I am trying to use Microsoft.AspNetCore.OData, v7.0.0.0-beta1, in a simple project.
I am failing to filter, select, and use top or skip.
Overriding the ValidateQuery of the EnableQueryAttribute, I can successfully perform these type of operations so I believe the library is buggy.
I could not find the right channel to report the issue, can anyone help?
The sample code to reproduce is available here: https://github.com/norcino/AspNetCoreSamples/tree/master/SampleODataApp
The solution to the problem was the actual initialization of the MVC route builder.
Like in the .net framework version it is possible to specify which operation is allowed for OData query. In the example below I am whitelisting everything but you can do a more fine tuning passing an instance of QueryOptionSetting.
app.UseMvc(routeBuilder =>
{
routeBuilder
.Select()
.Expand()
.Filter()
.OrderBy(QueryOptionSetting.Allowed)
.MaxTop(2000)
.Count();
routeBuilder.EnableDependencyInjection();
});
Note that, the attribute [HttpGet, EnableQuery(AllowedOrderByProperties = "Id")], will effectively enforce the order by to the sole Id property specified in the attribute, but first you need to enable all from the configuration.
I'm new to ASP.NET Core and trying to build web api with Openiddict for security, what I'm looking for is a way to implement my own UserStore and other stores and use them ?
Is there an easy sample or example to follow ?
I tried to implement IUserStore and add it to IServiceCollection and used AddUserStore<MyUserStore>().
When I'm trying to execute identityUserManager.CreateAsync(user,..) I'm getting the following error.
The entity type
'Microsoft.AspNetCore.Identity.EntityFrameworkCore.IdentityUserLogin'
requires a primary key to be defined
I think the user class I'm creating and because it's inheriting from IdentityUser which is in Microsoft.AspNetCore.Identity.EntityFrameworkCore, causing this problem, now I didn't find another IdentityUser in another name space two inherit from, isn't there any ?
I'm using mvc.jquery.datatables with Asp.Net MVC 4 and DataTables
It works fine and as expected.
When I introduce T4 MVC to replace MVC magic strings, T4 MVC does not like the return type that mvc.jquery.datatables wants me to use in my Ajax action method.
The return type is:
DataTablesResult<MyType>
T4 MVC does not like this and responds with the error:
The type 'Mvc.JQuery.Datatables.DataTablesResult <TSource> ' has no constructors defined T4MVC.cs
So, how can I get T4 MVC and mvc.jquery.datatables to play ball, and at worst, can I get T4 MVC to ignore that one action?
I don't think there is a great way to ignore specific actions, though it would make sense to add that.
I think that if you were to add a [Obsolete] attribute on it, it would get ignored, though clearly that's a hack. If you look in ProcessControllerActionMethods in t4mvc.tt, you'll see the various conditions that cause actions to get ignored.
If you want to tackle creating a new attribute to ignore actions, we can take this to https://t4mvc.codeplex.com/. Or potentially it can be smarter and auto detect this situation.
I have a custom authorization attribute, required only for some actions, which checks the request headers for a custom token. The token is checked in a database. Checking the database requires access to a service which I would like to have injected through the constructor.
The way I have read this can be done (here, here, and here) is by having a constructor-less filter and injecting the dependent one like this:
kernel.BindFilter<MyAuthorizeFilter>(FilterScope.Controller, 0).WhenControllerHas<MyAuthorizeAttribute>();
However the BindFilter method is not available to me as I have setup Ninject as described here. This is using Ninject.Web.Common instead of Ninject MVC3 as I read that Ninject MVC3 would not work with MVC4 RC. How else can I go about accomplishing this?
I have read also that I could add to GlobalFilters.Filters - however I don't want it to be present on every action.
Thanks in advance for any answers.
I'm not completely sure I see how you have set up your application, but my experience has been that if you want a filter for a WebApi controller you need to add it to the HttpFilterCollection that is available from the GlobalConfiguration.Filters. This is a Different set of filters than what MVC uses (through the GlobalFilterCollection).
Clarified Updated Question - Start
In the official MVC 3 Getting Started-tutorial it seems to me that all we have to do to get ORM working are two steps.
First adding the simple MovieDBContext-code as described at the end of part 4 ..
public class MovieDBContext : DbContext
{
public DbSet<Movie> Movies { get; set; }
}
.. and second in the beginning of part 5, with a simple right-click on the Controllers folder we can auto-generate a MoviesController that implements CRUD()-functionality using Entity Framework by simply telling which Model to use.
Now when using the web-application we can already write and read from the database.
What would be the simplest (or a simple) way to get this done for our Movie-Model with NHibernate instead of using Entity Framework?
Clarified Updated Question - End
Original question (only for additional background-info):
I'm trying to create an ASP.Net MVC 3 application that uses NHibernate and Postgres.
Background Info
Development is done on Windows with Visual Web Developer Express, the production environment will be/should be Linux+Mono.
Steps that have worked so far:
An ASP.Net Dynamic Data Entities Web Application using Npgsql and Postgres as the DB.
Successfully run on Windows development machine.
(Following this tutorial)
An ASP.Net MVC 3 application without using a database/model yet:
Succesfully run on Windows development machine and deployed to Linux production environment using Mono and Nginx. (Only as a proof of concept for myself not as a web app used by the public.)
An ASP.Net MVC 3 application with a model using SQL Server Express as the DB.
Successfully run on my Windows development machine.
(Following the MVC 3 Getting Started-tutorial)
Question
So far I managed to get Postgres to work with a "Dynamic Data Entities Web Application" but with an MVC 3 Web app I'm stuck on where/how to start. For the last mentioned MVC-3-Movie-Webapp I want to switch the DB from SQL Server Express to Postgres using NHibernate and Npgsql (NHibernate since Mono doesn't support Entity Framework).
When you look at the end of part 4 there's the simple MovieDBContext-code
public class MovieDBContext : DbContext
{
public DbSet<Movie> Movies { get; set; }
}
and in the beginning of part 5, we autogenerate CRUD-stuff using Entity Framework by simply telling which Model to use.
(MoviesController.cs, Create.cshtml, Delete.cshtml, Details.cshtml, Edit.cshtml, and Index.cshtml)
So I have that working with Entity Framework and SQL Server Express, but how would I achieve the same result by using NHibernate? (doesn't have to be with postgres immediately, sticking with SQL-Server as a first step would be fine) (Hopefully with similar simplicity, but getting the result itself would be great)
I found a lot of old stuff and how I would manually map things, but what would be a good-up to date standard way of achieving this with NHibernate for MVC 3?
(The closest thing I found was the source code mentioned in this thread, but it's 64 MB unzipped I got several "Projects not loaded successfully"-errors and the author said he uses MVC 2 so I think it's a little over my head for being a complete NHibernate noob.)
I think showing how this is done could be very useful for others as well, since the original tutorial is very easy to follow and is linked as the official starting point for MVC 3 app-development on http://www.asp.net/mvc ("Your First ASP.NET MVC App").
So I think this would be a great up to date example about how to use NHibernate with MVC 3.
Actually, those automated things haven't helpful enough in real world applications. We have to separate concerns and by using DataContext in UI Layer is not a good practice because that dependency will cause problems like lack of test-ability, violation of best practices. I think you need to have following things of your project
Separation of Concern (Layered Architecture - UI Layer, Servie Layer, Domain Layer, Infrastructure Layer)
Generic Repository and Unit of Work wrapping (Database functionalities, ORM - EF, NHibernate, etc
In your Service Layer process repositories and unit of work processings and expose Data Transfer objects or your domain objects (POCOs) to UI Layer
Use IOC to inject dependencies will help you to minimize dependencies
Create Unit test and Integration tests
Use Continuous Integration and Source control prefer (Distributed: Mercurial)

NuGet is your friend. Here's a good example of using NuGet to automatically wire in your dependencies and configuration pretty much automatically.
Hope this helps.
Suggestion, don't get hung up on all the automatic stuff that the tutorials are showing you. Microsoft is just trying to show that you can easily get things started if you don't try to do anything unique.
Now for your situation. When you're making a controller, you're wanting to bind that controller with a type of model that you created somewhere. With nHibernate I'm thinking that you'll have manually created these POCO's and that you're using one of the many ways to map those POCO's through nHibernate to your database.
You won't be able to use the Entity Framework options because they're depending upon the features of the framework to provide information on the object, database, etc. Easiest things is to just make a controller that either gives you the options for CRUD or use an empty controller to build up your own ActionResults.
Hope this helps some and good luck with your project.
