Good to hear you're good to go. FWIW, I had little trouble transplanting
the appadmin example into my csv test program.
def getcsv():
import gluon.contenttype
response.headers['Content-Type'] = \
gluon.contenttype.contenttype('.csv')
query = db.uptable(id > 0)
response.headers['Content-disposition'] = 'attachment;
filename=%s_%s.csv'\
% tuple(request.vars.where.split('.')[:2])
return str(db(query, ignore_common_filters=True).select(db.uptable.id,db
.uptable.something))
(Yes, I really do have a field called "something" ... it is a test
program, after all)
theurl/getcsv?where=fiddle.x gets turned into fiddle_x.csv, in a minor
tweak of appadmin's attempt to get the table name.
