enter image description hereI want to implement versioning in azure mobile service so I am not able to find the endpoints to configure and based on version number it will take the code.
Now URL is
http://{{host}}/tables/EntityName
but my requirement is
http://{{host}}/tables/v1/EntityName
or
http://{{host}}/tables/v2/EntityName
So please help me on this.
According to your requirement, I followed Microsoft/aspnet-api-versioning to check the versioning with azure mobile app project. You could refer to the details below to achieve your purpose.
Install the Microsoft.AspNet.WebApi.Versioning package.
Enable the API versioning in your Startup.MobileApp.cs as follows:
public static void ConfigureMobileApp(IAppBuilder app)
{
HttpConfiguration config = new HttpConfiguration();
var constraintResolver = new DefaultInlineConstraintResolver()
{
ConstraintMap =
{
["apiVersion"] = typeof( ApiVersionRouteConstraint )
}
};
config.AddApiVersioning();
config.MapHttpAttributeRoutes(constraintResolver);
//your mobile configuration
app.UseWebApi(config);
}
For your TableController, you could define it as follows:
tables/v1.0/todoitem
[ApiVersion("1.0")]
[RoutePrefix("tables/v{version:apiVersion}/todoitem")]
public class TodoItemController : TableController<ToDoItem>
{
private MobileServiceContext context;
protected override void Initialize(HttpControllerContext controllerContext)
{
base.Initialize(controllerContext);
context = new MobileServiceContext();
DomainManager = new EntityDomainManager<ToDoItem>(context, Request);
}
[Route]
// GET tables/v{version}/todoitem
public IQueryable<ToDoItem> GetAllTodoItems()
{
return Query();
}
}
tables/v2.0/todoitem
[ApiVersion("2.0")]
[ControllerName("TodoItem")]
[RoutePrefix("tables/v{version:apiVersion}/todoitem")]
public class TodoItemV2Controller : TableController<ToDoItem>
{
private MobileServiceContext context;
protected override void Initialize(HttpControllerContext controllerContext)
{
base.Initialize(controllerContext);
context = new MobileServiceContext();
DomainManager = new EntityDomainManager<ToDoItem>(context, Request);
}
[Route]
// GET tables/v{version}/todoitem
public IQueryable<ToDoItem> GetAllTodoItems()
{
return Query();
}
}
For more details, you could refer to ASP.NET API Versioning.

Implementing ExceptionFilterAttribute OnException method and need to redirect
The old implementation (.Net 48) was
exceptionContext.Controller.TempData.Remove("");
exceptionContext.Controller.TempData.Add("");//exception message is added
exceptionContext.Controller.ControllerContext.HttpContext.Response.Redirect(url);
For the redirect I guess I can:
exceptionContext.HttpContext.Response.Redirect(url);//Is this correct?
Please suggest alternate for the remove and add?
In .net 6,there's no exceptionContext.Controller.TempData if you want to access TempData in your ExceptionFilter,you could try to inject the TempdataDictionaryFactory into the filter
For example, I tried as below:
public class MyExceptionFilter : ExceptionFilterAttribute
{
private readonly ITempDataDictionaryFactory _tempDataDictionaryFactory;
public MyExceptionFilter(ITempDataDictionaryFactory tempDataDictionaryFactory)
{
_tempDataDictionaryFactory = tempDataDictionaryFactory;
}
public override void OnException(ExceptionContext context)
{
var tempData = _tempDataDictionaryFactory.GetTempData(context.HttpContext);
tempData.Add("key", "value");
context.Result = new RedirectToActionResult("Error", "Home", null);
}
}
in Program.cs:
builder.Services.AddControllersWithViews(x=>x.Filters.Add(typeof(MyExceptionFilter)));
The Result:
I've a route like Admin/Vendor in my MVC application . Without changing this route I need to point this same route to another method say CustomAdmin/CustomVendor.
I tried attribute routing but no luck . Is there any way to do this. My current code is given below
Original Method:
public class AdminController
{
public ActionResult Vendor()
{
return View();
}
}
Custom Method:
public class CustomAdminController
{
[Route("Admin/Vendor")]
public ActionResult CustomVendor()
{
return View();
}
}
As you're developing a plugin. You have to add your custom route to the RouteProvider.
In default nopCommerce AdminController and Vendor doesn't exists, so I assume that you're trying to override vendor list method of admin.
Which looks like:
public partial class RouteProvider : IRouteProvider
{
public void RegisterRoutes(RouteCollection routes)
{
var route = routes.MapRoute("Plugin.GroupName.PluginName.CustomVendor",
"Admin/Vendor/List",
new { controller = "CustomAdminController", action = "CustomVendor", orderIds = UrlParameter.Optional, area = "Admin" },
new[] { "Nop.Plugin.GroupName.PluginName.Controllers" });
route.DataTokens.Add("area", "admin");
routes.Remove(route);
routes.Insert(0, route);
}
public int Priority
{
get
{
return 100; // route priority
}
}
}
Side Note: GroupName and PluginName should be your plugin group name and plugin name.
Hope this helps !
On your plugin which class implements the interface IRouteProvider, you can easily override the route there.
Likewise I have a class named RouteProvider in my plugin, So I have Implemented the abstract function RegisterRoutes and simply it can be overrided by
routes.MapRoute("Plugin.Promotion.Combo.SaveGeneralSettings",
"Admin/Vendor",
new { controller = "CustomAdmin", action = "CustomVendor", },
new[] { "Nop.Plugin.Promotion.Combo.Controllers" }
);
Here Plugin.Promotion.Combo must be replaced by your plugin directory.And using SaveGeneralSettings or any things you want to use that will be your route url
I have a custom Nancy Bootstrapper which uses StructureMapNancyBootstrapper but the issue is the same regardless of container.
public class CustomNancyBootstrapper : StructureMapNancyBootstrapper
{
protected override void RequestStartup(IContainer container, IPipelines pipelines, NancyContext context)
{
var auth = container.GetInstance<ICustomAuth>();
auth.Authenticate(context);
}
}
I want to write a test to assert that Authenticate is called with the context... something like this...
[Test]
public void RequestStartup_Calls_CustomAuth_Authenticate_WithContext()
{
// set up
var mockAuthentication = new Mock<ICustomAuth>();
var mockContainer = new Mock<IContainer>();
var mockPipelines = new Mock<IPipelines>();
var context = new NancyContext();
mockContainer.Setup(x => x.GetInstance<ICustomAuth>()).Returns(mockAuthentication.Object);
// exercise
_bootstrapper.RequestStartup(_mockContainer.Object, _mockPipelines.Object, context);
// verify
mockAuthentication.Verify(x => x.Authenticate(context), Times.Once);
}
The problem is that I can't call RequestStartup because it's protected as defined in NancyBootstrapperBase.
protected virtual void RequestStartup(TContainer container, IPipelines pipelines, NancyContext context);
Is there a "proper"/"offical" Nancy way to do this without creating another derived class and exposing the methods as that just seems like a hack?
Thanks
I guess you can "fake" the request by using Browser from Nancy.Testing:
var browser = new Browser(new CustomNancyBootstrapper());
var response = browser.Get("/whatever");
There is a good set of articles about testing NancyFx application:
http://www.marcusoft.net/2013/01/NancyTesting1.html
Turns out Nancy offers a IRequetStartup interface so you can take the code out of the custom bootstrapper and do something like this...
public class MyRequestStart : IRequestStartup
{
private readonly ICustomAuth _customAuthentication;
public MyRequestStart(ICustomAuth customAuthentication)
{
if (customAuthentication == null)
{
throw new ArgumentNullException(nameof(customAuthentication));
}
_customAuthentication = customAuthentication;
}
public void Initialize(IPipelines pipelines, NancyContext context)
{
_customAuthentication.Authenticate(context);
}
}
and the test is easy and concise
[Test]
public void When_Initialize_Calls_CustomAuth_Authenticate_WithContext()
{
// set up
var mockAuth = new Mock<ICustomAuth>();
var requestStartup = new MyRequestStart(mockAuth.Object);
var mockPipeline = new Mock<IPipelines>();
var context = new NancyContext();
// exercise
requestStartup.Initialize(mockPipeline.Object, context);
// verify
mockAuth.Verify(x => x.Authenticate(context), Times.Once);
}

I'd like to know how I can have Imports in my custom ExportProvider. Here's an example of what I'm trying to do:
public class MyExportProvider : ExportProvider
{
private List<Export> _exports;
[Import()]
private IConfig _config;
public MyExportProvider()
base()
{
_exports = new List<Export>();
}
protected override IEnumerable<Export> GetExportsCore(ImportDefinition definition,
AtomicComposition composition)
{
if (!_exports.Any())
Initialize();
return _exports.Where(x => definition.IsConstraintSatisfiedBy(s.Definition);
}
private void Initialize()
{
var contractName = typeof(MyObject).FullName;
var exportDefinition = new ExportDefinition(contractName, null);
var export = new Export(exportDefinition, () => new MyObject(_config));
_exports.Add(export);
}
}
I am adding the provider when I create the CompositionContainer.
Unfortunately, the import is never satisfied. I can see this by setting AllowDefaults = true so my provider is created, but _config is always null.
How can I configure the container and/or provider so the Import will be satisfied?
When you are adding your export provider you are still creating your composition container. Thus I don't see how you can use the not yet created composition container to import parts of your custom export provider.
What I would do is first create a temporary CompositionContainer that will be used to create MyExportProvider.
Afterwards use the MyExportProvider to create your second final CompositionContainer that will be used by the rest of the application.
EDIT:
// this is your real container, only shown here for reference
CompositionContainer container;
public void BootstrapContainerMethod()
{
// Replace this part with the catalogs required to create your export provider.
var catalog = new AggregateCatalog();
catalog.Catalogs.Add(new DirectoryCatalog("./bin", "*.dll"));
// Your temporary container, declared here in local scope
// will be disposed because of using
using (var bootstrapContainer = new CompositionContainer(catalog))
{
var myExportProvider = bootstrapContainer.GetExportedValue<IMyExportProvider>();
// create your real container and optionnally add catalogs (not shown here)
container = new CompositionContainer(myExportProvider);
}
}
You might also consider the problem from another angle. Do you really need to have imports in your custom ExportProvider? I do not know your requirements, but maybe you can make do without having imports.
As an alternative to the dual CompositionContainer solution, you could wire this up in a single export provider, and have it compose itself using the same container. As an example, I've defined the following contract and it's export:
public interface ILogger
{
void Log(string message);
}
[Export(typeof(ILogger))]
public class ConsoleLogger : ILogger
{
public void Log(string message)
{
Console.WriteLine(message);
}
}
And with my example ExportProvider, I expect to be able to import an instance of it:
public class TestExportProvider : ExportProvider
{
private readonly object _lock = new object();
private bool _initialised;
[Import]
public ILogger Logger { get; set; }
public void SetCompositionService(ICompositionService service)
{
if (service == null) throw new ArgumentNullException("service");
lock (_lock)
{
if (!_initialised)
{
InitialiseProvider(service);
}
}
}
private void InitialiseProvider(ICompositionService service)
{
service.SatisfyImportsOnce(this);
_initialised = true;
}
protected override IEnumerable<Export> GetExportsCore(ImportDefinition definition, AtomicComposition atomicComposition)
{
if (_initialised)
{
Logger.Log("Getting available exports for '" + definition.ContractName + "'");
// Do work here.);
return Enumerable.Empty<Export>();
}
return Enumerable.Empty<Export>();
}
}
I provide an instance of an ICompositionService, which CompositionContainer implements, and I perform a first-time initialisation when I call SetCompositionService. It checks to see if it has already been initialised, and if not, goes ahead and calls the SatisfyImportsOnce method on itself.
We would wire this up, something like this:
// Build our catalog.
var catalog = new AssemblyCatalog(typeof(Program).Assembly);
// Create our provider.
var provider = new TestExportProvider();
// Create our container.
var container = new CompositionContainer(catalog, provider);
// Register the composition service to satisfy it's own imports.
provider.SetCompositionService(container);
Obviously you wouldn't be able to use any imports and your ExportProvider will explicitly create for you, but for everything else, it should work.
I'm developing modular application and I'd like for entities from different modules to be able to register their own friendly url slugs.
app.UseMvc(routes =>
{
routes.Routes.Add(new SlugRouter(routes.DefaultHandler));
(...)
});
But following code throws Cannot access a disposed object. Object name: 'CommerceDbContext'. when trying to access slug from the repository.
public class SlugRouter : IRouter
{
private readonly IRouter _target;
public SlugRouter(IRouter target)
{
_target = target;
}
public async Task RouteAsync(RouteContext context)
{
var slugRepository = context.HttpContext.RequestServices.GetService<IRepository<SlugEntity>>();
// ERROR: Cannot access a disposed object. Object name: 'CommerceDbContext'
var urlSlug = await slugRepository.GetAllIncluding(x => x.EntityType).FirstOrDefaultAsync(x => x.Slug == context.HttpContext.Request.Path.Value);
(...)
}
It must be something simple I'm missing to be able to access the repository from router. Thanks for any help.
Begin a unit of work:
public async Task RouteAsync(RouteContext context)
{
var slugRepository = context.HttpContext.RequestServices.GetService<IRepository<SlugEntity>>();
var unitOfWorkManager = context.HttpContext.RequestServices.GetService<IUnitOfWorkManager>();
using (var uow = unitOfWorkManager.Begin())
{
var urlSlug = await slugRepository.GetAllIncluding(x => x.EntityType).FirstOrDefaultAsync(x => x.Slug == context.HttpContext.Request.Path.Value);
await uow.CompleteAsync();
}
}
Access IModel. You do not need dbContext for.
for entities from different modules to be able to register their own
friendly url slugs
I do it this way:
1) move OnModelCreating to static methiod
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
BuildModel(modelBuilder);
}
public static void BuildModel(ModelBuilder modelBuilder)
{
// ...
}
2) Create model where you need:
var conventionSet = new ConventionSet();
var modelBuilder = new ModelBuilder(conventionSet);
AdminkaDbContext.BuildModel(modelBuilder);
var mutableModel = modelBuilder.Model;
There is your meta (in mutableModel ). You can loop through entities (types of entities).
