Could anybody explain the following traceback to me?
db.define_table...
Field('slug', unique=True, required=True),
....
)
db.page.slug.requires = IS_NOT_IN_DB(db, 'page.slug')
form = SQLFORM.factory(db.page.slug, Field('tags'))
Produces the following error on form.accepts(), works fine if without the
validator
