I do not understand why my code does not work. I have a model:
public class Client
{
public int Id { get; set; }
public string Surname { get; set; }
}
I have a Context:
public class BetContext : DbContext
{
public BetContext()
: base("name=Bet")
{
}
public virtual DbSet<Client> Clients { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}
}
My ConnectionString:
<connectionStrings>
<add name="Bet" providerName="System.Data.SqlClient" connectionString="Data Source=PK01; Initial Catalog=Bet;Integrated Security=True; MultipleActiveResultSets=True" />
</connectionStrings>
My GlobalAsax:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory());
Database.SetInitializer(new InitializerDb());
}
My ConnectToServer:
ConnectToServer
My Initializer:
public class InitializerDb : DropCreateDatabaseIfModelChanges<BetContext>
{
protected override void Seed(BetContext context)
{
var client = new List<Client>
{
new Client
{
Id = 1 , Surname = "Lalala" , Name = "Paxan" , DateOfBirthday = DateTime.Now, Email = "lalll",
Password = "123445" , Phone = "12345"
}
};
client.ForEach(s => context.Clients.Add(s));
context.SaveChanges();
}
}
I am stuck. Please tell me why this code is not creating a new database in SQL Server?

I am working on an intranet site with Windows Authentication for logins. However, I want to extend the IPrincipal to have other properties. For instance, I'd like to get the user's FirstName in #User.FirstName or User.AuthorizedActivity("Admin/Permissions/Edit") (would retrieve from db) using activities instead of roles to hide certain links, etc. I am really having a heck of a time figuring this out over the past 2 days and find much information doing this with Windows Authentication.
My CustomPrincipal and BaseViewPage setup:
namespace Intranet_v2.Helpers
{
public interface ICustomPrincipal : IPrincipal
{
Guid UserGuid { get; set; }
string FirstName { get; set; }
string LastName { get; set; }
string FullName { get; set; }
}
public class CustomPrincipal : ICustomPrincipal
{
public IIdentity Identity { get; private set; }
public bool IsInRole(string role) { return false; }
public CustomPrincipal(string identity)
{
this.Identity = new GenericIdentity(identity);
}
public Guid UserGuid { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string FullName { get; set; }
}
public class CustomPrincipalSerializeModel
{
public Guid UserGuid { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string FullName { get; set; }
}
public class BaseController : Controller
{
protected virtual new CustomPrincipal User
{
get { return HttpContext.User as CustomPrincipal; }
}
}
public abstract class BaseViewPage : WebViewPage
{
public virtual new CustomPrincipal User
{
get { return base.User as CustomPrincipal; }
}
}
public abstract class BaseViewPage<TModel> : WebViewPage<TModel>
{
public virtual new CustomPrincipal User
{
get { return base.User as CustomPrincipal; }
}
}
}
Views Web.Config BaseViewPage:
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

I think my main problem is I have no idea what to do in the protected void Application_PostAuthenticateRequest(object sender, EventArgs args) for my Global.asax.cs file. I have a poor attempt at setting it up here:
protected void Application_PostAuthenticateRequest(object sender, EventArgs args)
{
//var application = (HttpApplication)sender;
var context = application.Context;
if (context.User != null || !context.User.Identity.IsAuthenticated) return;
var formsIdentity = (FormsIdentity)context.User.Identity;
if (formsIdentity == null) return;
var ticket = formsIdentity.Ticket;
JavaScriptSerializer serializer = new JavaScriptSerializer();
CustomPrincipalSerializeModel serializeModel = serializer.Deserialize<CustomPrincipalSerializeModel>(ticket.UserData);
CustomPrincipal newUser = new CustomPrincipal(ticket.Name);
newUser.UserGuid = serializeModel.UserGuid;
newUser.FirstName = serializeModel.FirstName;
newUser.LastName = serializeModel.LastName;
newUser.FullName = serializeModel.FullName;
var values = ticket.UserData.Split('|');
var roles = values[1].Split(',');
context.User = new GenericPrincipal(new GenericIdentity(ticket.Name, "Forms"), roles);
}
Now I'm at the point where #User.Name is now null. I'm in way over my head on this. Any help is appreciated. My protected void Application_PostAuthenticateRequest(object sender, EventArgs args) is completely out of wack.
All I want to do is rely on Windows Authentication to do what it does normally and add a few extra properties to the HttpContext.Current.User. Any help is appreciated... I can't be the only one trying to do this.
What I normally do is just request the additional user information later. For instance, using an Extension method like:
public static class PrincipalExtensions
{
private static void Initialize(string userName)
{
var userRecord = //Get user information from DB;
var session = HttpContext.Current.Session;
if (session != null)
{
session.Add("UserID", userRecord.ID);
session.Add("UserEmail", userRecord.Email);
//And so on
}
}
public static long? GetUserID(this IPrincipal user)
{
var id = HttpContext.Current.Session["UserID"] as long?;
if (id == null)
Initialize();
return (long)HttpContext.Current.Session["UserID"];
}
}
This is roughly what I implement in some of my projects; rather than tapping into the login process and store it in the cookie, the system can lazy load the information and cache in session when the information is needed.
I am trying to connect oracle with MVC as below
Config file
<connectionStrings>
<add name="OracleDbContext" providerName="Oracle.ManagedDataAccess.Client" connectionString="User Id=test;Password=123_test;Data Source=local:xxxx/liveprod" />
</connectionStrings>
User table model
public class sys_users
{
[Key]
public long us_id { get; set; }
public string us_name { get; set; }
public string us_pass { get; set; }
}
Db context
public class OracleDBContext : DbContext
{
public OracleDBContext()
: base("name=OracleDbContext")
{
}
public virtual DbSet<sys_users> sys_users { get; set; }
}
Controller
public ActionResult Login(string Name, string Password)
{
var u = db.sys_users.Where(d => d.us_name.Equals(Name) && d.us_pass.Trim().Equals(Password)).FirstOrDefault();
if (u != null)
{
Session["LoggedInAdminUserId"] = u.us_id.ToString();
Session["LoggedInAdminUsername"] = u.us_name.ToString();
return RedirectToAction("Login");
}
else
{
ViewBag.message = "Username or Password is invalid.";
}
return View();
}
But at the line
var u = db.sys_users.Where(d => d.us_name.Equals(Name) && d.us_pass.Trim().Equals(Password)).FirstOrDefault();
I am getting error
ORA-01918: user 'dbo' does not exist
Do I need to do anything else for using oracle tables as model in MVC??
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
//Configure default schema
modelBuilder.HasDefaultSchema("STORE");
}
Entity default schema user is based on Sql (dbo) change the default to anything else but in UPPERCASE
I am in the process of Downgrading from EF7 to EF6 due to business decisions. I have looked at several examples but cannot seem to get it to work.
Here is what I have for EF 7
Context:
public class OwnerContext : DbContext
{
protected override void OnConfiguring(DbContextOptionsBuilder options)
{
options.UseSqlServer(#"Server=server\testdbs;Database=test;Trusted_Connection=True;");
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Owner>(entity =>
{
entity.ToTable("Owner");
entity.Property(e => e.Id)
.HasMaxLength(50)
.HasColumnType("varchar");
});
}
public virtual DbSet<Owner> Owner { get; set; }
}
Owner Model
public class Owner
{
public int OwnerId { get; set; }
public string Name { get; set; }
public int Age { get; set; }
}
How I use it
static void Main(string[] args)
{
using (var context = new OwnerContext())
{
var owner = new Owner
{
Name = "First Name",
Age = 4
};
context.Owner.Add(owner);
context.SaveChanges();
Console.ReadLine();
}
}
I got this to work with no issues and I get records in the data base. For EF 6 it is a little different
Here is what I have for EF6
Context
public class OwnerContext : DbContext
{
public OwnerContext(string connectionString) : base(connectionString) { }
public OwnerContext()
: this("OwnerConn")
{
}
public virtual DbSet<Owner> Owner{ get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
var owner = modelBuilder.Entity<Owner>().ToTable("Owner");
owner.Property(e => e.OwnerId)
.HasMaxLength(50)
.HasColumnType("varchar");
owner.HasKey(u => u.OwnerId);
}
}
Model
public class Owner
{
public int OwnerId { get; set; }
public string Name { get; set; }
public int Age { get; set; }
}
How I use it
static void Main(string[] args)
{
try
{
using (var context = new OwnerContext())
{
var person = new Owner
{
Name = "Test Name",
Age = 5
};
context.Owner.Add(person);
context.Entry(person).State = EntityState.Added;
context.SaveChanges();
}
}
catch (Exception exception)
{
Console.WriteLine(exception.Message);
}
Console.ReadLine();

ConnectionString

It seems to be very simple based on the tutorials. Hoever, I cant seem to get the changes to be reflected in the database. However, when I restart the console app and pull the records like this.
var rows = from a in context.Owner select a
It returns rows but I still don't see them in the DB. I'm out of ideas so hopefully someone can help.
I try to implement a basic web site that uses EF in ASP.NET MVC. Simply put, I try to connect SQL database and list them. I have a Product model. However, nothing comes to the screen. Here is my Product class:
public class Product
{
public int ProductID { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public decimal Price { get; set; }
public string Category { get; set; }
}
A repository pattern has been used in the Project. So interface IProductRepository here:
public interface IProductRepository
{
IQueryable<Product> Products { get; }
}
Here is the Product Controller in the project. It is the only controller in entire solution:
public class ProductController : Controller
{
private IProductRepository repository;
public ProductController(IProductRepository productRepository)
{
this.repository = productRepository;
}
public ViewResult List()
{
//This is not the part of the original project. In order to make sure that the code interacts with
//the database.
if (repository.Products.Count() == 0)
{
NinjectControllerFactory nin = new NinjectControllerFactory();
IKernel kernel = nin.GetNinjectKernel();
this.repository = kernel.Get<IProductRepository>();
}
return View(repository.Products);
}
}
Default route has been set there. Here is the content of the List.cshtml
#model IEnumerable<Model.Product>
#{
ViewBag.Title = "List";
}
<h2>List</h2>
#foreach (var p in Model)
{
<div class="item">
<h3>#p.Name</h3>
#p.Description
<h4>#p.Price.ToString("c")</h4>
</div>
}
I connect to my local database, define a table, populate it. I inserted connection string to the web.config of the project:
add name="EFDbContext" connectionString="Data
Source=(localdb)\v11.0;Initial Catalog=efver1;Integrated
Security=True" providerName="System.Data.SqlClient"
Here is the EFProductRepository.cs
public class EFProductRepository : IProductRepository
{
private EFDbContext context = new EFDbContext();
public IQueryable<Product> Products
{
get { return context.Products; }
}
}
and here is the EFDbContext.cs:
public class EFDbContext : DbContext
{
public DbSet<Product> Products { get; set; }
}
I am using Ninject as a dependency injector. Here it is :
public class NinjectControllerFactory : DefaultControllerFactory
{
private IKernel ninjectKernel;
public NinjectControllerFactory()
{
ninjectKernel = new StandardKernel();
AddBindings();
}
protected override IController GetControllerInstance(RequestContext
requestContext, Type controllerType)
{
return controllerType == null
? null
: (IController)ninjectKernel.Get(controllerType);
}
private void AddBindings()
{
ninjectKernel.Bind<IProductRepository>().To<EFProductRepository>();
}
public IKernel GetNinjectKernel()
{
return this.ninjectKernel;
}
}
I made necessary changes here:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
//Burası da önemli.
ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory());
}
However, only page I can see is a blank screen as follows :
What I am missing here? thanks in advance.
edit 1:
Here is the data inside local database:
add name="EFDbContext" connectionString="Data Source=(localdb)\v11.0;Initial Catalog=efver1;Integrated Security=True" providerName="System.Data.SqlClient"
You are not connecting to the right database. According to the screenshot, your data is in INT-0014\SQLEXPRESS, not (localdb)\v11.0.
I am using code first EF and new to this framework. I am trying to create a database using Database.SetInitializer but it looks like I need SQL Server Express. But I have to create database in SQL Server 2014. How to do this?
Can anybody explain this with the example from EF-dbcontext book which has following classes.
public class BreakAwayContext : DbContext
{
public DbSet<Destination> Destinations { get; set; }
public DbSet<Lodging> Lodgings { get; set; }
public DbSet<Trip> Trips { get; set; }
public DbSet<Person> People { get; set; }
public DbSet<Reservation> Reservations { get; set; }
public DbSet<Payment> Payments { get; set; }
public DbSet<Activity> Activities { get; set; }
}
class Program
{
static void Main(string[] args)
{
Database.SetInitializer(new InitializeBagaDatabaseWithSeedData());
try
{
using (var context = new BreakAwayContext())
{
foreach (var destination in context.Destinations)
Console.WriteLine(destination.Name);
}
}
catch(Exception ex){
Console.WriteLine(ex.ToString());
}
Console.Read();
}
}
public class InitializeBagaDatabaseWithSeedData : DropCreateDatabaseAlways<BreakAwayContext>
{
protected override void Seed(BreakAwayContext context)
{
context.Destinations.Add(new Destination
{
Name = "Hawaii",
Country = "USA",
Description = "Sunshine, beaches and fun."
});
context.Destinations.Add(new Destination
{
Name = "Wine Glass Bay",
Country = "Australia",
Description = "Picturesque sandy beaches."
});
}
Set your connection string in your constructor:
public class BreakAwayContext : DbContext
{
public BreakAwayContext()
: base("MyConnectionString", throwIfV1Schema: false)
{
}
...
Then set your connection string in web.config or app.config:
<connectionStrings>
<add name="MyConnectionString" connectionString="Data Source=servername;Initial Catalog=dbname;..." providerName="System.Data.SqlClient" />
</connectionStrings>
