我創建了一個自定義部分，將使用管理界面的淘汰賽保存IEnumerable日期列表。Orchard CMS保存額外的JSON數據
一切工作正常，除了我不知道怎麼去張貼的JSON數據，推到數據庫...
型號
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; }
}
}
遷移
public class Migrations : DataMigrationImpl {
public int Create() {
// Creating table ImportantDatesRecord
SchemaBuilder.CreateTable(typeof(ImportantDateListRecord).Name, table => table
.ContentPartRecord()
.Column<string>("Title")
);
// make the date list part attachable
ContentDefinitionManager.AlterPartDefinition(typeof(ImportantDateListPart).Name,
builder => builder.Attachable());
// Creating table ImportantDateRecord
SchemaBuilder.CreateTable("ImportantDateRecord", table => table
.Column("Id", DbType.Int32, c => c.Identity())
.Column("Title", DbType.String)
.Column("Date", DbType.DateTime)
.Column("Descripiton", DbType.String)
);
return 1;
}
}
驅動程序
namespace HappyCity.Parts.Drivers {
[OrchardFeature("HappyCity.Parts.ImportantDates")]
public class ImportantDatesDriver: ContentPartDriver<ImportantDateListPart> {
// This prefix will be used to distinguish between similarly named input fields when building the editor form
protected override string Prefix
{
get { return "HappyCity.Parts.ImportantDates.ImportantDateListPart"; }
}
// This method gets called when building the display shape of the content item the part is attached to.
protected override DriverResult Display(ImportantDateListPart part, string displayType, dynamic shapeHelper)
{
return ContentShape("Parts_ImportantDates",
() => shapeHelper.Parts_ImportantDates(DisplayType: displayType));
}
//GET
protected override DriverResult Editor(ImportantDateListPart part, dynamic shapeHelper) {
return ContentShape("Parts_ImportantDates_Edit",
() => shapeHelper.EditorTemplate(
TemplateName: "Parts/ImportantDates",
Model: part,
Prefix: Prefix));
}
//POST
protected override DriverResult Editor(
ImportantDateListPart part, IUpdateModel updater, dynamic shapeHelper) {
updater.TryUpdateModel(part, Prefix, null, null);
return Editor(part, shapeHelper);
}
}
}
處理器
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);
//}
});
}
服務
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;
}
}
某處在處理，我應該能夠得到張貼在申請新的值。但是如何？
同樣在服務器上的SaveDate方法中，我不需要_importantDatesRepostiroy.update嗎？
