I use a 'New update timeseries' widget to update a Temperature value.
How can I extract the Temperature value from the Timeseries update message?
f.e. I want to create a new value: msg.temperature2 = msg.temperature + 5
In the rule chain I intercept the update timeseries message with a "Timeseries update
Message:
{
"timeseries": [{
"ts": 1651399784349,
"values": {
"Temperature": 30
}
}]
}

Rule chain
Transformation script-test script function
It's just a matter of referencing the value correctly. See below for example.
let msg = {
"timeseries": [{
"ts": 1234,
"values":{
"Temperature": 30
}
}]
}
// The code
var newMsg = msg
newMsg.timeseries[0].values.Temperature2 = newMsg.timeseries[0].values.Temperature + 5
// Remove log, uncomment return
console.log({ "msg": newMsg, "metadata": {} })
//return { "msg": msg, "metadata": {} }

I need to deserialize ( and later on serialize ) a piece of data that has this type of a structure :
{
"type": "TypeApplication",
"val": {
"con": {
"type": "TypeConstructor",
"val": [
"Builtin",
"Record"
]
},
"arg": {
"type": "RowCons",
"val": {
"label": "953e3dd6-826e-1985-cb99-fd4ed4da754e",
"type": {
"type": "TypeApplication",
"val": {
"con": {
"type": "TypeConstructor",
"val": [
"Builtin",
"List"
]
},
"arg": {
"type": "Element",
"meta": {
"multiLine": true
}
}
},
"system": {
"label": "nullam-senectus-port - Text",
"isBindable": true,
"defaultValue": [
{
"id": "4a05486f-f24d-45f8-ae13-ab05f824d74d",
"type": "String",
"pluginType": "Basic",
"data": {
"value": "Nullam senectus porttitor in eget. Eget rutrum leo interdum."
},
"children": [],
"text": true
}
],
"isUnlinked": false,
"isDefault": false
}
},
"tail": {
"type": "RowCons",
"val": {
"label": "94f603df-d585-b45a-4252-9ec77cf5b13c",
"type": {
"type": "TypeApplication",
"val": {
"con": {
"type": "TypeConstructor",
"val": [
"Builtin",
"List"
]
},
"arg": {
"type": "Element",
"meta": {
"multiLine": true
}
}
},
"system": {
"label": "best-services - Text",
"isBindable": true,
"defaultValue": [
{
"id": "6265ca45-3f69-4844-97e2-c05bbfb9fee5",
"type": "String",
"pluginType": "Basic",
"data": {
"value": "Best Services"
},
"children": [],
"text": true
}
]
}
},
"tail": {
"type": "RowEmpty"
}
}
}
}
}
}
}
I do not know what this data exactly is, but I know this is trying to represent a function/element that takes in values and defaults for those values as parameters/properties.
I want to deserialize it using serde and consequently serialize it too.
I have so far been able to write something that sort of works but not really :
#[skip_serializing_none]
#[derive(Deserialize, Serialize, Debug, Clone)]
#[serde(tag = "type", content = "val")]
pub enum WebflowPropDataType {
TypeApplication {
con: Box<WebflowPropDataType>, // Normally Passes the Type Constructor
arg: Box<WebflowPropDataType>, // Normally Passes the Row Constructor
},
TypeConstructor(Vec<String>), // Stores Value of TypeConstructor
RowCons {
label: String, // Stores the label of the Row
#[serde(rename = "type")]
row_con_type: Box<WebflowPropDataType>, // Stores the type of the Row
tail: Box<WebflowPropDataType>,
},
RowEmpty, // For Ending the recursive usage of rowConstructor
}
#[skip_serializing_none]
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct WebflowRowConDataType {
#[serde(rename = "type")]
val_type: String, // TypeApplication
val: Box<WebflowPropDataType>,
}
This works for a structure like this :
{
"type": "TypeApplication",
"val":{
"con": {
"type": "TypeConstructor",
"val": []
},
"arg": {
"type": "RowEmpty"
}
}
}
but would fail if I try to work with initial example. I know this may be due to the lack of a proper arg type or maybe even the TypeApplication Enum hand is malformed.
I do see that a adjancent typing solution would be enough for most of the times but there are cases as seen in the example structure that there is a third value called system and I am unable to determine what type of approach would help me achieve this type of outcome.
How should I approach this problem in order to generate this type of code.
I am not asking anyone to write me a solution but to give me suggestion as to what my approach should be? Whether you'd know what type of data this is/how to generated this , or even if there are some other library I should look into to manipulate this type of data or maybe look at other approaches.
PS : - My end goal is to be able to generate / serialize this type of JSON code from already contained knowledge of properties and default values of a function/object.
Here are my recommendations:
Use just #[serde(tag = "type")] instead of #[serde(tag = "type", content = "val")]. You will have to handle val manually (extracting the current enum members into separate structs), but this allows you to also handle TypeApplication.system and Element.meta.
This also has the small benefit of reducing the amount of Boxes involved.
Consider whether all of the different cases in WebflowPropDataType can actually occur everywhere it's used. If not (maybe Element can only happen under TypeApplication.val.arg), then you may want to split the enum into multiple so that this is reflected in the type system.
Example for #1:
use serde::{Serialize, Deserialize};
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct TypeApplicationVal {
con: WebflowPropDataType, // Normally Passes the Type Constructor
arg: WebflowPropDataType, // Normally Passes the Row Constructor
}
// #[skip_serializing_none]
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct TypeApplicationSystem {
label: String,
#[serde(rename = "isBindable")]
is_bindable: bool,
// TODO: defaultValue
#[serde(rename = "isUnlinked")]
#[serde(skip_serializing_if = "Option::is_none")]
is_unlinked: Option<bool>,
#[serde(rename = "isDefault")]
#[serde(skip_serializing_if = "Option::is_none")]
is_default: Option<bool>,
}
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct RowConsVal {
label: String, // Stores the label of the Row
#[serde(rename = "type")]
typ: WebflowPropDataType, // Stores the type of the Row
tail: WebflowPropDataType,
}
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct ElementMeta {
#[serde(rename = "multiLine")]
multi_line: bool,
}
#[derive(Deserialize, Serialize, Debug, Clone)]
#[serde(tag = "type")]
pub enum WebflowPropDataType {
TypeApplication {
val: Box<TypeApplicationVal>,
#[serde(skip_serializing_if = "Option::is_none")]
system: Option<TypeApplicationSystem>,
},
TypeConstructor {
val: Vec<String> // Stores Value of TypeConstructor
},
RowCons {
val: Box<RowConsVal>,
},
Element {
meta: ElementMeta,
},
RowEmpty, // For Ending the recursive usage of rowConstructor
}

I try to fill a treelist with remote data via a ajax proxy but the treelist shows only the first level and try to reload the sub levels even though the json response contain a complete tree structure. Fiddle link: https://fiddle.sencha.com/#view/editor&fiddle/33u9
When i try to expand the node 'SUB a' (or set the expanded property to true) the store trys to reload the node.
Why is the tree structure from the json response not honored?
Thanks in Advance.
The backend response looks like:
{
"data": {
"root": [
{
"leaf": true,
"text": "Server"
},
{
"leaf": true,
"text": "Storage"
},
{
"text": "SUB a"
"children": [
{
"leaf": true,
"text": "Modul A - 1"
},
{
"leaf": true,
"text": "Modul A - 2"
}
],
},
{
"leaf": true,
"text": "Modul B"
}
]
},
"success": true
}
The used reader config is
reader: {
type: 'json',
rootProperty: 'data.root',
successProperty: 'data.success',
},
After playing around i use the following workaround:
getNavigation: function() {
var me = this,
tree = me.getView().down('navigationtree'),
store = tree.getStore(),
node = store.getRoot();
Ext.Ajax.request({
url: '/getnav',
method: 'POST',
success: function(response) {
var obj = Ext.decode(response.responseText),
childs = obj.data.root;
tree.suspendEvents();
node.removeAll();
childs.forEach(function(item) {
node.appendChild(item);
});
tree.resumeEvents();
},
failure: function(response) {
//debugger;
console.log('server-side failure with status code ' + response.status);
}
}).then(function() {
//debugger;
}
);
}
The funny things is that only the first level of the tree has to be added all following sub-levels are added automaticaly.
I have some data coming in random order and would like to convert into into a specific order for Highchart column ranges. Any insight on doing this effectively and insight would help
Also regardless of order of input data I always want to show chart in Apple Orange Banana order with their correct representation
I have tried using maps,sets,array in ruby and have something working which is super brittle and not the most effective.
headers = Array.wrap(raw_data.dig('data', 'dimensions', 'axes', 'headers'))
values = Array.wrap(raw_data.dig('data', 'values', 'c')).map(&:to_f)
labels = headers.map { |header| Array.wrap(header['label']) }
data = values.each_slice(2)
This is the weight of the fruits LOW is lowest weight and HIGH is highest weight. The problem is order of data is ordered by weight so I cant just slice consecutive values of array.

You need to preprocess your data to the format required by Highcharts:
var json = {...}
var series = {
name: 'Weight',
data: []
},
i,
header1,
header2,
value,
indexOf,
point,
categories = [];
for (i = 0; i < json.data.values.c.length; i++) {
labels = json.data.dimensions.axes.headers[i].label;
header1 = labels[0].toLowerCase(),
header2 = labels[1].toLowerCase(),
value = json.data.values.c[i];
indexOf = categories.indexOf(header1);
if (indexOf !== -1) {
series.data[indexOf][header2] = Number(value);
} else {
categories.push(header1);
series.data.push({
[header2]: Number(value),
x: series.data.length
});
}
}
Highcharts.chart('container', {
...,
series: [series]
});

I am unable to insert multiple rows in database using Post method in MVC web API. I have written code for it but when i am testing by inserting multiple rows through postman it is giving error. At line first the variable "delegatetable" shows null due to which error is coming. i am not doing database connection through entity framework, i have created a DelegateTable class.
public HttpResponseMessage Post(List<DelegateTable> delegatetable)
{
try
{
using (var delegateContext = new ShowContext())
{
foreach (DelegateTable item in delegatetable)
{
DelegateTable delegates = new DelegateTable();
delegates.Salutation__c = item.Salutation__c;

delegates.Category__c = item.Category__c;
delegates.Conference_Type__c = item.Conference_Type__c;
delegates.Conference_Selection__c = item.Conference_Selection__c;
delegates.Payment_Statuss__c = item.Payment_Statuss__c;
delegates.Barcode__c = item.Barcode__c;
delegateContext.SaveChanges();
}
var message = Request.CreateResponse(HttpStatusCode.Created, delegatetable);
message.Headers.Location = new Uri(Request.RequestUri.ToString());
return message;

You may try to reformat your payload as a JSON array, as the problem might be that the payload cannot be converted to a List.
Try this:
{
"delegates" :
[
{
"attributes": ..., ...
},
{ "attributes": ..., ...
},
...
]
}
I'm attempting to loop through a JSON array sending data to a struct.
Here's my code that uses SwiftyJSON to return a JSON object:
performAPICall() {
json in
if(json != nil){
print("Here is the JSON:")
print(json["content"]["clients"])
let clients = json["content"]["clients"]
for client in clients {
var thisClient = Client()
thisClient.id = client["id"].string
thisClient.desc = client["desc"].string
thisClient.name = client["name"].string
self.clientArray.append(thisClient)
}
self.tableView.reloadData()
} else {
print("Something went very wrong..,")
}
}
I'm not quite sure why I'm getting "has no subscript" errors on the three strings.
Any help appreciated, thanks.
EDIT: Here's a sample of the JSON
{
"content": {
"clients": [{
"group": "client",
"id": "group_8oefXvIRV4",
"name": "John Doe",
"desc": "John's group."
}, {
"group": "client",
"id": "group_hVqIc1eEsZ",
"name": "Demo Client One",
"desc": "Demo Client One's description! "
}, {
"group": "client",
"id": "group_Yb0vvlscci",
"name": "Demo Client Two",
"desc": "This is Demo Client Two's group"
}]
}
}
You should use array method. Thus, your line
let clients = json["content"]["clients"]
should use array (and unwrap it safely):
guard let clients = json["content"]["clients"].array else {
print("didn't find content/clients")
return
}
// proceed with `for` loop here
