Django TarView
==============

A base view to tar and stream several files.

Installation
------------

pip install django-tarview

Usage and examples
------------------

To create a tar download view:

* Extend BaseTarView
* implement `get_files`
* That's it

The `get_files` method must return a list (or iterator) of file-like objects.

Example with a ContentFile:


```
from tarview.views import BaseTarView

class JustTextFilesView(BaseTarView):
"""
Generate a tar with 10 files 'fileX.txt' with a simple text,
using Djangos ContentFile
"""
def get_files(self):
for i in range(0,10):
file_like = ContentFile(b("This is file %d." % i), name="file%d.txt" % i)
yield file_like
```

Or pull them from a database like this:

```python
from tarview.views import BaseTarView

from reviews import Review

class CommentsArchiveView(BaseTarView):
"""Download at once all comments for a review."""

def get_files(self):
document_key = self.kwargs.get('document_key')
reviews = Review.objects \
.filter(document__document_key=document_key) \
.exclude(comments__isnull=True)

return [review.comments.file for review in reviews if review.comments.name]
```

View configuration
------------------

By default, the downloaded file is named `download.tar` you can set a custom name
by setting the `tarfile_name` parameter.

```python

class TarView(BaseTarView):
tarfile_name = 'something.tar'
```

Testing
-------

Django TarView uses [tox, the testing automation tool](https://tox.readthedocs.org/en/latest/),
