我该如何做...查看MVC 5上的多个模型 [英] How Can I do this ...Multiples models on view MVC 5

问题描述

我要执行此视图..我有一个模型调用Product Options，我需要在视图中显示不同表的名称或照片路径

I want to do this view .. I have a model call Product Options and I need to bring on the view the name or photo path for different tables

   public class ProductOption
    {
        public int id { get; set; }
        [Display(Name = "Product")]
        public int ProductId { get; set; }
        [Display(Name = "Group")]
        public int GroupId { get; set; }
        [Display(Name = "Option")]
        public int OptionId { get; set; }
        [Display(Name = "Price")]
        public decimal priceIncrement { get; set; }

     } 
    }

这是产品型号:

 public class Product
    {
        public int Id { get; set; }
        [Display(Name = "Product Name")]
        public string Name { get; set; }
        [Display(Name = "Category")]
        public int CategoryId { get; set; }
        [Column(TypeName = "Money")]
        public decimal Price { get; set; }
        [Display(Name = "Image")]
        public string PhotoPath { get; set; }
        [Display(Name = "Discount")]
        public int DiscountId { get; set; }
        [Display(Name = "Enable")]
        public bool status { get; set; }
        public virtual ICollection<ProductOption> ProductOptions { get; set; }
    }

OptionsGroup模型

OptionsGroup Model

public class OptionsGroup
    {
        public int OptionsGroupId { get; set; }
        [Display(Name = "Group Name")]
        public string OptionsGroupName { get; set; }
        public virtual ICollection<Option> Options { get; set; }
    }

选项模型

public class Option
    {
        public int OptionId { get; set; }
        [Display(Name="Option Name ")]
        public string OptionName { get; set; }
        [Display(Name = "Group Name ")]
        public int OptionsGroupId { get; set; }
        public virtual OptionsGroup OptionsGroup { get; set; }
    }

推荐答案

据我了解，您希望可以在一个视图中访问三个不同的模型.这可以通过多种方式.

From what I understand, you want to have access to three different Models within a single View. This is possible via a number of different ways.

我一直创建一个 ViewModel ，其中包含我在视图中所需的每个模型的对象.例如，如果您需要三个模型:Product，Option和OptionsGroup，我将这样创建一个ViewModel:

I've always created a ViewModel that contains objects of each individual Model I require in my view. For example, If you require three models: Product, Option and OptionsGroup, I would create a ViewModel as so:

public class ProductOptionsVM
{
    public Product product { get; set; }
    public Option options { get; set; }
    public OptionsGroup optiongroup { get; set; }
}

当您希望访问任何ProductOptionsVM对象时，必须记住使用访问器(就像使用常规Model一样)来操纵Model对象的每个属性，如下所示:

When you wish to access any ProductOptionsVM objects, you must remember to use the accessors (as you would a regular Model) to manipulate the each property of Model object like so:

public ViewResult setProductDetails(ProductOptionsVM poViewModel)
{
    poViewModel.product.Id = 1;
    poViewModel.product.Name = "MyProductName";
    poViewModel.product.CategoryId = 1;
    poViewModel.product.Price = 123.45m;
    poViewModel.product.PhotoPath = "C:\Users\Marimar\Desktop\images\myimage.jpg"
    poViewModel.product.DiscountId = 1;
    poViewModel.product.Status = false;
    poViewModel.product.ProductOptions = _productService.GetAllProductOptions();

    return View(obj); /* Your product model will be initialized,
                         whilst the Options and OptionGroup model is null */
}

注意:作为一种好的做法，创建任何ViewModel时，后缀应为VM或ViewModel.

Note: As a good practice when you create any ViewModel, it should have a suffix as VM or ViewModel.
