# 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 = '<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

touch /var/log/audio-field.log
