I created a custom content type. It includes a custom content part and the builtin commonpart.

From my custom module, I programmatically create and edit this content part. When created, the fields for commonpart is created as well, but when editing I have to manually enter the values (ie. ModifiedUTC, PublishedUTC) within code.

Do I miss something? Shouldn't the commonpart automatically update those values?

That's probably because you are doing it through custom code. The code that handles this when going through the normal pipeline is in CommonPartHandler.cs.

Yes, I'm doing it through custom code. What's the proper way of doing this?

Jun 27, 2011 at 10:25 PM

Of doing what? Are you going through the ContentManager?

Yes I am. I use the below code to update my custom content (book) item from the values of a viewmodel.

            BookPart book = _orchardServices.ContentManager.Get<BookPart>(bookId, VersionOptions.Latest);

            book.Title = model.BookTitle;
            book.Author = model.BookAuthor;

            book.As<CommonPart>().ModifiedUtc = DateTime.UtcNow;
            book.As<CommonPart>().PublishedUtc = DateTime.UtcNow;

That should only set the publication date on the part and version, not the modified date.

I think I may find the way to fill in all related fields. What I want to learn is the way of doing this automatically. Like when ContentManager.Create() is called.

Well, if you follow the code in Create, it is calling the handlers for Creating, Created, Publishing and Published.

I tried to follow the process in Comments module. However, I realized that the Comments module itself does not update the ModifiedUtc CommonPart field when the associated Comment content is updated.

Shouldn't it be updated?

Probably yes.

Then, I'll file a bug for this issue.

By the way, I still feel that if a content type includes the built-in CommonPart and the CRUD operations are handled via ContentManager, then the CommonPart should automatically update its fields after each operation.

Thanks. You could also submit a patch with the bug report.

There are cases where no, you don't want to systematically update those dates (import is one example).
