Access/Modify Dynamic Data

Posted by Community Admin on 07-Apr-2011 00:00

Hi,

I've created a Dynamic Type like this :

App.WorkWith()

.DynamicData()

.Type()

.CreateNew("Lexique", "Telerik.Sitefinity.DynamicTypes.Model")

.Do(dt => dt.DatabaseInheritance = Telerik.Sitefinity.Metadata.Model.DatabaseInheritanceType.vertical)

.Field()

.TryCreateNew("acronym", typeof(string), ref changedDB)

.Done()

.Field()

.TryCreateNew("description", typeof(string), ref changedDB)

.Done()

.SaveChanges(true);

Now I want to access/add new data to the database to the Lexique table.
The tutorials in documentation show only when the document library is extended then accessed from the

App.WorkWith()

.Documents()

.Where(item => item.Parent.Title == "JobApplications" && item.Status == ContentLifecycleStatus.Live)

But since I am using a separate type, I want to know how do I access elements from the type I've just created.

Thank you.

Hello martani,

Currently there is no a common facade or manager that will allow you to use your custom type directly and you have to use a custom manager and WCF RESTful service to update the data for your custom type. You can take a look at our Products sample that comes with SDK installation.

There is a task in our TODO list about implementing common facade.

Thank you for your answer.

Knowing that, I've tried to come up with something similar to the Intermedite Jobs module (My module would just be a dictionary of items with an acronym and description thus the Products Module sounds to be very complicated in my case).

I followed exactly the instructions in the documentation along with making sure to not miss anything from the project from the SDK, my module builds successfully, but once on Sitefinity I get this erros message.

The type Lexique.Data.OpenAccessLexiqueDataProvider is not interceptable.

Parameter name: typeToIntercept

This is the stack trace :

[ArgumentException: The type Lexique.Data.OpenAccessLexiqueDataProvider is not interceptable.

Parameter name: typeToIntercept]

System.Web.UI.Control.PreRenderRecursiveInternal() +240

System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3914

There is no mention for the App.config file on the tutorial, and so far I can say that it is impossible for a beginner to develop a module so far. I've been trying for a month now, and adding dynamic fields to existing types doesn't seem promising for me, since I can have hundreds of items!

I appreciate your help.

Hello martani,

This looks like as an issue with the data model. I see that you use RadGrid to bind your data and this calls OpenAccessLexiqueDataProvider . Can you send the data provider implementation?

Thank you for your quick reply, this is my class OpenAccessLexiqueDataProvider

02. class OpenAccessLexiqueDataProvider: LexiqueDataProviderBase, IOpenAccessDataProvider

03.

04. #region IOpenAccessDataProvider Members

22.

23. return true;

26.

27. public Assembly[] GetPersistentAssemblies()

28.

29. return new[] typeof(LexiqueItem).Assembly ;

30.

31. #endregion

32.

33. public override LexiqueItem CreateLexiqueItem()

34.

35. return this.CreateLexiqueItem(new Guid());

36.

37.

38. public override LexiqueItem CreateLexiqueItem(Guid guid)

39.

40. var dateValue = DateTime.UtcNow;

41.

42. var item = new LexiqueItem()

43.

44. Id = guid,

45. ApplicationName = this.ApplicationName,

46. Owner = SecurityManager.GetCurrentUserId(),

47. DateCreated = dateValue,

48. PublicationDate = dateValue

49. ;

50.

51. ((IDataItem)item).Provider = this;

52.

53. if (guid != Guid.Empty)

54.

55. this.GetScope().Add(item);

56.

57.

58. return item;

59.

60.

61. public override IQueryable<LexiqueItem> GetLexiqueItems()

62.

63. var appName = this.ApplicationName;

64.

65. var query =

66. SitefinityQuery

67. .Get<LexiqueItem>(this, MethodBase.GetCurrentMethod())

68. .Where(b => b.ApplicationName == appName);

69.

70. return query;

79. ((IDataItem)item).Provider = this;

80. return item;

81.

82.

83. public override void DeleteLexiqueItem(LexiqueItem item)

84.

85. var scope = this.GetScope();

86. if (scope != null)

87.

88. scope.Remove(item);

89.

90.

I am doing an exact imitation of the OpenAccessJobsDataProvider class in the Intermediate Jobs module.

Thank you.

Hello martani,

The implementation looks fine, so the problem could be in the enhancer. If you want you can open a support request and send the module implementation to us.

Is there any way you could share your work/bring back the solution to these forums? I'm having the same issue with this code.

Posted by Community Admin on 05-May-2011 00:00

I gave up, till some documentation shows up maybe

I am having the same issue when trying to imitate OpenAccessJobsDataProvider class, I was developing modules in 3.7 it was so easy, now it looks like a nightmare in 4.1, did anyone find any solution for this?
