Django UnicodeEncodeError on QuerySet extra to PostgreSQL if started from shell

Hello all I'm using Django 1.2.5 with Python 2.6 on two machines: Ubuntu 11.04 and Debian Lenny. First one is my local dev and second is remote server. I'm using django-fts and postgresql (database is remote and unique for both installations) to make full text search queries. The intriguing thing is I can do fts query with russian symbols in it on local machine all right. On remote server it gives me UnicodeEncodeError while evaluating my extra.

In django-fts postgre backend I find this code:

    ts_query = "plainto_tsquery('%s','%s')" % (self.language, unicode(query).replace("'", "''"))
    where = '%s @@ %s' % (qn(self.vector_field.column), ts_query)
    select = {}
    order = []
    if rank_field is not None:
        select[rank_field] = 'ts_rank(%s.%s, %s, %d)' % (qn(self.model._meta.db_table), qn(self.vector_field.column), ts_query, rank_normalization)
        order = ['-%s' % rank_field]
    return qs.extra(select=select, where=[where], order_by=order)`

where query contains u'\u0430' or u"а" (cyrillic) so it encoded in utf-8 all right so far.

Error appears in django/db/models/sql/compiler.py on line 489 while trying to assemble a query from extras: result.append('(%s)' % str(col))

So, I tried all of coding/decoding stuff. LANG variable is "ru_RU.UTF-8" on both computers and in settings.py as DEFAULT_CHARSET. Have no more ideas. Any help?

UPDATE: I've just found out that my application executes the same way on both computers. The difference is between execution from shell (python manage.py runserver localhost:8000) and debug-mode start from eclipse's pyde开发者_如何学Cv environment. So, can some one tell me if there's difference between manual start and pydev debug start concerning my encoding problems?

TIA. Petr

add a u'' to all the string in your example.
like u'ts_rank(%s.%s, %s, %d)' % (...)
and also interpolating variables with % without database escape is bad.
