let say i have a code:
*models/db_wizard_1_bank.py*
db.define_table('bank',
Field('name'),
Field('website'),
format = '%(name)s')
*controllers/install.py*
def index():
if db(db.auth_permission).isempty() and db(db.auth_membership).isempty():
# create index : auth_user
db.executesql('CREATE INDEX idx_auth_user ON auth_user (id, first_name,
last_name, email, username);')
# insert : bank
db.bank.bulk_insert([
{'name1' : 'bank0', 'website' : 'http://www.bank0.com'},
{'name' : 'bank1', 'website' : 'http://www.bank1.com'}, ] )
session.flash = T('Installation Done')
redirect(URL('default', 'index') )
as you can see, i made a mistake during insert to table bank field name1
(incorrect), should be field name in table bank, but the traceback error
said is different.
what i got in traceback error :

again, same code with different structure order (insert first then create
index) in install.py
*controllers/install.py*
def index():
if db(db.auth_permission).isempty() and db(db.auth_membership).isempty():
# insert : bank
db.bank.bulk_insert([
{'name1' : 'bank0', 'website' : 'http://www.bank0.com'},
{'name' : 'bank1', 'website' : 'http://www.bank1.com'}, ] )
# create index : auth_user
db.executesql('CREATE INDEX idx_auth_user ON auth_user (id, first_name,
last_name, email, username);')
session.flash = T('Installation Done')
redirect(URL('default', 'index') )
as you can see, i made a mistake during insert to table bank field name1
(incorrect), should be field name in table bank, but the traceback error
said is straight to the point to show where is my mistake.
what i got in traceback error :

<type 'exceptions.SyntaxError'>(Field name1 does not belong to the table)
the solution is either i comment the create index part or change the order
to get the clear traceback error, my question is it normal?
thanks and best regards,
