django-audiofield

Django-audiofield is a Django application which allows audio file upload and conversion to mp3, wav and ogg format. It also makes it easy to play the audio files into your django application, for this we integrated a HTML5 and Flash audio player 'SoundManager2'

The goal of this project is to quickly manage audio files into your django project and make it easy for admins and users to listen to them.

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 = '<ul class="playlist"><li style="width:250px;">\
        <a href="%s">%s</a></li></ul>' % (file_url, os.path.basename(self.audio_file.name))
        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

If you are not using the installation script, please copy following template file to your template directory:

cp audiofield/templates/common_audiofield.html /path/to/your/templates/directory/

Add the following in your template files (like admin/change_form.html, admin/change_list.html etc. in which you are using audio field type):

{% block extrahead %}
{{ block.super }}
    {% include "common_audiofield.html" %}
{% endblock %}

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
