I have a json file with this structure
"user_data": {
"0": {
"user_name": "LinkedIn",
"type": "textfile"
"id": "543211",
"all_tickets": [
"56788",
"43224",
"56788"
]
};
"1": {
"user_name": "stackoverflow",
"type": "textfile"
"id": "123456",
"all_tickets": [
"98134",
"76372",
"44522"
]
}
}
}
Whenever user inputs the same data, I want to check against the existing one in the json file and if it matches, I want to return the index. How can I get it?
For example, if a user inputs the same keys and values of :
"user_name": "LinkedIn",
"type": "textfile"
"id": "543211",
"all_tickets": [
"56788",
"43224",
"56788"
]
The output should be 0(since that is the index)
I want to print out JSON images as a variable.
This is my local JSON file (JsonData.json):
{
"appetizer": [
{
"num": "appetizer1",
"name": "salad",
"condition": [ "1", "2" ],
"image": "./appetizer/salad.png"
},
{
"num": "appetizer2",
"name": "soup",
"condition": [ "2", "3" ],
"image": "./appetizer/soup.png"
},
…
],
"main": [
{
"num": "main1",
"name": "beef",
"condition": [ "1" ],
"image": "./main/beef.png"
},
{
"num": "main2",
"name": "fish",
"condition": [ "2", "3" ],
"image": "./main/fish.png"
},
…
]
}
I filtered the name when condition="2". (salad,soup,fish)
This is the code for filtering name:
const newArray1 = [...JsonData["apptizer"], ...JsonData["main"]];
const JsonResult = newArray1.filter(item => {
if(item.condition.indexOf("2") !== -1) return item.name;
});
AND I want to get the image when condition="2".
How can I get them? And How can I print out them?
Do I have to use base64? If so, Can you tell me how to use it?
I saw the explanation, but I can't understand it.
And I imported JSON file this way (I've been correctly using it):
var JsonData = require('./JsonData.json');
You can use below code:
let mainObject = JSON.parse(JSON.stringify(data))
let allKeys = Object.keys(mainObject)
let finalObject = []
allKeys.map((value, index) => {
let array = mainObject[value]
array.map((aryObject, aryIndex) => {
let condition = aryObject['condition']
if (condition.includes('2')) {
finalObject.push(aryObject)
}
})
})
alert(JSON.stringify(finalObject))
You can import data in top of screen:
import { data } from './data';
You can add below text in data.js:
export const data = {
"appetizer": [
{
"num": "appetizer1",
"name": "salad",
"condition": ["1"],
"image": "./appetizer/salad.png"
},
{
"num": "appetizer2222",
"name": "soup",
"condition": ["2", "3"],
"image": "./appetizer/soup.png"
},
],
"main": [
{
"num": "main1",
"name": "beef",
"condition": ["1"],
"image": "./main/beef.png"
},
{
"num": "main2",
"name": "fish",
"condition": ["21", "3"],
"image": "./main/fish.png"
},
]
}
You can use Object#values to get the arrays corresponding to appetizer and main and then Array#flat to extract the nested objects into a transformed array. Then use the Array#filter (which you are already using) to filter out only the required objects based on your condition and then Array#map to get the name and image values out of every filtered object into an array of objects.
Please consider following snippts
const jsonData = {"appetizer":[{"num":"appetizer1","name":"salad","condition":["1","2"],"image":"./appetizer/salad.png"},{"num":"appetizer2","name":"soup","condition":["2","3"],"image":"./appetizer/soup.png"}],"main":[{"num":"main1","name":"beef","condition":["1"],"image":"./main/beef.png"},{"num":"main2","name":"fish","condition":["2","3"],"image":"./main/fish.png"}]};
const filteredValues = Object.values(jsonData)
.flat()
.filter(o => o.condition.includes('2'))
.map(({name, image}) => ({ name, image }));
console.log(filteredValues);
The output of the above code will be an array of objects having the following structure
[{
"name": SOME_NAME,
"image": SOME_PATH
},
{
"name": SOME_NAME,
"image": SOME_PATH
},
...
]
You can use the above array to retrieve your image path and display it accordingly.
I think you shouldn't be worried about base64 as images are stored locally and path will be sufficient to display the image.
Hope this will help!!!
Side Note: You can avoid the Array#flat part as you are already doing it manually [...JsonData["apptizer"], ...JsonData["main"]] but flat will be handy in case there are more keys in jsonData that need to be considered.
I have a variable which is constructed as follows extracting data using Spark SQL:
{
"resourceType" : "Test1",
"count" : 10,
"entry": [{
"id": "112",
"gender": "female",
"birthDate": 1213999
}, {
"id": "urn:uuid:002e27cf-3cae-4393-89c5-1b78050d9428",
"resourceType": "Encounter"
}]
}
I want the output in the following format:
{
"resourceType" : "Test1",
"count" : 10,
"entry" :[
"resource" :{
"id": "112",
"gender": "female",
"birthDate": 1213999
},
"resource" :{
"id": "urn:uuid:002e27cf-3cae-4393-89c5-1b78050d9428",
"resourceType": "Encounter"
}]
}
I am basically new to Scala :), would need help in this.
EDIT: Adding the scala code to create the JSON:
val bundle = endresult.groupBy("id").agg(count("*") as "total",collect_list("resource") as "entry").
withColumn("resourceType", lit("Bundle")).
drop("id").
select(to_json(struct("resourceType","entry"))).
map(row => row.getString(0).
replace("\"entry\":[\"{", "\"entry\":[{").
replace("}\"]}","}]}"). // Should be at the end of the string ONLY (we might switch to regex instead
replace("}\",\"{","},{")
replace("\\\"", "\"")
)
Need a JSON path expression for below JSON. I wanted to extract "Id" for each specific "name"
For Example: I need to extract "Id" : "3" for "name" : "XYZ" .
I tried a JSON path expression as $..Id which given output as:
[
"1",
"2",
"3"
]
But I needed an Id specific to "name": "XYZ"`
[
{
"primary":{
"name":"ABC"
},
"Id":"1"
},
{
"primary":{
"name":"PQR"
},
"Id":"2"
},
{
"primary":{
"name":"XYZ"
},
"Id":"3"
}
]
Able to resolve this by below expression
$..[?(#.primary.name == 'XYZ')].Id
I'm having a json file as :-
{
VALUES: [
{
"UTAGID": "SYSTEM_CHILLER1",
"tagName": "P1",
"tagValue": "10",
"tagTime": "2015-07-23T14:29:30.731Z",
"tagQuality": "128"
},
{
"UTAGID": "SYSTEM_CHILLER1",
"tagName": "P1",
"tagValue": "10",
"tagTime": "2015-07-23T14:29:30.731Z",
"tagQuality": "128"
},
{
"UTAGID": "SYSTEM_CHILLER1",
"tagName": "P1",
"tagValue": "10",
"tagTime": "2015-07-23T14:29:30.731Z",
"tagQuality": "128"
}
]
};
where each record is not on a single line.I'm able to retrieve values from a hive table based on this if each record appears on a single line else it shows null values.
What could be the reason?how do I insert new line feed after each record?
Thanks
