id = Column(Integer, primary_key=True)
keywords = relationship("Keyword", secondary=keywords)
+Like other :func:`.relationship` arguments, a string is accepted as well,
+passing the string name of the table as defined in the ``Base.metadata.tables``
+ __tablename__ = 'authors'
+ id = Column(Integer, primary_key=True)
+ keywords = relationship("Keyword", secondary="keywords")
As with traditional mapping, its generally not a good idea to use
a :class:`.Table` as the "secondary" argument which is also mapped to
a class, unless the :class:`.relationship` is declared with ``viewonly=True``.
