小编Yan*_*Btd的帖子

我尝试使用ASP.Core来建立一个多语言网站.所以,我有我的StartUp.cs:

public void ConfigureServices(IServiceCollection services)
{
    services.AddLocalization();
    services.Configure<RequestLocalizationOptions>(
    opts =>
    {
        var supportedCultures = new[]
        {
            new CultureInfo("de-DE"),
            new CultureInfo("de"),
            new CultureInfo("fr-FR"),
            new CultureInfo("fr"),
        };
        opts.DefaultRequestCulture = new RequestCulture("fr-FR");
        // Formatting numbers, dates, etc.
        opts.SupportedCultures = supportedCultures;
        // UI strings that we have localized.
        opts.SupportedUICultures = supportedCultures;
    });
    // Add framework services.
    services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
    services.AddIdentity<ApplicationUser, IdentityRole>()
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders();
    services.AddMvc();
    // Add application services.
    services.AddTransient<IEmailSender, AuthMessageSender>();
    services.AddTransient<ISmsSender, AuthMessageSender>();
}

在我的_ViewImports.cs中我有:

@using System.Threading.Tasks
@using Microsoft.AspNetCore.Builder
@using Microsoft.AspNetCore.Localization
@using Microsoft.AspNetCore.Mvc.Localization
@using Microsoft.Extensions.Options …

我想像示例一样填充图表：https://www.chartjs.org/docs/latest/charts/bar.html

我收到此错误：

AttributeError at /timesheet/json-month/
Got AttributeError when attempting to get a value for field `working_hour` on serializer `TimesheetSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `str` instance.
Original exception text was: 'str' object has no attribute 'working_hour'.

有了这个模型：

class Timesheet(models.Model):
    owner = models.ForeignKey(User, on_delete = models.CASCADE)
    title = models.CharField(max_length = 64, verbose_name = _("Title"))
    date = models.DateField(default=datetime.datetime.now())
    working_hour = models.FloatField(verbose_name = _("Working time"))
    week = models.IntegerField(verbose_name = "working week") …

我将Asp.Core 2.1与“ Page Razor Crud”一起使用，并且希望在我的页面中显示一个下拉列表。

这是我的模型：

public enum EnumStatus
    {
        Waiting,
        [Display(Name = "Development progress")]
        Progress,
        Canceled,
        Refused,
        Deployed,
    }
    public class Improvement
    {
        [Key]
        public int ID { get; set; }

        public string Title { get; set; }

        [DataType(DataType.Text)]
        public string Description { get; set; }

        public EnumStatus Status { get; set; }
    }

CRUD Razor页面生成了以下行：

<select asp-for="Improvement.Status" class="form-control"></select>

但它是空的。经过研究，我发现我需要添加asp项目。但是在这一点上，我测试过的所有解决方案都失败了。

最好的祝福，
