This is my first ASP .Net Core project. It will hold directors. Each director has a page that shows a list of his/her movies.
I have two classes.
Movie:
public class Movie
{
public int MovieId { get; private set; }
public int DirectorId { get; set; }
[Required]
public string Title { get; set; }
public string Year { get; set; }
public string Description { get; set; }
}
And Director:
public class Director
{
public Director()
{
Movies = new List<Movie>();
}
public int DirectorId { get; private set; }
[Required]
public string Name { get; set; }
public string Country { get; set; }
public string Bio { get; set; }
public List<Movie> Movies { get; set; }
}
But I have a problem with editing Directors. As I want to save changes I get this error:
InvalidOperationException: The property 'DirectorId' on entity type
'Director' has a temporary value while attempting to change the
entity's state to 'Modified'. Either set a permanent value explicitly
or ensure that the database is configured to generate values for this
property.
I use this line of code in Index page to navigate to Edit page:
<a asp-page="./../Movies/Create" asp-route-DirectorId="#item.DirectorId">Add Movie</a>
Photo of Index page:
Please click to see the photo
The code in Edit.cshtml.cs:
public class EditModel : PageModel
{
private readonly MastersOfCinema.Data.Context _context;
public EditModel(MastersOfCinema.Data.Context context)
{
_context = context;
}
[BindProperty]
public Director Director { get; set; }
public async Task<IActionResult> OnGetAsync(int? directorId)
{
if (directorId == null)
{
return NotFound();
}
Director = await _context.Director.FirstOrDefaultAsync(m => m.DirectorId == directorId);
if (Director == null)
{
return NotFound();
}
return Page();
}
// To protect from overposting attacks, enable the specific properties you want to bind to, for
// more details, see https://aka.ms/RazorPagesCRUD.
public async Task<IActionResult> OnPostAsync()
{
if (!ModelState.IsValid)
{
return Page();
}
_context.Attach(Director).State = EntityState.Modified;
try
{
await _context.SaveChangesAsync();
}
catch (DbUpdateConcurrencyException)
{
if (!DirectorExists(Director.DirectorId))
{
return NotFound();
}
else
{
throw;
}
}
return RedirectToPage("./Index");
}
private bool DirectorExists(int id)
{
return _context.Director.Any(e => e.DirectorId == id);
}
}
Apparently, Something upsets this very line:
_context.Attach(Director).State = EntityState.Modified;
Perhaps it is about the primary key (DirectorId), As the error suggests.

public class Context : DbContext
{
public Context (DbContextOptions<Context> options)
: base(options)
{
}
public DbSet<MastersOfCinema.Models.Director> Director { get; set; }
public DbSet<MastersOfCinema.Models.Movie> Movie { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseSqlServer(
"Data Source = (localdb)\\MSSQLLocalDB; Initial Catalog = MastersOfCinama");
}
}
Thanks for reading and for any help.
Try removing the private setter from:
public int DirectorId { get; private set; }
Instead it should look like this:
public int DirectorId { get; set; }

I am beginner in ASP.NET Core. I need help with automatically selecting the options of a multi-selection dropdown.
I have a class model and a class can have multiple students. When I am creating the class, I have a dropdown that shows the student list and I can add the students to the class by selecting the options form the drop down.
But I am having issues automatically selecting those values for the edit page. The dropdown should keep those students selected from the list when the edit page loads so that the user can see which students are currently enrolled in the class. I am only seeing the students that are enrolled in the class as option of the dropdown. It should show all the students in the list but select the ones that belongs to the class.
My class model:
public class ClassModel
{
[Key]
[Required]
[Display(Name ="Class ID")]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int ClassID { get; set; }
//[ForeignKey("UserProfile")]
//[Display(Name = "User ID")]
//public virtual int ID { get; set; }
[Required]
public string Description { get; set; }
[Required]
public int Occurence { get; set; }
[Required]

Friends, I'm a beginner and I'm having a hard time getting information from the database of two tables with a one-to-one relationship
I'm currently getting this error:
An unhandled exception occurred while processing the request.
Error
InvalidOperationException: The model item passed into the ViewDataDictionary is of type 'LojaVirtual.Models.person', but this ViewDataDictionary instance requires a model item of type 'LojaVirtual.Models.ViewModels.Student.PersonAddressViewModel'.
I tried to replace it with PersonAddressViewModel, but I get an error stating that it is not a database table. I created it only as an intermediate class. How can I get the data?
I have the "person" and "addresses" table.
below I have the two models for "person" and "address".
person.cs
namespace LojaVirtual.Models
{
public class person
{
public int id_person { get; set; }
public string name { get; set; }
public string email { get; set; }
public string password { get; set; }
public string confirmpassword { get; set; }
[ForeignKey("id_person")]
[JsonIgnore]
public address Address { get; set; }
}
}
address.cs
namespace LojaVirtual.Models
{
public class address
{
[Key]
public int id_address { get; set; }
public string city { get; set; }
public string state { get; set; }
[ForeignKey("person")]
public int? id_person { get; set; }
public virtual person Person { get; set; }
}
}
I created an intermediate class.
PersonAddress.cs
namespace LojaVirtual.Models.ViewModels.Student
{
public class PersonAddressViewModel
{
[Key]
public int id_person { get; set; }
public string name{ get; set; }
public string email { get; set; }
public string password { get; set; }
public string confirmpassword { get; set; }
public string city { get; set; }
public string state{ get; set; }
}
}
The registration is done normally in the two tables, but I have difficulty in bringing the data filled in with the values of the two tables for editing.
This is my editing method:
[HttpGet]
public IActionResult Update()
{
person person = _clientRepository.getperson(_loginPerson.GetClient().id_person);
return View(person);
}
My View
Update.cshtml
#model LojaVirtual.Models.ViewModels.Student.PersonAddressViewModel
#{
ViewData["Title"] = "Update";
}
<h2>Atualizar</h2>
<hr />
<div class="row">
<div class="col-md-4">
<form asp-action="Atualizar">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<input type="hidden" asp-for="id_person" />
<div class="form-group">
<label asp-for="name" class="control-label"></label>
<input asp-for="name" class="form-control" />
<span asp-validation-for="name" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="email" class="control-label"></label>
<input asp-for="email" class="form-control" />
<span asp-validation-for="email" class="text-danger"></span>
.
.

<div class="form-group">
<label asp-for="city" class="control-label"></label>
<input asp-for="city" class="form-control" />
<span asp-validation-for="city" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="state" class="control-label"></label>
<input asp-for="state" class="form-control" />
<span asp-validation-for="state" class="text-danger"></span>
</div>
EDIT
public person getperson(int id_person)
{
return _db.person.Find(id_person);
}
I appreciate if anyone can help.
Any comment is very welcome!
The Update view expect a PersonAddressViewModel type model, so the Update action needs to return a instance of PersonAddressViewModel to it. As #insane_developer metioned, you can use some mapping library, such as Automapper. It’s okay if you haven’t heard that, you can simply map it one by one.
[HttpGet]
public IActionResult Update()
{
person person = _clientRepository.getperson(_loginPerson.GetClient().id_person);
var personAddressViewModel = new PersonAddressViewModel()
{
id_person = person.id_person;
name= person.name;
email = person.email;
password = person.password;
confirmpassword = person.confirmpassword;
city = (person.Address == null) ? null : person.Address.city;
state= (person.Address == null) ? null : person.Address.state
};
return View(personAddressViewModel);
}
How do you bind a checkbox in .net core razor pages?
I'm currently having problems where the checkbox value isn't coming back when I submit the form (using post method).
Below is my code.
domain classes:
public class Restaurant
{
public int Id { get; set; }
[Required, StringLength(80)]
public string Name { get; set; }
public Meals MealsServed { get; set; }
}
public class Meals
{
public int Id { get; set; }
public bool Breakfast { get; set; }
public bool Lunch { get; set; }
public bool Dinner { get; set; }
}
from page model:
[BindProperty]
public Restaurant Restaurant{ get; set; }
public EditModel(IRestaurantData restaurantData, IHtmlHelper htmlHelper)
{
this.restaurantData = restaurantData;
this.htmlHelper = htmlHelper;
}
public IActionResult OnGet(int? restaurantId)
{
Restaurant = restaurantData.GetById(restaurantId.Value);
Restaurant.MealsServed.Breakfast = true;
return Page();
}
public IActionResult OnPost()
{
if (!ModelState.IsValid)
{
return Page();
}
restaurantData.Update(Restaurant);
restaurantData.Commit();
TempData["Message"] = "Restaurant Saved";
return RedirectToPage("./Detail", new { restaurantId = Restaurant.Id });
}
from razor page:
<form method="post">
<input type="hidden" asp-for="Restaurant.Id" />
<div class="form-group">
<label asp-for="Restaurant.Name"></label>
<input asp-for="Restaurant.Name" class="form-control" />
<span class="text-danger" asp-validation-for="Restaurant.Name"></span>
</div>
<div class="form-group">
<input asp-for="Restaurant.MealsServed.Lunch" />
<label asp-for="Restaurant.MealsServed.Lunch"> </label>
</div>
<button type="submit" class="btn btn-primary">Save</button>
</form>
So, I figured out the problem. Everything was correct that I presented above.
After checking the checkbox for Lunch and saving the item, and then viewing the Restaurant item again, it would come back unchecked.
The issue was with the depth of the data that I was pulling from the database. It was only pulling the top level of data.
So, I had to change GetById method from:
public Restaurant GetById(int id)
{
return db.Restaurants.Find(id);
}
to:
public Restaurant GetById(int id)
{
return db.Restaurants.Where(r => r.Id == id).Include(r => r.MealsServed).FirstOrDefault();
}
explicitly telling it to pull the data for the object in the MealsServed property.
I have two models:
public class Question
{
public int Id { get; set; }
public string Title { get; set; }
public int ClosedReasonId { get; set; }
public CloseReasonType CloseReasonType { get; set; }
}
public class CloseReasonType
{
public int Id { get; set; }
public string Name { get; set; }
public List<Question> Questions { get; set; }
}
I would like to create a view which has a form for adding questions and a dropdown for CloseReasonType.
#page
#model RazorPagesQuestion.Pages.Questions.CreateModel
#{
ViewData["Title"] = "Create";
}
<h1>Create</h1>
<h4>Question</h4>
<hr />
<div class="row">
<div class="col-md-4">
<form method="post">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<div class="form-group">
<label asp-for="Question.Title" class="control-label"></label>
<input asp-for="Question.Title" class="form-control" />
<span asp-validation-for="Question.Title" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="Question.CloseReasonType" class="control-label"></label>
<select asp-for="Question.CloseReasonType" class="form-control"
asp-items="Model.CloseReasonType">
</select>
<span asp-validation-for="Question.CloseReasonType" class="text-danger"></span>
</div>
<div class="form-group">
<input type="submit" value="Create" class="btn btn-primary" />
</div>
</form>
</div>
</div>
Of course when I just added asp-items="Model.CloseReasonType" to my select tag helper it didn't populate the dropdown with options. How can I populate the options?
I added this to my CreateModel class
[BindProperty]
public Question Question { get; set; }
[BindProperty]
public List<SelectListItem> CloseReasonType { get; }
All the examples I have seen show how to create the list out of hardcoded values.
The full class:
public class CreateModel : PageModel
{
private readonly RazorPagesQuestion.Data.RazorPagesQuestionContext _context;
public CreateModel(RazorPagesQuestion.Data.RazorPagesQuestionContext context)
{
_context = context;
}
public IActionResult OnGet()
{
return Page();
}
[BindProperty]
public Question Question { get; set; }
[BindProperty]
public List<SelectListItem> CloseReasonType { get; }
public async Task<IActionResult> OnPostAsync()
{
if (!ModelState.IsValid)
{
return Page();
}
_context.Question.Add(Question);
await _context.SaveChangesAsync();
return RedirectToPage("./Index");
}
}
You would need to populate the select list for it to display on the page
Assuming your DbContext has a CloseReasonTypes property
//...
private void loadCloseReasonTypes() {
CloseReasonTypes = new SelectList(_context.CloseReasonTypes, nameof(CloseReasonType.Id), nameof(CloseReasonType.Name));
}
public IActionResult OnGet() {
loadCloseReasonTypes();
return Page();
}
public SelectList CloseReasonTypes { get; set; }
[BindProperty]
public Question Question { get; set; }
//...
Update the view to bind to the relevant property on the model.
<div class="form-group">
<label asp-for="Question.CloseReasonId" class="control-label">Close Reason</label>
<select asp-for="Question.CloseReasonId" class="form-control"
asp-items="Model.CloseReasonTypes">
</select>
<span asp-validation-for="Question.CloseReasonId" class="text-danger"></span>
</div>
The list will also need to be repopulated if the post was not successful as the page will reload, clearing the select list.
public async Task<IActionResult> OnPostAsync() {
if (!ModelState.IsValid) {
loadCloseReasonTypes();
return Page();
}
_context.Question.Add(Question);
await _context.SaveChangesAsync();
return RedirectToPage("./Index");
}
For whatever reason I'm unable to Create and Edit using the ViewModel called CreateEmployeeViewModel that I created. I can however Create and Edit fine without using the CreateEmployeeViewModel but was told it was bad practive to use the main Models for CRUD. I am however able to retrieve values to my 2 DropDownList tags fine using the CreateEmployeeViewModel, just not Create or Edit. Below are my current Models, ViewModels, Controllers and Views.
I just figure out why I cannot Create using the public IActionResult Create(Employee employee) Active Method.

In your Create method, you are sending to the view the CreateEmployeeViewModel but in your HttpPost Create method you are accepting back the Employee model instead of the CreateEmployeeViewModel. So once you change the post methods signature to accept the correct CreateEmployeeViewModel, you can simply map it back to the Employee model.
Get Action Method:
public IActionResult Create(Employee employee)
{
return View(employee);
}
Just change in your Post Action Method:
[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult Create(CreateEmployeeViewModel vm)
{
if (ModelState.IsValid)
{
var model = new Employee{
//your logic here for example
employeename = vm.employeename,
employeepassword = vm.employeepassword
}
_context.Employees.Add(model);
_context.SaveChanges();
return RedirectToAction("Index");
}
return View(employee);
}
and don´t forget to cal View Model in your .cshtml
