i've build Hyperledger Fabric channel and it was running well. But, i wanna get just some attributes only from that Hyperledger that have data structure like this
[
{
"name": "name-1",
"class": "IV-A",
"address": "dummy st.",
"handphone": "xxx-xxx-xxx-xxx",
"status": "inactive"
},
{
"name": "name-2",
"class": "IV-A",
"address": "dummy st. 7th",
"handphone": "xxx-xxx-xxx-xxx",
"status": "active"
},...
]
i wanna get just some attributes (name, address, and status), so we can get the return like this
[
{
"name": "name-1",
"address": "dummy st.",
"status": "inactive"
},
{
"name": "name-2",
"address": "dummy st. 7th",
"status": "active"
},...
]
is it possible to get those attributes via hyperledger directly without using couchdb? i know if we use couchdb we just need to create the view with some query in the "emit()", but is there any way to get that in hyperledger using chaincode or selector?
Thank you in advance.
I'm not sure about your Hyperledger Fabric environment and data.
But you can check out this chaincode.
OR if you are OK to use 'invoke function', you can return value what you want.
return shim.Success([]byte($value))

I am new to MongoDB. This is a MERN project. I am using the MongoDB database. I am trying to delete the comments using id which are nested in an array of objects. My document looks like this,

}
this is a big object called announcements which has a comments array and that contains an array of objects which are comments. And if someone replies to a comment I am making another array called comments and storing all the replies objects.
I want to delete the object using ._id: 60aa912b301ccc397057ded6, which is the reply object with the content "1".
I have tried to find, findById, findOneAndRemove, findOneAndDelete it's not finding the document.
You could perhaps change the way you structure the comments and not nest them? Since each comment already has a unique id, nesting them only makes it more difficult to access the comment object, and it's a rabbit's hole, where the nesting might never end?
I propose you add an property in the comment object A to point to other comment object B, if A is a reply or quote of B.
That way you can have an array of comment objects and modify them must easily.
Cheers.
I am 500% sure it used to work and all of a sudden this is broken. The card for getting input is no longer passing the value back to nodejs.
The card looks like below:
{
"type": "AdaptiveCard",
"body": [
{
"type": "TextBlock",
"text": "Note text"
},
{
"type": "Input.Text",
"placeholder": "Type a note",
"isMultiline": true,
"id": "noteIdVal"
}
],
"actions": [
{
"type": "Action.Submit",
"title": "Save",
"data": { "action" : "add_note", "objNumber": objId, "objType": objectType }
},
{
"type": "Action.Submit",
"title": "Cancel",
"data" : {"action": "cancel"}
}
],
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json"
}
On the submit action, in my nodejs i am getting the data in the values node which are passed in the data field. However, it is no longer attaching noteIdVal. Did something changed from MS side?
MS Teams Adaptive card required special property with the name msteams to the object in an object submit action’s data property in order to access this functionality.
{
"type": "Action.Submit",
"title": "Click me for messageBack",
"data": {
"msteams": {
"type": "messageBack",
"displayText": "I clicked this button",
"text": "text to bots",
"value": "{\"bfKey\": \"bfVal\", \"conflictKey\": \"from value\"}"
},
"extraData": {}
}
}
The type property is "messageBack" the submit action will behave like a messageBack card action, which is like a combination of imBack and postBack.
Reference :
Microsoft Docs for MS Teams Adaptive Card
So, may be useful to other folks here. I have two showCards and the content of both the show cards has a common text field with same id name "noteIdVal". As ultimately it is a single json and hence was the culprit.
Lesson, have all fields unique id values which is easy to miss when you have multiple show cards
I am pulling Recommendations from the Azure Advisor Rest Api and am not able to retrieve the extendedProperties values.
Specifically, I am looking for savings data from Recommendations of the Cost category.
In the following video at 58 seconds there is an example of the expected response.
https://www.youtube.com/watch?v=hAxrdmOAB8s
Are there specific permissions necessary to give my account in order to pull the data, or is the API not capable of supplying the values?
I am able to see the data in the portal, but the extendedProperties property is always empty.
I'm supposing you're trying the Recommendations - List API.
Essentially, extended properties expose additional information about a recommendation from Azure Advisor.
AFAIK, they need not be present for every recommendation, and shouldn't need additional privileges to list. It could just be the case that the type of recommendations you are receiving do not have any to list.
Here is a sample response that I received that has a mix of both:

Say I just wanted to get a list of all transactions that involved a specific asset (assuming I would need a query for this?). Should I use the TransactionRegistry or the Historian? What's the difference?
we have a current issue open for Historian to show history of changes/ deltas for a particular asset - https://github.com/hyperledger/composer/issues/991 As a workaround you can do the following - so for sample network trade-network with an asset Commodity (and a transaction class 'Trade') you could create a query eg:
query selectTransaction {description: "choose specific commodity asset"
statement: SELECT org.acme.biznet.Trade
WHERE (commodity == _$commodity ) }
On the difference:
Historian records all transaction activities (eg. create Asset, create participant, create identity etc etc - and also business network specific custom transactions like 'TransferAsset' or 'PlaceOrder') including (where assets / participants are concerned) what changed.
For the TransactionRegistry itself (ie a particular class - say 'TransferAsset' or 'PlaceOrder') this is stored in the Transaction registry for that class - you may have many Transaction classes in your business network. But nothing in here would be related to other activities, such as system activities, that also recorded in Historian records.
to query - you would do something like this (in a query file for example):
query myTransactions{
description: "return all transactions made (ie system transactions)"
statement: SELECT org.acme.sample.PlaceOrder
}
ie SELECT org.acme.sample.NAME_OF_TRANSACTION_CLASS
For Historian queries - eg
SELECT org.hyperledger.composer.system.HistorianRecord WHERE (transactionType == 'myTranType'
see more examples here -> https://www.ibm.com/developerworks/cloud/library/cl-create-powerful-blockchain-queries-with-hyperledger-composer/index.html
furthermore, to see the transaction data (deltas) for the asset id you're zoning in on - ie available through the transactionInvoked field of the transaction class (eg org.acme.trading.Trade transaction class). you could use REST APIs with loopback filters -eg either (both return a promise below):
return this.httpClient.get('http://localhost:3000/api/Trade?filter=%7B%22include%22%3A%22resolve%22%7D', {withCredentials: true}).toPromise();`
or
return this.httpClient.get('http://localhost:3000/api/Trade?filter=%7B%22include%22%3A%22resolve%22%7D').toPromise();
which has the {"include":"resolve"} filter to resolve relationships in the transaction class - each resolved transaction has the transaction deltas. Then you could look for the asset id in question.
Sample unresolved transaction class (below, followed by resolved txn class):
Not resolved:

I want to implement autocomplete on this.
However, when i see the demos present in algolia dashboard, i found out that it returns the complete documents.
I want to only match on user.displayName, place.name, and title
and return only these fields as suggestions in the autocomplete results instead of complete documents, which match.
I know I can create separate indexes for users, places;
But is this possible with only a single index??
Did you had a look at http://algolia.com/doc/tutorials/search-ui/autocomplete/auto-complete/ ?
It shows how to have a custom display from an index.
To match on on user.displayName, place.name, and title
you can configure the "searchable attributes" from the algolia dashboard.
