MVC学习笔记

1. CodeFirst生成数据库步骤
   webconfig配置
   

   <connectionStrings>
   <add name="AuthorDesignContext" providerName="System.Data.SqlClient" connectionString="Data Source=.;Initial Catalog=AuthorDesign;Integrated Security=False;User Id=sa;Password=123456;MultipleActiveResultSets=True" />
   </connectionStrings>

   <configSections>
       <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
       <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
     </configSections>

   包管理器

   程序包管理器控制台输入Enable-migrations
   然后输入add-migration AddDatabase（AddDatabase是数据库名）
   最后输入Update-Database

2. model字段验证
   

   /// <summary>
           /// 用户名
           /// </summary>
           [Required(ErrorMessage = "请输入用户名")]
           [StringLength(30, MinimumLength = 5, ErrorMessage = "请输入正确的用户名")]
           public string UserName { get; set; }
           /// <summary>
           /// 密码
           /// </summary>
           [Required(ErrorMessage = "请输入用密码")]
           [StringLength(30, MinimumLength = 5, ErrorMessage = "请输入正确的密码")]
           public string Password { get; set; }
           /// <summary>
           /// 验证码
           /// </summary>
           [Required(ErrorMessage = "请输入验证码")]
           [StringLength(6, MinimumLength = 6, ErrorMessage = "验证码错误")]
           public string ValidateCode { get; set; }
           /// <summary>
           /// 是否记住密码
           /// </summary>
           public bool IsRemind { get; set; }

   
   

   @model AuthorDesign.Web.Areas.Admin.Models.LoginModel

   //cshtml代码替换
   <input type="text" class="form-control" placeholder="用户名" />
   //替换
   @Html.TextBoxFor(m=>m.UserName,new { @class= "form-control",@placeholder="用户名" })
   
   //加入验证显示组件
   @Html.ValidationMessageFor(m => m.UserName);
