Sorry for the newbie question. Learning Apex here. Been working on an issue for several hours and can't seem to needle it out.
I have a JSON that I need converted to a List... the JSON is retrieved via an API. The code is pretty simple, it is only a couple of lines.
The JSON looks like this:
{"id":1,"abbreviation":"ATL","city":"Atlanta","conference":"East","division":"Southeast","full_name":"Atlanta Hawks","name":"Hawks"}
And the code I am told to use to retrieve it looks like this:
Map<String, Object> resultsMap = (Map<String, Object>) JSON.deserializeUntyped(results.getBody());
Based on the JSON provided, there does not appear to be a MAP key being assigned, so I have no idea how to get it so that I may assign it to a List...
I've already tried assigning it directly to a List, but I didn't get much success there either.
I've tried this already:
List<Object> other = (List<Object>) results.get('');
I've also tried this:
List<Object> other = (List<Object>) results.keySet()[0];
I'm sure it is something simple. Any help would be appreciated.
Thanks
You cant convert the map to a list without an id. Alternatively why to convert it to List. Use the map itself. Below is a code example of how you can use it using your JSON response. For example, I want to insert this JSON response into the contact record, so I can map it using the MAP itself.:
#RestResource(urlMapping='/URIId/*')
global class OwneriCRM {
#HttpPut
global static String UpdateOwnerinfo(){
RestRequest req= RestContext.request;
RestResponse res= RestContext.response;
res.addHeader('Content-type','application/JSON');
Map<String,Object> responseresult=new Map<String,Object>();
Map<String,Object> results= (Map<String,Object>)JSON.deserializeUntyped(req.requestBody.toString());
List<contact> insertList = new List<contact>();
for (String key : results.keySet()){
System.debug(results.get(key));
contact c= new contact();
c.ContactField__C = results.get(id);
c.ContactField1__C = results.get(city);
c.ContactField2__C = results.get(conference);
c.ContactField3__C = results.get(division);
c.ContactField3__C = results.get(full_name);
c.ContactField3__C = results.get(name);
insertList.add(c);
}
if(!insertList.Isempty()){
update insertList;
}
Question can be disregarded. Not sure if there is a way to withdraw the question.
Question was based on the fact that previous APIs had been sent in the following format:
{"data": {"more stuff": "stuff"} }
And the map key was 'data' with a list. In this scenario, the whole API was a list and the keys to the map were set in place with the actual values instead.

I have record type "XYZ" which has field called "award area" which is of type list/record. "award area" is of type custom list and is a drop down control.
Using Suitetalk how can I retrieve those values from that drop down?
Thank you
I think something like this should work. It's for translating the results from the internalId's returned into the actual text type, you maybe be able to leverage it in another way. Maybe you could create a lookup list with something like this(C#):
public Dictionary<string, Dictionary<long, string>> getCustomFieldLists()
{
return
nsService.search(new CustomListSearch())
.recordList.Select(a => (CustomList) a)
.ToDictionary(a => a.name,
a => a.customValueList.customValue
.ToDictionary(b => b.valueId, c => c.value));
}
var valueLookup = getCustomFieldLists()["award area"];
Here's how I did it for myself, because I was irritated with the fact the NetSuite doesn't just provide us an easy way to access these. And I wanted the following data for reference:
The Internal ID of the Custom List
The Name of the Custom List
The Internal ID of the Custom List Item
The name Value of the Custom List Item
I wanted/needed access to all of those things, and I wanted to be able to obtain the name Value of the Custom List Item by just providing the Internal ID of the Custom List and the Internal ID of the Custom List Item. So, in my homemade integration client, similar to David Rogers' answer, but without all the fancy Linq, I figured out that the best solution was a Dictionary>>.
This way, for the outer Dictionary, I could set the key to the internal IDs of the Custom Lists, and for the inner Dictionary I could set the key to the internal IDs of the Custom List Items themselves. Then, I would get the name of the Custom List for "free" as the beginning part of the Tuple, and the actual name Value for "free" as the value of the internal Dictionary.
Below is my method code to generate this object:
/// <summary>
/// Gets the collection of all custom lists, and places it in the public CustomListEntries object
/// </summary>
/// <returns></returns>
private Dictionary<string, Tuple<string, Dictionary<long, string>>> GetCustomLists()
{
Dictionary<string, Tuple<string, Dictionary<long, string>>> customListEntries = new Dictionary<string, Tuple<string, Dictionary<long, string>>>();
SearchPreferences sp = SuiteTalkService.searchPreferences; //Store search preferences to reset back later, just need body fields this one time
SuiteTalkService.searchPreferences = new SearchPreferences() { bodyFieldsOnly = false };
SearchResult sr = SuiteTalkService.search(new CustomListSearch());
SuiteTalkService.searchPreferences = sp; //Restore search preferences
foreach (CustomList cl in sr.recordList)
{
Dictionary<long, string> customListItems = new Dictionary<long, string>();
if (cl.customValueList == null) continue;
foreach (CustomListCustomValue clcv in cl.customValueList.customValue)
{
customListItems.Add(clcv.valueId, clcv.value);
}
customListEntries.Add(cl.internalId, new Tuple<string, Dictionary<long, string>>(cl.name, customListItems));
}
return customListEntries;
}
Then, in the constructors of my Integration class, I can set my object to the return result:
public Dictionary<string, Tuple<string, Dictionary<long, string>>> CustomListEntries = GetCustomLists();
And finally, whenever I need access TO those values, since I set all of this up ahead of time, I can do the following:
dr[Class] = SuiteTalkIntegrator.CustomListEntries[lorr.typeId].Item2[long.Parse(lorr.internalId)];
In this case above, my "lorr" object is a ListOrRecordRef object that I obtained from the SearchColumnSelectCustomField.searchValue from the search results of a SavedSearch. I don't know if this will work for anyone else that finds this code, but since I was frustrated in finding an easy answer to this problem, I thought I'd share my solution with everyone.
Frankly, I'm most frustrated that this functionality isn't just given to us out of the box, but I've noticed that NetSuite has made a lot of bad design choices in their SuiteTalk API, like not making a custom class of "RecordField" for their record fields and not placing their record fields under an IEnumerable of RecordField so that programmers can loop through all values in a record in a generic way without having to EXPLICITLY name them and re-construct the same code logic over and over again... ugh...
I'm totally new to coding in general, so this is really my first attempt, so don't shoot me if I ask stupid questions ;) Right now I'm having trouble even understanding the the vast world of backend.
So I'm having some problems in my service, and even deciding which way is the best to go, scanning, querying... what?
So I -think- the way to go for me is scanning... I'm having trouble to retrieve an item from the database, based on the id of that item. Retrieving all items works like a charm, and I need something similar for getting one item. I'm getting confused when searching the web, and not really even understanding the difference for example scanfilter, scanexpression? That's why I haven't even come up with a good attempt... but what I need is scan the table and retrieve the item with the matching id. I tried looking at my method for retrieving all searchCases, and implement it for retrieving one it, as it should look quite the same, but no success...
EDITED method a bit: Method I need help with:
public SearchCase getSearchCase(String id){
//this is obviously for a list, but how do I do it for ONE item?
HashMap<String, AttributeValue> sc = new HashMap<String, AttributeValue>();
sc.put("scId", new AttributeValue().withS(id));
ScanRequest scanRequest = new ScanRequest()
.withTableName(searchCaseTableName)
.withFilterExpression("id = scId");
ScanResult scanResult = client.scan(scanRequest);
?????
return searchCase;
}
As a reference here is the method for retrieving all items, that does work:
public List<SearchCase> getSearchCases() {
final List<SearchCase> cases = new ArrayList<SearchCase>();
ScanRequest scanRequest = new ScanRequest()
.withTableName(searchCaseTableName);
ScanResult result = client.scan(scanRequest);
try {
for (Map<String, AttributeValue> item : result.getItems()) {
SearchCase searchCase = mapper.readValue(item.get("payload").getS(), SearchCase.class);
cases.add(searchCase);
}
} catch (Exception e) {
throw new RuntimeException(e);
}
return cases;
}
It has been forever, but thought I'd post the correct answer I fought with for a long time back in June. So this was the solution that worked for me for retrieving a single item:
public SearchCase getSearchCase(String id) throws Exception {
Table t = db.getTable(searchCaseTableName);
GetItemSpec gis = new GetItemSpec()
.withPrimaryKey("id", id);
Item item = t.getItem(gis);
SearchCase searchCase = mapper.readValue(StringEscapeUtils.unescapeJson(item.getJSON("payload").substring(1)), SearchCase.class);
return searchCase;
}
This method actually took a whole another approach then the way I originally thought I would solve this. So no Scanrequest, but using GetItemSpec and Item instead. This thus caused some funky backslashes in the JSON, so my frontend wouldn't accept before I ran it through StringEscapeUtils.unescapeJson, otherwise worked like a charm.
I'm having trouble to retrieve an item from the database, based on the id of that item
If you want to retrieve an item from DynamoDB based on some unique ID, then use load, which "Loads an object with the hash key given".
How do I increment a number in AWS Dynamodb?
The guide says when saving an item to simply resave it:
http://docs.aws.amazon.com/mobile/sdkforios/developerguide/dynamodb_om.html
However I am trying to use a counter where many users may be updating at the same time.
Other documentation has told me to use and UpdateItem operation but I cannot find a good example to do so.
http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.Modifying.html
However, I cannot find a method to implement the expression. In the future I will be adding values to arrays and maps. Will this be the same? My code is in Obj C
Currently my code looks like:
AWSDynamoDBUpdateItemInput *updateItemInput = [AWSDynamoDBUpdateItemInput new];
updateItemInput.tableName = #"TableName";
updateItemInput.key = #{
UniqueItemKey:#"KeyValue"
};
updateItemInput.updateExpression = #"SET counter = counter + :val";
updateItemInput.expressionAttributeValues =#{
#":val":#1
};
It looks like you're missing the last bit of code that actually makes the update item request:
AWSDynamoDB *dynamoDB = [AWSDynamoDB defaultDynamoDB];
[[dynamoDB updateItem:updateItemInput]
continueWithBlock:^id(AWSTask *task) {
if (task.error) {
NSLog(#"The request failed. Error: [%#]", task.error);
}
if (task.exception) {
NSLog(#"The request failed. Exception: [%#]", task.exception);
}
if (task.result) {
//Do something with result.
}
return nil;
}];
In DynamoDB if you want to increment the value of the any propertie/field you can use the UpdateItemRequest with action option ADD. I used in android this method would update the existing value of the field. Let me share the code snippet. You can use any actions such like add,delete,put etc.
.....
AttributeValue viewcount = new AttributeValue().withS("100");
AttributeValueUpdate attributeValueUpdate = new AttributeValueUpdate().withAction(AttributeAction.ADD).withValue(viewcount);
updateItems.put(UploadVideoData.FIELD_VIEW_COUNT, attributeValueUpdate);
UpdateItemRequest updateItemRequest = new UpdateItemRequest().withTableName(UploadVideoData.TABLE_NAME)
.withKey(primaryKey).withAttributeUpdates(updateItems);
UpdateItemResult updateItemResult = amazonDynamoDBClient.updateItem(updateItemRequest);
....
You can see the above code will add 100 count into the existing value of that field.
This code is for android but the technique would remain the same.
Thank you.
I've created a number of users in Parse. There're Facebook users and non-Facebook user. For each Facebook user I've saved an extra column of "facebookID".
Now I'd like to get all the ParseUsers that are Facebook Users. So I applied a Task to query the users with "facebookID" in them.
var Task = ParseUser.Query.WhereExists("facebookID").FindAsync().ContinueWith(t=>{
if (t.IsFaulted || t.IsCanceled) {
Debug.Log ("t.Exception=" + t.Exception);
//cannot load friendlist
return;
}
else{
fbFriends = t.Result;
foreach(var result in fbFriends){
string id = (string)result["facebookID"];
//facebookUserIDList is a List<string>
facebookUserIDList.Add(id);
}
return;
}
});
The above code works perfectly. However, I'd like to get more data from each Facebook User, for example, the current_coins that the user has. So I change the foreach loop to:
foreach(var result in fbFriends){
string id = (string)result["facebookID"];
int coins = (int)result["current_coins"];
//facebookUserIDList is a List<string>
facebookUserIDList.Add(id);
}
I've changed the facebookUserIDList into a List<Dictionary<string,object>> instead of a List<string> in order to save the other data as well. But the foreach loop does not run at all. Does it mean I can only get the facebookID from it because I specified WhereExists("facebookID") in FindAsync()? Can anybody explain it to me please?
Thank you very much in advance.
it should contain all Parse primitive data type(such as Boolean, Number, String, Date...) for each Object. but not Pointers nor Relation.
for Pointers, you can explicitly include them in the result using the "Include" method
for any ParseRelation you have to requery them
I have a deserialization webmethod which returns a list of data in webservice(asmx), and I am calling the method from client-side. However, the method is giving me an array, not a list. I understand that it is because of SOAP response which returns xml format (or something like that..)
Is it possible to return a list? If then, please tell me an idea. If not, please teach me an alternative way. (I should not use array...)
service.asmx.cs
[WebMethod]
public IList<Person> DeserializeJson(string value)
{
JavaScriptSerializer js = new JavaScriptSerializer();
IList<Person> tableData = js.Deserialize<IList<Person>>(value);
return tableData;
}
Client.aspx.cs (WebService is my service reference)
WebService.Service1SoapClient client = new WebService.Service1SoapClient();
string stream = client.CreateJsonFromDatabase();
List<WebService.Person> tableData = client.DeserializeJson(stream);
Web services do not return arrays, and they do not return lists. They return XML. The XML they return is interpreted by the client code as a list, array, or whatever.
If you consume this service by using "Add Service Reference", then you will have a choice of how to treat repeated elements in the XML. You can choose from List, Array, or several other choices.
