is there any difference to set variable on models or modules ?
*e.g.*
*models/db_connect.py*
db = DAL('sqlite://test.sqlite', pool_size = 1)
*modules/db_connect.py*
from gluon.dal import DAL
from gluon import current
db = DAL('sqlite://test.sqlite', pool_size = 1)
cache = current.cache
cache_time_expire = 10
cache_model = cache.ram # cache.ram, cache.disk, cache.memcache, cache.redis
cache_db = (cache_model, cache_time_expire)
*controllers/install.py*
import db_connect
def index():
db = db_connect.db
db_schema_1_address.define(db = db)
address_id_1 = db.address.insert(street = 'a', zip_code = '1', city =
'a', country = 'a')
*controllers/api.py*
import db_connect
#db = db_connect.db # not worked, must use from models/db.py
cache_db = db_connect.cache_db # this variable can be used from modules, no
error occured
db_schema_1_address.define(db = db)
def response_json_rows():
if not request.env.request_method == 'GET': raise HTTP(403)
table_name = request.args(0)
id = request.args(1)
if id.isdigit() and int(id) > 0:
query = (db[table_name]['id'] == id)
else:
query = (db[table_name]['id'] > 0)
rows = db(query).select(orderby = ~db[table_name]['id'],
cache = cache_db,
cacheable = True)
return response.json(rows)
Traceback (most recent call last):

line 581, in define_table
raise SyntaxError('table already defined: %s' % tablename)
SyntaxError: table already defined: address
any ideas ?
intention is to move define tables from models into modules and load it on
controller when it's required, with minimal effort
thx n best regards,
stifan
