I want to generate automatic random numbers in a blank field while saving it in django.
EDIT
The random numbers must be unique.
EDIT: Changed solution to make random number unique and to use Django's make_random_password
function. Note the below assumes you are storing the random number in a field called
temp_password in a model UserProfile that is an extension of the User model.
random_number = User.objects.make_random_password(length=10, allowed_chars='123456789')
while User.objects.filter(userprofile__temp_password=random_number):
random_number = User.objects.make_random_password(length=10, allowed_chars='123456789')
Also note that you can store the random code as a combination of letters and numbers as well. The
default value for allowed_chars is a string of letters and numbers minus a few that tend to cause
confusion among users (1, l, etc.)
More about Django's make_random_password function: https://docs.djangoproject.com/en/dev/topics/auth/#manager-functions
OLD:
import random
n = random.randint(a,b) # returns a random integer
in the example above a <= n <= b
