This is my document
{
"name": "andrew",
"b": [{"x":"c1", "y": 0}, {"x":"c2", "y": 0}]
}
I want to find element in the array field "b" and update the entire object. I tried this script but it does not update. Any ideas?
{
"script": "for (item in ctx._source.b) { if (item['x'] == x_id) { item = newobj; } };",
"params": {
"x_id": "c1",
"newobj" : {"x":"c1", "y": 4222}
},
"lang":"groovy"
}
Use this instead:
{
"script": "for (int i=0;i<ctx._source.b.size();i++) { item=ctx._source.b[i]; if (item['x'] == x_id) { ctx._source.b[i] = newobj} };",
"params": {
"x_id": "c1",
"newobj": {
"x": "c1",
"y": 4222
}
},
"lang": "groovy"
}

Can we use string manipulation functions like below in JoltTransformJSON
${BIG:padRight(5, '#')}
Link:
https://jolt-demo.appspot.com/#modify-stringFunctions
Expected Output: BIG##
Like we use
"small_toUpper": "=toUpper(#(1,small))",
"BIG_toLower": "=toLower(#(1,BIG))",
I am trying but it's not giving any error, but not giving the desired result as well. What would be other alternative for this.
Input JSON:
{
"x": [
3,
2,
1,
"go"
],
"small": "small",
"BIG": "BIG",
"people": [
{
"firstName": "Bob",
"lastName": "Smith",
"address": {
"state": null
}
},
{
"firstName": "Sterling",
"lastName": "Archer"
}
]
}
Spec:
[
{
"operation": "modify-default-beta",
"spec": {
"y": "=join(',',#(1,x))",
"z": "=join(' ',#(1,x))",
"small_toUpper": "=toUpper(#(1,small))",
"BIG_toLower": "=toLower(#(1,BIG))",
"BIG_padding": "=padRight(#(5,BIG))"
}
}
]
You can use rightPad function along with modify-xXx-beta (xXx:default or overwrite) transformation such as
[
{
"operation": "modify-default-beta",
"spec": {
"BIG_padding": "=rightPad(#(1,BIG),5,'#')"
}
}
]
I have $balance that is returned from another function like this:
$balance = {
"data": [
{
"name": "ABS",
"y": 1450
},
{
"name": "PBT",
"y": 1200
},
{
"name": "Краситель",
"y": 1000
},
{
"name": "PP",
"y": 750
}
]
}
And I have also collection called $statistics like this:
$statistics = [
{
"name": "ABS",
"data": []
},
{
"name": "PP",
"data": []
},
{
"name": "PBT",
"data": []
},
{
"name": "Краситель",
"data": []
}
]
What I'm trying to do is pushing all y 's of $balance to corresponding $statistics by matching their name.
Here is short description of my code:
foreach ($balance["data"] as $firm){
$statistics->firstWhere('name', $firm->name)['data']->push($firm->y);
}
However, I'm getting Call to a member function push() on null error. Can anyone help me find out the problem
I use following terraform code to get a list of available db resources:
data "alicloud_db_instance_classes" "resources" {
instance_charge_type = "PostPaid"
engine = "PostgreSQL"
engine_version = "10.0"
category = "HighAvailability"
zone_id = "${data.alicloud_zones.rds_zones.ids.0}"
multi_zone = true
output_file = "./classes.txt"
}
And the output file looks like this:
[
{
"instance_class": "pg.x4.large.2",
"storage_range": {
"max": "500",
"min": "250",
"step": "250"
},
"zone_ids": [
{
"id": "cn-shanghai-MAZ1(b,c)",
"sub_zone_ids": [
"cn-shanghai-b",
"cn-shanghai-c"
]
}
]
},
{
"instance_class": "pg.x8.medium.2",
"storage_range": {
"max": "250",
"min": "250",
"step": "0"
},
"zone_ids": [
{
"id": "cn-shanghai-MAZ1(b,c)",
"sub_zone_ids": [
"cn-shanghai-b",
"cn-shanghai-c"
]
}
]
},
{
"instance_class": "rds.pg.c1.xlarge",
"storage_range": {
"max": "2000",
"min": "5",
"step": "5"
},
"zone_ids": [
{
"id": "cn-shanghai-MAZ1(b,c)",
"sub_zone_ids": [
"cn-shanghai-b",
"cn-shanghai-c"
]
}
]
},
{
"instance_class": "rds.pg.s1.small",
"storage_range": {
"max": "2000",
"min": "5",
"step": "5"
},
"zone_ids": [
{
"id": "cn-shanghai-MAZ1(b,c)",
"sub_zone_ids": [
"cn-shanghai-b",
"cn-shanghai-c"
]
}
]
}
]
And I want to get the one that's cheapest.
One way to do so is by sorting with storage-range.min， but how do I sort this list based on 'storage_range.min'?
Or I can filter by 'instance_class', but "alicloud_db_instance_classes" doesn't seem to like filter as it says: Error: data.alicloud_db_instance_classes.resources: : invalid or unknown key: filter
Any ideas?
The sort() function orders lexicographical and you have no simple key here.
You can use filtering with some code like this (v0.12)
locals {
best_db_instance_class_key = "rds.pg.s1.small"
best_db_instance_class = element( alicloud_db_instance_classes.resources, index(alicloud_db_instance_classes.resources.*.instance_class, best_db_instance_class_key) )
}

How to update document with field mapping Object(multi=True),
when a document can have both single (dictionary) and multiple values (list of dictionaries).
Example of documents in the same index:
A single value in items:
{
"title": "Some title",
"items": {
"id": 123,
"key": "foo"
}
}
Multiple values in items:
{
"title": "Some title",
"items": [{
"id": 456,
"key": "foo"
}, {
"id": 789,
"key": "bar"
}]
}
You can try to use the following script.
I intentionally formatted inline attribute to show what's inside.
POST index_name/_update_by_query
{
"search": {
"term": {
"items.key": "foo"
}
},
"script": {
"inline": "
if (ctx._source.items instanceof List) {
for (item in ctx.source.items) {
if (item.key == params.old_value) {
item.key = params.new_value;
break;
}
}
} else {
ctx._source.items.key = params.new_value;
}
",
"params": {"old_value": "foo", "new_value": "bar"},
"lang": "painless'
}
}
And to make it work, replace inline attribute with a single line value.
"inline": "if (ctx._source.items instanceof List) {for (item in ctx.source.items) {if (item.key == params.old_value) {item.key = params.new_value;break;}}} else {ctx._source.items.key = params.new_value;}"
I'm using NVD3 to display of a number of line charts and would like to be able to get the min and max values of the xAxis currently displayed. In this case the xAxis shows time values.
When toggling the visibility of lines in the chart, by clicking the legend label, the date range is changed. I've added an event handler to listen to legendClicks but how do I get my hands on the newly rendered date range?
I ended up using a custom function to find the min/max values of the x axis when clicking the legend. I wrapped the function within a $timeout in order to wait for the digest cycle to be completed to get the proper value, ie:
legend: {
dispatch: {
legendClick: function(e) {
$timeout(function(){
getMinMax();
}, 0);
}
}
},
The getMinMax function is a quick and dirty one and may most likely be done in a more elegantly manner, however it does its job:
var getMinMax = function(){
var maxVal, minVal = null;
for(var i=0;i<$scope.data.length;i++) {
// Only displayed should be considered
if (!$scope.data[i].disabled) {
var tempMinVal = d3.max($scope.data[i].values, function(d) { return d.x;} );
var tempMaxVal = d3.min($scope.data[i].values, function(d) { return d.x;} );
minVal = (!minVal || tempMinVal < minVal) ? tempMinVal : minVal;
maxVal = (!maxVal || tempMaxVal > maxVal) ? tempMaxVal : maxVal;
}
}
return [minVal, maxVal];
};
Will get the min and max from the data in this format:
[
{
"key": "AA",
"values": [
{
"x": 1440712800000,
"y": "6",
"series": 0
},
{

"y": "6",
"series": 0
}
]
},

},

},
{

}
]
},

}
]
},
{
"key": "DD",
"values": [
{
"x": 1443650400000,
"y": "1",
"series": 3
},
{
"x": 1443650400000,
"y": "1",
"series": 3
}
]
},
{
"key": "EE",
"values": [
{

},
{

}
]
As I reached this far the client changed mind and didn't want the functionality that required this solution. Hope it may be of use for someone else.
