使用 factory_boy 和 faker 为 django 模型生成特定子网的 Ipv4 地址

Question

大家好！

下面是一个使用 faker 填充模型的脚本。 Faker 允许使用 'address_class' 参数。指定 address_class='a' 会缩小范围，但仅限于 10.0.0.0/8。如何进一步调整生成器，例如调整到 10.10.10.0/24?

import os
import django
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.local")
django.setup()
from workplace.models import IpAddress
import factory
import faker
from faker.providers import internet
faker = faker.Factory.create()


class IpAddressFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = IpAddress
        django_get_or_create = ('ip_address',)
    ip_address = faker.ipv4_private(address_class='a')


ip = IpAddressFactory()
print(ip)

Answer 1

ipv4_private 从 providers.internet

使用 class _IPv4Constants._private_networks

调整 class IPv4Constants 中的 _private_networks 就可以了

/lib/python3.7/site-packages/faker/providers/internet/init.py`

class _IPv4Constants:
    """
    IPv4 network constants used to group networks into different categories.
    Structure derived from `ipaddress._IPv4Constants`.

    Excluded network list is updated to comply with current IANA list of
    private and reserved networks.
    """
    # Three common private networks from class A, B and CIDR
    # to generate private addresses from.
    _private_networks = [
        # ip_network('10.0.0.0/8'),
        # ip_network('172.16.0.0/12'),
        # ip_network('192.168.0.0/16'),
        ip_network('10.10.10.0/24'),

    ]
