+# Django-dbfilestorage
+
+
+[![CircleCI](https://circleci.com/gh/tyrelsouza/django-dbfilestorage.svg?style=svg)](https://circleci.com/gh/tyrelsouza/django-dbfilestorage)
+
+Custom file storage for Django that stores file data and content type in the database.
+Easy to use for testing when you don't care about a filename, and just want to test file data.
+
+Intended to be used in tests, never in production.
+
+## INSTALLATION
+
+In your project's `settings.py` file, add `'dbfilestorage'` to your `INSTALLED_APPS`:
+
+```python
+INSTALLED_APPS = (
+    ...
+    'dbfilestorage'
+)
+```
+
+Next, if you want to set this globally, set the setting:
+
+```python
+DEFAULT_FILE_STORAGE='dbfilestorage.storage.DBFileStorage'
+```
+
+Or you can set it individually on a field: [Django Docs](https://docs.djangoproject.com/en/1.10/ref/models/fields/#django.db.models.FileField.storage)
+
+```python
+from dbfilestorage.storage import DBFileStorage
+
+class SomeClass(models.Model):
+    file = models.FileField(upload_to=u'anywhere',
+        storage=DBFileStorage())
+```
+
+
+## TODO
+
+- More Tests
+- Test that this works on a fake model, not just the storage file.
+- Different django and different python versions.
+- Store original filename in a field, maybe?
+- Use original filename instead, so it honors the "upload_to" parameter.
+
+
+## CHANGELOG
+
+- 2016-12-08 [Tyrel Souza] Add more documentation.
+- 2016-12-07 [Tyrel Souza] Update Readme, move to github, gitlab wasn't functioning properly.
+- 2016-12-07 [Tyrel Souza] Initial commits and basic project setup

+Usage
+=====
+
+Backstory
+---------
+
+The use case for this may be very small. At my company for our project we have
+a giant test fixture, and we test file upload and creation. At the inception of
+this module, I was working on changing our backend system to support Amazon S3
+filestorage. I was getting frustrated with testing the assumption that a file
+would exist on the hard drive, and not "somewhere else" so I started this module.
+
+At first, I was going to use the BLOB field, but the way that we dump and load
+our test fixtures didn't dump BLOBs by default.
+
+Thus, the current implementation was born.
+
+
+On to the Usage!
+----------------
+
+The normal usage for this is almost exactly the same for local file storage.
+The user will upload a file the exact same way, and except for the url being an
+md5 string, everything works exactly the same.
+
+Saving file
+~~~~~~~~~~~
+
+The save method does most of the 'magic'. It stores the contents of the file as
+a base64 string.  It then takes the filename, and tries to get the mimetype from
+that (for rendering purposes). Then it takes the md5 of the read file and uses
+that as the "unique" key to access the file. Then it checks if the file exists
+and if it doesn't, it will create the entry in the database.
+
+Example from Tests:
+
+.. code:: python
+
+    DBFileStorage.save("kris.jpg", file_object)
+
+There will then be an entry in the database `50f3bfa6b91668789acab5f0a733fb3a`
+that has the content of the `kris.jpg` file in it, with the content_type of
+`image/jpeg`.
+
+Opening file
+~~~~~~~~~~~~
+
+This file will then be accessible by the model field's `.open()` as normal.
+The `.open()` returns a ContentFile of the base64 decoded data, so it should
+work everywhere that a normal file would.
+
+Viewing file with browser ( .url() )
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+I've provided a `dbstorage_file` view that will render the file.
+
+It gets the file object from the database referenced by the md5 (the
+filefield.url() will provide this) automatically. It then returns a
+HttpResponse of the decoded file and content type. Very straightforward.
+
+Other operations
+~~~~~~~~~~~~~~~~
+
+Everything else, such as `.path()`, `.delete()`, `.size()`, `.exists()` are
+exactly the same, in usage as normal.
