Came up with a workaround.
def store_file(file, filename=None, path=None):
try:
client_id = int(request.args[2])
client_dir = db(db.client.id == client_id).select(db.client.
client_dir_name).first().client_dir_name
except:
client_dir = 'Default'
path = "applications/init/uploads/%s" % (client_dir)
if not os.path.exists(path):
os.makedirs(path)
pathfilename = os.path.join(path, filename)
dest_file = open(pathfilename, 'wb')
try:
shutil.copyfileobj(file, dest_file)
finally:
dest_file.close()
return filename
I'm using a smartgrid so the client id is passed as an argument when I
client on the files link.
