Users with different capabilities

阅读更多关于 Users with different capabilities

问题 I'm creating an ASP.Net MVC 5 application. In my website, 3 different types of users exist. Admin Normal users Restaurants Each of these users have its own capabilities and access rights. Meaning, the view for each of them should be different. I have created the models for both of the normal and restaurant. I was wondering how I can modify my existing structure to support this functionality. public class User : IUser { public User() : this(String.Empty) { } public User(string userName) {

Wait for form.submit() / POST to complete

阅读更多关于 Wait for form.submit() / POST to complete

问题 I'm stuck in a really bizarre situation here. It's complicated to explain but I'll try my best. Detailed explanation of the issue: On every top Nav click (Green donuts/circles), or next button, I must submit the form, if it exists and is valid. If not valid, form.valid() triggers validation errors and return false would stop any further propagation. This setup was working flawlessly until I noticed a strange behavior which isn't very persistence. Form on my 3rd tab, specifically, is quite

问题 I've been trying to get my feet wet with ASP.net MVC 5 for 2013, but so far I've failed to get even the most basic authentication working correctly. I've been reading around for the last few days and I finally stumbled upon (http://brockallen.com/2013/10/24/a-primer-on-owin-cookie-authentication-middleware-for-the-asp-net-developer/) which seemed to give the most basic simple example I could find. So I tried that, but it still fails to seem to actually create a session for the user. Here is

I am trying to call an Action from my view using @Html.Action("ActionName","controllerName") . But my page fails to load with below error: A single instance of controller 'Web.Areas.Area1.Controllers.ActionController' cannot be used to handle multiple requests.

Using ASP.NET Identity for a Role Provider easily

阅读更多关于 Using ASP.NET Identity for a Role Provider easily

I just spent the last two days researching and implementing the new ASP.NET Identity system with my existing database. More on that here: Integrating ASP.NET Identity into Existing DbContext . Now, I have a working UserStore and RoleStore , but I can't seem to figure out how to leverage them in my ASP.NET MVC 5 application without writing what seems like colossal amounts of code like in all the Identity samples that confuse me. There's two things I want to achieve: 1) use cookies to maintain the authorizations and 2) use roles to limit application access both in what is rendered in the views

阅读更多关于 Can't check in .mdf/.ldf in App_Data into TFS

问题 I am working with ASP.NET C# MVC 5. .mdf/.ldf files in App_Data do not appear on Pending Changes in team explorer. Therefore I can't check them into TFS(visual studio online). I've tried recreating the project a few times and none worked. What might be the cause for this? 回答1: Go to Team Explorer and locate Excluded Changes and you should find it excluded. Right click the App_Data folder and include it. But you might want to reconsider including the database files. As you're developing and

阅读更多关于 Setting Result in the context of ChallengeAsync method in an authentication filter

This question is related to the answer I have provided here . OP's comment got me thinking a bit. I suggested using a class implementing IHttpActionResult like this in the ChallengeAsync method of the authentication filter. public Task ChallengeAsync(HttpAuthenticationChallengeContext context, CancellationToken cancellationToken) { context.Result = new ResultWithChallenge(context.Result); return Task.FromResult(0); } public class ResultWithChallenge : IHttpActionResult { private readonly IHttpActionResult next; public ResultWithChallenge(IHttpActionResult next) { this.next = next; } public
