在MVC中对集合进行分组查看并在控制器中更新模型？
|
我有一个View，它显示一个ViewModel的集合，用户可以在其中更新每个集合项的属性（熟练程度的\“ Level \”）。
这是视图：
@model Consultants.ViewModels.ProgramsViewModel
@{
ViewBag.Title = \"Programkunskaper\";
}
<h2>@ViewBag.Title</h2>
<div id=\"formDiv\">
@using (Html.BeginForm(null, null, FormMethod.Post, new { id = \"myForm\" }))
{
@Html.ValidationSummary(true)
<fieldset>
<legend>Ny arbetserfarenhet</legend>
<table>
<tr>
<th>
Program
</th>
<th>
Nivå
</th>
</tr>
@Html.EditorFor(m => m.ProgramSkills, \"ProgramSkills\")
@*Using editorformodel instead of for loop according to tip here: http://stackoverflow.com/questions/5420471/use-dropdownlistfor-with-foreach-in-asp-net-mvc-view*@
</table>
<p>
<input type=\"submit\" value=\"Spara\" />
</p>
</fieldset>
}
</div>
@model Consultants.Models.ProgramSkill
<tr>
<td>@Model.Program.Name
</td>
<td>
@Html.DropDownListFor(
model => model.Level,
new SelectList(new[] { 0, 1, 2, 3, 4, 5 },
Model.Level
)
)
</td>
</tr>
public ActionResult Index()
{
Consultant consultant = _repository.GetConsultantByUserName(User.Identity.Name);
ViewBag.Consultant = consultant;
if (consultant.ProgramSkills.Count == 0)
{
List<Program> programs = _repository.GetAllPrograms();
foreach (var program in programs)
{
consultant.ProgramSkills.Add(new ProgramSkill { Program = program });
}
_repository.Save();
}
ProgramsViewModel vm = new ProgramsViewModel();
vm.ProgramSkills = consultant.ProgramSkills.ToList();
return View(vm);
}
[HttpPost]
public ActionResult Index(ProgramsViewModel vm, FormCollection collection)
{
Consultant consultant = _repository.GetConsultantByUserName(User.Identity.Name);
List<ProgramSkill> programSkills = consultant.ProgramSkills.ToList();
for (int i = 0; i < programSkills.Count; i++)
{
var programSkill = programSkills[i];
programSkill.Level = vm.ProgramSkills[i].Level;
}
_repository.Save();
vm.ProgramSkills = programSkills;
return View(vm);
}

ProgramSkillsModel { string Category {get;set;} IList<ProgramSkill> Skills {get;set;} }ProgramsViewModel vm = new ProgramsViewModel(); vm.ProgramSkills = consultant.ProgramSkills.GroupBy(c => c.Category) .Select(c => new ProgramSkillsModel{ Category = c.Key, Skills = c.ToList(), });
