Orchard CMS保存其他JSON数据

我正在创建一个自定义部件，该部件将使用管理UI的剔除功能保存一个IEnumerable日期列表。

一切正常，除了我不确定如何获取发布的json数据，将其推入数据库...

模型

namespace HappyCity.Parts.Models {

    [OrchardFeature("HappyCity.Parts.ImportantDates")]
    public class ImportantDateListRecord : ContentPartRecord {
        public virtual string Title { get; set; }
    }

    [OrchardFeature("HappyCity.Parts.ImportantDates")]
    public class ImportantDateListPart : ContentPart<ImportantDateListRecord> {

        public string Title {
            get { return Record.Title; }
            set { Record.Title = value; }
        }

        public string JsonDates { get; set; }


        private readonly LazyField<IEnumerable<ImportantDateRecord>> _importantDates = new LazyField<IEnumerable<ImportantDateRecord>>();
        public LazyField<IEnumerable<ImportantDateRecord>> ImportantDatesField { get { return _importantDates; } }
        public IEnumerable<ImportantDateRecord> ImportantDates
        {
            get { return _importantDates.Value; }
        }

    }

    [OrchardFeature("HappyCity.Parts.ImportantDates")]
    public class ImportantDateRecord 
    {
        [JsonProperty("id")]
        public virtual int Id { get; set; }

        [JsonProperty("title")]
        public virtual string Title { get; set; }

        [JsonProperty("date")]
        public virtual DateTime? Date { get; set; }

        [JsonProperty("description")]
        public virtual string Descripiton { get; set; }
        //public virtual string Link { get; set; }
    }

}

处理程序

public ImportantDatesHandler(IRepository<ImportantDateListRecord> repository , Work<IImportantDatesManager> importantDatesManager)
        {
            Filters.Add(StorageFilter.For(repository));

            OnActivated<ImportantDateListPart>((context, part) =>
            {
                part.ImportantDatesField.Loader(() => importantDatesManager.Value.GetDates());
            });


            OnUpdating<ImportantDateListPart>((context, part) =>
            {

                var JsonDates = part.JsonDates;
                // ***** this just gives me the current dates from the db not the ones poseted in the form. 


                // ***** if i create a list of dates like this they will be saved to the database
                //var dates = new List<ImportantDateRecord>();
                //dates.Add(new ImportantDateRecord
                //{
                //    Title = "test date",
                //    Date = new DateTime(1977, 8, 15),
                //    Descripiton = "lorem ipsum blur"
                //});


                //foreach (var importantDateRecord in JsonDates)
                //{
                //    importantDatesManager.Value.SaveDate(importantDateRecord);
                //}

            });

        }

服务

 public interface IImportantDatesManager : IDependency
    {
        IEnumerable<ImportantDateRecord> GetDates();
        IEnumerable<ImportantDateRecord> GetDates(int maxCount);
        void SaveDate(ImportantDateRecord importantDate);

    }

    [OrchardFeature("HappyCity.Parts.ImportantDates")]
    public class ImportantDatesManager : IImportantDatesManager {

        private readonly IRepository<ImportantDateRecord> _importantDatesRepostiory;


        public ImportantDatesManager(IRepository<ImportantDateRecord> importantDatesRepostiory) {
            _importantDatesRepostiory = importantDatesRepostiory;
        }


        public IEnumerable<ImportantDateRecord> GetDates() {
            return _importantDatesRepostiory.Table.AsEnumerable();
        }

        public IEnumerable<ImportantDateRecord> GetDates(int maxCount) {
            return _importantDatesRepostiory.Table.Take(maxCount);
        }

        public void SaveDate(ImportantDateRecord importantDate) {
            // Let's also practice exception handling.
            if (String.IsNullOrEmpty(importantDate.Title)) throw new ArgumentNullException("importantDate", "Title was null");

            var date = _importantDatesRepostiory.Fetch(record => record.Id == importantDate.Id).FirstOrDefault();

            if (date == null)
            {
                date = new ImportantDateRecord();
                _importantDatesRepostiory.Create(date);
            }

            date.Title = importantDate.Title;
            date.Date = importantDate.Date;
            date.Descripiton = importantDate.Descripiton;
        }
    }

在处理程序中的某个位置，我应该能够获取请求中发布的新值。但是如何？

同样在服务器上的SaveDate方法中，我不需要_importantDatesRepostiroy.update吗？
