Secure file field, which allows you to restrict uploaded file extensions.

It may be useful for user-uploaded files (attachments).

This package adds model and forms field. What this fields does:

 * restricts allowed file extensions (for example: only *.pdf files)

 * checks file extensions is correct for sent content-type

 * checks sent content type is correct for file content (detects by `libmagic`)

 * checks uploaded file with anti-virus software

Installation

------------

The package can be installed using:

.. code-block::

   pip install django-safe-filefield

Add the following settings:

.. code-block:: python

   INSTALLED_APPS += [

       'safe_filefield',

   ]

**django-safe-filefield** requires `libmagic` to be installed.

Usage

-----

Simply add field to your model:

.. code-block:: python

   from safe_filefield.models import SafeFileField

   class MyModel(models.Model):

       attachment = SafeFileField(

           allowed_extensions=('xls', 'xlsx', 'csv')

       )

Or directly to your form:

.. code-block:: python

   from safe_filefield.forms import SafeFileField

   class MyForm(forms.Form):

       attachment = SafeFileField(

           allowed_extensions=('xls', 'xlsx', 'csv')

       )

Content type checking

+++++++++++++++++++++

To check actual file content type, use `check_content_type` argument. This

will prevent attacker from uploading malicious file just by changing its

extension.

.. code-block:: python

   class MyForm(forms.Form):

       attachment = SafeFileField(

           check_content_type=True

       )

ClamAV support

++++++++++++++

.. note:: To use this functionality you should have `clamd` daemon.

This package has ability to check uploaded file with ClamAV antivirus.

To use anti-virus protection simply enable it in your form or model definition:

.. code-block:: python

   from safe_filefield.forms import SafeFileField

   class MyForm(forms.Form):

       attachment = SafeFileField(

           scan_viruses=True,

       )

You can configure some ClamAV settings:

.. code-block:: python

   CLAMAV_SOCKET = 'unix://tmp/clamav.sock'  # or tcp://127.0.0.1:3310

   CLAMAV_TIMEOUT = 30  # 30 seconds timeout, None by default which means infinite
