|Python| |Django| |License| |PyPIv| |PyPIs| |Build Status| |Coverage Status| |Downloads| ConstrainedFileField for Django =============================== This Django app adds a new field type, ``ConstrainedFileField``, that has the capability of checking the file size and type. Also provides a javascript checker for the form field. Features -------- - File size limitation - File type limitation - Javascript file size checker Requirements ------------ - `Python <https://www.python.org/>`__ >= 3.5 - `Django <https://www.djangoproject.com/>`__>= 2.2.28 - ``python-magic`` >= 0.4.2 *iff* you want to check the file type Installation ------------ Using PyPI ~~~~~~~~~~ 1. Run - ``pip install django-constrainedfilefield``, or - ``pip install django-constrainedfilefield[filetype]`` to ensure ``python-magic`` is installed. 2. For windows, you must download the dll files and .magic file at https://github.com/pidydx/libmagicwin64 (32-bit version: http://gnuwin32.sourceforge.net/packages/file.htm)), add them to C:\Windows\System32 (or to a folder in your PATH), and set MAGIC_FILE_PATH=“…” to the path of your .magic file in your settings.py. For more information about the files to download, go to: https://github.com/ahupp/python-magic/blob/43df08c5ed63d7aad839695f311ca1be2eeb1ecb/README.md#dependencies Using the source code ~~~~~~~~~~~~~~~~~~~~~ 1. Make sure `Pandoc <http://pandoc.org/index.html>`__ is installed 2. Run ``./pypi_packager.sh`` 3. Run ``pip install dist/django_constrainedfilefield-x.y.z-[...].wheel``, where ``x.y.z`` must be replaced by the actual version number and ``[...]`` depends on your packaging configuration 4. For windows, you must download the dll files and .magic file at https://github.com/pidydx/libmagicwin64 (32-bit version: http://gnuwin32.sourceforge.net/packages/file.htm)), add them to C:\Windows\System32 (or to a folder in your PATH), and set MAGIC_FILE_PATH=“…” to the path of your .magic file in your settings.py. For more information about the files to download, go to: https://github.com/ahupp/python-magic/blob/43df08c5ed63d7aad839695f311ca1be2eeb1ecb/README.md#dependencies Usage ----- Validate single file ~~~~~~~~~~~~~~~~~~~~ The field can be used in forms or model forms like a normal ``FileField``. If a user tries to upload a file which is too large or without a valid type, a form validation error will occur. Note that the validation does not occur on the field itself (on ``save()``), but when validated through a form. Creating form from model ^^^^^^^^^^^^^^^^^^^^^^^^ Create a model and add a field of type ``ConstrainedFileField``. You can add a maximum size in bytes and a list of valid mime types that will be allowed. The list of all mime types is available here: http://www.iana.org/assignments/media-types/index.html. Setting none of the above, it behaves like a regular ``FileField``. :: from django.db import models from constrainedfilefield.fields import ConstrainedFileField class TestModel(models.Model): the_file = ConstrainedFileField( null=True, blank=True, upload_to='testfile', content_types=['image/png'], max_upload_size=10240 ) :: from django import forms from myproject.models import TestModel class TestModelForm(forms.ModelForm): class Meta: model = TestModel fields = ['the_file'] Building a form ^^^^^^^^^^^^^^^ :: from django import forms from constrainedfilefield.fields import ConstrainedFileField class TestNoModelForm(forms.Form): the_file = ConstrainedFileField( null=True, blank=True, upload_to='testfile', content_types=['image/png'], max_upload_size=10240 ).formfield() Javascript file size validation ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Additionally, to prevent user uploading too large files, a javascript checker can be set to the form field. In order to achieve that, you need to 1. Add ``constrainedfilefield`` to the ``INSTALLED_APPS``. This will load the javascripts from the static files. 2. Activate this feature by setting ``js_checker=True`` when instantiating the ``ConstrainedFileField``. 3. Include the javascript in the template where the form field is used .. code:: django {% load static %} <script src="{% static 'constrainedfilefield/js/file_checker.js' %}"></script> Validate single image ~~~~~~~~~~~~~~~~~~~~~ Same as above, using ``ConstrainedImageFileField`` instead. The ``ConstrainedImageField`` offers additional constraints: \* ``[min|max]_upload_[width|height]`` to define min/max dimensions, respectively width and height. Note on DOS attacks ------------------- Important note: the check of the file size is made by Django once the whole file has been uploaded to the server and stored in a temp directory (or in memory if the file is small). Thus, this is useful to guarantee the quota of the users, for example, but will not stop an attacking user that wants to block the server by sending huge files (e. g. of several Gb). To avoid this, you need to configure your front end to limit the size of uploaded files. How to do it depends on the software you are using. For example, if you use apache, you should use `LimitRequestBody <http://httpd.apache.org/docs/2.2/mod/core.html#limitrequestbody>`__ directive. This is a complementary measure, because you’ll usually want normal users that exceed the size by a reasonable amount to get a friendly form validation message, while attacking users will see how their connection is abruptly cut before the file finishes uploading. So the recommended setting is to give ``max_upload_size`` a small value (e.g. 5Mb) and ``LimitRequestBody`` a higher one (e.g. 100Mb).
