Django-Audiofield

Django-Audiofield is a simple app that allows Audio files upload, management and conversion to different audio format (mp3, wav & ogg), which also makes it easy to play audio files into your Django application.

We are using the HTML5 and Flash audio player SoundManager2

Usage

Add the following lines in your models.py file:

from django.conf import settings
from audiofield.fields import AudioField
import os.path

# Add the audio field to your model
audio_file = AudioField(upload_to='your/upload/dir', blank=True,
                        ext_whitelist=(".mp3", ".wav", ".ogg"),
                        help_text=("Allowed type - .mp3, .wav, .ogg"))

# Add this method to your model
def audio_file_player(self):
    """audio player tag for admin"""
    if self.audio_file:
        file_url = settings.MEDIA_URL + str(self.audio_file)
        player_string = '<audio src="%s" controls>Your browser does not support the audio element.</audio>' % (file_url)
        return player_string

audio_file_player.allow_tags = True
audio_file_player.short_description = ('Audio file player')

Add the following lines in your admin.py:

from your_app.models import your_model_name

# add 'audio_file_player' tag to your admin view
list_display = (..., 'audio_file_player', ...)
actions = ['custom_delete_selected']

def custom_delete_selected(self, request, queryset):
    #custom delete code
    n = queryset.count()
    for i in queryset:
        if i.audio_file:
            if os.path.exists(i.audio_file.path):
                os.remove(i.audio_file.path)
        i.delete()
    self.message_user(request, ("Successfully deleted %d audio files.") % n)
custom_delete_selected.short_description = "Delete selected items"

def get_actions(self, request):
    actions = super(AudioFileAdmin, self).get_actions(request)
    del actions['delete_selected']
    return actions

Then perform following commands to create the table and collect the static files:

./manage.py syncdb
./manage.py collectstatic

Create audiofield.log file:

touch /var/log/audio-field.log

TODO

• Use pydub (http://pydub.com) to lift the audio conversion away from django-audiofield
• integrate with django-storage (http://django-storages.readthedocs.org/)
• support more formats
