"customers": [
{
"id": 123,
"name": "Ed",
"products": [
{
"id": 50,
"prodnm": "xyz",

"id": 60,
"prodnm": "abc",
rate:30,
}
]
}
]
}
iam using rails & want to check whether i m getting proper json response..plz help..

For that you can use this code to get the json from store.
function getJsonOfStore(store){
var datar = new Array();
var jsonDataEncode = "";
var records = store.getRange();
for (var i = 0; i < records.length; i++) {
datar.push(records[i].data);
}
jsonDataEncode = Ext.util.JSON.encode(datar);
return jsonDataEncode;
}
print that json in console then copy that json and past it here, click on format it will show you a formated json.

The best way to check the response is by using Fiddler

SQL Server stored procedure in .NET Core 6 Web API to produce JSON data used in Angular app

I have a SQL Server stored procedure that has an ID parameter and returns a string in JSON format that is needed in the Angular app.
Here is a sample of the JSON needed:
[
{
"type": "date",
"name": "asofdate",
"ui":
{
"label": "As Of Date",
"placeholder": "Enter a date"
},
"validators": { "required": "true" }
},
{
"type": "select",
"name": "scope",
"ui": { "label": "Scope", "placeholder": "Select a scope" },
"validators": { "required": "true" },
"source": [
{ "value": 1, "text": "ABC" },
{ "value": 2, "text": "CDE" },
{ "value": 3, "text": "FGI" }
]
}
]
Here is a what the result of running the stored procedure looks like:
When I run the Web API passing the ID parameter to the stored procedure, I would like to capture the response as a JSON object to be used in the Angular app.
But the Web API is returning this:
[
{
"jsonResponse": "[
{
\"type\":\"date\",
\"name\":\"asofdate\",
\"ui\":{\"label\":\"As Of Date\",\"placeholder\":\"Enter a date\"},
\"validators\":{\"required\":\"true\"}
}
,
{
\"type\":\"select\",
\"name\":\"scope\",
\"ui\":{\"label\":\"Scope\",\"placeholder\":\"Select a scope\"},
\"validators\":{\"required\":\"true\"},
\"source\":[{\"value\":1,\"text\":\"ABC\"},{\"value\":2,\"text\":\"DEF\"},{\"value\":3,\"text\":\"GHI\"}]}
}
]
Is there a way to get the JSON response from the Web API without all the "\" and without:
{
"jsonResponse": "
so that it matches the sample above?
Here is the code from the Web API:
[HttpGet("{ReportID}")]
public async Task<ActionResult<IEnumerable<usp_ReportParameterResult>>> GetReportParameters(int ReportID)
{
if (_context.usp_ReportParameterAsync == null)
{
return NotFound();
}
var op = new OutputParameter<int>();
var JSONresponse = await _context.usp_ReportParameterAsync(ReportID, op);
if (JSONresponse == null)
{
return NotFound();
}
return JSONresponse;
}
The stored procedure uses JSON_QUERY and JSON PATH to create the needed nested arrays.
So, in the angular code I have the following hard-coded:
TESTDATA:any[] = [
{
type:'text',
name:'firstName',
validators:{
required:true
},
ui:{label:'First Name',placeholder:'Enter Your First Name'}
}
,
{
"type":"date",
"name":"asofdate",
"ui":{"label":"****As Of Date","placeholder":"Enter a date","class":["date-picker-wrapper"]},
"validators":{"required":"true"}
}
]
What I need is instead of this data being hrad-coded it is being dynamically generated from a Web API.
The hard-coded data looks like the following from browser debug:
[![enter image description here][2]][2]
From the web api data looks like the following:
It is not an array like the TESTDATA. Is the a way to get response from web api into an array format as required?
Actually, easiest solution was to remove the backlashes in the Angular app by simply doing the following:
for (let item of this.formattedJSON) {
item.ui = JSON.parse(item.ui);
item.validators = JSON.parse(item.validators);
}

How to use nested loops for fetching the data from a rest api in flutter?

I have a order screen where the placed orders and the items that are placed for each order is displayed. I have used a for loop to fetch the orders from the api but in the order json response it also has items parameter inside which there are multiple items. I am not able to figure out how to place another loop in the code to fetch the items list. So please help me with it...
Thank you..
my json response
[
{
"id": 1453,
"total": "407.00",
"line_items": [
{
"id": 34,
"name": "Aloo Chaat Salad",
"product_id": 931,
"quantity": 1,
"total": "90.00",
},
{
"id": 35,
"name": "Aloo Jeera",
"product_id": 1020,
"quantity": 1,
"total": "140.00",
},
{
"id": 36,
"name": "Banana Shake",
"product_id": 963,
"quantity": 1,
"tax_class": "",
"total": "140.00",
}
],
}
]
myModel.dart
class OrderListModel {
final int id;
final String total;
Map line_items = {};
OrderListModel(this.id, this.total, this.line_items);
}
my code for fetching the data
List<OrderListModel> myAllDatas = [];
Future getDatas() async {
String basicAuth = 'Basic ' +
base64.encode(
utf8.encode('${GlobalVar.consumerKey}:${GlobalVar.secretKey}'));
var response = await http
.get("${GlobalVar.url}wp-json/wc/v2/orders?customer=6", headers: {
'Authorization': basicAuth,
'Accept': 'application/json',
});
if (response.statusCode == 200) {
String responseBody = response.body;
var jsonBody = json.decode(responseBody);
for (var data in jsonBody) // loop for fetching the orders
{
myAllDatas.add(new OrderListModel(data['id'], data['total'],
data['line_items'])); // how to place a loop so that i can fetch the items
inside the line_items parameter too?
}
setState(() {});
} else {
print(response.statusCode);
print(response.body);
}
}
when I fetch the items of line_items i just want to fetch their names and seperate them by commas in a row.
Use for loop like this -
for (var data in body) {
List items = data["line_items"];
for (int i = 0; i < items.length; i++) {
int id = items[i]["id"];
String name = items[i]["name"];
}
}

How to access a particular set of keys in array of Json values which i get as response?

For a particular API , I get a response which is similar to the following .
[
{ "name":"Ford", "model":"Mustang" },
{ "name":"BMW", "model": "320" },
{ "name":"Fiat", "model": "500" }
]
I want to store the values for the key 'name' in a separate variable .
Please read the documentation on using JsonPath carefully: https://github.com/intuit/karate#get
Here is an example which works with your data:
* def response =
"""
[
{ "name":"Ford", "model":"Mustang" },
{ "name":"BMW", "model": "320" },
{ "name":"Fiat", "model": "500" }
]
"""
* def names = $[*].name
* match names == ['Ford', 'BMW', 'Fiat']

How to serialize c# object array into json object without an array

I want to use JsonConvert.Serialize in order to serialize a c# array class object into a json non-array object.
public list<employee> employees;
Output:
"{\"employees\":
{\"name\":\"Alex\",\"number\":\"25860340\"},
{\"name\":\"Tom\",\"number\":\"94085345\"}
}"
The format you have asked for in your question would not be valid JSON, because objects are not allowed to follow one another directly unless they are part of an array (see JSON.org). However, you could transform your employee list into a dictionary and serialize that instead, so long as you had a suitable key to use. One idea would be to use the employee number as a key, for example:
var employees = new List<Employee>
{
new Employee { name = "Alex", number = "25860340" },
new Employee { name = "Tom", number = "94085345" }
};
var obj = new
{
employees = employees.ToDictionary(e => e.number)
};
string json = JsonConvert.SerializeObject(obj, Formatting.Indented);
Console.WriteLine(json);
That would give you this output, which is close to what you wanted:
{
"employees": {
"25860340": {
"name": "Alex",
"number": "25860340"
},
"94085345": {
"name": "Tom",
"number": "94085345"
}
}
}
If the employee number isn't actually unique, you could instead use each employee's position in the list as a key like this:
int i = 0;
var obj = new
{
employees = employees.ToDictionary(e => i++)
};
This would give you the following output instead:
{
"employees": {
"0": {
"name": "Alex",
"number": "25860340"
},
"1": {
"name": "Tom",
"number": "94085345"
}
}
}

How to make ember work with Django REST gis

I am currently trying to setup ember to interact with Django's REST Framework using the ember-django-adapter.
This works flawless. But since I started using djangorestframework-gis, ember is not able to process the responses anymore.
I have not found anyone building geoJSON with ember except for: https://gist.github.com/cspanring/5114078 But that does not seem to be the right approach because I do not want to change the data model?
This is the api-response:
{
"type": "FeatureCollection",
"features": [
{
"id": 1,
"type": "Feature",
"geometry": {
"coordinates": [
9.84375,
53.665466308594
],
"type": "Point"
},
"properties": {
"date_created": "2014-10-05T20:08:43.565Z",
"body": "Hi",
"author": 1,
"expired": false,
"anonymous": false,
"input_device": 1,
"image": "",
"lat": 0.0,
"lng": 0.0
}
}
]
}
While ember expects something like:
[{"id":1,
"date_created":"2014-10-05T20:08:43.565Z",
"body":"Hi",
"author":1,
"expired":false,
"anonymous":false,
"input_device":1,
"image":"",
"lat":0,
"lng":0
}
]
My take on this was to write my own Serializer:
import Ember from "ember";
import DS from "ember-data";
export default DS.DjangoRESTSerializer.extend({
extractArray: function(store, type, payload) {
console.log(payload);
//console.log(JSON.stringify(payload));
var features = payload["features"];
var nPayload = [];
for (var i = features.length - 1; i >= 0; i--) {
var message = features[i];
var nmessage = {"id": message.id};
for(var entry in message.properties){
var props = message.properties;
if (message.properties.hasOwnProperty(entry)) {
var obj = {}
nmessage[entry]=props[entry];
}
}
nPayload.push(nmessage);
};
console.log(nPayload); //prints in the format above
this._super(store, type, nPayload);
},
})
But I receive the following error:
The response from a findAll must be an Array, not undefined
What am I missing here? Or is this the wrong approach? Has anyone ever tried to get this to work?
An alternative would be to handle this on the serverside and simply output a regular restframework response and set lat and long in the backend.
This is not a valid answer for the question above. I wanted to share my solution anyways,
just in case anyone ever gets into the same situation:
I now do not return a valid geoJSON, but custom lat, lng values. The following is backend code for django-rest-framework:
Model:
#models/message.py
class Message(models.Model):
def lat(self):
return self.location.coords[1]
def lng(self):
return self.location.coords[0]
And in the serializer:
#message/serializer.py
class MessageSerializer(serializers.ModelSerializer):
lat = serializers.Field(source="lat")
lng = serializers.Field(source="lng")
Ember can easily handle the format.
