Snippet Code for Creating FeedItem.
- Most of time user easily create feedItem but it seems that file created is not Previewable.
The only solution to it is add extension to ContentFileName.
for(Attachment att : [SELECT id,body,parentId FROM ]
{
Blob body = att.body;
String name = (att.name).substringBeforeLast('.');
String extension = (att.name).substringAfterLast('.');
FeedItem file = new FeedItem();
file.ParentId = String.valueof(att.parentid) ; // ID of parent object of file (Record Id)
file.ContentData = body;
file.ContentFileName = name + '.' + extension;
file.Title = name;
System.debug('file::' + file);
feedItemList .add(file);
}
If(feedItemList.size() > 0)
{
insert feedItemList;
}
File will get Show up in File related list of Record(Parent id).
