[Nitro] OgFile OgImage and my problems

[Michael Fellinger]

Hey List,

Now i wanted to post a perfect and polished version of OgFile OgImage and 
Thumbnail, my latest generally useful og-objects... but somehow that didn't 
work out so well.

I am stuck, right before i could add the last polishing because of something 
that must be quite obvious. I've just attached model and controller for now, 
i would be very glad if someone could help me - the problem is following:

OgImage creates Thumbnails, but i cannot assign the thumbnails to the OgImage 
that calls them.
I have tired various ways...
OgImage[@oid].thumbnails << (thumb = Thumbnail.new) # => method_missing '<<'
@thumbnails << ..... # => method_missing....
add_thumbnail(thumb)
self.add_thumbnail(thumb)
OgImage[@oid].add_thumbnail(thumb) # all of the three have no effect
thumb.og_image_oid = @oid # => no error, nothing happens
Thumbnail[thumb.oid].og_image_oid = @oid #=> same again
Thumbnail.find_by_oid(thumb.oid).og_image_oid = @oid #=> nothing ever happens

and about 20 other variants before of after the thumb.save! - what the heck am 
i doing wrong? i'm running out of ideas, and something seems to be flawed 
here...
Everytime i check the database (using sqlite for testing), no og_image_oid is 
assigned, also i wonder why OgImage doesn't get a proper linkage to the 
thumbnails... it looks quite unaffected

well, that's it, i appreciate every helping hand
