Trouble Persisting non-content part data

Topics: Writing modules
Oct 7, 2011 at 7:40 AM

Hi, I'm getting a 'no persistor error' when trying to save my data. Any ideas?

I'm, actually integrating dhtmlx scheduler and it's close.  

namespace geoEvents {
    public class Migrations : DataMigrationImpl {

        public int Create() {
			SchemaBuilder.CreateTable("CalendarRecord", table => table
                .Column<int>("Id", column => column.PrimaryKey().Identity())
                .Column("text", DbType.String)
				.Column("start_date", DbType.DateTime)
                .Column("end_date", DbType.DateTime)
                .Column("rec_type", DbType.String)
                .Column("event_length", DbType.Int32)
                .Column("event_pid", DbType.Int32 )

The model used to be under models but in desperation tried under Records with same result..
namespace geoEvents.Records
    public class CalendarRecord 
        public int Id { get; set; }
        public virtual string text { get; set; }
        public virtual DateTime? start_date { get; set; }
        public virtual DateTime? end_date { get; set; }
        public virtual Int32 event_pid { get; set; }
        public virtual Int32 event_length { get; set; }
        public virtual String rec_type { get; set; }

Then I'm trying an insert in a controller..

namespace geoEvents.Controllers
    /// <summary>
    /// An ordinary ASP.NET MVC controller.
    /// You can create controllers and actions as in ordinary MVC applications.
    /// </summary>

    public class CalendarController : Controller

        private readonly IContentManager _contentManager;
        private readonly IContentDefinitionManager _contentDefinitionManager;
        private readonly ITransactionManager _transactionManager;
        private readonly ISiteService _siteService;

        private readonly IRepository<CalendarRecord> _repository;

        public IOrchardServices Services { get; set; }
        private readonly IOrchardServices _services;

        /// <summary>
        /// You can specify parameters in controller's ctor.
        /// Parameters will be injected by IoC controller with an appropriate object.
        /// IOrchardServices is the most commonly used object 
        /// - it is used to interact (get/save data from db, get request data and so on) with Orchard.
        /// </summary>
        /// <param name="services"></param>
        public CalendarController(IOrchardServices services, IRepository<CalendarRecord> repository, IContentManager contentmanager)
            _services = services;
            _repository = repository;
            _contentManager = contentmanager;


        public ActionResult Save(FormCollection actionValues)
            String action_type = actionValues["!nativeeditor_status"];
            Int64 source_id = Int64.Parse(actionValues["id"]);
            Int64 target_id = source_id;
            CalendarRecord MyEvent = new CalendarRecord();

                switch (action_type)
                    case "inserted":
                        MyEvent.text = actionValues["text"];
                        MyEvent.start_date = DateTime.Parse(actionValues["start_date"]);
                        MyEvent.end_date = DateTime.Parse(actionValues["end_date"]);
                        MyEvent.rec_type = actionValues["rec_type"];
                        if (MyEvent.rec_type.Length > 0)
                            MyEvent.event_length = actionValues["event_length"].Length > 0 ? Convert.ToInt32(actionValues["event_length"]) : 0;
                            MyEvent.event_pid = actionValues["event_pid"].Length > 0 ? Convert.ToInt32(actionValues["event_pid"]) : 0;
                        _repository.Create(MyEvent );

Error is: No persister for: geoEvents.Records.CalendarRecord

No handler?

No, no handler. I thought they were for part data only. How would it look?

Fixed it. Two days of futzing around and the issue was as simple as not declaring the Id as 'virtual'. Doh!

Yeah, you don't need a handler for non-part records. But thanks, geodiction, for posting the solution as I probably wouldn't have found it easily.

For the record and everyone else out there struggling with this error, here we go:
  1. Record classes must be located in a namespace that ends with either .Models or .Records (see \src\Orchard\Environment\ShellBuilders\CompositionStrategy.cs -> IsRecord(Type type)).
  2. All members in Record classes must be virtual, especially the Id field.
