我想建立一个问卷调查MVC5项目。 我有一个MSSQL数据库,有几个表,如:Employee,Questions,Results ...
我创建了一个新的MVC5项目,我在我的数据库中添加了模型库,并且我管理所有需要它的CRUD操作。
现在我对问号进行了观察:
@model IEnumerable<ChestionarMVC.Models.FormQuestion>
@{
ViewBag.Title = "Chestionar";
}
<h2>Chestionar</h2>
@foreach (var item in Model)
{
@Html.Partial("_Chestionar",item)
}
<input id="Submit1" type="submit" value="submit" />
还有一个partialView显示每个问题,包含2个文本区域,一个用于答案,另一个用于某些附加信息:
@model ChestionarMVC.Models.FormQuestion
<table border="1" style="width:100%">
<tr>
<td>
@Html.DisplayFor(modelItem => Model.Question)
</td>
</tr>
<tr>
<td>
Raspuns <br />
<textarea id="TextArea1" rows="2" cols="80" style="width:800px; height:100px;"></textarea>
</td>
</tr>
<tr>
<td>
Document <br />
<textarea id="TextArea2" rows="2" cols="80" style="width:400px"></textarea>
</td>
</tr>
</table>
现在我想在tblResults中保存QuestionID,Answer和Document。 在webforms中我创建了一个usercontrol,然后我使用了Foreach usercontrol,并保存到数据库中。
在MVC中如何保存所有内容?
这是QuestionsModel:
namespace ChestionarMVC.Models
{
using System;
using System.Collections.Generic;
public partial class FormQuestion
{
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
public FormQuestion()
{
this.FormResults = new HashSet<FormResult>();
this.TBLPos = new HashSet<TBLPos>();
}
public int idQuestion { get; set; }
public string Question { get; set; }
public int idCategory { get; set; }
public int idPosition { get; set; }
public Nullable<int> Ordine { get; set; }
public virtual FormCategory FormCategory { get; set; }
public virtual Formular Formular { get; set; }
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
public virtual ICollection<FormResult> FormResults { get; set; }
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
public virtual ICollection<TBLPos> TBLPos { get; set; }
}
}
这是ResultsMOdel:
namespace ChestionarMVC.Models
{
using System;
using System.Collections.Generic;
public partial class FormResult
{
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
public FormResult()
{
this.Documentes = new HashSet<Documente>();
}
public int idResult { get; set; }
public int idUser { get; set; }
public int idQuestion { get; set; }
public string Answer { get; set; }
public string RefferenceDocument { get; set; }
public Nullable<System.DateTime> StampDate { get; set; }
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
public virtual ICollection<Documente> Documentes { get; set; }
public virtual Employee Employee { get; set; }
public virtual FormQuestion FormQuestion { get; set; }
}
}
这是问卷调查ActionResult用于生成调查问卷 - 视图:
public ActionResult Chestionar()
{
var formQuestions = db.FormQuestions;
return View(formQuestions.ToList());
}
答案 0 :(得分:1)
首先创建一个视图模型,其中包含视图所需的属性(请注意根据需要添加其他验证属性)
public class QuestionVM
{
public int ID { get; set; }
public string Question { get; set; }
[Required(ErrorMessage = "Please enter and answer")]
public string Answer { get; set; }
public string Document { get; set; }
}
然后创建EditorTemplate
。在/Views/Shared/EditorTemplates/QuestionVM.cshtml
@model QuestionVM
@Html.HiddenFor(m => m.ID)
@Html.HiddenFor(m => m.Question)
@Html.DisplayNameFor(m => m.Question)
@Html.DisplayFor(m => m.Question)
@Html.LabelFor(m => m.Answer)
@Html.TextAreaFor(m => m.Answer)
@Html.ValidationMessageFor(m => m.Answer)
... // ditto for Document (as for Answer)
在主视图中
@model IEnumerable<QuestionVM>
@using (Html.BeginForm())
{
@Html.EditorFor(m => m)
<input type="submit" ... />
}
请注意,EditorFor()
方法将根据模板为每个问题生成html,重要的是会添加正确的名称属性,使您的表单控件能够回发并绑定到模型
控制器中的
public ActionResult Chestionar()
{
// Get data model and map to view models
var model = db.FormQuestions.Select(q => new QuestionVM()
{
ID = q.idQuestion,
Question = q.Question,
Answer = .....,
Document = .... // see notes below
};
return View(model);
}
[HttpPost]
public ActionResult Chestionar(IEnumerable<QuestionVM> model)
{
if (!ModelState.IsValid)
{
return View(model);
}
// Get the data model again, map the view model properties back to the data model
// update properties such as user and date
// save and redirect
}
旁注:您的问题表明每个问题的(一个)答案和文档,但您当前的问题模型有一个集合(ICollection<FormResult> FormResults
),其中包含Answer
和{{1}的属性所以不清楚你是否想为每个问题添加多个答案和文档,或者只是一个。
