[转]教你一招 - 如何给nopcommerce增加新闻类别模块
本文转自：http://www.nopchina.net/post/nopchina-teach-newscategory.html
nopcommerce的新闻模块一直都没有新闻类别，但是很多情况下都会使用到类别，怎么办呢，自己动手吧。
1、首先创建新闻类别表，脚本如下：
|
1
2
3
4
5

CREATE TABLE [dbo].[NewsCategory]( [Id] [int] IDENTITY(1,1) NOT NULL, [Name] [nvarchar](400) NOT NULL, [Description] [nvarchar](max) NOT NULL, [ParentCategoryId] [int] NOT NULL, [Published] [bit] NOT NULL, [Deleted] [bit] NOT NULL, [DisplayOrder] [int] NOT NULL, [CreatedOn] [datetime] NOT NULL, [UpdatedOn] [datetime] NOT NULL, CONSTRAINT [PK_NewsCategory] PRIMARY KEY CLUSTERED ( [Id] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]GO |
2、\Libraries\Nop.Core\Domain\News下面增加实体类，代码如下：

using System;using System.Collections.Generic;using Nop.Core.Domain.Localization;namespace Nop.Core.Domain.News{ /// <summary> /// Represents a news category /// </summary> public partial class NewsCategory : BaseEntity { /// <summary> /// Gets or sets the name /// </summary> public virtual string Name { get; set; } /// <summary> /// Gets or sets the description /// </summary> public virtual string Description { get; set; } /// <summary> /// Gets or sets the parent category identifier /// </summary> public virtual int ParentCategoryId { get; set; } /// <summary> /// Gets or sets a value indicating whether the entity is published /// </summary> public virtual bool Published { get; set; } /// <summary> /// Gets or sets a value indicating whether the entity has been deleted /// </summary> public virtual bool Deleted { get; set; } /// <summary> /// Gets or sets the display order /// </summary> public virtual int DisplayOrder { get; set; } /// <summary> /// Gets or sets the date and time of instance creation /// </summary> public virtual DateTime CreatedOn { get; set; } /// <summary> /// Gets or sets the date and time of instance update /// </summary> public virtual DateTime UpdatedOn { get; set; } }} |
3、\Libraries\Nop.Data\Mapping\News下面增加新闻类别映射类，因为nopcommerce使用Entity Framework (EF) Code-First方法， 允许你在nopcommerce代码中定义实体 (所有的核心实体类都在Nop.Core中定义)，所以必须在此添加映射类，代码如下：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
|
using System.Data.Entity.ModelConfiguration;using Nop.Core.Domain.News;namespace Nop.Data.Mapping.News{ public partial class NewsCategoryMap : EntityTypeConfiguration<NewsCategory> { public NewsCategoryMap() { this.ToTable("NewsCategory"); this.HasKey(bp => bp.Id); this.Property(bp => bp.Name).IsRequired().IsMaxLength(); this.Property(bp => bp.Description).IsRequired().IsMaxLength(); } }} |
4、\Libraries\Nop.Services\News下面的INewsService.cs和NewsService.cs增加新闻类别相关操作。 INewsService.cs整理后代码如下：

另外需要增加NewsExtensions.cs，主要用于新闻类别的排序（对无限极分类的排序等等），代码如下：

5、到此底层的数据操作已经基本完成，开始修改后台管理部分。 Nop.Admin\Models\News\增加新闻类别页面所需要的ViewModel，代码如下：

using System;using System.Collections.Generic;using System.Web.Mvc;using FluentValidation.Attributes;using Nop.Admin.Validators.News;using Nop.Web.Framework;using Nop.Web.Framework.Mvc;namespace Nop.Admin.Models.News{ [Validator(typeof(NewsCategoryValidator))] public class NewsCategoryModel : BaseNopEntityModel { public NewsCategoryModel() { AvailableCategories = new List<SelectListItem>(); } [NopResourceDisplayName("Admin.ContentManagement.News.NewsCategoryItems.Fields.Name")] public string Name { get; set; } [NopResourceDisplayName("Admin.ContentManagement.News.NewsCategoryItems.Fields.Description")] [AllowHtml] public string Description { get; set; } [NopResourceDisplayName("Admin.ContentManagement.News.NewsCategoryItems.Fields.ParentName")] public int ParentCategoryId { get; set; } [NopResourceDisplayName("Admin.ContentManagement.News.NewsCategoryItems.Fields.ParentName")] public string ParentCategoryName { get; set; } [NopResourceDisplayName("Admin.ContentManagement.News.NewsCategoryItems.Fields.Published")] public bool Published { get; set; } [NopResourceDisplayName("Admin.ContentManagement.News.NewsCategoryItems.Fields.DisplayOrder")] public int DisplayOrder { get; set; } [NopResourceDisplayName("Admin.ContentManagement.News.NewsCategoryItems.Fields.CreatedOn")] public DateTime CreatedOn { get; set; } public IList<SelectListItem> AvailableCategories { get; set; } }} |
Nop.Admin\Validators\News\增加类别的验证类NewsCategoryValidator.cs，主要用于后台添加时候的非空字数限制等等，代码如下：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17

using FluentValidation;using Nop.Admin.Models.News;using Nop.Services.Localization;namespace Nop.Admin.Validators.News{ public class NewsCategoryValidator : AbstractValidator<NewsCategoryModel> { public NewsCategoryValidator(ILocalizationService localizationService) { RuleFor(x => x.Name) .NotNull() .WithMessage(localizationService.GetResource("Admin.ContentManagement.News.NewsCategoryItems.Fields.Name.Required")); RuleFor(x => x.Description) .NotNull() .WithMessage(localizationService.GetResource("Admin.ContentManagement.News.NewsCategoryItems.Fields.Description.Required")); } }} |
修改Nop.Admin/MappingExtensions.cs文件，增加新闻类别相关内容，这几个方法主要是NewsCategory和NewsCategoryModel之间的相互转换，代码如下：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14

//news category items public static NewsCategoryModel ToModel(this NewsCategory entity) { return Mapper.Map<NewsCategory, NewsCategoryModel>(entity); } public static NewsCategory ToEntity(this NewsCategoryModel model) { return Mapper.Map<NewsCategoryModel, NewsCategory>(model); } public static NewsCategory ToEntity(this NewsCategoryModel model, NewsCategory destination) { return Mapper.Map(model, destination); } |
修改Nop.Admin/Infrastructure/AutoMapperStartupTask.cs文件，增加相关映射规则，如果不加的话会出错的哦， AutoMapper是基于对象到对象约定的映射工具，常用于（但并不仅限制于）把复杂的对象模型转为DTO，一般用于ViewModel模式和跨服务范畴。 AutoMapper给用户提供了便捷的配置API，就像使用约定来完成自动映射那样。 代码如下：
|
1
2
3
4
5
6
|
Mapper.CreateMap<NewsCategory, NewsCategoryModel>() .ForMember(dest => dest.AvailableCategories, mo => mo.Ignore()) .ForMember(dest => dest.ParentCategoryName, mo => mo.Ignore()) .ForMember(dest => dest.CreatedOn, mo => mo.Ignore()); Mapper.CreateMap<NewsCategoryModel, NewsCategory>() .ForMember(dest => dest.CreatedOn, mo => mo.Ignore()); |
最后修改Nop.Admin\Controllers\NewsController.cs，增加新闻类别的增删改查操作，如下：
