modified welcome app- in models/db.py commented out this block- if not request.env.web2py_runtime_gae: / else: ..and replaced with- db = DAL('sqlite://storage.sqlite', lazy_tables=True, ignore_field_case=False, pool_size=10, check_reserved=['postgres', 'postgres_nonreserved']) created models/db_data.py and added- db.define_table('datatable', Field('title', length=128), Field('name', requires=IS_IN_SET(['a','b','c'], multiple=False, zero=None), readable=False, writable=False, length=128), Field('dtype', requires=IS_IN_SET(['1','2','3'], multiple=False), label="Type", readable=False, writable=False, length=128), Field('finished', 'boolean', default=False, readable=False, writable=False), Field('the_timestamp', 'datetime', readable=False, writable=False), Field('alive', 'boolean', default=True, readable=False, writable=False), Field( 'comments', 'text' ), auth.signature, migrate=True, format = '%(title)s %(datatype)s %(species)s' ) created welcome/databases folder ------------ launched with- python '.../web2py.py' -S welcome -M >>> from datetime import datetime ## insert two fields- >>> new_record = db.datatable.validate_and_insert(dtype='1', the_timestamp=datetime.utcnow()) Traceback (most recent call last): File "<console>", line 1, in <module> File ".../gluon/packages/dal/pydal/objects.py", line 749, in validate_and_insert response, new_fields = self._validate_fields(fields) File ".../gluon/packages/dal/pydal/objects.py", line 741, in _validate_fields value, error = self[fieldname].validate(raw_value) File ".../gluon/packages/dal/pydal/objects.py", line 1634, in validate (value, error) = validator(value) File ".../gluon/validators.py", line 660, in __call__ if isinstance(value, (int, long)) or value.isdigit(): AttributeError: 'NoneType' object has no attribute 'isdigit' ## no fields- >>> new_record = db.datatable.validate_and_insert() Traceback (most recent call last): File "<console>", line 1, in <module> File ".../gluon/packages/dal/pydal/objects.py", line 749, in validate_and_insert response, new_fields = self._validate_fields(fields) File ".../gluon/packages/dal/pydal/objects.py", line 741, in _validate_fields value, error = self[fieldname].validate(raw_value) File ".../gluon/packages/dal/pydal/objects.py", line 1634, in validate (value, error) = validator(value) File ".../gluon/validators.py", line 660, in __call__ if isinstance(value, (int, long)) or value.isdigit(): AttributeError: 'NoneType' object has no attribute 'isdigit' ## 'name' field here should throw error for not being in set defined by model- >>> new_record = db.datatable.validate_and_insert(title='test title', name='test name', dtype='1', finished=False, the_timestamp=datetime.utcnow(), alive=True, comments='this is a test') Traceback (most recent call last): File "<console>", line 1, in <module> File ".../gluon/packages/dal/pydal/objects.py", line 749, in validate_and_insert response, new_fields = self._validate_fields(fields) File ".../gluon/packages/dal/pydal/objects.py", line 741, in _validate_fields value, error = self[fieldname].validate(raw_value) File ".../gluon/packages/dal/pydal/objects.py", line 1634, in validate (value, error) = validator(value) File ".../gluon/validators.py", line 660, in __call__ if isinstance(value, (int, long)) or value.isdigit(): AttributeError: 'NoneType' object has no attribute 'isdigit' ## all fields- >>> new_record = db.datatable.validate_and_insert(title='test title', name='a', dtype='1', finished=False, the_timestamp=datetime.utcnow(), alive=True, comments='this is a test') Traceback (most recent call last): File "<console>", line 1, in <module> File ".../gluon/packages/dal/pydal/objects.py", line 749, in validate_and_insert response, new_fields = self._validate_fields(fields) File ".../gluon/packages/dal/pydal/objects.py", line 741, in _validate_fields value, error = self[fieldname].validate(raw_value) File ".../gluon/packages/dal/pydal/objects.py", line 1634, in validate (value, error) = validator(value) File ".../gluon/validators.py", line 660, in __call__ if isinstance(value, (int, long)) or value.isdigit(): AttributeError: 'NoneType' object has no attribute 'isdigit' Thanks again for your help.
