So I'm querying my database and for a return I have two different possibilties, one for if the model set is empty and one for if it has information. However when I run it with an empty table, I still get the response that thinks it has data.
Query works and all, but I just get the same response everytime either success with calls = [] or success with calls having data.
IEnumerable<Details> detail = db.Details Where(blah blah blah).ToList().Select(a => new Details { blah blah blah });
var ResponseTrue = new DetailResponse() { status = true, statusMessage = "Success", calls = detail };
var ResponseFalse = new DetailResponse() { status = false, statusMessage = "Set is Empty", calls = detail };
if (detail != null)
{
return Ok(ResponseTrue);
}
return Ok(ResponseFalse);
Try with Any()
if (!detail.Any())
{
//your code goes here
}

Hello I'm trying to take data from a sql table but the data that I want to check is into an array, so I need compare the data to check if an user is into the group, the array only have the IDs from users and the specific ID that I want is being bringing to me through the login.
This code is in Typescript.
If you need more information let me know please.
class CompanyController {
async consultCompanys(req: Request, res: Response) {
let response: ResponseModel = new ResponseModel(ECodeResponse.Ok, "", []);
const { UserId } = req.body;
try {
const Companies: any = await pool.query(
`SELECT (CompanyId) From Companies Where Members = '${UserId}'`
);
response.Code = ECodeResponse.Ok;
response.Message = EWarningMessage.Error;
return res.json(response);
} catch (error) {
response.Code = ECodeResponse.Warning;
response.Message = EWarningMessage.Error;
return res.json(response);
}
}
}
I'm a litle oxidated in this kind of consults
I'm capturing model validation errors using the code below and outputting a custom 400 response from the CustomProblemDetails object which works great. My question is, I want to log from within the CustomProblemDetails object but don't see how I can use DI. I've passed in context which gives me access to the services but is this the way to go? If so it appears I can only get access to the ILoggerFactory how do I log using ILoggerFactory?
services.AddMvc()
.SetCompatibilityVersion(CompatibilityVersion.Version_2_2)
.ConfigureApiBehaviorOptions(options =>
{
options.InvalidModelStateResponseFactory = context =>
{
var problemDetails = new CustomProblemDetails(context)
{
Type = "https://contoso.com/probs/modelvalidation",
Title = "One or more model validation errors occurred.",
Status = StatusCodes.Status400BadRequest,
Detail = "See the errors property for details.",
Instance = context.HttpContext.Request.Path
};
return new BadRequestObjectResult(problemDetails)
{
ContentTypes = { "application/problem+json" }
};
};
});
For logging in InvalidModelStateResponseFactory, you could try code like:
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2).ConfigureApiBehaviorOptions(options =>
{
options.InvalidModelStateResponseFactory = context =>
{
var loggerFactory = context.HttpContext.RequestServices.GetRequiredService<ILoggerFactory>();
var logger = loggerFactory.CreateLogger("Logger From Invalid Model");
var problemDetails = new CustomProblemDetails(context)
{
Type = "https://contoso.com/probs/modelvalidation",
Title = "One or more model validation errors occurred.",
Status = StatusCodes.Status400BadRequest,
Detail = "See the errors property for details.",
Instance = context.HttpContext.Request.Path
};
logger.LogError(JsonConvert.SerializeObject(problemDetails));
return new BadRequestObjectResult(problemDetails)
{
ContentTypes = { "application/problem+json" }
};
};
});
I have a JS Array of Objects which, at time of Post contains three variables per object:
ParticipantId,
Answer,
ScenarioId
During post, there is an Array the size of 8 (at current anyway) which all correctly contain data. When I call post request, the Controller does get hit as the breakpoint triggers, the issue is when I view the List<SurveyResponse> participantScenarios it is shown as having 0 values.
The thing I always struggle to understand is that magic communication and transform between JS and .Net so I am struggling to see where it is going wrong.
My JS Call:
postResponse: function () {
var data = JSON.stringify({ participantScenarios: this.scenarioResponses})
// POST /someUrl
this.$http.post('ScenariosVue/PostScenarioChoices', data).then(response => {
// success callback
}, response => {
// error callback
});
}
My .Net Core Controller
[HttpPost("PostScenarioChoices")]
public async Task<ActionResult> PostScenarioChoices(List<SurveyResponse> participantScenarios)
{
List<ParticipantScenarios> addParticipantScenarios = new List<ParticipantScenarios>();
foreach(var result in participantScenarios)
{
bool temp = false;
if(result.Answer == 1)
{
temp = true;
}
else if (result.Answer == 0)
{
temp = false;
}
else
{
return StatusCode(400);
}
addParticipantScenarios.Add(new ParticipantScenarios
{
ParticipantId = result.ParticipantId,
Answer = temp,
ScenarioId = result.ScenarioId
});
}
try
{
await _context.ParticipantScenarios.AddRangeAsync(addParticipantScenarios);
await _context.SaveChangesAsync();
return StatusCode(201);
}
catch
{
return StatusCode(400);
}
}
I'm trying to store few user data into a roamingFolder method/property of Windows Storage in an app using JavaScript. I'm following a sample code from the Dev Center, but no success. My code snippet is as follows : (OR SkyDrive link for the full project : https://skydrive.live.com/redir?resid=F4CAEFCD620982EB!105&authkey=!AE-ziM-BLJuYj7A )
filesReadCounter: function() {
roamingFolder.getFileAsync(filename)
.then(function (filename) {
return Windows.Storage.FileIO.readTextAsync(filename);
}).done(function (data) {
var dataToRead = JSON.parse(data);
var dataNumber = dataToRead.count;
var message = "Your Saved Conversions";
//for (var i = 0; i < dataNumber; i++) {
message += dataToRead.result;
document.getElementById("savedOutput1").innerText = message;
//}
//counter = parseInt(text);
//document.getElementById("savedOutput2").innerText = dataToRead.counter;
}, function () {
// getFileAsync or readTextAsync failed.
//document.getElementById("savedOutput2").innerText = "Counter: <not found>";
});
},
filesDisplayOutput: function () {
this.filesReadCounter();
}
I'm calling filesDisplayOutput function inside ready method of navigator template's item.js file, to retrieve last session's data. But it always shows blank. I want to save upto 5 data a user may need to save.
I had some trouble running your code as is, but that's tangential to the question. Bottom line, you're not actually reading the file. Note this code, there's no then or done to execute when the promise is fulfilled.
return Windows.Storage.FileIO.readTextAsync(filename);
I hacked this in your example solution and it's working... typical caveats of this is not production code :)
filesReadCounter: function () {
roamingFolder.getFileAsync(filename).then(
function (filename) {
Windows.Storage.FileIO.readTextAsync(filename).done(
function (data) {
var dataToRead = JSON.parse(data);
var dataNumber = dataToRead.count;
var message = "Your Saved Conversions";
//for (var i = 0; i < dataNumber; i++) {
message += dataToRead.result;
document.getElementById("savedOutput1").innerText = message;
//}
//counter = parseInt(text);
//document.getElementById("savedOutput2").innerText = dataToRead.counter;
}, function () {
// readTextAsync failed.
//document.getElementById("savedOutput2").innerText = "Counter: <not found>";
});
},
function () {
// getFileAsync failed
})
},
I have a fairly simple controller that gets a simple json list of objects ...
function ProductGroupsCtrl($scope, $http, $routeParams, sharedService, popupService) {
$scope.list = null;
$scope.selectedItem = null;
$scope.selectedItemJsonString = '';
$scope.selectItem = function (item) {
$scope.selectedItem = item;
$scope.selectedItemJsonString = JSON.stringify(item);
//alert(JSON.stringify(item));
};
$scope.closePopup = function () {
$scope.selectedItem = null;
$scope.selectedItemJsonString = '';
};
// sharedService.prepForBroadcast($routeParams.anotherVar);
$http({
method: 'GET',
url: '/ProductGroup'
}).success(function (data) {
$scope.list = data;
}).
error(function (data) {
$scope.message = 'There was an error with the data request.';
});
}
I then try to mock the request in the test class:
var scope, ctrl, $httpBackend, sharedServiceMock = {}, popupServiceMock = {};
beforeEach(inject(function (_$httpBackend_, $rootScope, $controller) {
$httpBackend = _$httpBackend_;
$httsypBackend.expectGET('/ProductGroup').
respond([{
ProductGroupID: 5,
MenuTitle: "Promotional Products",
AlternativeText: "Coming soon - a collection of environmentally friendly Promotional Products",
OrdinalPosition: 5,
Active: false
}]);
scope = $rootScope.$new();
ctrl = $controller(ProductGroupsCtrl, {
$scope: scope,
$http: $httpBackend,
sharedService: sharedServiceMock,
popupService: popupServiceMock
});}));
However I receive an error in the testacular window object undefined. What have I done wrong here?
Found the answer. If I remove the error callback function from the $http.get method then it works, i.e. remove the following ...
error(function (data) {
$scope.message = 'There was an error with the data request.';
}
I have to say Angular sure is a steep learning curve for someone who is not a day to day JavaScript programmer (although I seem to be doing more and more). Thanks for the help anyway KatieK :-)
