无效的对象名称'dbo.UserRoles'

Question

我收到此错误:[SqlException(0x80131904):无效的对象名称'dbo.UserRoles'.],但我无法捕获错误的位置.我可以从其他表中检索其他数据,但不是这样.

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" />

背景:

public class AdminMyStoreConnection : DbContext
    {
        public DbSet<UserRole> UserRoles { get; set; }
    }

用于创建数据库的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)
);

模型:

[Table("UserRoles")]
public class UserRole
{
    [Key]
    [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
    public int RoleId { get; set; }
    public string RoleName { get; set; }
}

带索引视图的控制器:

private UsersContext db = new UsersContext();
public ActionResult Index()
{
    return View(db.Customers.ToList());
}

视图:

@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>&nbsp;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>&nbsp;Edit</a>
                        <a href="@Url.Action("Details", "Roles", new { id = item.RoleId })" class="btn btn-large btn-primary"><i class="icon-list"></i>&nbsp;Details</a>
                        <a href="@Url.Action("Delete", "Roles", new { id = item.RoleId })" class="btn btn-large btn-primary"><i class="icon-minus-sign"></i>&nbsp;Delete</a></text>)
                 )

        )</div>    

和错误消息:

Answer 1

遗憾的是这个问题非常简单 - 因为我有2个区域 - 主要和管理员,我分别有2种类型的数据连接,我在webconfig中只有1个连接字符串.在我为管理上下文添加第二行之后,所有工作都要感谢注意)因此webconfig中的问题是不完整的(错误配置)

Answer 2

这通常仅仅意味着配置问题

• 也许真的没有这样的表
• 也许该表在那里，但不是 dbo 方案
• 也许数据库区分大小写（确保两个表名拼写正确
