asp.net-mvc-4 – EF5.x中对PadLeft缺乏支持的任何解决方法？

我正在研究MVC4和Entity Framework 5中的应用程序,最近在执行查询时遇到了这个异常.

{“LINQ to Entities does not recognize the method ‘System.String PadLeft(Int32,Char)’ method,and this method cannot be translated into a store expression.”}

当我在过去遇到过类似的错误时,我只是在查询之外创建了一个变量,然后在LINQ语句中使用了该变量.不幸的是,在这种情况下,我正在操纵行结果,所以我不确定如何去做或如果这是最好的方法.任何帮助,将不胜感激.我的查询如下：

IQueryable<System.String> LEAPrograms = db.datamart_Draft
            .Where(where => where.snapshot_id == snapshot_id
                && !String.IsNullOrEmpty(where.entity_program))
            .Select(sel => (sel.entity_program.PadLeft(PROGRAMLENGTH,'0'))).distinct();

解决方法

这不是太优雅,但它做的工作：

...
.Select(sel => sqlFunctions.Replicate
                   ("0",PROGRAMLENGTH - sel.entity_program.Length)
             + sel.entity_program)

ASP.NET MVC 4 EF5与MySQL

所以我刚刚拿起了VS2012，我想要启动一个带有EF5的ASP.NET MVC 4应用程序。

我的主机没有MSsql，所以我必须使用MysqL。

如何告诉我的应用程序应该使用MysqL？ (我想要使用devart MysqL连接器或MysqL.com)

解决方法

您需要使用连接字符串DbProviderFactory和MysqL Connector 6.5.4的自定义DatabaseInitializer设置您的配置。我详细说明了 full step for getting EF5 and MySql to play,including code for the initializers on my blog.如果您需要ASP.Net会员提供程序解决方案，那么我将在 ASP.NET Membership/Role providers for MySQL?发布解决方案，同时提供完整的EF5 MysqL解决方案。

MysqL连接器当前不支持EF 5迁移，ASP.NET仅支持MS sql不是MysqL的SimpleMembership(MVC4默认值)。以下解决方案适用于Code First。

步骤是：

从NuGet抓住EF 5
>从NuGet(6.5.4)或MysqL(6.6.4)中抓取MysqL.Data和MysqL.Data.Entity
>配置MysqL数据提供程序
>配置MysqL连接字符串
>创建自定义MysqL数据库初始化程序
>配置自定义MysqL数据库初始化程序
>如果需要，请配置ASP.NET成员资格

DbProvider

<system.data>
 <DbProviderFactories>
  <remove invariant="MysqL.Data.MysqLClient"/>
  <add name="MysqL Data Provider" invariant="MysqL.Data.MysqLClient"
    description=".Net Framework Data Provider for MysqL" 
    type="MysqL.Data.MysqLClient.MysqLClientFactory,MysqL.Data" />
 </DbProviderFactories>
</system.data>

连接字符串

<connectionStrings>
  <add name="ConnectionStringName" 
    connectionString="Datasource=hostname;Database=schema_name;uid=username;pwd=Pa$$w0rd;" 
    providerName="MysqL.Data.MysqLClient" />
</connectionStrings>

数据库初始化程序

如果您使用NuGet(6.5.4)中的MysqL连接器，则需要自定义初始化程序。代码可在http://brice-lambson.blogspot.se/2012/05/using-entity-framework-code-first-with.html
或http://www.nsilverbullet.net/2012/11/07/6-steps-to-get-entity-framework-5-working-with-mysql-5-5/

然后将其添加到配置中

<configSections>
  <section name="entityFramework" 
    type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection,EntityFramework,Version=5.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089" />
</configSections>
<entityFramework>
  <contexts>
      <context type="Namespace.YourContextName,AssemblyName">
         <databaseInitializer 
           type="Namespace.YourChosenInitializer,AssemblyName">
         </databaseInitializer>
      </context>
    </contexts>
    <defaultConnectionFactory 
      type="MysqL.Data.MysqLClient.MysqLClientFactory,MysqL.Data" />
</entityFramework>

ASP.NET成员资格

<membership defaultProvider="MysqLMembershipProvider">
  <providers>
    <clear />
    <add name="MysqLMembershipProvider"
         type="MysqL.Web.Security.MysqLMembershipProvider,MysqL.Web,Version=6.5.4.0,PublicKeyToken=c5687fc88969c44d"
     autogenerateschema="true"
     connectionStringName="*NAME_OF_YOUR_CONN_STRING*"
     enablePasswordRetrieval="false"
     enablePasswordReset="true"
     requiresQuestionAndAnswer="false"
     requiresUniqueEmail="false"
     passwordFormat="Hashed"
     maxInvalidPasswordAttempts="5"
     minrequiredPasswordLength="6"
     minrequiredNonalphanumericCharacters="0"
     passwordAttemptwindow="10"
     passwordStrengthRegularExpression=""
     applicationName="/" />
  </providers>
</membership>

获取AccountController和Views工作：

>删除MVC 4 AccountController，AccountModels，帐户视图文件夹和_LoginPartial共享视图>创建一个新的MVC 3 Web应用程序>将MVC 3 AccountController，AccountModels，帐户视图文件夹和_logonPartial共享视图复制到您的MVC 4应用程序中>在@ Html.Partial(“_ logonPartial”)的共享_Layout视图中替换@ Html.Partial(“_ LoginPartial”)

ASP.NET MVC 中对 Model 进行分步验证的解决方法

在我之前的文章:ASP.NET MVC2.0 结合 WF4.0 实现用户多步注册流程中将一个用户的注册分成了四步，而这四个步骤都是在完善一个 Model 的信息，但是又分页面填写信息的，当时我加上 ModelState.IsValid 这句验证代码的时候，根本没法通过验证，因为在注册的前面三步，注册用户的 Model 信息都没填写完整，而 ModelState.IsValid 是对一个实体的所有属性进行判断验证的。当时很纠结，因为刚接触 Asp.net MVC，故没有找到解决方案。这篇文章将给出解决的办法。看下面需要验证的 Model 的代码如下：

代码

public class UserViewModel
{
[DisplayName( " step " )]
[Required(ErrorMessage = " You must select a step . " )]
public int Step { get ; set ; }
// 个人信息
[Required(ErrorMessage = " 姓名不能为空 " )]
[StringLength( 20 , ErrorMessage = " 姓名长度不能超过 20 个字符 " )]
public string Name { get ; set ; }

[RegularExssion( @" 120|((1[0-1]|\d)?\d) " , ErrorMessage = " 年龄格式不对 " )]
public int ? Age { get ; set ; }

// 职位信息
[Required(ErrorMessage = " 职位不能为空 " )]
public string Post { get ; set ; }
public int ? Salary { get ; set ; }

// 学历信息
[Required(ErrorMessage = " 毕业院校不能为空 " )]
public string University { get ; set ; }
public int ? GraduationYear { get ; set ; }

// 联系信息
[Required(ErrorMessage = " 邮件不能为空 " )]
[RegularExssion( @" ^[a-z][a-z|0-9|]*([_][a-z|0-9]+)*([.][a-z| " + @" 0-9]+([_][a-z|0-9]+)*)?@[a-z][a-z|0-9|]*\.([a-z] " + @" [a-z|0-9]*(\.[a-z][a-z|0-9]*)?)$ " , ErrorMessage = " 邮件格式不正确 " )]
public string Email { get ; set ; }
public int ? Mobile { get ; set ; }

public IEnumerable < SelectListItem > StepList { get ; set ; }

public UserViewModel()
{
var list = new List < SelectListItem > () {
new SelectListItem { Text = " (Select) " },
new SelectListItem { Value = " 1 " , Text = " Step1 " },
new SelectListItem { Value = " 2 " , Text = " Step2 " },
new SelectListItem { Value = " 3 " , Text = " Step3 " },
new SelectListItem { Value = " 4 " , Text = " Step4 " }
};
this .StepList = new SelectList(list, " Value " , " Text " );
}

}

实现：

这篇文章这种情况服务端和客户端的验证都会讲到。为了简化起见，这里我除去的 WF 的流程功能，直接用下拉框表示，当下拉框选择 step1 表示填写第一步注册的信息，当下拉框选择 step2 表示填写第二步注册的信息，当下拉框选择 step3 表示填写第三步注册的信息，当下拉框选择 step4 表示填写第四步注册的信息。写得很啰嗦，但是这个很容易实现，我使用 Jquery 来显示和隐藏下拉框对应的 Step。Jquery 代码如下：

代码

< script type = " text/javascript " >
$( function () {
$.fn.enable = function () {
return this .show().removeAttr( " disabled " );
}

$.fn.disable = function () {
return this .hide().attr( " disabled " , " disabled " );
}
var dllStep = $( " #Step " );
var step1 = $( " #Step1,#Step1 input " );
var step2 = $( " #Step2,#Step2 input " );
var step3 = $( " #Step3,#Step3 input " );
var step4 = $( " #Step4,#Step4 input " );
setControls();

dllStep.change( function () {
setControls();
});

function setControls() {
switch (dllStep.val()) {
case " 1 " :
step1.enable();
step2.disable();
step3.disable();
step4.disable();
break ;
case " 2 " :
step1.disable();
step2.enable();
step3.disable();
step4.disable();
break ;
case " 3 " :
step1.disable();
step2.disable();
step3.enable();
step4.disable();
break ;
case " 4 " :
step1.disable();
step2.disable();
step3.disable();
step4.enable();
break ;
case "" :
step1.disable();
step2.disable();
step3.disable();
step4.disable();
break ;
}
}
});
< / script>

如下图：

第一步：填写姓名和年龄。

第二步：填写职位和薪水

第三步填写：毕业院校和毕业时间

第四步填写：邮箱和电话

为了实现这样的验证，我们可以将验证的错误信息中移除不在当前步骤填写的字段的错误信息，写一个类 InputValidationModelBinder 继承 DefaultModelBinder 并重载 OnModelUpdated 方法，将不必要的错误信息清除，代码如下：

public class InputValidationModelBinder : DefaultModelBinder
{
protected override void OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var modelState = controllerContext.Controller.ViewData.ModelState;
var valueProvider = controllerContext.Controller.ValueProvider;

var keysWithNoIncomingValue = modelState.Keys.Where(x => ! valueProvider.ContainsPrefix(x));
foreach (var key in keysWithNoIncomingValue)
modelState[key].Errors.Clear();
}
}

上面是服务端的代码，对于客户端，我们都知道 asp.net MVC 客户端验证时通过 MicrosoftMvcValidation.js 去实现的。看下面代码。

1 validate: function Sys_Mvc_FormContext$validate(eventName) {
2 var fields = this .fields;
3 var errors = [];
4 for ( var i = ; i < fields.length; i ++ ) {
5 var field = fields[i];
6 if ( ! field.elements[ ].disabled) {
7 var thisErrors = field.validate(eventName);
8 if (thisErrors) {
9 Array.addRange(errors, thisErrors);
10 }
11 }
12 }
13 if ( this .replaceValidationSummary) {
14 this .clearErrors();
15 this .addErrors(errors);
16 }
17 return errors;
18 }
19 }

在第 6 行代码加入了一句判断：当页面的元素没有被 disabled 的时候才去验证。

好了这样就实现了一次只对 Model 中的几个属性字段进行验证。

运行：

asp.net mvc 的验证机制只对 model 中当前页面的属性进行验证：

填写正确通过验证：

总结：本文解决了我之前遗留下来的一个问题。实现了在 ASP.NET MVC 中对 Model 进行多步验证。希望对你有所帮助，如果你有更好的方法，欢迎给我留言。

asp.net – 在.NET中以编程方式添加HttpHandler的任何方法？

我一直在研究这一点，但没有遇到一个答案 – 有什么办法编程地添加一个HttpHandler到ASP.NET网站，而不添加到web.config？

解决方法

通过添加一个HttpHandler，我假设你的意思是配置文件

<system.web>
    <httpHandlers>...</httpHandler>
</system.web>

通过在请求期间直接添加IHttpHandler，可以自动控制它。所以在PostMapRequestHandler in the Application Lifecycle，你会做以下，在你自己的自定义IHttpModule：

private void context_PostMapRequestHandler(object sender,EventArgs e)
{
    HttpContext context = ((HttpApplication)sender).Context;
    IHttpHandler myHandler = new MyHandler();
    context.Handler = myHandler;
}

这将自动设置该请求的处理程序。显然，你可能想要包含一些逻辑来检查诸如动词，请求url等等，但这是如何做的。此外，这是多少流行的URL Rewriters工作，如：

http://urlrewriter.codeplex.com

不幸的是，使用pre built configuration handler that the web.config是隐藏的，似乎不可访问。它基于称为IHttpHandlerFactory的接口。

更新IHttpHandlerFactory可以像任何其他IHttpHandler一样使用，只能用作启动点而不是处理点。看到这篇文章。

asp.net-mvc – ASP MVC – 有默认内容类型的任何常量？

在框架中是否有所有 standard content types的一组常量？
