Create block programmatically

Vote:
 

Hi,

I'm writing a script for data migration. I have a problem when creating the block.

You can create a page with the following code:

            var caAttribute = typeof(TResult).GetCustomAttributes(typeof(ContentTypeAttribute), true).FirstOrDefault() as ContentTypeAttribute;
            if (caAttribute != null)
            {
                Guid pageGuid;
                Guid.TryParse(caAttribute.GUID, out pageGuid);

                if (pageGuid != Guid.Empty)
                {
                    var pageTypeRepository = ServiceLocator.Current.GetInstance();
                    var child = ContentRepository.GetDefault(parentLink, pageTypeRepository.Load(pageGuid).ID);
                    child.PageName = newPageName;
                    ContentRepository.Save(child, SaveAction.Publish, AccessLevel.NoAccess);//todo check AvailablePageTypes attribute - it can block created page
                    return child;
                }
            }

            return null;

How can I get a similar result for the block?

Use ContentTypeRepository instead and then you need to cast child to IContent in the Save method:

var caAttribute = typeof(TResult).GetCustomAttributes(typeof(ContentTypeAttribute), true).FirstOrDefault() as ContentTypeAttribute;
if (caAttribute != null)
{
    Guid contentGuid;
    Guid.TryParse(caAttribute.GUID, out contentGuid);

    if (contentGuid != Guid.Empty)
    {
        var contentTypeRepository = ServiceLocator.Current.GetInstance<ContentTypeRepository>();
        var child = ContentRepository.GetDefault<TResult>(parentLink, contentTypeRepository.Load(contentGuid).ID);
        child.Name = newPageName;
        ContentRepository.Save((IContent)child, SaveAction.Publish, AccessLevel.NoAccess);//todo check AvailablePageTypes attribute - it can block created page
        return child;
    }
}

return null;

This code will work for both pages and blocks.

Btw, why are you parsing the content type guid from the model? GetDefault() should handle that for you. This should be enough:

var child = ContentRepository.GetDefault<TResult>(parentLink);
child.Name = newPageName;
ContentRepository.Save((IContent)child, SaveAction.Publish, AccessLevel.NoAccess);
return child;

Hi Johan,

I realized where I was wrong because of your answers. Here is the result:

        public static TResult CreateBlockForPage<TResult>(ContentReference pageReference, string newBlockName, 
            SaveAction saveAction = SaveAction.Publish, AccessLevel accessLevel = AccessLevel.NoAccess)
            where TResult : BlockData
        {
            var assetsFolderForPage = ServiceLocator.Current
                .GetInstance<ContentAssetHelper>()
                .GetOrCreateAssetFolder(pageReference);

            var blockInstance = ContentRepository.GetDefault<TResult>(assetsFolderForPage.ContentLink);
            var blockForPage = blockInstance as IContent;
                                  
            blockForPage.Name = newBlockName;

            ContentRepository.Save(blockForPage, saveAction, accessLevel);
            return blockInstance;
        }

Thanks

Hi all,

Just to tag on the back of this thread.

I am currently trying to achieve the same thing, however, what I am struggling with at the moment is how to set the display options for the block programatically.

Has anyone any advice on this?

Thanks

Adam
