Asp.Net店產品屬性（尺寸，數量）

Question

我有作爲this question

我有一個產品表列

(PK)Product_Id, (FK)Category_Id, Name, Description, Size, Color, Quantity, Price, Condition 

現在我存儲這些同樣的問題通過簡單的形式與所有字段的值。

型號 Product.cs

public partial class Product 
{ 
    [Key] 
    public int ProductId { get; set; } 

    [Required] 
    [StringLength(50)] 
    public string Name { get; set; } 

    [AllowHtml] 
    public string Description { get; set; } 

    public decimal? Price { get; set; } 

    public int? Quantity { get; set; } 

    public string Condition { get; set; } 

    [StringLength(50)] 
    public string Size { get; set; } 

    [StringLength(50)] 
    public string Colors { get; set; } 
} 

查看大小和顏色是由簡單的複選框存儲。

@using (Html.BeginForm("AddProduct", "Store", FormMethod.Post, new { enctype = "multipart/form-data", @class = "form-horizontal", role = "form" })) 
{ 
@Html.AntiForgeryToken() 
<h4>Create a new product.</h4> 
<hr /> 
@Html.ValidationSummary(true) 
<div class="form-group"> 
    @Html.LabelFor(m => m.Name, new { @class = "col-md-2 control-label", data_val_required = "required" }) 
    <div class="col-md-10"> 
     @Html.TextBoxFor(m => m.Name, new { @class = "form-control" })

     <input type="submit" class="btn btn-default" value="Create Product" /> 
    </div> 
</div> 
} 

控制器

存儲所述產品使用此代碼

[HttpPost] 
public ActionResult AddProduct(Product newRecord) 
    { 
        newRecord.Name = Request.Form["Name"]; 
        newRecord.CategoryId = Convert.ToInt32(Request.Form["CategoryId"]); 
        newRecord.Size = Request.Form["Size"]; 
        newRecord.Colors = Request.Form["Color"]; 
        newRecord.Description = Request.Unvalidated.Form["Description"]; 
        newRecord.Price = Convert.ToDecimal(Request.Form["Price"]); 
        newRecord.Quantity = Convert.ToInt32(Request.Form["Quantity"]); 
        db.Products.Add(newRecord); 
        db.SaveChanges(); 
        return RedirectToAction("Index", "Home"); 
    } 

並且該值被存儲在1行。我如何用尺寸存儲尺寸？作爲引用的問題。

請檢查this鏈接以更好地瞭解此問題，當您在尺寸上移動鼠標時，它會顯示庫存中的左側物品。我想實現這一點。

您的數據庫和模型設計對於您想要實現的目標不正確。您需要一個表格（例如Product），其中包含ID，名稱，說明和價格（假設價格不隨尺寸變化）等常見屬性，另一個表格（如`ProductStock）爲Size和StockQuantity用產品表中的FK）。你爲什麼要使用`的Request.Form [..]`得到的值時，你已經

你的車型會是這樣的

public class Product 
{ 
    public int ID { get; set; } 
    public string Name { get; set; } 
    public string Description { get; set; } 
    public decimal Price { get; set; } 
    public List<ProductStock> Stock { get; set; } 
} 
public class ProductStock 
{ 
    public int ID { get; set; } 
    public string Size { get; set; } // and enum may be better if the possible values wont change 
    public int Quantity { get; set; } 
} 

那麼你的看法是什麼樣

@model Product 
<h2>@Html.DisplayFor(m => m.Name</h2> 
@Html.DisplayFor(m => m.Description) 
@Html.DisplayFor(m => m.Description) 
@foreach(var item in Stock) 
{ 
    @Html.DisplayFor(m => item.Size) 
    @Html.DisplayFor(m => item.Quantity) 
}
