[英]How to insert data and return inserted identity with Dapper in MVC?
I have a model Products like this, 我有这样的模型产品,
public int ProductID { get; set; }
public int ProductDetailsID { get; set; }
public int ProductStatusID { get; set; }
public string ProductName { get; set; }
public int Priority { get; set; }
public DateTime LastProcessedDate { get; set; }
public DateTime CreatedDate { get; set; }
public DateTime ModifiedDate { get; set; }
public bool Enabled { get; set; }
Here is my view, 这是我的看法,
@model MVCApplication1.Models.Products
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
@using (Html.BeginForm())
{
<div class="form-horizontal">
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
@Html.HiddenFor(i => i.ProductDetailsID, new { @Value = ViewBag.ProductDetailsID })
<div class="form-group">
@Html.LabelFor(i => i.Name, "Product Name ", new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(i => i.Name, new { @class = "form-control" })
@Html.ValidationMessageFor(i => i.Name, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(i => i.Enabled, "Enabled ", new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.CheckBoxFor(i => i.Enabled, new { @class = "checkbox", @checked = "checked" })
@Html.ValidationMessageFor(i => i.Enabled)
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</div>
</div>
}
Here is my controller, 这是我的控制器,
[HttpPost]
public ActionResult Create(Products model)
{
try
{
if (ModelState.IsValid)
{
model.LastProcessedDate = DateTime.Now;
model.CreatedDate = DateTime.Now;
model.ModifiedDate = DateTime.Now;
model.ProductStatusID = 0;
int id = con.Query<int>("ProductInsert", model, commandType: CommandType.StoredProcedure).Single();
return Content("Product added successfully..!!", "text/plain");
}
}
catch (Exception)
{
throw;
}
return View();
}
And here is my sql code, 这是我的sql代码,
CREATE PROCEDURE [dbo].[ProductCreate]
(
@ProductDetailsId INTEGER,
@ProductStatusID INTEGER,
@ProductName VARCHAR(255),
@Priority INTEGER,
@LastProcessedDate DATETIME,
@CreatedDate DATETIME,
@ModifiedDate DATETIME,
@Enabled BIT
)
AS
INSERT INTO dbo.Products (ProductDetailsId, ProductStatusId, Product, Priority, LastProcessedDate, CreatedDate, ModifiedDate, Enabled, ScheduleTypeId, Server, RetryNumber, Message)
VALUES(@ProductDetailsId, @ProductStatusId, @ProductName, @Priority, @LastProcessedDate, @CreatedDate, @ModifiedDate, @Enabled)
SELECT SCOPE_IDENTITY() AS ProductID
I am getting "procedure or function ProductCreate has too many arguments specified" error. 我得到“过程或函数ProductCreate指定了太多参数”错误。
What am I doing wrong? 我究竟做错了什么?
When you call a stored procedure, dapper has no good way of knowing what members should be treated as parameters. 当您调用存储过程时,dapper无法知道哪些成员应被视为参数。 With regular tsql, it can have a stab at "obviously not used", " obviously used", "maybe" - but dapper does not choose to pay the extra cost of asking the database what your stored procedure looks like all the time. 对于常规的tsql,它可能会“明显不使用”,“明显使用”,“可能” - 但是dapper并没有选择支付额外的费用来询问数据库您的存储过程一直是什么样子。 I suspect it is adding properties that aren't used - ProductId
in particular. 我怀疑它正在添加未使用的属性 - 特别是ProductId
。 Help it out by mapping to an anon type. 通过映射到anon类型来帮助它。 Instead of passing model
, pass: 传递:而不是传递model
new { model.ProductDetailsId, model.ProductStatusID, ...todo... ,
model.Enabled }
