How can I get data from Class.cs and show in drop-down with proper validation of drop-down on button click.
If everything is OK, then store data in Subject.cs with Class Id value.

I am using Auto mapper to map between modelviews and models. I have followed the same steps given by the Auto mapper documentation and still can't find where the issue is.

I am developing a shop application and I need to show products of each category. The problem is each product is created from a product template which is stored in a table and each template is related to a category. here is the product model:
namespace fardashahr.Models
{
[Table("Product")]
public class ProductModel
{
public ProductModel()
{
if (Specs == null)
{
Specs = new Dictionary<string, SpecItemsModel>();
}
}
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
[Required]
public int ProductTemplateId { get; set; }
[Required]
public bool IsPublished { get; set; }
[Required]
public bool InStock { get; set; }
[Range(95, 110)]
public float SyncRate { get; set; }
public DateTime? ProductionDate { get; set; }
[Required]
public DateTime RegisterationDate { get; set; }
public string ImageName { get; set; }
public IEnumerable<string> GalleryImages { get; set; }
[NotMapped]
public Dictionary<string, SpecItemsModel> Specs { get; set; }
[ForeignKey("ProductTemplateId")]
public virtual ProductTemplateModel ProductTemplate { get; set; }
[ForeignKey("ManufacturerId")]
public virtual CodingItemModel Manufacturer { get; set; }
[ForeignKey("BrandId")]
public virtual CodingItemModel Brand { get; set; }
[ForeignKey("ModelId")]
public virtual CodingItemModel Model { get; set; }
[ForeignKey("SeriesId")]
public virtual CodingItemModel Series { get; set; }
}
}
and here is the the ProductTemplate:
namespace fardashahr.Models
{
[Table("ProductTemplate")]
public class ProductTemplateModel
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
[StringLength(500)]
public string Name { get; set; }
[Required]
public int CategoryId { get; set; }
[StringLength(500)]
public string Description { get; set; }
[ForeignKey("CategoryId")]
public virtual CategoryModel Category{ get; set; }
}
}
and the controller is:
namespace fardashahr.Controllers
{
public class ProductsController : Controller
{
// GET: Products
public ActionResult Index()
{
return RedirectToAction("Index", "Home");
}
public ActionResult Category(string name)
{
//declare a list of products
List<ProductModel> productList;
using(MainModel db = new MainModel())
{
//get category id
CategoryModel category = db.Categories.Where(x => x.CategorytUrl == name).FirstOrDefault();
int catId = category.Id;
//initialize the list
productList = db.Products.Where(x => x. == catId).ToList();
}
}
}
}
finaly, what I want to know is how to initialize a list of products.
In your models, you added virtual keyword which indicates that navigation property will be automatically loaded without the need of LINQ lambda .include() expression.
Hence you can immediately access the navigation property and load the list like this;
productList = db.Products.Where(x => x.ProductTemplate.CategoryId == catId).ToList();
string categoryNameOfFirstProduct = productList.FirstOrDefault().ProductTemplate.Category.Name;
string categoryNameOfFirstProduct = productList.FirstOrDefault().ProductTemplate.Category.CategorytUrl;

I have a complex model named CreateProjeModel. I'm using 'for' to loop collection properties and binding like below:
#Html.TextBoxFor(m => m.GeometryList[i].PointList[j].X)
Action is like below:
[HttpPost]
public async Task<ActionResult> Create(CreateProjeModel proje)
{
//ToDo
return View(proje);
}
Posted data is below:
When it comes to action, GeometryList is empty and Proje's properties are not set to post values. Where am I doing wrong?
Your problem is that your CreateProjeModel model has a property named Proje, but the parameter of your Create() method is also named proje. Your need to change the method signature to (say)
public async Task<ActionResult> Create(CreateProjeModel model)
where the parameter name is not the same as the nae of one of your properties
I have different models Image,Page & PageCategories
public class Image
{
public int ImageId { get; set; }
public string ImageTitle { get; set; }
public string ImageURL { get; set; }
}
public class Page
{
public int PageId { get; set; }
public string PageTitle { get; set; }
public string Content { get; set; }
public int PageCategoryId { get; set; }
public virtual PageCategory PageCategory { get; set; }
}
public class PageCategory
{
public int PageCategoryId { get; set; }
public string CategoryName { get; set;
public virtual ICollection<Page> Pages { get; set; }
}
DBContext Class is
class DemoContext:DbContext
{
public DbSet<PageCategory> PageCategories { get; set; }
public DbSet<Page> Pages { get; set; }
public DbSet<Image> Images { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}
}
I am wondering how to get all the model data to the home page using ViewModel.
For Ex.:
How to get image list and Page list in home page from multiple models?
You may want something like this :
viewModel :
//Create a viewModel with all the properties that you need
public class ViewModel
{
public int ImageId { get; set; }
public string ImageTitle { get; set; }
public string ImageURL { get; set; }
public int PageId { get; set; }
public string PageTitle { get; set; }
public string Content { get; set; }
public int PageCategoryId { get; set; }
public string CategoryName { get; set; }
}
Controller :
...
using (DemoContext db = new DemoContext()){
List<ImagePageViewModel> viewData = (from p in db.Page
join pc from db.PageCategory on p.PageCategoryId equals pc.PageCategoryId
select new ViewModel(){
PageTitle=p.PageTitle,
CategoryName = pc.CategoryName
//... set every property you want
})
}
return View(viewData );
note: I didn't add Image to the query because there is no explicit relation
between Image and the others table so i let you do it.
Create another class and define all above three into it. like below
public class MyView
{
public List<Image> Images { get; set; }
public List<Page> Pages { get; set; }
public List<PageCategory> PageCategories { get; set; }
}
Controller Action:-
public ActionResult Index()
{
MyView myView = // Get it using your logic
return View(myView);
}
finally got my answer:
public class ViewModelDemo
{
public IEnumerable<Image> images { get; set; }
public IEnumerable<Pages> pages { get; set; }
public IEnumerable<PageCategory> pagecategories { get; set; }
}
Then in HomeController
private DemoContext db=new DemoContext();
public ActionResult Index()
{
ViewModelDemo vm = new ViewModelDemo();
vm.images = db.Images.ToList();
vm.pages=db.Pagess.ToList();
vm.pagecategories=db.PageCategories.ToList();
return View(vm);
}
