Ok, forget about it Massimo. I found why I get duplicated field name error.
Multiples tables in one form works, but I have a bizzard thing, see by your
self :
db.define_table('ref_fnaregistry',
Field('fnaregistry_id','id'),
Field('num_part1','string',
length=20,
notnull=True,
requires=[IS_NOT_EMPTY(error_message=T('field can\'t be empty'))],
required=True
),
Field('num_part2','string',
length=20,
notnull=True,
requires=[IS_NOT_EMPTY(error_message=T('field can\'t be empty'))],
required=True
),
Field('num_part3','string',
length=20,
notnull=True,
requires=[IS_NOT_EMPTY(error_message=T('field can\'t be empty'))],
required=True
),
#migrate=False,
sequence_name='ref_fnaregistry_fnaregistry_id_seq',
format=lambda row: '%s-%s-%s'\
%(row.num_part1.rstrip(),row.num_part2.rstrip(),row.num_part3.rstrip()))
# ref_vregistry
db.define_table('ref_vregistry',
Field('vregistry_id','id'),
Field('vol_num','integer',
notnull=True,
requires=[IS_NOT_EMPTY(error_message=T('field can\'t be empty'))],
required=True
),
Field('vol_fnaregistry_id',db.ref_fnaregistry),
#migrate=False,
sequence_name='ref_vregistry_vregistry_id_seq',
format='%(vol_num)s')
db.ref_vregistry.vol_fnaregistry_id.requires =
IS_IN_DB(db,'ref_fnaregistry.fnaregistry_id',db.ref_fnaregistry._format)
# ref_tregistry
db.define_table('ref_tregistry',
Field('tregistry_id','id'),
Field('tome_num','integer',
notnull=True,
requires=[IS_NOT_EMPTY(error_message=T('field can\'t be empty'))],
required=True
),
Field('vregistry_id',db.ref_vregistry),
Field('tom_fnaregistry_id',db.ref_fnaregistry),
#migrate=False,
sequence_name='ref_tregistry_tregistry_id_seq',
format='%(tome_num)s')
db.ref_tregistry.vregistry_id.requires =\
IS_NULL_OR(IS_IN_DB(db,'ref_tregistry.vregistry_id',db.ref_tregistry._format))
db.ref_tregistry.tom_fnaregistry_id.requires =\
IS_NULL_OR(IS_IN_DB(db,'ref_fnaregistry.fnaregistry_id',db.ref_fnaregistry._format))
# ref_eregistry
db.define_table('ref_eregistry',
Field('eregistry_id','id'),
Field('exp_num','string',
length=255,
notnull=True,
requires=[IS_NOT_EMPTY(error_message=T('field can\'t be empty'))],
required=True
),
Field('tregistry_id',db.ref_tregistry),
#migrate=False,
sequence_name='ref_eregistry_eregistry_id_seq',
format='%(exp_num)s')
in ref_tregistry I can make relation with fnaregistry or vregistry... It was
causing the problem... I changed the name of the fnaregistry_id for
vol_fnaregistry_id and tom_fnaregistry_id that solve the duplicated field
name problem and I can load input with this modified controller from the
book :
def create_all_at_once():
db.ref_vregistry.vol_fnaregistry_id.readable=False
db.ref_vregistry.vol_fnaregistry_id.writable=False
db.ref_tregistry.vregistry_id.readable=False
db.ref_tregistry.vregistry_id.writable=False
db.ref_tregistry.tom_fnaregistry_id.readable=False
db.ref_tregistry.tom_fnaregistry_id.writable=False
db.ref_eregistry.tregistry_id.readable=False
db.ref_eregistry.tregistry_id.writable=False
form =
SQLFORM.factory(db.ref_fnaregistry,db.ref_vregistry,db.ref_tregistry,db.ref_eregistry)
if form.accepts(request.vars):
id =
db.ref_fnaregistry.insert(**db.ref_fnaregistry._filter_fields(form.vars))
form.vars.vol_fnaregistry_id=id
id =
db.ref_vregistry.insert(**db.ref_vregistry._filter_fields(form.vars))
form.vars.vregistry_id=id
id =
db.ref_tregistry.insert(**db.ref_tregistry._filter_fields(form.vars))
form.vars.tregistry_id=id
id =
db.ref_eregistry.insert(**db.ref_eregistry._filter_fields(form.vars))
response.flash='Thanks for filling the form'
return dict(form=form)
But I have to find a way to by pass the double relation problem I have... If
you have a idea... Maybe with list:reference multiple=True... But I don't
like this workaround it so much, since I have to use postgres function in my
SQL or relied entirely on web2py for query those tables... I prefer keep my
schema as simple as possible so it can be queried with basic SQL syntax
