Subject: [dabo-users] dDataSet and encoding
How can I set the encoding on the datasets? I use a lot of datasets
individually (without bizobjs etc) in my application, and want them in a
different encoding. Can you put in an Encoding parameter on the datasets like
this:
>>> from dabo.db import dDataSet
>>> ds = dDataSet(({"lala":"æøå"},))
>>> ds
({'lala': '\xe6\xf8\xe5'},)
>>> ds.execute("select * from dataset")
Traceback (most recent call last):
File "<input>", line 1, in ?
File "c:\python24\lib\site-packages\Dabo-0.7a-py2.4.egg\dabo\db\dDataSet.py",
line 357, in execute
self._cursor.execute(sqlExpr, params)
OperationalError: Could not decode to UTF-8 column <unknown column name> with
text æøå
A possible solution (it's what I use with regular sqlite, and it is working
well):
>>> ds._connection.text_factory = lambda s: unicode(s, "latin1", "replace")
>>> ds.execute("select * from dataset")
({'lala': u'\xe6\xf8\xe5'},)
>>> print ds[0]["lala"]
æøå
