Actually I think it's easier ...
conn = sql.connectionForURI(uri)
if conn.dbName == 'sqlite':
from sqlobject.sqlite.sqliteconnection import SQLiteConnection
conn = SQLiteConnection(
filename=conn.filename,
name=conn.name, debug=conn.debug, debugOutput=conn.debugOutput,
cache=conn.cache, style=conn.style, autoCommit=conn.autoCommit,
debugThreading=conn.debugThreading, registry=conn.registry,
factory=CustomSQLiteConnectionFactory
)
and
def CustomSQLiteConnectionFactory(sqlite):
class MyConnection(sqlite.Connection):
def __init__(self, *args, **kwargs):
super(MyConnection, self).__init__(*args, **kwargs)
self.create_collation("debian", self.collate_debian)
def collate_debian(obj,string1, string2):
return Compare(string1, string2)
return MyConnection
where obj is:
['DataError', 'DatabaseError', 'Error', 'IntegrityError', 'InterfaceError',
'InternalError', 'NotSupportedError', 'OperationalError', 'ProgrammingError',
'Warning', '__call__', '__class__', '__delattr__', '__dict__', '__doc__',
'__getattribute__', '__hash__', '__init__', '__module__', '__new__',
'__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__str__',
'__weakref__', 'close', 'collate_debian', 'commit', 'create_aggregate',
'create_collation', 'create_function', 'cursor', 'execute', 'executemany',
'executescript', 'interrupt', 'isolation_level', 'rollback', 'row_factory',
'set_authorizer', 'text_factory', 'total_changes']
but I don't kind of understand what I should do with it ...
anyway almost there ...
:)
