【问题描述】：
我收到此错误：[SqlException (0x80131904): Invalid object name 'dbo.UserRoles'.]，但我无法找到错误所在。我可以从其他表中检索其他数据，但不是这个。
条件是：
web.config 中的连接字符串：
<add name="myStoreConnection" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename='|DataDirectory|\myStore.mdf';Integrated Security=True" providerName="System.Data.SqlClient" />
上下文：
public class AdminMyStoreConnection : DbContext
{
public DbSet<UserRole> UserRoles { get; set; }
}
创建数据库的sql脚本：
CREATE TABLE [dbo].[UserRoles] (
[RoleId] INT IDENTITY (1, 1) NOT NULL,
[RoleName] NVARCHAR (256) NOT NULL,
PRIMARY KEY CLUSTERED ([RoleId] ASC),
UNIQUE NONCLUSTERED ([RoleName] ASC)
);
型号：
[Table("UserRoles")]
public class UserRole
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int RoleId { get; set; }
public string RoleName { get; set; }
}
带有索引视图的控制器：
private UsersContext db = new UsersContext();
public ActionResult Index()
{
return View(db.Customers.ToList());
}
查看：
@using myStore.Helpers
@model IEnumerable<myStore.Areas.Administrator.Models.UserRole>
@{
ViewBag.Title = "Roles management";
}
<h2>Roles management</h2>
<div class="admin-container">
<div class="bcontrol">
<a href="@Url.Action("Create", "Roles")" class="btn btn-large btn-primary"><i class="icon-plus-sign"></i> Create New Entry</a>
</div>
@{
var grid = new WebGrid(Model, defaultSort: "RoleId", canSort:true, canPage: true, rowsPerPage:20);
}
@grid.GetHtml(
tableStyle: "tadmin",
alternatingRowStyle: "alt",
selectedRowStyle: "selected-row",
columns:
grid.Columns(
grid.Column("RoleId",
header: "ID " + Html.SortDirection(ref grid, "RoleId"),
style: "tadmin-id"),
grid.Column("RoleName",
header: "Role Name " + Html.SortDirection(ref grid, "RoleName"),
format: @<text><a href="@Url.Action("Details", "Roles", new { id = item.RoleId })" >@item.RoleName</a></text>),
grid.Column("Control", style: "tadmin-control", canSort: false,
format:
@<text><a href="@Url.Action("Edit", "Roles", new { id = item.RoleId })" class="btn btn-large btn-primary"><i class="icon-edit"></i> Edit</a>
<a href="@Url.Action("Details", "Roles", new { id = item.RoleId })" class="btn btn-large btn-primary"><i class="icon-list"></i> Details</a>
<a href="@Url.Action("Delete", "Roles", new { id = item.RoleId })" class="btn btn-large btn-primary"><i class="icon-minus-sign"></i> Delete</a></text>)
)
)</div>

【问题讨论】：
-
只是好奇你的肯定它不存在于你的数据库中吗？
-
它已经存在并且有一些行
-
我建议让
Entity Framework通过package Manager Console构建您的database，而不是编写数据库脚本。此外，仅当Object表存在或不存在时才会发生错误。我假设您的 EF 正在尝试创建表。但它已经在那里了。 -
sql server 2008 我现在试试代码优先
