mvc中的复选框，显示每个客户的复选框 [英] checkbox in mvc, display a checkbox for each customer

问题描述

mvc中的复选框有问题。新编码，但我创建了一个数据库第一个MVC4项目。在我的一个视图中，我想为每个客户显示一个复选框，当选中并按提交时，数据库表应该更新为true，意味着产品已分派。如果有人可以看到解决方案或有一个很好的教程复选框，请告诉我。提前致谢！

Having trouble with checkbox in mvc. New to coding, but I have created a database first MVC4 project. In one of my views I want to display a checkbox for each customer, when checked and submit pressed the database table should update to true meaning product dispatched. If anyone can see the solution or has a good tutorial on checkbox please let me know. Thanks in advance!

View:

@model IEnumerable<sales1.models.userprofile>

       <input type="checkbox" name="RememberMe" id="RememberMe" value="true" />


           @using (Html.BeginForm())
         {
      <input type="submit" value="Save"/>}

控制器：

Controller:

[HttpGet]
  public ViewResult NewOrder()//
  {
      var userprofiles = db.UserProfiles;
      return View(userprofiles);

  }

  public ActionResult NewOrder(bool rememberMe)
  {
      bool remember = Convert.ToBoolean(rememberMe);

      db.SaveChanges();
      return View(remember);

  }

当我运行上面的内容时我得到错误：传入字典的模型项是'System'类型.Boolean'，但是这个字典需要一个'System.Collections.Generic.IEnumerable`1

When I run the above I get the error:The model item passed into the dictionary is of type 'System.Boolean', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1

推荐答案

类型的模型项目如果我理解你的问题，你正在通过来自控制器的对象userprofiles，但它是sholud是列表类型，因为在视图中你收到它IEnumerable类型

所以你可能修改的代码如下：

if i am understanding your question right you are passing a object userprofiles from controller but it sholud be list type because in view you are receiving it IEnumerable type
so your possibly modified code is below :

View: @model IEnumerable

@foreach(var item in Model)//add foreach loop for iteration
[
<input type="checkbox" name="RememberMe" id="RememberMe+'@item'+ " value="true" />
}


@using (Html.BeginForm())
{
<input type="submit" value="Save" />}
 
Controller:
[HttpGet]
public ViewResult NewOrder()//
{
var userprofiles = db.UserProfiles;
return View(userprofiles.TOList());//return a list not a single object

}
 
public ActionResult NewOrder(bool rememberMe)
{
bool remember = Convert.ToBoolean(rememberMe);

db.SaveChanges();
return View(remember);
 
}

我希望这将有助于
