javascript - 如果使用单个实体，使用自动映射器对我来说效果很好

Question

如果我要添加两个或多个实体，我必须在单个类中声明所有属性，以便将它们从 Ajax 调用中的 View 正确映射到 JS。

只是检查一下我是否遗漏了 AutoMapper 可以做但我没有利用的东西...

例如，如果仅使用一个实体(客户)，则 AutoMapper 中的以下内容可以正常工作:

Mapper.CreateMap<CustomerDTO, Customer>();
                    var customer = Mapper.Map<CustomerDTO, Customer>(custDTO);

如果使用两个或多个实体，我必须执行以下操作:

using (var dbcxtTrans = DbContext.Database.BeginTransaction(System.Data.IsolationLevel.RepeatableRead))
{
    Customer cust = new Customer();
    cust.Address1 = custProjDTO.customer_Address1;
    cust.Address2 = custProjDTO.customer_Address2;
    cust.CellPhone = custProjDTO.customer_CellPhone;
    cust.City = custProjDTO.customer_City;
    cust.Company = custProjDTO.customer_Company;
    cust.CreatedDate = custProjDTO.customer_CreatedDate;
    cust.Email = custProjDTO.customer_Email;
    cust.FirstName = custProjDTO.customer_FirstName;
    cust.HomePhone = custProjDTO.customer_HomePhone;
    cust.IMAddress = custProjDTO.customer_IMAddress;
    cust.LastName = custProjDTO.customer_LastName;
    cust.State = custProjDTO.customer_State;
    cust.UpdatedDate = custProjDTO.customer_UpdatedDate;
    cust.UserName = custProjDTO.customer_UserName;
    cust.Website = custProjDTO.customer_Website;
    cust.Zip = custProjDTO.customer_Zip;

    DbContext.Customers.Add(cust);
    await DbContext.SaveChangesAsync();

    Project proj = new Project();
    proj.CustomerID = cust.CustomerID;
    proj.CategoryID = custProjDTO.project_CategoryID;
    proj.CreatedDate = custProjDTO.project_CreatedDate;
    proj.Description = custProjDTO.project_Description;
    proj.Name = custProjDTO.project_Name;
    proj.Notes = custProjDTO.project_Notes;
    proj.PriorityID = custProjDTO.project_PriorityID;
    proj.Quote = custProjDTO.project_Quote;
    proj.StatusID = custProjDTO.project_StatusID;
    proj.UpdatedDate = custProjDTO.project_UpdatedDate;

    DbContext.Projects.Add(proj);
    await DbContext.SaveChangesAsync();

    dbcxtTrans.Commit();
}

这是因为我的属性名称必须与 View 中的名称对齐(见下文)

@model YeagerTechDB.ViewModels.Customers.CustomerProject

    ViewBag.Title = "Create Customer & Project";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

                contentCreateCustomerProject();
        });
    </script>
}

反过来，它必须与我的 JS 属性保持一致:

var customerProject_Input = {
        customer_UserName: $('#customer_UserName').val(),
        customer_Email: $('#customer_Email').val(),
        customer_Company: $('#customer_Company').val(),
        customer_FirstName: $('#customer_FirstName').val(),
        customer_LastName: $('#customer_LastName').val(),
        customer_Address1: $('#customer_Address1').val(),
        customer_Address2: $('#customer_Address2').val(),
        customer_City: $('#customer_City').val(),
        customer_State: $('#customer_State').val(),
        customer_Zip: $('#customer_Zip').val(),
        customer_HomePhone: $('#customer_HomePhone').val(),
        customer_CellPhone: $('#customer_CellPhone').val(),
        customer_Website: $('#customer_Website').val(),
        customer_IMAddress: $('#customer_IMAddress').val(),
        customer_CreatedDate: currdate,
        customer_UpdatedDate: null,
        project_Name: $('#project_Name').val(),
        project_Description: $('#project_Description').val(),
        project_CategoryID: $('#project_CategoryID').val(),
        project_PriorityID: $('#project_PriorityID').val(),
        project_StatusID: $('#project_StatusID').val(),
        project_Quote: $('#project_Quote').val(),
        project_Notes: $('#project_Notes').val(),
        project_CreatedDate: currdate,
        project_UpdatedDate: null
    };

由于两个类中的属性名称不同，请尝试创建详细的映射配置，例如:

Mapper.CreateMap<Customer, CustomerDTO>()
    .ForMember(dest => dest.Address1, 
        opts => opts.MapFrom(src => src.customer_Address1))
    .ForMember(dest => dest.Address2, 
        opts => opts.MapFrom(src => src.customer_Address2))
    .ForMember(dest => dest.CellPhone, 
        opts => opts.MapFrom(src => src.customer_CellPhone))
    .ForMember(dest => dest.City, 
        opts => opts.MapFrom(src => src.customer_City))
    .ForMember(dest => dest.Company, 
        opts => opts.MapFrom(src => src.customer_Company))
    .ForMember(dest => dest.CreatedDate, 
        opts => opts.MapFrom(src => src.customer_CreatedDate))
    .ForMember(dest => dest.Email, 
        opts => opts.MapFrom(src => src.customer_Email))
    .ForMember(dest => dest.FirstName, 
        opts => opts.MapFrom(src => src.customer_FirstName))

此外，为了保存对象，您不需要调用以下两次:

await DbContext.SaveChangesAsync();

只做一次:

 DbContext.Projects.Add(proj);
 DbContext.Customers.Add(cust);
 await DbContext.SaveChangesAsync();
