How to format Django settings file for flake8

Question

I'm a little obsessed with creating python code using flake8. However, I cannot find a good way to solve the E501 (the string is too long x> 79 characters) in the Django settings file.

At first it was like this (4xE501):

AUTH_PASSWORD_VALIDATORS = [
    {
        'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
    },
]

and then I came up with the following:

AUTH_PASSWORD_VALIDATORS = [{
    'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
    }, {
    'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
    }, {
    'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
    }, {
    'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
    },
]

But still 'NAME':django.contrib.auth.password_validation.UserAttributeSimilarityValidator',too long. Is there a way to format this or should I ignore this?

Answer 1

If you are obsessed with not getting this warning more than the actual appearance of your code, you can break the python code line (without breaking its continuity) by adding a character \at the time of interruption:

Examples:

# 1
from some_module import some_method, some_other_method, \
                        a_third_method

# 2
s = "A really very long string, which exist to mesh with your pep8" \
    " warning free obsession. Well, not anymore!!!"    

: \ , , , {}, [] or (), :

AUTH_PASSWORD_VALIDATORS = [{
    'NAME': 'django.contrib.auth.password_validation.'
            'UserAttributeSimilarityValidator'
    }, ...

, ...

, , :

# nopep8 

, pep8.

Answer 2

( PEP8):

[{"NAME": f"django.contrib.auth.password_validation.{name}"}
 for name in [
    "UserAttributeSimilarityValidator",
    "MinimumLengthValidator",
    "CommonPasswordValidator",
    "NumericPasswordValidator"]]

python 2 {}".format(name), f"".

| Django docs :

PEP 8 . 79 , , . 119 , GitHub.

Django ( flake8 PEP8). , , .flake8 setup.cfg :

[flake8]
max-line-length = 119
