Map two entities from one table in ASP.NET

I am working on a library management website. As user of the application, I want to be able to create new employees, for example ceo, manager and regular employee. I have done that and it is working.
But I want to be able to the employees to manage each other depending on their role, for example I want the:
CEO to manage managers but not employees
Managers to manage other managers and employees
No one can manage the CEO
To do that I have tried to map managerID against the id of the employee (I don't know if its a good idea):
public partial class Employees
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)] // For autoincrement
//public int EmployeeId { get; set; }
//[Required]
//[Index]
//public int TheManagerId { get; set; } // Manager ID Foreign Key
//[Required]
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public Nullable<decimal> Salary { get; set; }
public Nullable<bool> IsCEO { get; set; }
public Nullable<bool> IsManager { get; set; }
public Nullable<int> ManagerId { get; set; }
}
And this is how my Create.cshtml looks like:
#model LibraryProject.Employees
#{
ViewBag.Title = "Create";
}
<h2>Create</h2>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Employees</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.FirstName, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.FirstName, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.FirstName, "", new { #class = "text-danger" })

</div>
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.IsManager, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">

</div>
<div class="form-group">

}
<div>

I KNOW IT IS SOME CODE THERE... BUT I HOPE SOMEONE IS OUT THERE TO HELP.
THANKS.

But I want to be able to the employees to manage each other depending on their role, for example I want the:
CEO to manage managers but not employees
Managers to manage other
managers and employees No one can manage the CEO
I think what you want to achieve is Authorize, not the relationship in table.
For how to Customize a Authorize Attribute, You can refer to this thread.

ASP.Net MVC Update entity met with "The entity could not be updated."

I'm fairly new to coding, and am trying to tie up the finishing touches to my personal MVC project. I have done breakpoints to see double-check that the types of the values I'm passing through are matching up, which I believe they are, but it's hard for me to navigate the breakpoints and understand what information I should be looking at.
When I do breakpoints, it skips the final If-statement shown below:
if (service.UpdatePromotion(model))
{
TempData["SaveResult"] = "The promotion has been updated!";
return RedirectToAction("Index");
}
If there is any other information needing to be posted, I'll update here if I can or in the comments. I really appreciate anyone who looks this over.

Shout-out to curious.netter in the comments. I was being lazy with the update, not changing anything and clicking Submit. Since there were no changes to apply, the entity would not update, which would skip the last If statement.

ASP.NET MVC 5 DropDownList from another model

I'm just getting started with MVC. I'm building a project in asp.net mcv 5 using entity framework. I have researched many threads but I didn't find anything that would help solve my problem. I have two models:
Resource:
public class Resource
{
[Key]
public int Id { get; set; }
[Required]
public string Name { get; set; }
public string Comments { get; set; }
[Required]
public ResourceType Type { get; set; }
public bool IsActive { get; set; }
}
ResourceType:
public class ResourceType
{
[Key]
public int Id { get; set; }
[Required]
public string Name { get; set; }
}
And the problem is: In View > Resource > Create I want to add DropDownList for object ResourceType Type with values from class ResourceType string Name

I spent a lot of time looking for a solution to this problem. I would appreciate your feedback on this.

I think the best way to get what you want is to create a ViewModel, this allows you create a view with various classes.
Under your solution create a new folder named ViewModels. Create a new class and name it CreateResourceViewModel.
public class CreateResourceViewModel
{
public Resource Resource {get;set;}
public SelectList ResourceType {get;set;} //this will create the list of resourcetypes
public int IdResourceType {get;set;} //this will be used to select the id of resourceType you are selecting.
public CreateResourceViewModel (Resource resource,List<ResourceType>resourceType) //create a constructor
{
this.Resource = resource;
//here you will set the list as a new selectList, stating where the list will come from. the Id de valuevaluefield, and the name is the valuetextfield
this.ResourceType= new SelectList(resourceType,"Id","Name");
}
public CreateResourceViewModel(){} //you need this second constructor
}
Now you need a Create ActionResult that accepts a ViewModel in your resource Controller
// GET: Locals/Create
public ActionResult Create()
{
Resource resource = new Resource();
List<ResourceType> resourceType;
using (yourcontext db = new yourcontext())
{
resourceType = db.ResourceType.ToList(); //fill your list with the resourceTypes that are in your database
}
CreateResourceViewModel vm = new CreateResourceViewModel(resource,resourceType); //create a new viewmodel and give it the parameters necesary that we created
return View(vm);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(CreateResourceViewModel vm)
{
using (yourcontext db = new yourcontext())
{
if (ModelState.IsValid)
{
try {
vm.Resource.Type = db.ResourceTpe.Find(vm.IdResourceType); //using the ID selected in the view find it in the database
db.Resources.Add(vm.Resource);
db.SaveChanges();
return RedirectToAction("Index");
}
catch (Exception e)
{
e.Message();
}
}
return View(vm);
}
}
Now onto the view for the ViewModel
#model yourSolution.ViewModels.CreateResourceViewModel
#{
ViewBag.Title = "Create";
}
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Resource</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.Name, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Name, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Name, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Comments, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Comments, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Comments, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.ResourceType, htmlAttributes: new { #class = "control-label col-md-2" })
//this is what you need to create a dropdownlist with all the resourceTypes
<div class="col-md-10">
#Html.DropDownListFor(model => model.IdResourceType, Model.ResourceType,"--Select--" )
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.IsActive, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
<div class="checkbox">
#Html.EditorFor(model => model.IsActive)
#Html.ValidationMessageFor(model => model.IsActive, "", new { #class = "text-danger" })
</div>
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Dodaj" class="btn btn-default" />
</div>
</div>
</div>
}
<div>
#Html.ActionLink("Back to list", "Index")
</div>
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
Hope this helps!!

First of you have a mistake to put Resource Controller here (both of Resource and ResourceType are ResourceType). fix it first.
Put in the Here section this code to render a select element from ViewBag.Types:
#Html.DropDownListFor(m => m.Type.Id, (SelectList)ViewBag.Types, new
{
#class = "form-control"
});
Before it you must fill ViewBag.Types in the action, Change the first Create action of ResourceController to this:
[Authorize]
public ActionResult Create()
{
ViewBag.Types = new SelectList(_db.ResourceTypes.ToList(), "Id", "Name", "0");
return View();
}
It will be worked.

ASP.NET MVC multiple models single set of Create, View, Edit and Delete pages

I have a problem figuring out how to implement the Create, Edit and Delete pages for a case where there are multiple Models that I want to display in a single set of Views.
I'm using Visual Studio 2013 and MVC 5. And I also use the latest Entity Framework 6.1.1.
So far I've got the Models:
public class CompositeModel
{
public int ID { get; set; }
public MediaPlan MediaPlanModel { get; set; }
public ContactInfo ContactInfoModel { get; set; }
public MediaPlanDate MediaPlanDateModel { get; set; }
[Timestamp]
public byte[] RowVersion { get; set; }
}
public class MediaPlan
{
public int ID { get; set; }
public string Client { get; set; }
public string Product { get; set; }
public string AE { get; set; }
public string Supervisor { get; set; }
public string Traffic { get; set; }
}
public class ContactInfo
{
public int ID { get; set; }
public string CompanyName { get; set; }
public string CompanyContact { get; set; }
public string CompanyAddress { get; set; }
public string CompanyPhoneNumber { get; set; }
public string CompanyEmail { get; set; }
}
public class MediaPlanDate
{
public int ID { get; set; }
public string Client { get; set; }
public string Product { get; set; }
public string AE { get; set; }
public string Supervisor { get; set; }
public string Traffic { get; set; }
}
Using Code First approach the database was created correctly.
I did auto-generate the CompositeModelsController.cs:
public class CompositeModelsController : Controller
{
private MprContext db = new MprContext();
// GET: CompositeModels
public ActionResult Index()
{
//var compositeModel = new CompositeModel();
//compositeModel.MediaPlanModel = new MediaPlan();
//compositeModel.ContactInfoModel = new ContactInfo();
//compositeModel.MediaPlanDateModel = new MediaPlanDate();
//return View(compositeModel.ToList());
return View(db.Composites.ToList());
}
// GET: CompositeModels/Details/5
public ActionResult Details(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
CompositeModel compositeModel = db.Composites.Find(id);
if (compositeModel == null)
{
return HttpNotFound();
}
return View(compositeModel);
}
// GET: CompositeModels/Create
public ActionResult Create()
{
return View();
}
// POST: CompositeModels/Create
// To protect from overposting attacks, please enable the specific properties you want to bind to, for
// more details see http://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "ID,RowVersion")] CompositeModel compositeModel)
{
if (ModelState.IsValid)
{
db.Composites.Add(compositeModel);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(compositeModel);
}
// GET: CompositeModels/Edit/5
public ActionResult Edit(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
CompositeModel compositeModel = db.Composites.Find(id);
if (compositeModel == null)
{
return HttpNotFound();
}
return View(compositeModel);
}
// POST: CompositeModels/Edit/5
// To protect from overposting attacks, please enable the specific properties you want to bind to, for
// more details see http://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit([Bind(Include = "ID,RowVersion")] CompositeModel compositeModel)
{
if (ModelState.IsValid)
{
db.Entry(compositeModel).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(compositeModel);
}
// GET: CompositeModels/Delete/5
public ActionResult Delete(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
CompositeModel compositeModel = db.Composites.Find(id);
if (compositeModel == null)
{
return HttpNotFound();
}
return View(compositeModel);
}
// POST: CompositeModels/Delete/5
[HttpPost, ActionName("Delete")]
[ValidateAntiForgeryToken]
public ActionResult DeleteConfirmed(int id)
{
CompositeModel compositeModel = db.Composites.Find(id);
db.Composites.Remove(compositeModel);
db.SaveChanges();
return RedirectToAction("Index");
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
db.Dispose();
}
base.Dispose(disposing);
}
}
I did not expect it to work and it doesn't.
I was able to get the Index to work.
I also created Editor Templates:
#model Online_Mpr.Models.MediaPlan
<h2>MediaPlan</h2>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>MediaPlan</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
#Html.HiddenFor(model => model.ID)
<div class="form-group">
#Html.LabelFor(model => model.Client, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Client, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Client, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Product, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Product, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Product, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.AE, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.AE, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.AE, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Supervisor, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Supervisor, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Supervisor, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Traffic, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Traffic, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Traffic, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Save" class="btn btn-default" />
</div>
</div>
</div>
}
<div>
#Html.ActionLink("Back to List", "Index")
</div>
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
And so forth for the other Models.
Then I have the Create View:
#model Online_Mpr.Models.CompositeModel
#{
ViewBag.Title = "Create";
}
<h2>Create</h2>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>CompositeModel</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
#Html.EditorFor(model => model.MediaPlanModel)
#Html.EditorFor(model => model.MediaPlanDateModel)
#Html.EditorFor(model => model.ContactInfoModel)
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</div>
</div>
}
<div>
#Html.ActionLink("Back to List", "Index")
</div>
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
I was planning to do similar thing for the Edit View.
When I go to the Create View it displays the edit boxes for all the elements but how do I get to code the controller that will create the records in the database.
Preferably I would like to have just one "Create" button in the Create View that would create all four records.
Any help is appreciated as I scoured the internet for info about similar cases and could not find any.
Also if you could provide code samples. They don't have to be elaborate but the core thought will lead me on.
Thanks,

Your CompositeModel is essentially a view model. This class shouldn't have an Id property and should n't actually be tied to Entity Framework in any way (don't add a DbSet for it). All it needs to do is contain properties for the other model instances that you want to edit. You should also add a constructor to this class that news up all other models inside:
public class CompositeModel
{
public CompositeModel()
{
MediaPlanModel = new MediaPlan();
ContactInfoModel = new ContactInfo();
MediaPlanDateModel = new MediaPlanDate();
}
...
}
Then in post version of your Create action. You'll simply save each sub-model individually:
[HttpPost]
public ActionResult Create(CompositeModel model)
{
if (ModelState.IsValid)
{
db.MediaPlans.Add(model.MediaPlanModel);
db.ContactInfos.Add(model.ContactInfoModel);
db.MediaPlanDates.Add(model.MediaPlanDateModel)
db.SaveChanges();
return RedirectToAction("Index");
}
return View(model);
}
For your edit version:
[HttpPost]
public ActionResult Edit(CompositeModel model)
{
if (ModelState.IsValid)
{
db.Entry(model.MediaPlanModel).State = EntityState.Modified;
db.Entry(model.ContactInfoModel).State = EntityState.Modified;
db.Entry(model.MediaPlanDateModel).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(model);
}

Drop down initiated when click on enter on validated text box

I've created a MVC5 App which was generated from my model by scaffold the view and controller,
In the model I have a drop down for dev and prod which is working fine, I have validation
for name for alpha-numeric and the problem is for e.g. user chooses prod (the second
option) and enters incorrect data in the name field and presses enter, the view is refreshed and
the drop down changes the selection from prod to dev. How can I avoid that?
How can I ask in the view if the type is different than dev, if so put the selected item?
Model:
public class Ad
{
public int ID { get; set; }
[RegularExpression(#"^[a-zA-Z0-9]*$", ErrorMessage = "Invalid Name")]
public string Name { get; set; }
public IEnumerable<SelectListItem> Type
{
get
{
return new[]
{
new SelectListItem {Value = "D", Text = "Dev"},
new SelectListItem {Value = "p", Text = "Prod"}
};
}
}
View:
<div class="form-group">
#Html.LabelFor(model => model.SystemType, new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownListFor(model => model.Type, Model.Type)
</div>
</div>
Edit the create operation
#model WebApplication3.Models.Ad
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>

$(document).ready(function () {

$('select[name="Type"]').change(function () {
if ($(this).val() === 'p') {
$('input[name="User"]').prop("disabled", true);
$('input[name="Password"]').prop("disabled", true);

On dropdown change event write the selected option value in a hidden field and when page refreshed get the value from hidden field and set the selected item from the action.
$('select#Type').change(function(){
$('#selectedOne').val($(this).val());
});
and in you action read from FormCollection and set selected item of the SelectList
Create Hidden Field in view:
<div class="form-group">
#Html.LabelFor(model => model.SystemType, new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownListFor(model => model.Type, Model.Type)
<input type="hidden" id="selectedOne" vlaue="" name="selectedOne" />
</div>
</div>
In your action:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include="ID,Name,User,Password")] Ad ad,FormCollection form)
{
string selectedValue = form["selectedOne"].ToString();
if (ModelState.IsValid)
{
db.Ad.Add(ad);
db.SaveChanges();
return RedirectToAction("Index");
}
foreach(var item in ad.Type)
{
if(item.Value == selectedValue)
{
item.Selected = true;
}
}
return View(ad);
}
Solution 2:
Another simple solution is to use #Ajax.BeginForm Hepler instead of #Html.BeginForm, so that form posted via ajax, and your dropdown will not get reset.
