Hi everyone! First time posting to this group!
I have a model Class where each row has a unique alphanumeric ID string
like 'EX39H'.
This is the function I use to generate the code.
def gen_class_code():
import string
import random
size = 5
max_size = 16
attempts = 1000
chars = string.ascii_uppercase + string.digits
# lets try <attempts> times to generate unique id, else increase code
length
res = ""
while (size <= max_size):
for i in range(attempts):
temp = ''.join(random.choice(chars) for i in range(size))
if not Class.objects.filter(code=temp).exists():
res = temp
break
if res : break
return res
How much would you set the attempts variable to and why?
Thanks in advance
Anton
