I have this REST API that returns tabular data in the following way:
{"data": [{"el1": 8, "el2": 9}, {"el1": 3, "el2": 4}]}
I would like to use el1 and el2 in a Vega-lite chart. How should I refer to the elements in the array?
From the documentation here:
(JSON only) The JSON property containing the desired data. This parameter can be used when the loaded JSON file may have surrounding structure or meta-data. For example
"property": "values.features"
is equivalent to retrieving json.values.features from the loaded JSON object.
It seems that you can try to specify the "property" property (punny, eh) on the format. Something like this:
"data": {
"url": <your url here>,
"format": {
"type": "json",
"property": "data"
},
}
Disclaimer: I haven't actually tested this but it looks to be supported (:

I'm getting data from google sheet in CSV format. But when the sheet has a Hyperlink in its cell, like =Hyperlink("URL", "pretty text"), the google sheet only gives me the pretty text not the link, So my question is how can I get both links & pretty text from google sheet.
Thanks for helping me
You will have to make use of the valueRenderOption parameter when making the spreadsheets.values.get API call.
Assuming your cell looks like this:
You can retrieve the following values using different values for the valueRenderOption parameter as this one will determine how values are rendered in the output.
1. If valueRenderOption is FORMATTED_VALUE (which is the default value when making the API call):
GET https://sheets.googleapis.com/v4/spreadsheets/SPREADSHEET_ID/values/A1?valueRenderOption=FORMATTED_VALUE
Then the response will look like this:
{
"range": "Sheet1!A1",
"majorDimension": "ROWS",
"values": [
[
"pretty text"
]
]
}
2. If valueRenderOption is UNFORMATTED_VALUE:
GET https://sheets.googleapis.com/v4/spreadsheets/SPREADSHEET_ID/values/A1?valueRenderOption=UNFORMATTED_VALUE
Then the response will look like this:
{
"range": "Sheet1!A1",
"majorDimension": "ROWS",
"values": [
[
"pretty text"
]
]
}
3. If valueRenderOption is FORMULA:
GET https://sheets.googleapis.com/v4/spreadsheets/SPREADSHEET_ID/values/A1?valueRenderOption=FORMULA
Then the response will look like this:
{
"range": "Sheet1!A1",
"majorDimension": "ROWS",
"values": [
[
"=HYPERLINK(\"URL\", \"pretty text\")"
]
]
}
Therefore, depending on the exact result you want to achieve, it would be best to use the FORMULA parameter as this will retrieve the formula with its link and value as well. This might require some string processing if you simply want the link and its value.

I don't have any experience with Javascript so I'm reaching out for the community to accomplish the below.
I have a few API calls configured on Zabbix which are working just fine. The thing is, not all of the results within an item is importante for me so I need to grab just what I want out of the array.
I'm using the pre-processing option on Zabbix to grab what I'm after but I can't get the code correct.
For instance, the below is one of the results Zabbix is getting.
[
{
"batteryLife": "15 minutes",
"communityString": "public",
"instanceId": "260596.1",
"instanceName": "UPS-01",
"ipAddress": "10.1.100.44",
"modelNumber": "GXT4-10000RT230",
"name": "UPS-01",
"objectType": "ScUps",
"scName": "pth-pf-04",
"scSerialNumber": 260596,
"serialNumber": "unknown",
"status": "Up",
"statusDescription": "Online",
"type": "Liebert"
}
]
How Can I Use the pre-processing to grab just the "ipAddress" value for instance?
Thanks for the help.

You can avoid JavaScript preprocessing where you can use JSONPath preprocessing, see https://www.zabbix.com/documentation/current/manual/config/items/preprocessing/jsonpath_functionality
In your case:
$[0].ipAddress
A useful tool for JSONPath is http://jsonpath.com/
In case someone have the same doubt as I was having here is how I got it working to return the "ipAdress" value
var json = JSON.parse(value);
return json.ipAddress;
In case there are more than one dictionary inside of an array.
var json = JSON.parse(value);
return json[0].ipAddress;
We have a json schema that includes a field, for which we want to control the value via the schema (rather than having the user specify the value).
We can set a default value - but this is simply overwritten by the formData that the user parses.
Is there a way to "lock" the field value to the default value provided in the schema, ensuring that the formData is updated with the schema-specified value?
{
"meta": {
"title": "SCHEMA REVISION",
"type": "object",
"properties": {
"rev": {
"title": "We want to lock the below default value via the schema",
"type": "string",
"default": "10.00"
}
}
}
}
Sorry, you cannot do this using the schema alone. It's not designed to be used for forms, so it doesn't have that functionality.
It sounds like you want a read-only field. The documentation for react JSON Schema form supports this: https://github.com/mozilla-services/react-jsonschema-form#read-only-fields
The ui:readonly uiSchema directive will mark all child widgets from a
given field as read-only.
Note: the uiSchema is in addition to your JSON Schema.
My use case is this : I have a Parent -> Children -> GrandChildren hierarchy.
I would like to ingest documents as nested and would like to do BlockJoin queries to retrieve all grandchildren of a particular parent, all children of particular parent etc.
I have defined the appropriate fields in the schema (using curl) and copy fields and field-types as required by my application. I have also defined "text" as a copy field for everything as I have to support random searches.
I have defined the document to ingest as follows :
{
"id": "3443",
"path": "1.employee",
"employeeId": 3443,
"employeeName": "Tom",
"employeeCounty": "Maricopa",
"_childDocuments_": [{
"id": "3443.54545454",
"path": "2.employee.assets",
"assetId": 54545454,
"assetName": "Lenovo",
"assetType": "Laptop",
"_childDocuments_": [{
"id": "3443.54545454.5764646",
"path": "3.employee.assets.assetType",
"processorId": 5764646,
"processorType": "Intel core i7"
}]
}]
}
Now when I query using the Admin UI, I am getting the following flattened out object, also block join queries don't work as well :
{
"responseHeader":{
"status":0,
"QTime":0,
"params":{
"q":"*:*",
"_":"1533252181415"}},
"response":{"numFound":1,"start":0,"docs":[
{
"id":"3443",
"employeeId":3443,
"text":["3443",
"Tom",
"Maricopa"],
"employeeName":"Tom",
"employeeCounty":"Maricopa",
"_childDocuments_.id":[3443.54545454,
3443.643534544],
"_childDocuments_.path":["2.employee.assets],
"_childDocuments_.assetId":[54545454,
643534544],
"_childDocuments_.assetName":["Lenovo"],
What am I missing? How can I make Solr process the nested documents like they are supposed to be rather than flattening them out?
Any help is appreciated.
Found the solution. I was using the wrong URL to post.
I was using http://localhost:8983/solr/my-core/update/json/docs
Instead I should just use http://localhost:8983/solr/my-core/update
Because I am already formatting the doc in Solr format and Solr neednt do any special processing to index it.
I'm in the AngularJS environment, and trying to get a jqWidgets TreeGrid working.
I have the dataAdapter all wired up with the Json formatted data, however the grid renders only one row.
I also have a test treeGrid on the same page, and with sample data, which is working fine.
I'm putting the final Json data setting side-by-side to try and determine where I'm going wrong.
I've used this page as a guide to wire up the treegrid settings, etc. http://www.jqwidgets.com/jquery-widgets-documentation/documentation/angularjs/angularjs.htm
Here is the html showing the jqx treegrid directive for the "bad" grid:
<jqx-tree-grid jqx-instance="jqGridHierObj" jqx-settings="vm.jqGridHierSettings"></jqx-tree-grid>
And the "bad" Json data tree settings binded vm.jqGridHierSettings (too large to post inline):
http://www.bobmazzo.com/grid/TreeGrid_Data_Bad.txt
and here is the "good" grid with Employee test data :
HTML:
<jqx-tree-grid jqx-instance="jqGridEmpObj" jqx-settings="vm.jqGridEmpSettings"></jqx-grid>
vm.jqGridEmpSettings Json data :
http://www.bobmazzo.com/grid/TreeGrid_Data_Good.txt
and from my Angular controller code, a snippet of the javascript with Json data bindings :
I need help to figure out why the "bad" grid is not working ! And why it only renders one row, where is should be showing a hierarchy of data.
thanks.

I found the solution. You must define the “children” as an array type in the 'source' object; that is, prior to passing that object into the dataAdapter. See the dataFields property below :
var source = {
dataType: "json",
dataFields: [
{
"name": "id",
"type": "number"
},
{
"name": "field0",
"type": "string"
},
{
"name": "field1",
"type": "number"
},
{
"name": "field2",
"type": "number"
},
{
name: 'children', // MUST DEFINE CHILDREN AS ARRAY TYPE
type: 'array'
},
],
hierarchy: {
root: 'children'
},
id: 'id',
localData: myData
};
var dataAdapter = new $.jqx.dataAdapter(source);
