Codefirst数据库没有创建
本文关键字:创建 数据库 Codefirst | 更新日期: 2023-09-27 18:13:53
我正在尝试创建一个实体框架代码优先环境的数据库。数据库中的表是标识表。
问题是SQL server的数据库创建。当我运行应用程序时没有创建数据库。
然而,我能够在这个位置找到物理发现-
C:'Users'user'AppData'Local'Microsoft'Microsoft SQL Server Data'SQLEXPRESS'HWAPI.mdf
所以每当我添加任何表或改变结构时,所有的变化都发生在上面的位置,并认为这不是使用主数据库。
我的本地SQL服务器没有创建数据库
看看我的代码-
StartUp.cs
public class Startup
{
public void Configuration(IAppBuilder app)
{
HttpConfiguration config = new HttpConfiguration();
ConfigureOAuth(app);
config.DependencyResolver = new NinjectResolver(NinjectWebCommon.CreateKernel());
WebApiConfig.Register(config);
app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
app.UseWebApi(config);
}
public void ConfigureOAuth(IAppBuilder app)
{
app.CreatePerOwinContext(OwinAuthDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
{
AllowInsecureHttp = true,
TokenEndpointPath = new PathString("/token"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),
Provider = new AuthorizationServerProvider()
};
}
}
还有上下文 -
public class OwinAuthDbContext : IdentityDbContext<ApplicationUser>, IDisposable
{
public OwinAuthDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
Database.SetInitializer<OwinAuthDbContext>(null);
}
public static OwinAuthDbContext Create()
{
return new OwinAuthDbContext();
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
modelBuilder.Entity<IdentityUser>().ToTable("AspNetUsers");
modelBuilder.Entity<IdentityRole>().ToTable("AspNetRoles");
modelBuilder.Entity<IdentityUserClaim>().ToTable("AspNetUserClaims");
modelBuilder.Entity<IdentityUserLogin>().ToTable("AspNetUserLogins");
}
protected override void Dispose(bool disposing)
{
base.Dispose(disposing);
}
}

</configuration>
如果需要额外的信息,请帮助我。
您的问题是连接字符串。您需要尝试如下所示。
如果需要使用Localhost,则:
<connectionStrings>
<add name="DefaultConnection" connectionString="Server=localhost; Database=HWAPI;Trusted_Connection=True;" providerName="System.Data.SqlClient" />
</connectionStrings>
如果需要使用LocalDb,则:
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDB)'v11.0;AttachDbFilename=|DataDirectory|'HWAPI.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
感谢大家的投入。
原来我需要为现有数据库设置凭据。在我为数据库设置凭据安全之后,它工作了。
before -
<add name="DefaultConnection" connectionString="Data Source=.'SQLEXPRESS;Initial Catalog=HWAPI;Integrated Security=SSPI;Connect Timeout=30;User Instance=True"
providerName="System.Data.SqlClient" />
后-
<add name="DefaultConnection" connectionString="Data Source=.'SQLEXPRESS;Initial Catalog=HWAPI;User ID=sa;Password=truw@123" providerName="System.Data.SqlClient"/>
这解决了我的问题,我能够连接到数据库内的SQLEXPRESS
