[英]When updating partial View the forms content is cleaned
我正在制作一个表格,用于记录用户的个人数据和工作经历。 MVC5。
我有一个包含Clients和JobExperiences实体的模型,首先使用EF代码创建
在这个模型上,我像这样创建了视图模型。
工作经验的视图模型
public class JobExperienceViewModel
{
[Required]
[Display(Name = "Nombre Compañia")]
public string CompanyName { get; set; }
[Required]
[Display(Name = "Fecha de Ingreso")]
[DataType(DataType.Date)]
public DateTime EntryDate { get; set; }
[Required]
[Display(Name = "Fecha de Retiro")]
[DataType(DataType.Date)]
public DateTime RetirementDate { get; set; }
[Required]
[Display(Name = "Cargo")]
public string Role { get; set; }
[Required]
[Display(Name = "Funciones")]
public string Functions { get; set; }
[Required]
[Display(Name = "Motivo de Retiro")]
public string RetirementCause { get; set; }
}
用于保存个人数据和工作经历的Resume视图模型,例如公共类ResumeViewModel {
public ResumeViewModel(Client client, ApplicationUser user)
{
...
}
public List<JobExperienceViewModel> JobExperienceViewModels { get; set; }
[Display(Name = "Primer nombre")]
public string FirstName { get; set; }
[Display(Name = "Segundo nombre")]
public string MiddleName { get; set; }
[Display(Name = "Primer apellido")]
public string LastName { get; set; }
}
我创建了一个Resume Controller来处理所有这些数据
public class ResumeController : Controller
{
#region Global Actions
//
// GET: /Resume/
//This method loads the information for a given userName and loads the viewmodel and pass it to the view
[Authorize(Roles = "Admin, Recepcionista, Orientador")]
public ActionResult Index(string userName)
{
var context = new ApplicationDbContext();
var user = (from _user in context.Users
where _user.UserName == userName
select _user).FirstOrDefault();
Client client = new Client();
try
{
client = (from _client in context.Client
where _client.ApplicationUserId == user.Id
select _client).FirstOrDefault();
}
catch (System.Reflection.TargetException)
{
client = new Client();
}
ResumeViewModel model;
model = new ResumeViewModel(client, user);
TempData["ResumeViewModel"] = model;
return View(model);
}
//This method is inttended to save all resume data to persistence
[HttpPost]
public ActionResult Index(ResumeViewModel model)
{
ApplicationDbContext context = new ApplicationDbContext();
bool exists = false;
var client = (from _client in context.Client
where _client.ApplicationUserId == model.ApplicationUserId
select _client).FirstOrDefault();
if (!String.IsNullOrEmpty(client.ApplicationUserId))
{
exists = true;
}
client.Address = model.Address;
client.ArmyCard = model.ArmyCard;
client.ArmyCardClass = model.ArmyCardClass;
client.BasicKnowledgeCoreId = model.SelectedBasicKnowledgeCoreId;
client.BirthCityId = model.SelectedBirthCityId;
client.BirthCountryId = model.SelectedBirthCountryId;
client.BirthDate = model.BirthDate;
client.BirthDepartmentId = model.SelectedBirthDepartmentId;
client.CellPhoneNumber = model.CellPhoneNumber;
client.Comments = model.Comments;
client.DataVisibilityLevelId = model.SelectedDataVisibilityLevelId;
client.DocumentNumber = model.DocumentNumber;
client.DocumentTypeId = model.SelectedDocumentTypeId;
client.DrivingLicenceExpirationDate = model.DrivingLicenceExpirationDate;
client.DrivingLicenseCategoryId = model.SelectedDrivingLicenseCategoryId;
client.EducationCountryId = model.SelectedEducationCountryId;
client.FirstNationalityId = model.SelectedFirstNationalityId;
client.GenreID = model.SelectedGenreId;
client.GraduationYear = model.GraduationYear;
client.HandicapTypeID = model.SelectedHandicapTypeID;
client.HasWorkExperience = model.HasWorkExperience;
client.HireTypeId = model.SelectedHireTypeId;
client.HomeCityId = model.SelectedHomeCityId;
client.HomeCountryId = model.SelectedHomeCountryId;
client.HomeDepartmentId = model.SelectedHomeDepartmentId;
client.Institution = model.Institution;
client.IsGraduated = model.IsGraduated;
client.IsHomeOfficeInterested = model.IsHomeOfficeInterested;
client.IsHouseHoldHead = model.IsHouseHoldHead;
client.LanguageId = model.SelectedLanguageId;
client.LanguageSkillLevelID = model.SelectedLanguageSkillLevelID;
client.MarriageStatusId = model.SelectedMarriageStatusId;
client.Neighborhood = model.Neighborhood;
client.PhoneNumber = model.PhoneNumber;
client.ProCardExpeditionDate = model.ProCardExpeditionDate;
client.ProCardNumber = model.ProCardNumber;
client.ProfessionalCardCareer = model.ProfessionalCardCareer;
client.ProfessionalProfile = model.ProfessionalProfile;
client.SalaryRangeId = model.SelectedSalaryRangeId;
//Este campo está comentadoporque el proceso de registro debe hacerse por detalles del nivel, donde esta elid y sus detalles.
//client.ScholarLevelId = model.SelectedScholarLevelId;
client.SecondNationalityId = model.SelectedSecondNationalityId;
client.Title = model.Title;
client.WorkStatusID = model.SelectedWorkStatusID;
if (!exists)
{ context.Client.Add(client); }
try
{
if (context.SaveChanges() > 0)
RedirectToAction("Index", "SearchClient");
else { return View(model); }
}
catch (Exception)
{
return View(model);
throw;
}
return View(model);
}
#endregion
#region JobExperience
public ActionResult ShowJobExperience(ICollection<Models.JobExperienceViewModel> JobExperienceViewModels)
{
return View(JobExperienceViewModels);
}
public ActionResult CreateJobExperience(ICollection<Models.JobExperienceViewModel> JobExperienceViewModels)
{
return View(JobExperienceViewModels);
}
[HttpGet]
public ActionResult CreateJobExperience(Models.JobExperienceViewModel JobExperienceViewModel)
{
#region Using TempData
ResumeViewModel model = (ResumeViewModel)TempData["ResumeViewModel"];
model.JobExperienceViewModels.Add(JobExperienceViewModel);
TempData["ResumeViewModel"] = model;
#endregion
return View("Index", model);
}
#endregion
}
最后,意见以这种方式组织。 父视图包含所有个人数据,并且jobExperiences列出并创建视图作为大表单内的部分视图。
该观点的相关部分是
@model CAEWebSite.Models.ResumeViewModel
@{
ViewBag.Title = "Hoja de Vida";
}
@using (Ajax.BeginForm(null))

问题
每当我创建新的工作经验时,我都会更新viemodel,将jobExperienceViewModel添加到经验列表中,然后将其发送回视图以返回。
它的工作原理是,经验列表似乎已满。 但是,表格中的所有数据都丢失,清除了。
我正在使用在所有用户交互过程中保持viewmodel状态的方法,直到当我将所有模型发送给持久性时他或她单击提交的表单。
我认为我需要的是一种更新体验列表的方式,就像在老式的Updatepanel中一样。
或使我无法使用该功能的解决方法。
在这里,您将使用Ajax表单提交劳动经验,而不用“主要形式”清除数据:
模型:
public class HojaDeVida
{
public HojaDeVida()
{
ExperienciasLaborales = new List<ExperienciaLaboral>();
}
public string Nombre { get; set; }
public string Apellido { get; set; }
public IList<ExperienciaLaboral> ExperienciasLaborales { get; set; }
}
public class ExperienciaLaboral
{
public string Empresa { get; set; }
public int Anios { get; set; }
}
控制器:
public class HomeController : Controller
{
[HttpGet]
public ActionResult Index()
{
TempData["hojavida"] = new HojaDeVida();
return View();
}
[HttpPost]
public ActionResult Index(HojaDeVida hojaDeVida)
{
//Submit the info in "hojaDeVida" and TempData["HojaVida"]
return new EmptyResult();
}
[HttpPost]
public PartialViewResult AddExperienciaLaboral(ExperienciaLaboral experiencia)
{
var hojadevida = (HojaDeVida)TempData["hojavida"];
hojadevida.ExperienciasLaborales.Add(experiencia);
TempData["hojavida"] = hojadevida;
return PartialView("_ListExperiencias", hojadevida.ExperienciasLaborales);
}
}
“主要视图”(Hoja de Vida):
@using WebApplication1.Controllers
@model HojaDeVida
@{
ViewBag.Title = "Home Page";
}
@using (Html.BeginForm("Index", "Home"))
{
<div>
@Html.LabelFor(x => x.Nombre)
@Html.EditorFor(x => x.Nombre)
</div>
<div>
@Html.LabelFor(x => x.Apellido)
@Html.EditorFor(x => x.Apellido)
</div>
<input type="submit" value="Guardar Hoja de Vida" />
}
@Html.Partial("_AddExperiencia", new ExperienciaLaboral())
@section scripts
{
@Scripts.Render("~/Scripts/jquery.unobtrusive-ajax.min.js")
}
然后使用Ajax形式的“ _AddExperience” PartialView:
@using WebApplication1.Controllers
@model ExperienciaLaboral
@using (Ajax.BeginForm("AddExperienciaLaboral", "Home", new AjaxOptions { UpdateTargetId = "data", HttpMethod = "POST" }))
{
<div>
@Html.LabelFor(x => Model.Empresa)
@Html.EditorFor(x => Model.Empresa)
</div>
<div>
@Html.LabelFor(x => Model.Anios)
@Html.EditorFor(x => Model.Anios)
</div>
<input type="submit" value="Agregar Experiencia" />
}
<div id="data">
@Html.Partial("_ListExperiencias", new List<ExperienciaLaboral>())
</div>
最后是“ _ListExperiencias” PartialView:
@model IList<WebApplication1.Controllers.ExperienciaLaboral>
@foreach (var item in Model)
{
<div>
@string.Format("Empresa : {0} | Años: {1}", item.Empresa, item.Anios)
</div>
}
如您所见,Ajax表单位于HTML表单之外, 您不能嵌套两个表单 (此处为Ajax表单和HTML表单),而是需要使用某些JavaScript或jQuery.Ajax来嵌套漂亮的可视表单
您可以使用Ajax + Web API或控制器中的任何操作来保存体验。
