Progromatic Album and Image Creation Issue - Sitefinity - Front- & Back-End Development

I am able to programmatically create an album, and images. But when I try to publish the images I get the following error.

Telerik.Sitefinity.Libraries.Model.Album, Telerik.Sitefinity.Model was not granted ManageImage in Image for principals with IDs 00000000-0000-0000-0000-000000000000

Note: This code is "simplified" greatly, but shows the flow of my actual implementation to a degree.

bool origSuppressSecurityChecksValue = WorkflowManager.GetManager().Provider.SuppressSecurityChecks;

LibrariesManager libMgr = LibrariesManager.GetManager();

Album album = libMgr.GetAlbums().SingleOrDefault(i => i.Title == BlogImageLibraryName);

if (album == null)

libMgr.Provider.SuppressSecurityChecks = true;

//Create the album.

album = libMgr.CreateAlbum();

//Set the properties of the album.]

//Recompiles and validates the url of the album.

libMgr.RecompileAndValidateUrls(album);

//Save the changes.

libMgr.SaveChanges();

libMgr.Provider.SuppressSecurityChecks = false;

string imageTitle = Path.GetFileNameWithoutExtension(fileName);

Image image = album.Images().FirstOrDefault(i => i.Title == imageTitle);

if (image == null)

libMgr.Provider.SuppressSecurityChecks = true;

image = libMgr.CreateImage(); // actually create an image

image.Parent = album;

[//Set the properties of the album post.]

//Upload the image file.

libMgr.Upload(image, imageStream, Path.GetExtension(fileName));

//Save the changes.

libMgr.SaveChanges();

libMgr.Provider.SuppressSecurityChecks = false;

//Publish the Albums item. The live version acquires new ID.

var bag = new Dictionary<string, string>();

bag.Add("ContentType", typeof(Image).FullName);

WorkflowManager.GetManager().Provider.SuppressSecurityChecks = true;

// THIS LINE WILL THROW THE EXCEPTION ABOVE

WorkflowManager.MessageWorkflow(image.Id, typeof(Image), null, "Publish", false, bag);

I'm missing a concept here somehow...maybe the default provider is not the one I need for the Workflow Suppress?

Hi Stephen,

You can use this code to create a new image and publish it:

var librariesManager = LibrariesManager.GetManager(LibrariesManager.GetDefaultProviderName());

// Create a new image

var image = librariesManager.CreateImage();

// Assign the right library based on the culture

if (Equals(culture, CultureInfo.GetCultureInfo("nl"))) image.Parent = parentNl;

if (Equals(culture, CultureInfo.GetCultureInfo("en"))) image.Parent = parentUs;

image.Title[culture] = title;

image.UrlName[culture] = Regex.Replace(title.ToLower(), UrlNameCharsToReplace, UrlNameReplaceString);

// Set the right workflow state

image.ApprovalWorkflowState.Value = ApprovalWorkflowStatePublished;

// Upload

librariesManager.Upload(image, foundFile.OpenRead(), foundFile.Extension);

librariesManager.RecompileItemUrls(image);

// Publish

librariesManager.Lifecycle.Publish(image, culture);

// Save changes

librariesManager.SaveChanges();

I use this static string to hold the right workflow state

public static readonly string ApprovalWorkflowStatePublished = "Published";

It is easier to use the LifeCycle methods from the manager, rather than the WorkFlowManager.

I hope this is of any help.

Best regards,
Daniel

It sure was Daniel - was exactly what I needed! Everything else went smoothly, and now this is as well.

Thank you, kindly!
