Re: [dbfpy-devel] [Fwd: FPT Memo field implementation.]

[Yaroslav S. <ya...@gm...>]

Hi,

I personally don't think it's a good idea to pass DBF instance  
everywhere. Let's add this knowledge only if it's really needed (you  
say that FPT MEMO looks like the case). I would expect some factory  
(which always accepts DBF instances as an argument) which knows if DBF  
instance should be passed to the Field or not.
