Hi Masters!
I have a problem with Tutorial wiki2.
When i'm going step by step, everything is OK till i have to edit
scripts/populate.py
„Since we’ve changed our model, we need to make changes to our
populate.py script. In particular, we’ll replace our import of MyModel
with one of Page and we’ll change the very end of the script to create
a Page rather than a MyModel and add it to our DBSession.”
I've changed
from ..models import (
DBSession,
Page, # <-here
Base,
)
and at the end of a script:
DBSession.configure(bind=engine)
Base.metadata.create_all(engine)
with transaction.manager:
model = Page(name='newOne', data='whatever') # <--here,
whatever, some text
DBSession.add(model)
but now
$ ../bin/python setup.py test -q
gives me lots of errors, last line is
AttributeError: 'module' object has no attribute 'views'
and
$ ../bin/populate_tutorial development.ini

Could somebody help me?
