tried to build from scratch with minimal code for test before insert
callback problem :
*1. create new web2py app*
*2. models/db_test.py*
def before_insert_test(f):
f['field1'] = 'field1'
db.define_table('table0',
Field('field0', notnull = True, required = True),
Field('field1', notnull = True, required = True) )
db.table0._before_insert.append(before_insert_test)
*3. controllers/install.py*
def index():
db.table0.insert(field0 = 'field0')
*4. error result*
Traceback (most recent call last):
File "/Users/MacBookPro/site/web2py/gluon/restricted.py", line 219, in
restricted
exec(ccode, environment)

"/Users/MacBookPro/site/web2py/applications/test/controllers/install.py",

line 4, in index
db.table0.insert(field0 = 'field0')

line 731, in insert
row = self._fields_and_values_for_insert(fields)
File "/Users/MacBookPro/site/web2py/gluon/packages/dal/pydal/objects.py",
line 709, in _fields_and_values_for_insert
'Table: missing required field: %s' % name)
RuntimeError: Table: missing required field: field1
*5. temporary solution*
i know there are 2 temporary solutions for this:
1. remove notnull=True and required=True
2. set the value for required value, e.g. field1 during insert
*6. question*
the same code work in previous stable version (2.14.6-stable), is it a
problem or normal in web2py latest version?
thanks and best regards,
stifan
