Curious, there is something wrong happening in Pylons/Paste.
I suppose what you reported is the body of your controller, have you tried
changing it to return the response body instead of the response object
itself?
Like:
from tg import response
class RootController(TGController):
@expose()
def mymethod(self):
response.content_type = 'text/csv'
response.headers['Content-Disposition'] =
'attachment;filename=%s.csv' % file_name
listWriter = csv.writer(open(title+'.csv', 'wb'),
delimiter=',', quotechar='|',
quoting=csv.QUOTE_MINIMAL)
listWriter.writerow(['foo', 'bar'])
content = ''
with open (title+'.csv', "r") as myfile:
content=myfile.read().replace('\n', '')
return content
PS: instead of writing on a file to read it back, you probably want to use
StringIO.getvalue()
