postedBy" : ObjectId("598adbefb3bf0b85f92edc3b"),
"recipient" : [
ObjectId("598ae453b3bf0b85f92ee331"),
ObjectId("5910691ae2bcdeab80e875f0")
],
"updatedTime" : ISODate("2017-05-20T09:24:39.124Z")
}
Below two user Post Data that I have blocked And
In his recipient Array Key stores my Id recipient [598adbefb3bf0b85f92edc3b]
Block User One :
{
"_id" : ObjectId("591729b52bb30a19afc9b89d"),
"createdTime" : ISODate("2017-05-13T15:43:49.381Z"),
"isDeleted" : false,
"Message" : "Message One",
"postedBy" : ObjectId("598ae453b3bf0b85f92ee331"),
"recipient" : [
ObjectId("598adbefb3bf0b85f92edc3b"),
ObjectId("5910691ae2bcdeab80e875f0"),
ObjectId("598ac93cb3bf0b85f92ece44"),
],
"updatedTime" : ISODate("2017-05-20T09:24:39.124Z")
}
Same as above
Block User Two :
{
"_id" : ObjectId("591729b52bb30a19afc9b89d"),
"createdTime" : ISODate("2017-05-13T15:43:49.381Z"),
"isDeleted" : false,
"Message" : "Message One",
"postedBy" : ObjectId("598ac93cb3bf0b85f92ece44"),
"recipient" : [
ObjectId("598adbefb3bf0b85f92edc3b"),
ObjectId("5910691ae2bcdeab80e875f0"),
ObjectId("598ae453b3bf0b85f92ee331")
],
"updatedTime" : ISODate("2017-05-20T09:24:39.124Z")
}
This is Block Collection that I have created and two blocked user Id with blockUserId key
Block Details One :
{
"_id" : ObjectId("598da2f0b88b0c2b0c735234"),
"blockUserId" : ObjectId("598ae453b3bf0b85f92ee331"),
"blockById" : ObjectId("598adbefb3bf0b85f92edc3b"),
"updatedDate" : ISODate("2017-08-11T12:28:32.145Z"),
"createdDate" : ISODate("2017-08-11T12:28:32.145Z"),
"isBlock" : "true",
"__v" : 0
Block Details Two
{
"_id" : ObjectId("598da558b88b0c2b0c735236"),
"blockUserId" : ObjectId("598ac93cb3bf0b85f92ece44"),
"blockById" : ObjectId("598adbefb3bf0b85f92edc3b"),
"updatedDate" : ISODate("2017-08-11T12:38:48.772Z"),
"createdDate" : ISODate("2017-08-11T12:38:48.772Z"),
"isBlock" : "true",
"__v" : 0
}
I have fetch these blocked collection and store two user blockUserId id in array
arrOne = ["598ae453b3bf0b85f92ee331", "598ac93cb3bf0b85f92ece44"]
And i am applying this query in mongoose db:
query = {$or: [{$and: [{ $or: [{ postedBy: req.params.id},
{recipient: req.params.id}
]
}, { createdTime: { $gt: endTime, $lt: startTime } }
]},{postedBy: {$ne: arrOne}}
]
};
}
But it will return undefined value
I am trying to fetch only my Post or Other user Post that not Blocked my Me, And Blocked User Post will not visible to me
I have to Implement where clause and it works
var query = { $and: [{ $or: [{ postedBy: req.params.id }, { recipient: req.params.id }] }, { "createdTime": { $gt: endTime, "$lt": startTime } }] };
CollectionName.find(query).where('postedBy').nin(blocklist).exec(function(err, response);

I am trying to do some basic validation on my firebase database to ensure when an order is submitted that both email and mobile are present.
This is the rule I thought who achieve this but I am getting an error in the simulator say write access denied
{
"rules": {
"Orders": {
".read": true,
".write": true,
"$order_id": {
".validate": "newData.hasChildren(['email', 'phone'])"
}
}
}
}
This is the child node of /Orders
"-KeDyBIqnzNik0vOCEfQ" : {
"date" : "2017-03-02T23:22:32+1100",
"email" : "beanindustries#gmail.bean",
"items" : [ {
"description" : "Almond",
"name" : "Cappuccino",
"price" : ".5",
"qty" : 1
}, {
"description" : "Almond",
"name" : "Cappuccino",
"price" : ".5",
"qty" : 1
} ],
"name" : "Mr Bean",
"notes" : "\n\n",
"phone" : "0412258499",
"status" : "new"
}
So, it turns out I wasnt using data section within the simulator which is why my validations failed. I have since pasted the above JSON into that box and the validations appear to be working as expected
The title of the question is self explanatory. I want to know what differences are there in JSON Document A which comes from API request and JSON Document B which is already in Mongo DB.how to get changes column name and data also.. i am creating log..that's why i want...
Below is the code of what I'm trying:
NodeJS APICode//
function Updatejob(req, res) {
return function (jobSchedule) {
var obj = new Date();
CompareJSON(req, mongodbjson);
return Job.create(req.body).then(.....)
}
Already Data in Mongodb before Update Record
{
"_id" : ObjectId("586d1032aef194155028e9c7"),
"history" : [
{
"_id" : ObjectId("586d1032aef194155028e9c4"),
"updated_by" : "",
"details" : "Job Created",

"datetime" : ISODate("2017-01-04T15:09:38.465Z")
}
],
"current_status" : "Pending",
"time" : 0
}

You can use jsondiffpatch:
var delta = jsondiffpatch.diff(object1, object2);
See:
https://www.npmjs.com/package/jsondiffpatch
I have this JSON structure:
{
"groups" : {
"-KBxo9-RoY0eowWKeHkU" : {
"author" : "rsenov",
"members" : {
"-KBxo7ZU6McsmDOxyias" : true,
"-KBxo8_TUTW6NZze6xcd" : true,
"rsenov" : true
},
"name" : "Prueba 3"
}
},
"users" : {
"-KBxo7ZU6McsmDOxyias" : {
"avatar" : "owl2",
"groups" : {
"-KBxo9-RoY0eowWKeHkU" : true
},
"isUser" : false,
"name" : "Pepa"
},
"-KBxo8_TUTW6NZze6xcd" : {
"avatar" : "monkey",
"groups" : {
"-KBxo9-RoY0eowWKeHkU" : true
},
"isUser" : false,
"name" : "Lolas"
},
"rsenov" : {
"avatar" : "guest",
"groups" : {
"-KBxo9-RoY0eowWKeHkU" : true
},
"isUser" : true,
"name" : "Ruben",
}
}
}
and the security&rules file is:
{
"rules": {
".read": true,
".write": true,
"users": {
".indexOn": ["email", "groups"]
},
"groups": {
".indexOn": ["author", "name"]
}
}
}
I'm trying to run a query in order to get the ChildChanged snapshot:
DataService.dataService.USERS_REF.queryOrderedByChild("groups").queryEqualToValue(currentGroup.groupKey).observeEventType(.ChildChanged, withBlock: {snapshot in
print(snapshot)
})
DataService.dataService.USERS_REFcorresponds to the url that point to the "users" key, and currentGroup.groupKeyis equal to -KBxo9-RoY0eowWKeHkUin this case.
According to this query, I should get the snapshot of the child that has changed. For example, if I replace the user name "Pepa" to "Test", I should get the snapshot:
"-KBxo7ZU6McsmDOxyias" : {
"avatar" : "owl2",
"groups" : {
"-KBxo9-RoY0eowWKeHkU" : true
},
"isUser" : false,
"name" : "Test"
}
but this query never get's called...
Is there something wrong in my query?
"I'm trying to run a query in order to get the ChildChanged snapshot:" is a little odd.
You can query for data, or observe a node via ChildChanged.
If you just want to be notified of changes within the users node, add an observer to that node and when Pepa changes to Test, your app will be notified and provided a snapshot of the user node that changed.
var ref = Firebase(DataService.dataService.USERS_REF)
ref.observeEventType(.ChildChanged, withBlock: { snapshot in
println("the changed user is: \(snapshot.value)")
})
Oh, and no need for queryOrderedByChild since the snapshot will only contain the single node that changed.
I want update a array value that is nested within an array value: i.e. set
status = enabled
where alerts.id = 2
{
"_id" : ObjectId("5496a8ed49847b6cd7c7b350"),
"name" : "joe",
"locations" : [
{
"name": "my location",
"alerts" : [
{
"id" : 1,
"status" : null
},
{
"id" : 2,
"status" : null
}
]
}
]
}
I would have used the position $ character, but cannot use it twice in a statement - multi positional operators are not supported yet: https://jira.mongodb.org/browse/SERVER-831
How do I issue a statement to only update the status field of an alert matching an id of 2?
UPDATE
If I change the schema as follows:
{
"_id" : ObjectId("5496ab2149847b6cd7c7b352"),
"name" : "joe",
"locations" : {
"my location" : {
"alerts" : [
{
"id" : 1,
"status" : "enabled"
},
{
"id" : 2,
"status" : "enabled"
}
]
},
"my other location" : {
"alerts" : [
{
"id" : 3,
"status" : null
},
{
"id" : 4,
"status" : null
}
]
}
}
}
I can then use:
update({"locations.my location.alerts.id":1},{$set: {"locations.my location.alerts.$.status": "enabled"}});
Problem is I cannot create indexes on the alert id :-(
it may be better of modelled as such, specially if an index on location and,or alerts.id is needed.
{
"_id" : ObjectId("5496a8ed49847b6cd7c7b350"),
"name" : "joe",
"location" : "myLocation",
"alerts" : [{
"id" : 1,
"status" : null
},
{
"id" : 2,
"status" : null
}
]
}
{
"_id" : ObjectId("5496a8ed49847b6cd7c7b350"),
"name" : "joe",
"location" : "otherLocation",
"alerts" : [{
"id" : 1,
"status" : null
},
{
"id" : 2,
"status" : null
}
]
}
I think you are having a wrong tool for the job. What you have in your example is relational data and it's much easier to handle with relational database. So I would suggest to use SQL-database instead of mongo.
But if you really want to do it with mongo, then I guess the only option is to fetch the document and modify it and put it back.
I have a mongo json object as follows
{
"_id" : new BinData(3, "RDHABb22XESWvP83FplqJw=="),
"name" : "NEW NODE",
"host" : null,
"aet" : null,
"studies" : ["1.3.12.2.1107.5.99.3.30000008061114424970500000589"],
"testcases" : [new BinData(3, "Zhl+zIXomkqAd8NIkRiTjQ==")],
"sendentries" : [{
"_id" : "1.3.12.2.1107.5.99.3.30000008061114424970500000589",
"Index" : 0,
"Type" : "Study"
}, {
"_id" : "cc7e1966-e885-4a9a-8077-c3489118938d",
"Index" : 1,
"Type" : "TestCase"
}]
}
The fields "Studies" and "TestCases" are now obsolete and I am now storing that information in a new field called SendEntries. I would like to get rid of the Studies and TestCases from the old entries and unmap those fields going forward. I want to know how I can update my current collections to get rid of the Studies and TestCases fields.
I'm just few weeks into Mongo.
You can use the $unset operator with update.
db.collection.update({},
{ $unset: {
"studies": "",
"testcases": ""
},
{ "upsert": false, "muti": true }
)
And that will remove all of the fields from all of your documents in your collection
Use $unset, there's a manual page e.g.
db.yourCollection.update( { },
{ $unset: {
Studies: "",
testcases: ""
}
},
{ multi: true }
)
