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 class="form-group">

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

#Html.ValidationMessageFor(model => model.IsCEO, "", 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 class="checkbox">
#Html.EditorFor(model => model.IsManager)
#Html.ValidationMessageFor(model => model.IsManager, "", new { #class = "text-danger" })
</div>
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.ManagerId, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.ManagerId, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.ManagerId, "", new { #class = "text-danger" })
</div>
</div>
<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")
}
#using (Html.BeginForm())
{
if (!string.IsNullOrEmpty(ViewBag.ErrorMessage5))
{
<div>
<p>
<span style="color:red;">#ViewBag.ErrorMessage5</span>
</p>
</div>
}
<div class="form-horizontal" />
}

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.

Validation Message doesn't show for model as property in viewmodel

i've been struggling with Model validation message in asp.net
I've got a model used by a viewmodel.
I want my view to display validation errors if users don't fill required fields.
My ModelState.IsValid is false when required fields are not fill (expected behaviour) but i can't see

Thanks.

I believe that you should return View when the ModelState is invalid.
Return View doesn't make a new requests, it just renders the view
without changing URLs in the browser's address bar.
Return RedirectToAction makes a new request and the URL in the browser's
address bar is updated with the generated URL by MVC.
try
{
if (ModelState.IsValid)
{
bool result = *DatabaseStuff*
if(result == true)
{
return RedirectToAction("Index");
}
else
{
return View();
}
}
return View();
}

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.

MVC Dropdown list from a froma different Model

I'm trying to create a dropdown on my View that populates all the usernames specified in a different table.
I've tried the tuple route but it doesn't seem to be working for me.
Also looked into adding a model containing both models (Users and Tasks)
View
#model Tuple<Task,User>
#{
ViewBag.Title = "Create";
}
<h2>Create</h2>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Task</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.Item1.Name, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Item1.Name, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Item1.Name, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Item1.Details, htmlAttributes: new { #class = "control-label col-md-2" })

How to send dropdown value from view to controller

I have the following create view
#model Inspinia_MVC5.Areas.GlobalAdmin.Models.Propiedad

}
protected override void Dispose(bool disposing)
{
if (disposing)
{
db.Dispose();
}
base.Dispose(disposing);
}
}
However when I created a row, the database shows the foreign KEY as null (Entidad ID)
What am I missing here?
Propiedad Model is this
public class Propiedad
{
[Key]
public int Id { get; set; }
public virtual Entidad Entidad { get; set; }
public string Codigo { get; set; }
public string Nombre { get; set; }
public string TipoDeDatos { get; set; }
}
Screenshot
http://screencast.com/t/B5m6X8mtbSdd
Update 1: I modified the controller like this:
public ActionResult Create()
{
ViewBag.Entidad = new SelectList(db.Entidades, "Id", "Nombre");
return View();
}
and the view like this:
<div class="form-group">
#Html.LabelFor(model => model.Entidad, new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownListFor(model => model.Entidad.Id, new SelectList(ViewBag.Entidad, "Id", "Nombre", Model.Entidad.Id), "Seleccionar", new { #class = "form-control" })
</div>
</div>
However on the view I get an object reference not set to an instance of an object.
This is the entity model
public class Entidad
{
[Key]
public int Id { get; set; }
public string Nombre { get; set; }
public virtual ICollection<Propiedad> Propiedades { get; set; }
}
and the property model
public class Propiedad
{
[Key]
public int Id { get; set; }
public virtual Entidad Entidad { get; set; }
public string Codigo { get; set; }
public string Nombre { get; set; }
public string TipoDeDatos { get; set; }
}

I don't see where print the dropdownlist in your view.
Well try this:
In your controller load the list:
ViewBag.entities = new SelectList(db.Entidades, "Id", "Nombre") ;
And then in your view inside the form:
#Html.DropDownListFor(model => model.Entidad.Id, (SelectList) ViewBag.entities, "Seleccionar")
Model equivalent a your class: Propiedad
With this you will automatically receive the object with the selected value.
