I am getting a JSON response and I want to display the contents obtained from this response on my HTML page using angular.
ngOnInit() {
this.http.get(this.url)
.subscribe(response =>{
this.users = response.json();
});
}
Above code returns an Object of JSON which cause an error if iterated using ngFor.
I have tried some answers available on StackOverflow regarding this problem but they cause compilation errors or give no results.
Here is JSON Object I'm getting
{
"_embedded" : {
"users" : [ {
"name" : "Ahmad",
"role" : "Admin",
"_links" : {
"self" : {
"href" : "http://localhost:8080/users/1"
},
"user" : {
"href" : "http://localhost:8080/users/1"
}
}
}, {
"name" : "Umar",
"role" : "User",
"_links" : {
"self" : {
"href" : "http://localhost:8080/users/2"
},
"user" : {
"href" : "http://localhost:8080/users/2"
}
}
}, {
"name" : "Ali",
"role" : "Admin",
"_links" : {
"self" : {
"href" : "http://localhost:8080/users/3"
},
"user" : {

}
}
}, {
"name" : "Waqas",
"role" : "User",
"_links" : {
"self" : {
"href" : "http://localhost:8080/users/4"
},
"user" : {
"href" : "http://localhost:8080/users/4"
}
}
} ]
},
"_links" : {
"self" : {
"href" : "http://localhost:8080/users{?page,size,sort}",
"templated" : true
},
"profile" : {
"href" : "http://localhost:8080/profile/users"
},
"search" : {
"href" : "http://localhost:8080/users/search"
}
},
"page" : {
"size" : 20,
"totalElements" : 4,
"totalPages" : 1,
"number" : 0
}
}
EDIT: HTML code with ngFor
<ul class="list-group">
<li
*ngFor="let user of users"
class="list-group-item">
{{ user }}
</li>
I am learning angular at the moment so please give some explanation with the answer.
You need to modify this
this.users = response.json();
to
this.users=response.json()._embedded.users
You need to modify this
this.users = response.json();
to
this.users = response.json()['_embedded']['users'];

I am trying to create a workspace add-on with a couple input boxes and a submit button. The servlet simply returns http endpoints in json code for the google add-on to read the code and build the card properly. However, I cannot seem to figure out how to get the text input values. What action do I need to call on button click to return an http endpoint with parsable json to the servlet?
Here is the code for creating the card:
{"renderActions" : {
"action" : {
"navigations" : [ {
"pushCard" : {
"header" : {
"title" : "NDA Form"
},
"sections" : [ {
"widgets" : [ {
"textParagraph" : {
"text" : "Please check for proper input!"
}
}, {
"textInput" : {
"label" : "Name",
"type" : "SINGLE_LINE",
"name" : "signerName"
}
}, {
"textInput" : {
"label" : "Email",
"type" : "SINGLE_LINE",
"name" : "email"
}
}, {
"textInput" : {
"label" : "Company Name",
"type" : "SINGLE_LINE",
"name" : "compName"
}
}, {
"textInput" : {
"label" : "Address",
"type" : "SINGLE_LINE",
"name" : "address"
}
}, {
"textInput" : {
"label" : "Date",
"type" : "SINGLE_LINE",
"name" : "date"
}
}, {
"buttonList" : {
"buttons" : [ {
"text" : "Submit Form",
"color" : {
"red" : 0.38,
"green" : 0.765,
"blue" : 0.762,
"alpha" : 1.0
},
"onClick" : {
"action" : {
"function" : "https://8f74-38-101-235-211.ngrok.io/landing/process/nda",
"parameters" : [ {
"key" : "action",
"value" : "process/nda"
} ]
}
},
"disabled" : false
} ]
}
} ]
} ]
}
} ]
}}}
And here is a picture of the form on the card:

I'm currently trying to write multiple QueueConfigurations into my CloudFormation template. Each is an SQS queue that is triggered when an object is created to a specified prefix. Here's what I have so far:
{
"Resources": {
"S3Bucket": {
"Type" : "AWS::S3::Bucket",
"Properties" :
"BucketName" : { "Ref" : "paramBucketName" },
"LoggingConfiguration" : {
"DestinationBucketName" : "test-bucket",
"LogFilePrefix" : { "Fn::Join": [ "", [ { "Ref": "paramBucketName" }, "/" ] ] }
},
"NotificationConfiguration" : {
"QueueConfigurations" : [{
"Id" : "1",
"Event" : "s3:ObjectCreated:*",
"Filter" : {
"S3Key" : {
"Rules" : {
"Name" : "prefix",
"Value" : "folder1/"
}
}
},
"Queue" : "arn:aws:sqs:us-east-1:958262988361:interstate-cdc_feeder_prod_hvr_dev"
}],
"QueueConfigurations" : [{
"Id" : "2",
"Event" : "s3:ObjectCreated:*",
"Filter" : {
"S3Key" : {
"Rules" : {
"Name" : "prefix",
"Value" : "folder2/"
}
}
},
"Queue" : "arn:aws:sqs:us-east-1:958262988361:interstate-latency_hvr_dev"
}]
}
}
}
}
}
}
I've encountered the error saying Encountered unsupported property Id. I thought that by defining the ID, I would be able to avoid the Duplicate object key error.
Does anyone know how to create multiple triggers in a single CloudFormation template? Thanks for the help in advance.
It should be structured like the below, There should only be one QueueConfigurations attribute
that contains all queue configurations within it. Also the Id parameter is not a valid property.
{
"Resources": {
"S3Bucket": {
"Type" : "AWS::S3::Bucket",
"Properties" :
"BucketName" : { "Ref" : "paramBucketName" },
"LoggingConfiguration" : {
"DestinationBucketName" : "test-bucket",
"LogFilePrefix" : { "Fn::Join": [ "", [ { "Ref": "paramBucketName" }, "/" ] ] }
},
"NotificationConfiguration" : {
"QueueConfigurations" : [{
"Event" : "s3:ObjectCreated:*",
"Filter" : {
"S3Key" : {
"Rules" : {
"Name" : "prefix",
"Value" : "folder1/"
}
}
},
"Queue" : "arn:aws:sqs:us-east-1:958262988361:interstate-cdc_feeder_prod_hvr_dev"
},
{
"Event" : "s3:ObjectCreated:*",
"Filter" : {
"S3Key" : {
"Rules" : {
"Name" : "prefix",
"Value" : "folder2/"
}
}
},
"Queue" : "arn:aws:sqs:us-east-1:958262988361:interstate-latency_hvr_dev"
}]
}
}
}
}
}
}
There is more information about QueueConfiguration in the documentation.
I am trying to update field value in mongoose.
{
"_id" : ObjectId("5b62c772efedb6bd3f0c983a"),

"title" : "Box",
"id" : "2"
}
],
"comment" : [
"comment4"
],
"recommendation" : ""
}
]
}]
}
Here I want to update a title Fan in image array as table fan.
I tried $set but I don't know how to do for my db structure.
Kindly give some solution to this
**Updated:**
I tried this code:
mongo.inspection.update({"projectID" : mongoose.Types.ObjectId(req.body.project_id) },
{ "$set": {
"inspection_data.$[e1].locationAspects.$[e2].comments.$[e3].images.$[e4].title" : "TableFan"
}},
{ "arrayFilters": [
{ "e1._id": mongoose.Types.ObjectId(req.body.insId)},
{ "e2._id": mongoose.Types.ObjectId(req.body.aspectId)},
{ "e3._id": mongoose.Types.ObjectId(req.body.commentId)},
{ "e4.id": "1" }
]},function(err,response){
if(err){
console.log("error")
}
else{
console.log('Updated')
console.log(response)
}
})
db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } )
Its showing updated but in my db there is no change. Is any mistake I did ?
You can try with arrayFilters in mongodb
var mongoose = require('mongoose')
Temp.update(
{ "_id" : mongoose.Types.ObjectId("5b62c772efedb6bd3f0c983a") },
{ "$set": {
"inspection_data.$[e1].locationAspects.$[e2].comments.$[e3].images.$[e4].title": "TableFan"
}},
{ "arrayFilters": [
{ "e1._id": mongoose.Types.ObjectId("5b62c772fa02622a18655e7b") },
{ "e2._id": mongoose.Types.ObjectId("5b62c772fa02622a18655e80") },
{ "e3._id": mongoose.Types.ObjectId("5b62c772fa02622a18655e81") },
{ "e4.id": "1" }
]}
)
Note: You have to cast _id to ObjectId
I am using Logstash 2.4 to read JSON messages from a Kafka topic and send them to an Elasticsearch Index.
The JSON format is as below --
{
"schema":
{
"type": "struct",
"fields": [
{
"type":"string",
"optional":false,
"field":"reloadID"
},
{
"type":"string",
"optional":false,
"field":"externalAccountID"
},
{
"type":"int64",
"optional":false,
"name":"org.apache.kafka.connect.data.Timestamp",
"version":1,
"field":"reloadDate"
},
{
"type":"int32",
"optional":false,
"field":"reloadAmount"
},
{
"type":"string",
"optional":true,
"field":"reloadChannel"
}
],
"optional":false,
"name":"reload"
},
"payload":
{
"reloadID":"328424295",
"externalAccountID":"9831200013",
"reloadDate":1446242463000,
"reloadAmount":240,
"reloadChannel":"C1"
}
}
Without any filter in my config file, the target documents from the ES index look like below --
{
"_index" : "kafka_reloads",
"_type" : "logs",
"_id" : "AVfcyTU4SyCFNFP2z5-l",
"_score" : 1.0,
"_source" : {
"schema" : {
"type" : "struct",
"fields" : [ {
"type" : "string",
"optional" : false,
"field" : "reloadID"
}, {
"type" : "string",
"optional" : false,
"field" : "externalAccountID"
}, {
"type" : "int64",
"optional" : false,
"name" : "org.apache.kafka.connect.data.Timestamp",
"version" : 1,
"field" : "reloadDate"
}, {
"type" : "int32",
"optional" : false,
"field" : "reloadAmount"
}, {
"type" : "string",
"optional" : true,
"field" : "reloadChannel"
} ],
"optional" : false,
"name" : "reload"
},
"payload" : {
"reloadID" : "155559213",
"externalAccountID" : "9831200014",
"reloadDate" : 1449529746000,
"reloadAmount" : 140,
"reloadChannel" : "C1"
},
"#version" : "1",
"#timestamp" : "2016-10-19T11:56:09.973Z",
}
}
But, I want only the value part of the "payload" field to move to my ES index as the target JSON body. So I tried to use the 'mutate' filter in the config file as below --
input {
kafka {
zk_connect => "zksrv-1:2181,zksrv-2:2181,zksrv-4:2181"
group_id => "logstash"
topic_id => "reload"
consumer_threads => 3
}
}
filter {
mutate {
remove_field => [ "schema","#version","#timestamp" ]
}
}
output {
elasticsearch {
hosts => ["datanode-6:9200","datanode-2:9200"]
index => "kafka_reloads"
}
}
With this filter, the ES documents now look like below --
{
"_index" : "kafka_reloads",
"_type" : "logs",
"_id" : "AVfch0yhSyCFNFP2z59f",
"_score" : 1.0,
"_source" : {
"payload" : {
"reloadID" : "850846698",
"externalAccountID" : "9831200013",
"reloadDate" : 1449356706000,
"reloadAmount" : 30,
"reloadChannel" : "C1"
}
}
}
But actually It should be like below --
{
"_index" : "kafka_reloads",
"_type" : "logs",
"_id" : "AVfch0yhSyCFNFP2z59f",
"_score" : 1.0,
"_source" : {
"reloadID" : "850846698",
"externalAccountID" : "9831200013",
"reloadDate" : 1449356706000,
"reloadAmount" : 30,
"reloadChannel" : "C1"
}
}
Is there a way to do this? Can anyone help me on this?
I also tried the below filter --
filter {
json {
source => "payload"
}
}
But that is giving me errors like --
Error parsing json {:source=>"payload", :raw=>{"reloadID"=>"572584696", "externalAccountID"=>"9831200011", "reloadDate"=>1449093851000, "reloadAmount"=>180, "reloadChannel"=>"C1"}, :exception=>java.lang.ClassCastException: org.jruby.RubyHash cannot be cast to org.jruby.RubyIO, :level=>:warn}
Any help will be much appreciated.
Thanks

You can achieve what you want using the following ruby filter:
ruby {
code => "
event.to_hash.delete_if {|k, v| k != 'payload'}
event.to_hash.update(event['payload'].to_hash)
event.to_hash.delete_if {|k, v| k == 'payload'}
"
}
What it does is:
remove all fields but the payload one
copy all payload inner fields at the root level
delete the payload field itself
You'll end up with what you need.
It's been a while but here there is a valid workaround, hope it would be useful.
json_encode {
source => "json"
target => "json_string"
}
json {
source => "json_string"
}
Im trying to create a 'jsTree' treeview that gets it's data from a .Net webservice.
Everything is working, except for the a-node's href attribute. Whatever I try, it always renders as '#'.
As I understand from the documentation, all attributes in any data object get copied to the a-node.
Below is an example of my current json object. Can anyway figure out why the href attribute isn't copied to the nodes?
[ { "attributes" : { "id" : "rootnode_2",
"rel" : "root2"
},
"children" : [ { "attributes" : { "id" : "childnode_9",
"rel" : "folder"
},
"children" : [ { "attributes" : { "id" : "childnode_23",
"rel" : "folder"
},
"children" : null,
"data" : { "href" : "http://www.google.com",
"title" : "Test_Below_1"
},
"state" : null
} ],
"data" : { "href" : "http://www.google.com",
"title" : "Test_1"
},
"state" : null
},
{ "attributes" : { "id" : "childnode_10",
"rel" : "folder"
},
"children" : [ { "attributes" : { "id" : "childnode_24",
"rel" : "folder"
},
"children" : null,
"data" : { "href" : "http://www.google.com",
"title" : "Test_Below_2"
},
"state" : null
} ],
"data" : { "href" : "http://www.google.com",
"title" : "Test_2"
},
"state" : null
}
],
"data" : { "href" : "http://www.google.com",
"title" : "Glatt"
},
"state" : "closed"
} ]
This is how I initialize the tree;
$("#jstreejson").jstree({
json_data : {
"data": treeObject
},
themes: {
"theme": "apple",
"dots": true,
"icons": true,
"url": "/Scripts/themes/apple/style.css"
},
plugins: ['core', 'themes', 'json', "json_data"]
});
So... I'm not sure that's entirely correct. You can't control the anchor attributes as far as I know, but what you can do add stuff to the attr hash in the json and then use the select_node.jstree event to open the desired link, i.e:
.bind("select_node.jstree", function (e,data) {
var href_address = data.rslt.obj.attr("whatever");
// open desired link
}
