why is my foreign key model not validating?

Having started studying asp net core 6, I ran into the problem of invalidity of my model.
What is the hidden problem?

List of fields that participated in validation
From one answer, I realized that the Category field will remain null, and ef core will substitute the values. But I don't quite understand why so many fields are validated without being marked required in the model.

By receives a POST action, ModelState takes all of the name-value pairs and adds them as individual instances of ModelStateEntry to an instance of ModelStateDictionary.
ModelState checks all properties regardless of whether they have a Data annotations or not, such as you get a number, text, file etc. But for those data annotations you put on the properties the ModelState makes a special check based on it.

Just the properties of the model you passed to controller would be validated,you could try custom model validation follow this document:
https://learn.microsoft.com/en-us/aspnet/core/mvc/models/validation?view=aspnetcore-6.0#custom-attributes
And you could try with ModelState.AddModelError(string.Empty, "errormessage");add model level error in backend.

When i try to get data from data for edit page it's showing me error

When I try to get data from data for edit page it's showing me the following error:
So I am building a website where I want to implement a edit banner form when the User can Edit his banner data.
And here is where the problem I raise, when I run the code, it return always as null.
Here is my controller:
[HttpGet]
public ActionResult EditBanner(int id)
{
var abd = (from a in _db.Banner
where id == a.BannerId
select a).FirstOrDefault();
return View(abd);
}
[HttpPost]
public ActionResult UpdateBannerDatas(BannerViewModels bnrupdate)
{
var bnrdata = _db.Banner.Where(x => x.BannerId == bnrupdate.BannerId).FirstOrDefault();
if (bnrdata != null)
{
bnrdata.BannerTitle = bnrupdate.BannerTitle;
bnrdata.BannerUrl = bnrupdate.BannerUrl;
bnrdata.BannerIndex = bnrupdate.BannerIndex;
bnrdata.BannerDescription = bnrupdate.BannerDescription;
bnrdata.BannerIndex = bnrupdate.BannerIndex;
_db.SaveChanges();
}
return Redirect("BannerDetails");
}

When i try To Edit the data in the browser it Throw exception, in database i have value but when i tried to fetch data its showing error.
thank you in advance to everybody for any help or advice.

According to the error message it is necessary to pass the BannerViewModels instance instead of the Banner entity:
public ActionResult EditBanner(int id)
{
var abd = _db.Banner.Where(a => a.BannerId == id)
.Select(b => new BannerViewModels()
{
BannerId = b.BannerId,
BannerTitle = b.BannerTitle,
BannerDescription = b.BannerDescription,
BannerImg = b.BannerImg,
BannerUrl = b.BannerUrl,
BannerIndex = b.BannerIndex,
BMasterId = b.BMasterId,
IsDeleted = b.IsDeleted
})
.FirstOrDefault();
return View(abd);
}
Passing an entity to the view as a data model is bad idea.
See the following post: Why it's not a good idea to pass entities as Models in MVC?

How to reference images from a diferent table C#

I have two tables, Libro (books) and Imagenes (Images) where Id on Libro is referenced on Imagenes as a fk on IdLibro so that I have an image for each Libro.
I want to reference the image on a Bootstrap card but they are on different tables on the database, how do I do it?
Here is what I have
#{
foreach (var lib in Model)
{
<div class="card col-md-3 m-2" style="width: 18rem;">
<img src="#Html.DisplayFor(modelItem => lib.Imagenes)" class="card-img-top" alt="There should be an image here">
<div class="card-body">
<h5 class="card-title">#lib.Titulo</h5>
#switch (lib.Saga)
{
case 0:
<h6> </h6>
break;
case 1:
<h6>Canción de Hielo y Fuego</h6>
break;
case 2:
<h6>Harry Potter</h6>
break;
}
<br />
<div class="row m-2">
<div class="col-md-12">
<p class="card-text">$#lib.Precio</p>
</div>
</div>
<br />
<div class="row m-2 position-absolute bottom-0">
<div class="col-md-4">
<a class="btn btn-outline-primary" href="/Home/Detalle/#lib.Id">Ver</a>
</div>
<div class="col-md-1"></div>
<div class="col-md-4">
<a onclick="Agregar(#lib.Id)" class="btn btn-outline-primary" id="#lib.Id">Agregar</a>
</div>
</div>
</div>
</div>
}
}

If the structure of your classes is as follows, you can easily access the Imagenes class values
public class Libro
{
public int Id { get; set; }
//........................
public ICollection<Imagenes> Imagenes { get; set; }
}
public class Imagenes
{
public int ID { get; set; }
//..............................
public int IdLibro { get; set; }
public Libro Libro { get; set; }
}
in view
#{
foreach (var lib in Model)
{
<img src="Url.Content(lib.Imagenes.FirstOrDefault().ImageUrl)" />
}
}

How to get Model List in Controller

I have this form in MVC Razor . The html is quite long so I am posting the area where I want to work
these are the checkboxes which are populated as service packages
The flow is the user will upload a photo and when proceeds to the next step it goes to a page where he will be selecting service for each photo if he has uploaded 3 photos the three photos will be having the same service
listing but different order IDS
I want is that when a user select services for a specific order means a specific order has multiple services . I want to map it so that Model List will be feteched in the Controller and I can easily insert in the database
this is the HTML:
#using (Html.BeginForm("PlaceOrder", "User", FormMethod.Post, new { id="ServiceForm",#class = "form-horizontal
white-clr", role = "form" }))
{
<!--If user has uploaded a single photo or multiple photo -->
<div class="window-for-choose-service">
#if (ViewBag.OrdersList != null)
{
int i= 1;
foreach (var d in ViewBag.OrdersList)
{
<div class="row">
<div class="col-sm-3 col-md-3 col-lg-3">
<img src="#d.ThumbnailPath" class="img-thumbnail img-responsive" width="250">
</div>
<div class="col-sm-9 col-md-9 col-lg-9">
<form class="white-clr" role="form">
<div class="form-group">
<label for="name">Description</label>
<textarea class="form-control" rows="4"></textarea>
</div>
</form>
</div>
<div class="col-sm-12 col-md-12 col-lg-12">
<div class="panel-group" id="accordion_#d.ID">
<div class="panel panel-primary">
#foreach (var Services in ViewBag.ServicePackages)
{
int cID = Services.ID + d.ID;
//int rndNumber = Convert.ToInt32(TimeSpan.FromSeconds(new Random().Next(0,
11221)).ToString("hmsf"));
if (Services.ServiceParentID == null)
{
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion_#d.ID"
href="#collapseOne_#cID">
#Services.ServiceName
</a>
</h4>
</div>
<div id="collapseOne_#cID" class="panel-collapse collapse in">
<div class="panel-body">
<div>
<div class="table-responsive">
#foreach (var child in Services.ft_service_packages1)
{
//string ness = "ServiceSelected[" + #d.ID + "]";
<div style="width:auto;min-width:250px;float:left; padding:4px; display:inline-block">
<div style="float:left;padding-right:5px;">
<label for="inlinecheckbox_#child.ID">
#Html.CheckBoxFor(m => m.ServiceSelect, new { id = "inlinecheckbox_" +
#child.ID, price_attr = "#child.ServicePrice"})
#Html.HiddenFor(m => m.UploadOrderID, new { Value = #d.ID })
</label>
</div>
<div style="padding-left:2px;">#child.ServiceName</div>
</div>
}
</div>
</div>
</div>
</div>
i++;
}
}
</div>
</div>
</div>
<div class="col-sm-12 col-md-12 col-lg-12"><p class="text-right font-blue"><b> Price $
0.0</b></p> </div>
</div>
}
}
The Html is genereting perfectly fine . But the thing is not getting anything in the controller regarding the model
Model is listed below
using System;
using System.Collections.Generic;
public partial class ft_order_itemized
{
public int ID { get; set; }
public int UploadOrderID { get; set; }
public int ServiceSelected { get; set; }
public decimal ServiceCharges { get; set; }
public System.DateTime ServiceSelectedDate { get; set; }
public Nullable<int> OrderID { get; set; }
public bool ServiceSelect { get; set; }
public virtual ft_orders ft_orders { get; set; }
public virtual ft_service_packages ft_service_packages { get; set; }
public virtual ft_uploads_orders ft_uploads_orders { get; set; }
}
My Controller :
[HttpPost]
public ActionResult PlaceOrder(ICollection<ft_order_itemized> Orders)
{
if (Orders.Count > 0)
{
}
// ICollection Allstrings = Orders["Service"].ToList();
return View();
}

As the error message indicates, you are passing a class of type OrgProje to a view that requires a view of type ProjeEkleDto.
Your error occurs in this action method:
[HttpPost]
public ActionResult ProjeEkle(OrgProje model)
{
try
{
svc.ProjeEkle(model);
return RedirectToAction("Index", "Home");
}
catch(Exception ex)
{
}
return View(model); // Passing a view model of the wrong type to the view
}
Either pass a view model of type ProjeEkleDto back to the view instead of your model of type OrgProje, or create a different view that accepts a view model of type OrgProje.

In your view Change -
#model LibOrganizerSvc.Dto.ProjeEkleDto
to
#model NameSpace.ProjeEkleDto
I am not sure about which namespace to be used, but you replace NameSpace with appropriate one.
