I have a list of sObjects and I'd like to convert all the sObject fields to a string. For instance (this is the print out from a SOQL query),
Custom_sobj__c{
"serId": 5,
"value": {
"Id": "a0FJ0000005zIbwMAE",
"Contact__r": {
"serId": 6,
"value": {
"Name": "Bob Bobenson",
"Owner": {
"serRefId": 4
},
"Rule_Class__c": "Class III - Quote\/De (2 more) ...",
"OwnerId": "005d000000450RiAAI",
"Id": "003J0000016ZjuCIAS"
}
},
"Contact__c": "003J0000016ZjuCIAS"
}
}
And I have a list of these objects. I'd like to convert it all to string, so it looks something like this:
...'sobjInstance3{"serid";5,"value":...}','sobjInstance4{"serid";5,"value":...}',...
I have a for loop iterate through the list,
String strSobjects = ' ';
for(Custom_sobj__c obj : sobjList){
strSobjects = strSobjects + ','+String.valueOf(obj);
}
but this only returns the "ID" and "Contact__c". The string is getting the "Name" or "Rule_Class_c" fields.
How can I grab the rest of the data?
The System.JSON method should do the trick: https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_methods_system_json_overview.htm
Something like:
String strSobjects = ' ';
for(Custom_sobj__c obj : sobjList){
strSobjects = strSobjects + ','+JSON.Serialize(obj);
}

I have an State varaible with array of objects like this.
type State = {
Dp: ArrayDataProvider<string, Message>;
};
Inside Dp i will have data which will hold the data in the form of array like this.
[{
"id": 1,
"name": "January",
"abc": abc,
"xyz": xyz
}, {
"id": 2,
"name": "February",
"abc": abc,
"xyz": xyz
}]
I want to replace the object which is having id 2 with the different object and i want to have my object like this .
[{
"id": 1,
"name": "January",
"abc": abc,
"xyz": xyz
}, {
"id": 2,
"name": "New month",
"abc": 1234abc,
"xyz": someVlaue
}]
how to do it in efficient way with typescript in react.
I have done something like this but not working
const data = this.state.Dp?.data.slice();
const index = data.findIndex(currentItem => {
return currentItem.id === updateData[0].id;
});
data[index] = updateData;
this.state.Dp.data = data;
this.setState({ Dp: this.state.Dp });
I use map to do this:
const data = this.state.Dp?.data.map(currentItem => {
return currentItem.id === updatedItem.id ? updatedItem : currentItem;
})
map creates a new array with the items from the previous array, but it gives you an opportunity to make adjustments to the items in the new array as it iterates through them. In my example, I'm checking the id of the item to see if it's the one you want to update, and swapping in your updatedItem if the ids match.
I'm not sure about the TypeScript part, to be honest. I haven't worked with it yet.
Note - I'm not sure what form your updateData is in, so you might have to adjust that. It seems like you want it to be an object, but in one of your lines you're treating it like an array.
Use findIndex to find index of the object where id is equal 2, then replace new object to that place.
let tempArray = [...array];
const index = tempArray.findIndex((element) => element.id === 2);
tempArray[index] = {
id: 2,
name: "New month",
abc: "1234abc",
xyz: "someVlaue"
};
setArray(tempArray);
I'm trying to parse a JSON response from an API and store the data to DATA CLASS and sending the data to recycler adapter as ArrayList.
The JSON Array has another array of objects inside, and I'm not able to find a way to properly parse that JSON response.
Here is my data class:
data class OrderDetails (
val orderId: String, // order_id value from json object goes here //
val restaurantName: String, // restaurant_name value from json object goes here //
val totalCost: String, // total_cost value from json object goes here //
val orderDate: String, // order_placed_at value from json object goes here //
val orderFoodDetails: String // food_items value in json response is an array and i'm stuck here //
)
Here is my Kotlin code:
try {
val data = it.getJSONObject("data")
val success = data.getBoolean("success")
if (success) {
val arrayData = data.getJSONArray("data")
for (i in 0 until arrayData.length()) {
val orderJsonObject = arrayData.getJSONObject(i)
val orderObject = OrderDetails(
orderJsonObject.getString("order_id"),
orderJsonObject.getString("restaurant_name"),
orderJsonObject.getString("total_cost"),
orderJsonObject.getString("order_placed_at"),
orderJsonObject.getJSONArray("food_items").toString() // getting array and storing as a string
)
orderList.add(orderObject)
for (orders in orderList) {
val foodData = orders.orderFoodDetails
val jsonFood = JSONArray(foodData)
for (j in 0 until jsonFood.length()) {
val foodJsonObject = jsonFood.getJSONObject(j)
val foodObject = OrderFoodDetails(
foodJsonObject.getString("food_item_id"),
foodJsonObject.getString("name"),
foodJsonObject.getString("cost")
)
ordersFood.add(foodObject)
}
}
}
Here is the Json response:
{
"data": {
"success": true,
"data": [
{
"order_id": "17790",
"restaurant_name": "Rotten Tomatoes",
"total_cost": "280",
"order_placed_at": "02-11-20 19:00:54",
"food_items": [
{
"food_item_id": "156",
"name": "Rotten Bhajiya",
"cost": "100"
},
{
"food_item_id": "155",
"name": "Rotten Salad",
"cost": "100"
},
{
"food_item_id": "154",
"name": "Rotten Soup",
"cost": "80"
}
]
},

do you tried to use GSON or Moshy lib ?
This case will be easier solved with one of this :)
If you don't want to use one of them, just try to replace your for cycle to map or for each, to make it more readable. Looks like you make it right, but can you check the result of try catch block please?
While updating a doc (using update API), I need to extract a field of last entered element of an array, and then use it while adding a new element to the same array.
For example:
{
"_id": "guid",
"timestamp": "time",
"conversation": [
{
"previousTopic": "A",
"currentTopic": "B",
"score": 80
},
{
"previousTopic": "B",
"currentTopic": "C",
"score": 85
}
]
}
Now, while inserting a new element to this array using the update API, first extract the "currentTopic" field of the last element (which is C in this case) and then insert this as "previousTopic" of the next element.
I know how to use basic update API which would insert a new element to the array of the document:
POST test/_doc/{doc_id}/_update
{
"script" : {
"source": "ctx._source.communication.add(params.newcom)",
"lang": "painless",
"params" : {
"newcomm" : {
"previousTopic": {extracted value will go here}
"currentTopic" : "D"
"score" : 89 }
}
}
}
I was able to do this flawlessly using painless scripting.
POST test/_doc/nbsadmnsabdmas/_update
{
"script" : {
"lang": "painless",
"source" :
"""
// find the length of array
def count = ctx._source.conversation.length;
// get to the last element and extract
def temp = ctx._source.conversation[count-1].currentTopic;
// add a new element to the array
ctx._source.communication.add(['previousTopic':temp,'currentTopic':'D',
'score':90]);
"""
}
}
Im trying to compare two specific bits of information. One is in the form of a as3 string the other is in the form of a Json array.
The Json array shows customer data from a shop website. What i want to do is have as3 compare the string(i.e a customer name) with the data , and when it has found the matching name, only trace that customers specific information.
Im amusing id have to use a loop for the comparison , but im having trouble getting my head around how to convert the Json into specific junks that can then be compared individually with a string. Any help would be perfect.
Thanks
Be aware that JSON is just a standard AS3 object. There's no magic going on here; loop through it as you would any other structure and run your comparisons as usual.
Solution
var jsonObj:Object = {
"customers": [
{
"id": "04aa1ab3-521b-11e3-a29a-bc305bf5da20",
"name": "fake name",
"customer_code": "00000002",
"customer_group_id": "6012cd22-5166-11e3-a29a-bc305bf5da20",
"customer_group_name": "All Customers",
"first_name": "test",
"last_name": "test",
"company_name": "",
"email": "testest#yahoo.com"
}
]
}
var myString:String = "fake name";
for (var k:String in jsonObj.customers[0]) {
var v:String = jsonObj.customers[0][k];
if (v == myString) {
trace(myString + "'s email is " + jsonObj.customers[0].email)
}
}
Use a Dictionary Object to store customer objects using their unique names (or ids ) as reference;
You certainly do not want to write unnecessary loop search for a customer in question.
Solution.
var jsonObj:Object = {
"customers": [
{
"id": "04aa1ab3-521b-11e3-a29a-bc305bf5da20",
"name": "fake name",
"customer_code": "00000002",
"customer_group_id": "6012cd22-5166-11e3-a29a-bc305bf5da20",
"customer_group_name": "All Customers",
"first_name": "test",
"last_name": "test",
"company_name": "",
"email": "testest#yahoo.com"
}
]
}
//Dictionary Object to store customers
var customers:Dictionary=new Dictionary();
//customer object in the json
var customer:Object;
//loop json object to retrieve customers and
//store them in Dictionary using either unique name or id
for each(customer in jsonObj)
customers[customer.name]=customer;
//retrieve customer in question
function getCustomer(id:String):Object
{
return customers[id] as Object;
}
What is the root property value if I get a Json like that:
{
"status": {
"status": 0,
"msg": "Ok",
"protocolversion": "extjs.json"
},
"value": {
"table": [
[
"admin",
"Administrator",
""
],
[
"test",
"Test",
""
]
],
"total": 2
}
}
The data will be displayed in a gridpanel, 1 row is admin, 1 row is test, etc.
Tried:
value, value.table
How to get this to work?
value.table is correct for the root property, but you are using a json format that I don't think Ext is set up to handle by default. It has a reader for json that is used for an array of objects, not for an nested arrays of field values with no object mapping information.
If you have to use that format, you will either need to create your own readers/writers or just use Ext.Ajax.request(), and in the callback, parse the nested array into objects. Something like:
Ext.Ajax.request({
url: 'path.com/to/content',
success: function (response, operation) {
var data = Ext.JSON.decode(response.responseText);
var fields = data.value.table;
var records = [];
Ext.Array.each(fields, function (fieldArray, fieldIndex) {
Ext.Array.each(fieldArray, function(fieldValue, valueIndex) {
//Create record object if it doesn't exist
var record = records[valueIndex] || {};
//Create a switch statement based on the array index to set fields
switch(fieldIndex) {
case 0:
record.User_id = fieldValue;
break;
case 1:
record.Username = fieldValue;
break;
}
});
});
//Add the objects to the empty store
store.add(records);
}
});
That's not a production solution by any means since it doesn't handle that empty string at the end of your list or the case that you get a jagged array of arrays per field which I can't imagine what to do with. If it's within your control or influence, I would suggest using a format more like what Ext suggests so you can use the built in json proxy/reader/writer or go crazy with it and implement ext's remote procedure call format:
{
"success": true,
"message": "Success",
"data": [
{
"User_id": "admin",
"Username": "Administrator"
}, {
"User_id": "admin",
"Username": "Administrator"
}
]
}
In above example "value" is root property. But for JSON reader it's a property name (or a dot-separated list of property names if the root is nested).
so you can assign into your field you need following.
fields:['table.admin','table.test']
