AttributeError: module 'string' has no attribute 'letters'

[beeekind]

This error is raised when the following code is called in a Django test case:

from django_faker import Faker

populator = Faker.getPopulator()
populator.addEntity(User, 2)
# Task contains a foreign key to a User object
populator.addEntity(Task, 5)
models = populator.execute()

Relevant stacktrace

If the test is run 5 times it will only error 3 or 4 times it is run - which makes it even more confusing. Any idea what is going on here? Thanks.

hey I'm not dealing with django yet but i had the same issue today when i was working with old project
module string has changes in python3
in python 2 'string.letters' was working fine
but in python 3 you need to add 'string.ascii_letters'
in your case probably you need to edit File "/usr/local/lib/python3.6/site-packages/faker/providers/init.py", line 35
in return random.choice( string.letters )
to
return random.choice( string.ascii_letters )

I had the same error in Flask . i just tried "string.ascii_letters" instead of "string.letters"
