I have below LUIS Dialog class from which I redirect it to formbuilder class, I want to pass a context.Activity to my formbuilder method which and it resides in another class is given right after the code.How to do this?
public class LUISManager : LuisDialog<object>
{
[LuisIntent("BookFlight")]
public async Task BookFlight(IDialogContext context, LuisResult result)
{
//context.Activity
FlightBooking cb = new FlightBooking();
BuildFormDelegate<FlightBooking> MakeFlightBookingForm = FlightBooking.BuildForm;
var flightBooking = new FormDialog<FlightBooking>(cb, MakeFlightBookingForm, FormOptions.PromptInStart, null);
context.Call<FlightBooking>(flightBooking, FlightBookingComplete);
}
}
[Serializable]
public class FlightBooking
{
public static IForm<FlightBooking> BuildForm()
{
return new FormBuilder<FlightBooking>().Message("Tell me meeting details!")
.Field(nameof(title))
.Field(nameof(StartDate))//, validate: ValidateStartDate
.Field(nameof(EntryTime), validate:ValidateCallTime)
.Build();
}
},
I know we can pass "IDialogContext context" parameter in BuildForm method but how to pass it from BuildFormDelegate
Change the constructor to:
public static IForm<FlightBooking> BuildForm(IDialogContext context)
{}
Then you can use a lambda expression:
BuildFormDelegate<FlightBooking> MakeFlightBookingForm = ()=>FlightBooking.BuildForm(context);

iam trying to map just a long field coming from my url route to create a Query Object from my controller, can i use auto mapper
CreateMap(MemberList.None);
Source :-long id
Destination:-
public class GetPlanQuery : IRequest<PlanDto>
{
public long Id { get; }
public GetPlanQuery(long id)
{
Id = id;
}
internal sealed class GetPlanQueryHandler : IRequestHandler<GetPlanQuery, PlanDto>
{
//Logic will go here
}
}
Map i am using is as below
CreateMap<long, GetPlanQuery>(MemberList.None);
i am getting an exception while executing as
System.ArgumentException:
needs to have a constructor with 0 args or only optional args.'
As Lucian correctly suggested you can achieve this kind of custom mapping by implementing ITypeConverter:
public class LongToGetPlanQueryTypeConverter : ITypeConverter<long, GetPlanQuery>
{
public GetPlanQuery Convert(long source, GetPlanQuery destination, ResolutionContext context)
{
return new GetPlanQuery(source);
}
}
then specify it's usage in AutoMapper configuration:
configuration.CreateMap<long, GetPlanQuery>()
.ConvertUsing<LongToGetPlanQueryTypeConverter>();
EDIT
Alternatively, you can just use a Func:
configuration.CreateMap<long, GetPlanQuery>()
.ConvertUsing(id => new GetPlanQuery(id));
I get tutorial from here : https://laravel-excel.maatwebsite.nl/docs/3.0/export/basics
<?php
...
use App\Exports\ItemsDetailsExport;
class ItemController extends Controller
{
...
public function exportToExcel(ItemsDetailsExport $exporter, $id)
{
//dd($id); I get the result
return $exporter->download('Summary Detail.xlsx');
}
}
My export like this :
<?php
namespace App\Exports;
use App\Repositories\Backend\ItemDetailRepository;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\Exportable;
use Illuminate\Support\Facades\Input;
class ItemsDetailsExport implements FromCollection
{
use Exportable;
protected $itemDetailRepository;
public function __construct(ItemDetailRepository $itemDetailRepository)
{
$this->itemDetailRepository = $itemDetailRepository;
}
public function collection()
{
$test = Input::get('id');
dd('yeah', $test);
}
}
I want to pass id parameter to export file. I try like that, but I don't get the id. The id is null
How can I solve this problem?
For passing data from controller to laravel excel function we can pass and use data like below
For example, we have to pass data year like 2019 we will pass like below
in controller
Excel::download(new UsersExport(2019), 'users.xlsx');
In laravel import file
class UsersExport implements FromCollection {
private $year;
public function __construct(int $year)
{
$this->year = $year;
}
public function collection()
{
return Users::whereYear('created_at', $this->year)->get();
}
}
you can refer all following official documentation link
https://docs.laravel-excel.com/3.1/architecture/objects.html#plain-old-php-object
Unfortunately you can't use normal dependency injection when you have a specific parameter. This is what you can do though:
class ItemsDetailsExport implements FromCollection
{
use Exportable;
protected $itemDetailRepository;
protected $id;
public function __construct(ItemDetailRepository $itemDetailRepository, $id)
{
$this->itemDetailRepository = $itemDetailRepository;
$this->id = $id;
}
public function collection()
{
$test = $this->id;
dd('yeah', $test);
}
}
Now the problem is that the container doesn't know how to resolve $id however there are two ways around this.
Manual passing of $id:
public function exportToExcel($id)
{
$exporter = app()->makeWith(ItemsDetailsExport::class, compact('id'));
return $exporter->download('Summary Detail.xlsx');
}
Route injection:
Define your route as:
Route::get('/path/to/export/{itemExport}', 'ItemController#exportToExcel');
In your RouteServiceProvider.php:
public function boot() {
parent::boot();
//Bindings
Route::bind('itemExport', function ($id) { //itemExport must match the {itemExport} name in the route definition
return app()->makeWith(ItemsDetailsExport::class, compact('id'));
});
}
Then your route method is simplified as:
public function exportToExcel(ItemsDetailsExport $itemExport)
{
//It will be injected based on the parameter you pass to the route
return $itemExport->download('Summary Detail.xlsx');
}
I am using Unity as IOC and trying to inject an interface with a factory method which takes a interface as a parameter.
For some reason the configReader parameter in the factory method GetTitleParser(), is null and not getting the injected ConfigurationReader() instance.
When i place a debug point at the line in RegisterTypes method where the new InjectionFactory exists, ITitleParser is not showing as mapped to a proper mapped type.
can anyone help what am i doing wrong here?
Here is my code:
public class UnityContainerBuilder
{
public static IUnityContainer Build()
{
var container = new UnityContainer();
RegisterTypes(container);
return container;
}
public static void RegisterTypes(IUnityContainer container)
{
// NOTE: To load from web.config uncomment the line below. Make sure to add a Microsoft.Practices.Unity.Configuration to the using statements.
container.LoadConfiguration();
container.RegisterType<IConfigurationReader, ConfigurationReader>();
container.RegisterType<ITitleParser>(new InjectionFactory(c => ParserFactory.GetTitleParser()));
}
}
public class ParserFactory
{
public static ITitleParser GetTitleParser(IConfigurationReader configReader=null)
{
if(configReader==null) configReader = new ConfigurationReader();
/* rest of code here...*/
return parser;
}
}
It works when i use the following code. Is this the right way to do this?
container.RegisterType<IConfigurationReader, ConfigurationReader>();
container.RegisterType<ITitleParser>(new InjectionFactory(c =>
{
var configReader = c.Resolve<IConfigurationReader>();
var parser = ParserFactory.GetTitleParser(configReader);
return parser;
}));
When you use default parameters it's equal to:
container.RegisterType<ITitleParser>(
new InjectionFactory(c => ParserFactory.GetTitleParser(null)));
Because, compiler inserts all default values in method calls (null in your case).
So, your code is valid:
container.RegisterType<ITitleParser>(new InjectionFactory(c =>
{
var configReader = c.Resolve<IConfigurationReader>();
var parser = ParserFactory.GetTitleParser(configReader);
return parser;
}));
But i advice you to remove default value to make code more expressive.
Your code is valid but maybe you can avoid messing up with InjectionFactory parameters and ParserFactory.
public class UnityContainerBuilder
{
public static IUnityContainer Build()
{
var container = new UnityContainer();
RegisterTypes(container);
return container;
}
public static void RegisterTypes(IUnityContainer container)
{
// NOTE: To load from web.config uncomment the line below. Make sure to add a Microsoft.Practices.Unity.Configuration to the using statements.
container.LoadConfiguration();
container.RegisterType<IConfigurationReader, ConfigurationReader>();
container.RegisterInstance<IAppConfig>(container.Resolve<IConfigurationReader>().ReadConfiguration());
container.RegisterType<ITitleParser, TitleParser>();
}
}
public class AppConfig: IAppConfig
{
public AppConfig(){}
//value1 property
//value2 property
//etc
}
public class ConfigurationReader: IConfigurationReader
{
public ConfigurationReader(){}
public IAppConfig ReadConfiguration(){
var currentConfig = new AppConfig();
//read config from file, DB, etc and init currentCongif
return currentConfig;
}
}
public class TitleParser : ITitleParser
{
public TitleParser(IAppConfif)
{
//config already readed, just do the work
}
}
I have a Person and a PersonViewModel. I created a map from Person => PersonViewModel. The problem is that PersonViewModel's only constructor needs an argument (it has a dependency that I want to be injected) and AutoMapper is complaining because it says it needs a parameterless constructor.
To fix it, I used the ConstructServicesUsing method, but I haven't been successful with it :(
To illustrate the case, I created a test for you to see what I'm doing. It's pretty simple:
[TestMethod]
public void TestConstructServicesUsing()
{
Mapper.Initialize(configuration =>
{
configuration.ConstructServicesUsing(FactoryMethod);
configuration.CreateMap<Person, PersonViewModel>();
});
Mapper.AssertConfigurationIsValid();
var person = new Person();
var personViewModel = Mapper.Map<Person, PersonViewModel>(person);
}
private object FactoryMethod(Type type)
{
throw new NotImplementedException();
}
}
The rest of the code is the classes and interface definitions. They are almost empty.
public class SomeyDependency : ISomeDependency
{
}
public class PersonViewModel
{
private readonly ISomeDependency service;
public PersonViewModel(ISomeDependency service)
{
this.service = service;
}
public string Name { get; set; }
}
public class Person
{
public string Name { get; set; }
}
public interface ISomeDependency
{
}
As you see, I provide AutoMapper with a FactoryMethod, but it never get called.
When it reaches the last line of the test (Mapper.Map<...>()) it throws an excepton saying:
AutoMapper.AutoMapperMappingException:
Mapping types:
Person -> PersonViewModel
MappingWithContainerTests.Person -> MappingWithContainerTests.PersonViewModel
Destination path:
PersonViewModel
Source value:
MappingWithContainerTests.Person ---> System.ArgumentException: Type needs to have a constructor with 0 args or only optional args
Parameter name: type
What's the problem?
Why isn't the FactoryMethod being called?
As #khorvat mention where is missing .ConstructUsingServiceLocator(), for concrete mapping.
Also you can set constructor directly by
.ConstructUsing(source => Method(source.anySourceOptions))
Or as exception said:
PersonViewModel, must have a constructor with 0 args or only optional
args. You have only one constructor with 1 not optional argument
you may create one more constructor without args:
public PersonViewModel()
{
this.service = new SomeDependency();
}
I'm using .NET Core 3.1 and Automapper.Extensions.Microsoft.DependencyInjection.
This does not work for me (Same error as yours):
public class AutoMapping : Profile
{
public AutoMapping()
{
CreateMap<Context, MainViewModel>()
.ReverseMap()
.ConstructUsingServiceLocator();
}
}
But this does work:
public class AutoMapping : Profile
{
public AutoMapping()
{
CreateMap<Context, MainViewModel>()
.ConstructUsingServiceLocator()
.ReverseMap();
}
}
I still do not fully understand the cause.
This is my test
[TestClass]
public class RepositoryTests
{
private APurchaseOrderRepository _repository;
[TestInitialize]
public void TestInitialize()
{
_repository = new FakePurchaseOrderRepository();
}
[TestMethod]
public void RepositoryGetPurchaseOrdersForStoreCallsValidatePurchaseOrders()
{
var store = new Store();
var mockRepo = new Mock<APurchaseOrderRepository>();
mockRepo.Protected().Setup("ValidatePurchaseOrders", ItExpr.IsAny<List<PurchaseOrder>>());
_repository.GetPurchaseOrders(store);
mockRepo.Protected().Verify("ValidatePurchaseOrders", Times.Once(), ItExpr.IsAny<List<PurchaseOrder>>());
}
}
APurchaseOrderRepository and it's interface look like this
public interface IPurchaseOrderRepository
{
List<PurchaseOrder> GetPurchaseOrders(Store store);
}
public abstract class APurchaseOrderRepository : IPurchaseOrderRepository
{
public abstract List<PurchaseOrder> GetPurchaseOrders(Store store);
protected virtual bool ValidatePurchaseOrders(List<PurchaseOrder> purchaseOrders)
{
return true;
}
}
And my Fake
public class FakePurchaseOrderRepository : APurchaseOrderRepository
{
public override List<PurchaseOrder> GetPurchaseOrders(Store store)
{
var purchaseOrders = new List<PurchaseOrder>();
ValidatePurchaseOrders(purchaseOrders);
return purchaseOrders;
}
}
However, my test fails with:
Test method
PreSwapTests.RepositoryTests.RepositoryGetPurchaseOrdersForStoreCallsValidatePurchaseOrders
threw exception: Moq.MockException: Expected invocation on the mock
once, but was 0 times: mock =>
mock.ValidatePurchaseOrders(It.IsAny())
Configured setups: mock =>
mock.ValidatePurchaseOrders(It.IsAny()), Times.Never No
invocations performed.
What am I doing wrong?
Notes:
Moq.4.0.10827
Update:
I think it is this line mockRepo.Protected().Setup("ValidatePurchaseOrders");, because I need to add the parameters to it as a second argument, but I can't seem to get it correct.
Update 2:
Made some modifications, now it compiles, but isn't counting correctly...or something, error message and code are both updated above.
Realized I was doing this all wrong, changed my objects to work with this test
[TestMethod]
public void RepositoryGetPurchaseOrdersForStoreCallsValidatePurchaseOrders()
{
var store = new Store();
var mockPurchaseOrderProvider = new Mock<IPurchaseOrderProvider>();
var mockPurchaseOrderValidator = new Mock<IPurchaseOrderValidator>();
var purchaseOrderRepository = new PurchaseOrderRepository(mockPurchaseOrderProvider.Object, mockPurchaseOrderValidator.Object);
mockPurchaseOrderValidator.Setup(x => x.ValidatePurchaseOrders(It.IsAny<List<PurchaseOrder>>()));
purchaseOrderRepository.GetPurchaseOrders(store);
mockPurchaseOrderValidator.Verify(x => x.ValidatePurchaseOrders(It.IsAny<List<PurchaseOrder>>()), Times.Once());
}
This is a much better structure now I think.
It's because ValidatePurchaseOrders is not in your IPurchaseOrderRepository interface.
The repository is declared as private IPurchaseOrderRepository _repository; so it can only see what is in the interface.
