[SQLObject] "type checking" in SQLObject

[Ivo v. d. W. <iv...@am...>]

Hi,

I regularly run into weird problems because I'm trying to pass the wrong type of 
object to, for example, a foreign key.

How hard would it be to make SQLObject warn in such cases? I.e.

class a(SQLObject):
     x = StringCol() # x = dummy
class b(SQLObject):
     x = StringCol()
class c(SQLObject):
     x = StringCol()
     b = ForeignKey("b")

after these declarations, SQLObject will silently allow:

foo = c(x="", b=a())
(or)
foo.b = a()

If you have enough classes, selects(), code, etc, it's pretty easy to mixup 
arguments, results, classes, etc. An extra check would be very welcome.

Anyone else experiencing this as well?

Cheers

	Ivo
