[TYPO3-mvc] Abstract Classes and the DB

[Lienhart Woitok]

Hello Zalán,

have you tried it this way? I think it should work in this manner, I have done a similar thing with an abstract base class and extending classes. This worked quite well for me.

So I think if you have problems, there might be something wrong with your implementation.

Kind regards,

Hello,

Thanks for the quick answer.

>> 1) Is it possible to create repositories of abstract classes in extbase?
>> 2) Is it possible to save and retrieve (!) an abstract class with single table inheritance?

Hm. That means you have to break with the naming conventions... That's not very good ;( ...
What's the matter if we use Concrete Table Inheritance? Is the naming issue the same?

> But as I said, I'm not entirely sure. I of course use STI but I didn't declare my BaseModels as abstract for some reason I can't remember now.

My problem is that I have to make sure that every subclass has to implement a given method, but I can't use interfaces fpr that because there are other (gerneral) methods that are implemented in the abstract class. I have a scheme like this:

                        AbstractMediaItem
                             /                      \
            AbstractStream         AbstractFile
               /                                               \
      Video      Audio, etc.             Video, Audio, etc.

Is it possible to make a structure with more than one abstract instance like the one I described.

Regards,
Zalán
