I have a small code with this:
db.define_table('book',
Field('name',requires = IS_NOT_EMPTY()),
Field('category',
requires =
IS_IN_SET(['Politics','Finance','Fiction','Wellness']),
default = 'Politics'),
Field('price', 'integer',requires = IS_NOT_EMPTY()),
Field('image','upload'),
Field('selling_type',requires =
IS_IN_SET(['Bids','Buy']),default = 'Bid'),
Field('book_author',
db.auth_user,
default=auth.user_id,
writable=False,
readable=False,
requires=IS_IN_DB(db,
db.auth_user.id,'%(first_name)s')),
Field('description','text',requires = IS_NOT_EMPTY()),
Field('created_on','datetime',
default=request.now,
update=request.now,
writable=False))
product = db(book_author.id==db.book.book_author).select(db.book.ALL)
But I get this Error:
product = db(book_author.id==db.book.book_author).select(db.book.ALL)
AttributeError: 'NoneType' object has no attribute 'id'
