requires=IS_NOT_EMPTY(), ondelete='CASCADE',
notnull=False, unique=False,
uploadfield=True, widget=None, label=None, comment=None,
uploadfield=True, # True means store on disk,
# 'a_field_name' means store in this field in db
# False means file content will be discarded.
writable=True, readable=True, update=None, authorize=None,
autodelete=False, represent=None, uploadfolder=None)
to be used as argument of SQLDB.define_table
allowed field types: string, boolean, integer, double, text, blob,

default or they will be required in SQLFORMs the requires argument is
used to validate the field input in SQLFORMs
