It seems that sqlobject does not allow for two SQLObject subclasses with
the same name:
>>> from sqlobject import SQLObject
>>> class A(SQLObject): pass
...
>>> try:
... class A(SQLObject): pass
... except:
... print "Oops!"
...
Oops!
In your scenario these are __main__.TextyDispleje and
displeje_pokus.TextyDispleye. While you could either alter the textfile to
>>> import __main__ as displeje_pokus
or the module along the lines of
# not recommended!
from displeje_pokus import TextyDispleje
if __name__ == "__main__":
# doctest
else:
class TextyDispleje(SQLObject):
pass
the clean way to fix the problem is to use a separate script to invoke the
doctest.
