Question

该项目正在创建一个网上商店。我搭建了所有的身份文件，并创建了一个相同的视图/模型（剃刀页面），就像身份中的一个，但现在用于添加地址信息。我正在尝试创建一个可以在其中添加地址信息的表格，因此注册时不包括该信息。为了存储数据，我们使用PostgresQL，并且通过迁移成功创建了数据库。

地址模型（错误发生在user.name = model.name等；），他无法识别任何变量（姓氏，街道编号等）

namespace bytme.Areas.Identity.Pages.Account.Manage
{
public class AddressModel : PageModel
{
    private readonly UserManager<IdentityUser> _userManager;
    private readonly SignInManager<IdentityUser> _signInManager;
    private readonly ILogger<AddressModel> _logger;

    public AddressModel(
        UserManager<IdentityUser> userManager,
        SignInManager<IdentityUser> signInManager,
        ILogger<AddressModel> logger)
    {
        _userManager = userManager;
        _signInManager = signInManager;
        _logger = logger;
    }

    }

    public void OnGet(string returnUrl = null)

        ReturnUrl = returnUrl;

@{

@Html.Partial("_StatusMessage", Model.StatusMessage)
<div class="row">
    <div class="col-md-6">

UserModel，它扩展到IdentityUser

namespace bytme.Models
{
public class UserModel : IdentityUser
    {
    public override string Id { get; set; }
    public override string Email { get; set; }
    public override string UserName { get; set; }
    public override string PasswordHash { get; set; }
    public string zipcode { get; set; }
    public string city { get; set; }
    public string street { get; set; }
    public string streetnumber { get; set; }
    public string name { get; set; }
    public string surname { get; set; }
      }
}

Startup.cs

namespace bytme
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<CookiePolicyOptions>(options =>
            {
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseNpgsql(
                    Configuration.GetConnectionString("DefaultConnection")));

            services.AddIdentity<UserModel, IdentityRole>().AddEntityFrameworkStores<ApplicationDbContext>();

            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseDatabaseErrorPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseAuthentication();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

谢谢！

您正在使用UserManager<IdentityUser>，而应该使用UserManager<UserModel>。 IdentityUser实例未定义name属性，您在UserModel类中定义了此属性。要解决您的问题，您应该做两件事：

1）转到Startup.cs => ConfigureServices method，添加：

 services.AddIdentity<UserModel, IdentityRole>()
    .AddEntityFrameworkStores<YourDatabaseContextClassNameHere>()
    .AddDefaultTokenProviders();

2）注入UserManager<UserModel> userManager和SignInManager<UserModel> signInManager而不是UserManager<IdentityUser> userManager和SignInManager<IdentityUser> signInManager

IdentityUser不包含“名称”的定义
