我们来制作 题目的新增

后台绑定编辑器

  • 不绑定，通过自己写的编辑器好了，修改的时候样式不对拉。
  • 生成表的表单页面

  • 表单内容修改 ``` @model LDSTiMu @using XCode.Membership @using NewLife; @using NewLife.Web; @using XCode; @using XCode.Configuration; @using XCode.Membership; @using NewLife.Cube; @{ var entity = Model; var fields = ViewBag.Fields as IList; var isNew = (entity as IEntity).IsNullKey; }
@Html.TextBox(“TestNumbers”, @entity.TestNumbers, new { @class = “form-control”, role = “number” })
@Html.TextBox(“ErrorNumbers”, @entity.ErrorNumbers, new { @class = “form-control”, role = “number” })
@Html.TextBox(“CreateTime”, @entity.CreateTime.ToFullString(“”), new { @class = “form-control date form_datetime” })
@Html.TextBox(“UpdateTime”, @entity.UpdateTime.ToFullString(“”), new { @class = “form-control date form_datetime” })

@await Html.PartialAsync(“_Form_Footer”, entity) @if (this.Has(PermissionFlags.Insert, PermissionFlags.Update)) {

}

  11. - 后台

public IActionResult NewTiMuList(PageParameter page) { ///取前二十条记录 var xxx = LDSTiMu.FindAll(null,null,null,0,20); if (xxx!=null) { return View(xxx); }; return View( ); }

<a name="bVubq"></a>
# 新增题目方法

- 先写GET方法 ，要读单元表
- 将学科进行GROUP BY送前台
- 同时对单元表单元和学科送前台
-   后台方法 
- 这里使用了一个DLSXueKeDanYuan.cs,我是放在MODELS下面的。

using System; using System.Collections.Generic; using System.Linq; using System.Threading.Tasks;

namespace dqltest.Models { public class DLSXueKeDanYuan { public string SubjectName { get; set; }

    public string Unit { get; set; }

}

}


- 后台GET方法

/// [HttpGet] public IActionResult ADDTiMu( ) { ///读出所有的单元表 ///这一页有三个选择 按学科单元进行处理,将这二个字段读出来，然后送到新的MODEL中去到前台 var dal = DAL.Create(“Membership”); string selectstring = “select SubjectName,Unit FROM LDSTiMu group by SubjectName,Unit ;”; var db = dal.Query(selectstring); var course = LDSTiMu.LoadData(db); ///将这个两列copy到新表 var mmm = course.Select(s => { var m = new DLSXueKeDanYuan(); m.Copy(s); return m; }).ToList(); ViewBag.xuekedanyuan = mmm; var mmmmmm= mmm.GroupBy(x => x.SubjectName); ViewBag.SubjectName = mmmmmm; return View( ); }

 前台设置

@model XCode.Membership.LDSTiMu

@{

}

效果<br />后台代码

[HttpPost] [ValidateAntiForgeryToken] public IActionResult ADDTiMu(LDSTiMu addtimu) { if (ModelState.IsValid) { var enreading1 = new LDSTiMu { SubjectName = addtimu.SubjectName, Unit = addtimu.Unit, SubjectExplain = addtimu.SubjectExplain, SubjectText = addtimu.SubjectText, SubjectType = addtimu.SubjectType, Analysis = addtimu.Analysis, OptionA = addtimu.OptionA, OptionB = addtimu.OptionB, OptionC = addtimu.OptionC, OptionD = addtimu.OptionD, Answers = addtimu.Answers, Bei1 = addtimu.Bei1, TestNumbers = 1, ErrorNumbers = 0 }; enreading1.Insert(); return RedirectToAction(nameof(NewTiMuList)); } return View(); } ``` 然后新增成功会跳转
