Ops, you are right, LazyForeignKey is quite new and is not available on
pypi yet.
Just specify the relation secondary with a lambda and declare user_sample_table
after Sample and replace the LazyForeignKey with a ForeignKey(Sample.uid).
Like:
from tgext.pluggable import app_model
class Sample(DeclarativeBase):
__tablename__ = 'plutest1_samples'
uid = Column(Integer, autoincrement=True, primary_key=True)
name = Column(Unicode(16))
user = relation(lambda: app_model.User, secondary=lambda:
user_sample_table)
user_sample_table = Table('tg_user_sample', app_model.metadata,
Column('user_id', Integer, ForeignKey(app_model.User.user_id),
primary_key=True),
Column('sample_id', Integer, ForeignKey(Sample.uid), primary_key=True)
)
