So I want to know how I can get all the entries where my sessionId equals to (for example: 4).
public async Task<IActionResult> Index(int? session)
{
var cardio = await _client.GetEntries<CardioModel>();
// ContentfulCollection<CardioModel> cardioModels = new ContentfulCollection<CardioModel>();
// foreach (var model in cardio)
// {
// if(model.Session == 4){
// cardioModels.add(model)
// }
// }
return View(cardio);
}
I tried this but the .add isn't a thing, I tried various ways but none of them is working and I can't find good docs about what I want. I thought probably something with .getEntriesRaw() but I don't know how to work with that.
public async Task<IActionResult> Index(int? session)
{
var cardio = await _client.GetEntries<CardioModel>();
// ContentfulCollection<CardioModel> cardioModels = new ContentfulCollection<CardioModel>();
// foreach (var model in cardio)
// {
// if(model.Session == 4){
// cardioModels.add(model)
// }
// }
return View(cardio);
}
How about just modifying just a little bit
public async Task<IActionResult> Index(int? session)
{
if (session == null || session != 4) return View(null);
var cardio = await _client.GetEntries<CardioModel>().FirstOrDefault(x => x.Session == 4);
return View(cardio);
}

I am implementing CoinPayments IPN in my application and I have trouble with passing data to the method that take their Callback. I have tried like everything I could find: TempData, SessionVariables, tried to implement it somewhere in forms and maybe Request it but that didn`t work for me. So I also tried to implement it with Global static variables. And it worked! But then came another issue: if more than one user were to buy something from website at the same time or even in between any callbacks their data will get mixed. So here I am, trying again to make Session Variables work and have no clue why they are not working as I used them before. Probably what I can think of is that because its a callback from CoinPayments and I handle something wrongly.
Here is the code I have right now: Tho I tried different variations like implementing Session in Get Payment method. Now I ended up with it and it still comes out as null in POST METHOD.
Class for handling Session Variables:
public static class MyGlobalVariables
{
public static int TokenChoice
{
get
{
if (System.Web.HttpContext.Current.Session["TokenChoice"] == null)
{
return -1;
}
else
{
return (int)System.Web.HttpContext.Current.Session["TokenChoice"];
}
}
set
{
System.Web.HttpContext.Current.Session["TokenChoice"] = value;
}
}
public static int PaymentChoice
{
get
{
if (System.Web.HttpContext.Current.Session["PaymentChoice"] == null)
{
return -1;
}
else
{
return (int)System.Web.HttpContext.Current.Session["PaymentChoice"];
}
}
set
{
System.Web.HttpContext.Current.Session["PaymentChoice"] = value;
}
}
public static string CurrentUser
{
get
{
System.Web.HttpContext.Current.Session["CurrentUser"] = System.Web.HttpContext.Current.User.Identity.Name;
return (string)System.Web.HttpContext.Current.Session["CurrentUser"];
}
}
}
Class that returns view where you click on CoinPayments button:
public ActionResult Payment(int tokenChoice, int paymentChoice)
{
ViewBag.Payment = paymentChoice;
MyGlobalVariables.PaymentChoice = paymentChoice;
MyGlobalVariables.TokenChoice = tokenChoice;
return View();
}
Callback class that handles Callback from CoinPayments:
[HttpPost]
public ActionResult Payment()
{
NameValueCollection nvc = Request.Form;
var merchant_id = id;
var ipn_secret = secret;
var order_total = MyGlobalVariables.PaymentChoice;
if (String.IsNullOrEmpty(nvc["ipn_mode"]) || nvc["ipn_mode"] != "hmac")
{
Trace.WriteLine("IPN Mode is not HMAC");
return View();
}
if (String.IsNullOrEmpty(HTTP_HMAC))
{
Trace.WriteLine("No HMAC signature sent");
return View();
}
if (String.IsNullOrEmpty(nvc["merchant"]) || nvc["merchant"] != merchant_id.Trim())
{
Trace.WriteLine("No or incorrect Merchant ID passed");
return View();
}
//var hmac = hash_hmac("sha512", request, ipn_secret.Trim());
var txn_id = nvc["txn_id"];
var item_name = nvc["item_name"];
var item_number = nvc["item_number"];
var amount1 = nvc["amount1"];
var amount2 = float.Parse(nvc["amount2"], CultureInfo.InvariantCulture.NumberFormat);
var currency1 = nvc["currency1"];
var currency2 = nvc["currency2"];
var status = Convert.ToInt32(nvc["status"]);
var status_text = nvc["status_text"];
Trace.WriteLine(status);
if (currency1 != "USD") {
Trace.WriteLine("Original currency mismatch!");
return View();
}
if (Convert.ToInt32(amount1) < Convert.ToInt32(order_total))
{
Trace.WriteLine("Amount is less than order total!");
return View();
}
if (status >= 100 || status == 2) {
using (MyDatabaseEntities1 dc = new MyDatabaseEntities1())
{
var account = dc.Users.Where(a => a.Username == MyGlobalVariables.CurrentUser).FirstOrDefault();
if (account != null && account.Paid == 0)
{
Trace.WriteLine("Payment Completed");
Trace.WriteLine("Tokens to add: " + MyGlobalVariables.TokenChoice);
account.Tokens += MyGlobalVariables.TokenChoice;
account.Paid = 1;
dc.Configuration.ValidateOnSaveEnabled = false;
dc.SaveChanges();
}
}
} else if (status < 0)
{
Trace.WriteLine(
"payment error, this is usually final but payments will sometimes be reopened if there was no exchange rate conversion or with seller consent");
} else {
using (MyDatabaseEntities1 dc = new MyDatabaseEntities1())
{
var account = dc.Users.Where(a => a.Username == MyGlobalVariables.CurrentUser).FirstOrDefault();
if (account != null)
{
account.Paid = 0;
dc.Configuration.ValidateOnSaveEnabled = false;
dc.SaveChanges();
}
}
Trace.WriteLine("Payment is pending");
}
return View();
}
As you can see there are only 3 variables I need to handle.
Also someone might ask why I use Session Variable for Current.User?
Well for some reason Callback method can not read Current.User as it return null. And well... nothing really changed as for now.
If you have ever experienced something like that or can find an issue I would be so thankful since I wasted already over 2 days on that issue.
EDIT:
After some testing I found out variables works fine if I run Post method on my own. So the problem is with handling callback from CoinPayments. Is there a specific way to deal with this?
I am trying to query orders and update them. I have been able to isolate my problem in a unit test:
[Fact(DisplayName = "OrderDocumentRepositoryFixture.Can_UpdateAsync")]
public async void Can_UpdateByQueryableAsync()
{
var order1 = JsonConvert.DeserializeObject<Order>(Order_V20170405_133926_9934934.JSON);
var orderId1 = "Test_1";
order1.Id = orderId1;
await sut.CreateAsync(order1);
foreach (var order in sut.CreateQuery())
{
order.Version = "myversion";
await sut.UpdateAsync(order);
var ordersFromDb = sut.GetByIdAsync(orderId1).Result;
Assert.Equal("myversion", ordersFromDb.Version);
}
}
where :
public IQueryable<T> CreateQuery()
{
return _client.CreateDocumentQuery<T>(UriFactory.CreateDocumentCollectionUri(_databaseId, CollectionId));
}
With this code, orders are not updated.
If I replace the CreateQuery() by what follows, it does work:
[Fact(DisplayName = "OrderDocumentRepositoryFixture.Can_UpdateAsync")]
public async void Can_UpdateByQueryableAsync()
{
var order1 = JsonConvert.DeserializeObject<Order>(Order_V20170405_133926_9934934.JSON);
var orderId1 = "Test_1";
order1.Id = orderId1;
await sut.CreateAsync(order1);
var order = sut.GetByIdAsync(orderId1).Result;
order.Version = "myversion";
await sut.UpdateAsync(order);
var ordersFromDb = sut.GetByIdAsync(orderId1).Result;
Assert.Equal("myversion", ordersFromDb.Version);
}
where
public async Task<T> GetByIdAsync(string id)
{
try
{
var documentUri = UriFactory.CreateDocumentUri(_databaseId, CollectionId, id);
var document = (T) await ((DocumentClient) _client).ReadDocumentAsync<T>(documentUri);
return document;
}
catch (DocumentClientException e)
{
if (e.StatusCode == HttpStatusCode.NotFound) return null;
throw;
}
}
I've been trying to understand why this doesn't work. Obviously i could always do a GetByIdAsync before updating, but that seems overkill?
What can't I see?
Thanks!
You create your query, but you never execute it (CreateDocumentQuery just sets up the query). Try altering your call to something like:
foreach (var order in sut.CreateQuery().ToList())
{
//
}
Also note: if you are always querying for a single document, and you know the id, then ReadDocumentAsync() (your alternate code path) will be much more effecient, RU-wise.
I am using asp.net core RoleManager to perform roleClaim(permission) based authorization. The below code work fine but it take too much time execute because i delete the roleclaim each at a time. but i want to delete roleclaims(permission) at one shot delete query , Can anyone help me ? thank's in advance.
//my controller code
public async Task<IActionResult> SaveRolePermission([FromBody] RoleClaimVM model)
{
try
{
if (string.IsNullOrEmpty(model.RoleId) || model.ClaimValues.Length <= 0) return Json(new { status = false });
var role = await _roleManager.FindByIdAsync(model.RoleId);
if (role == null) return null;
var roleClaims = _roleManager.GetClaimsAsync(role).Result.ToList();
if (roleClaims.Any())
{
foreach (var item in roleClaims)
{
await _roleManager.RemoveClaimAsync(role, item);
}
}
foreach (var item in model.ClaimValues)
{
await _roleManager.AddClaimAsync(role, new Claim(CustomClaimtypes.Permission, item.ToLower()));
}
return Json(new { status = true });
}
catch (Exception)
{
return Json(new { status = false });
}
}
Hey there I am quite new to Dart Futures and I have the following situation.
Whenever a user types a letter in the UI the addressChanged() method in my ui_component is called. This method calls the method getProposals() in my maps componenet which does an asynchronous request to the google maps API. As soon as the results are here I want to return them to the UI Component which is going to populate the propasals dropdown in the UI.
I am stuck with the last step: How (and whats the best way) to return the results of an asynchronous callback function to a parent component (while keeping an reusable maps component?).
This is what I have tried:
1) UI_Component:
// I get called if a user typed a new letter
Future addressChanged(dynamic event) async {
String id = event.target.id;
String address = event.target.value;
if(id=="pickup") {
this.pickup = address;
} else if(id=="destination") {
this.destination = address;
}
// this is where I call the subcomponent and want to get the address propasals
String proposals = await googleMap.getProposals(address,id);
print(proposals);
populateProposalDropdown();
}
2) Google Map component:
Future getProposals(String address,String id) async {
await _getProposals(address,id);
}
Future _getProposals(String address,String id) async {
if(address != "") {
autocompleteService.getPlacePredictions(
new AutocompletionRequest()
..input = address
,
(predictions,status) {
List<String> result = [];
if(status == PlacesServiceStatus.OK) {
predictions.forEach(
(AutocompletePrediction prediction) =>
result.add(prediction.description)
);
}
// HERE is the problem: How do I return this result from the callback as a result of the getProposals method?
return result;
}
);
}
}
This method doesn't return any data
Future getProposals(String address,String id) async {
await _getProposals(address,id);
}
Change it to
Future getProposals(String address,String id) {
return _getProposals(address,id);
}
This would also work, but here async and await is redunant
Future getProposals(String address,String id) async {
return await _getProposals(address,id);
}
For _getProposals you can use a Completer
Future _getProposals(String address,String id) async {
if(address != "") {
Completer completer = new Completer();
autocompleteService.getPlacePredictions(
new AutocompletionRequest()
..input = address
,
(predictions,status) {
List<String> result = [];
if(status == PlacesServiceStatus.OK) {
predictions.forEach(
(AutocompletePrediction prediction) =>
result.add(prediction.description)
);
}
// HERE is the problem: How do I return this result from the callback as a result of the getProposals method?
completer.complete(result);
}
);
return completer.future;
}
return null;
}
I'm developing a Win 8 app which needs to do some possibly long running looping and calculations based around the data input by the user. This calculation is run often to update the results in real time.
The calculations are done by a calculator class. I will use example code to give an idea
public class ResultCalculator
{
List<Data> Input1 = new List<Data>();
IQueryable<int> Input2;
IQueryable<Data2> Input3;
public ResultCalculator(List<int> items1, List<Data2> items2)
{
items1.Sort((x,y) => y.CompareTo(x));
Input2 = items1.AsQueryable();
Input3 = items2.AsQueryable().OrderByDescending(w => w.LValue);
}
public void CalculateLValues()
{
foreach (var v in Input3)
{
for (int i = 1; i <= v.Quantity; i++)
{
if (Input1.Count > 0)
{
Data existing = FindExisting(v.LValue, 4);
if (existing != null)
{
existing.Add(v.LValue);
}
else
{
FindNew(v.LValue);
}
}
else
{
FindNew(v.LValue);
}
}
}
OptimisePass1();
}
public void FindNew(int LValue)
{
int options = FindNewItem(LValue, 0);
if (options != 0)
{
Data newdata = new Data(options);
newdata.Add(LValue);
Input1.Add(newdata);
}
}
public void OptimisePass1()
{
foreach (var w in Input1)
{
var ShorterLValues = from sl in Input2 where sl < w.LValue orderby sl select sl;
foreach (var sl in ShorterLValues)
{
if (sl > w.LValue - w.Remaining)
{
w.LValue = sl;
w.CalculateRemaining();
}
}
// MORE CALCULATION TO DO IN ANOTHER LOOP
}
}
public Data FindExisting(int LValueRequired, int additionalvalue)
{
Input1.OrderBy(w => w.LValue);
foreach (var sl in Input1.Where(i => i.Remaining > 0).OrderBy(i => i.Remaining))
{
if (sl.Remaining >= LValueRequired + additionalvalue)
{
return sl;
}
}
return null;
}
public int FindNewItem(int LValueRequired)
{
foreach (var sl in Input2)
{
if (sl >= LValueRequired + 4)
{
return sl;
}
}
return 0;
}
}
This class is the used from my ViewModel as below...
public async Task UpdateCalculationAsync()
{
var data1 = new List<int>(sInput);
var reqlist = new List<Data2>(sInput2);
var lc = new ResultCalculator(data1, data2);
NL.Clear();
await Task.Run(() => lc.CalculateLValues());
foreach (var i in lc.Data1)
{
NL.Add(i);
}
}
Without any async use this held up the UI when it ran if there were many items in the lists. So I added the "await Task.Run(() => lc.CalculateLValues())" to make it run async. I've got a basic grasp of async but not really understood how to properly make my classes run in async. Is this approach correct?
I believe that what I've done hands off the calculation to the background thread. Certainly the UI now remains responsive and can be used whilst the calculation is running. Once the result is calculated my viewmodel gets the result and the UI updates. What I'd really rather have is for my ResultCalculator class to have Task returning methods which I can await. However I'm really struggling on how to refactor for that. I'm not even sure there's a need if this works and is a valid approach. But I'm not 100% convinced it is the proper use of the async pattern and wanted to check if it can be improved?
suggest to do something like this:
// user will do some action on the UI to trigger the compute
public async Task Button1_Click(..)
{
await this.ViewModel.RecalculateAsync();
}
class ViewModel
{
public async Task RecalculateAsync()
{
var data1 = new List<int>(sInput);
var reqlist = new List<Data2>(sInput2);
var lc = new ResultCalculator(data1, data2);
await Task.Run(() => lc.CalculateLValues());
// I am not sure that is NL - if it is items like property on viewmodel that is bound to ListView like control in xaml - that should be fine.
// otherwise, add code here to add the list of result items to an observable collection
// expose this collection as Items property on viewmodel and bind in xaml to ListView.ItemsSource
}
}
