File "<console>", line 1, in <module>
File "/home/mengu/web2py/gluon/sql.py", line 1265, in __getattr__

writable=False),
Field('user', db.auth_user)

db.define_table('comments',
Field('post', db.posts),
Field('author', 'string'),
Field('body', 'string', length=500),
Field('dateline', 'datetime', default=request.now, writable=False)
)
db.define_table('categories',
Field('title', 'string'),
Field('slug', 'string', length=200),
Field('postcount', 'integer')

db.define_table('relations',
Field('post', db.posts),
Field('category', db.categories)
