Usage examples

With Faker

One way

from faker import Faker
from faker_file.providers.txt_file import TxtFileProvider

FAKER = Faker()

file = TxtFileProvider(FAKER).txt_file()

If you just need bytes back (instead of creating the file), provide the raw=True argument (works with all provider classes and inner functions):

raw = TxtFileProvider(FAKER).txt_file(raw=True)

Or another

from faker import Faker
from faker_file.providers.txt_file import TxtFileProvider

FAKER = Faker()
FAKER.add_provider(TxtFileProvider)

file = FAKER.txt_file()

If you just need bytes back:

raw = FAKER.txt_file(raw=True)

With factory_boy

upload/models.py

from django.db import models

class Upload(models.Model):

    # ...
    file = models.FileField()

upload/factories.py

Note, that when using faker-file with Django and native file system storages, you need to pass your MEDIA_ROOT setting as root_path value to the chosen file storage as show below.

import factory
from django.conf import settings
from factory import Faker
from factory.django import DjangoModelFactory
from faker_file.providers.docx_file import DocxFileProvider
from faker_file.storages.filesystem import FileSystemStorage

from upload.models import Upload

FS_STORAGE = FileSystemStorage(
    root_path=settings.MEDIA_ROOT,
    rel_path="tmp"
)
factory.Faker.add_provider(DocxFileProvider)

class UploadFactory(DjangoModelFactory):

    # ...
    file = Faker("docx_file", storage=FS_STORAGE)

    class Meta:
        model = Upload

File storages

All file operations are delegated to a separate abstraction layer of storages.

The following storages are implemented:

• FileSystemStorage: Does not have additional requirements.

• PathyFileSystemStorage: Requires pathy.

• AzureCloudStorage: Requires pathy and Azure related dependencies.

• GoogleCloudStorage: Requires pathy and Google Cloud related dependencies.

• AWSS3Storage: Requires pathy and AWS S3 related dependencies.

Usage example with storages

FileSystemStorage example

Native file system storage. Does not have dependencies.

import tempfile
from faker import Faker
from faker_file.providers.txt_file import TxtFileProvider
from faker_file.storages.filesystem import FileSystemStorage

FS_STORAGE = FileSystemStorage(
    root_path=tempfile.gettempdir(),  # Use settings.MEDIA_ROOT for Django
    rel_path="tmp",
)

FAKER = Faker()

file = TxtFileProvider(FAKER).txt_file(storage=FS_STORAGE)

FS_STORAGE.exists(file)

PathyFileSystemStorage example

Native file system storage. Requires pathy.

import tempfile
from pathy import use_fs
from faker import Faker
from faker_file.providers.txt_file import TxtFileProvider
from faker_file.storages.cloud import PathyFileSystemStorage

use_fs(tempfile.gettempdir())
PATHY_FS_STORAGE = PathyFileSystemStorage(
    bucket_name="bucket_name",
    root_path="tmp"
    rel_path="sub-tmp",
)

FAKER = Faker()

file = TxtFileProvider(FAKER).txt_file(storage=PATHY_FS_STORAGE)

PATHY_FS_STORAGE.exists(file)

AWSS3Storage example

AWS S3 storage. Requires pathy and boto3.

from faker import Faker
from faker_file.providers.txt_file import TxtFileProvider
from faker_file.storages.aws_s3 import AWSS3Storage

S3_STORAGE = AWSS3Storage(
    bucket_name="bucket_name",
    root_path="tmp",  # Optional
    rel_path="sub-tmp",  # Optional
    # Credentials are optional too. If your AWS credentials are properly
    # set in the ~/.aws/credentials, you don't need to send them
    # explicitly.
    credentials={
        "key_id": "YOUR KEY ID",
        "key_secret": "YOUR KEY SECRET"
    },
)

FAKER = Faker()

file = TxtFileProvider(FAKER).txt_file(storage=S3_STORAGE)

S3_STORAGE.exists(file)

Testing

Simply type:

pytest -vrx

Or use tox:

tox

Or use tox to check specific env:

tox -e py310-django41
