django-audiofield 0.10.0

Django声场

django audiofield是一个简单的应用程序，允许音频文件上传、管理和转换为不同的音频格式（mp3、wav&ogg），这也使得将音频文件轻松播放到django应用程序中。

我们正在使用html5和flash音频播放器SoundManager2

安装

安装Django AudioField:

python setup.py install

apt-get -y install libsox-fmt-mp3 libsox-fmt-all mpg321 dir2ogg libav-tools

yum -y install python-setuptools libsox-fmt-mp3 libsox-fmt-all mpg321 dir2ogg

git clone git://git.libav.org/libav.git
cd libav
sudo ./configure --disable-yasm
sudo make
sudo make install

设置

在settings.py文件中：

# Set Following variable
MEDIA_ROOT = ''
MEDIA_URL = ''

In MIDDLEWARE_CLASSES add 'audiofield.middleware.threadlocals.ThreadLocals'

In INSTALLED_APPS add 'audiofield'

# Frontend widget values
# 0-Keep original, 1-Mono, 2-Stereo
CHANNEL_TYPE_VALUE = 0

# 0-Keep original, 8000-8000Hz, 16000-16000Hz, 22050-22050Hz,
# 44100-44100Hz, 48000-48000Hz, 96000-96000Hz
FREQ_TYPE_VALUE = 8000

# 0-Keep original, 1-Convert to MP3, 2-Convert to WAV, 3-Convert to OGG
CONVERT_TYPE_VALUE = 0

用法

在models.py文件中添加以下行：

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')

在admin.py中添加以下行：

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

然后执行以下命令创建表并收集静态文件：

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

创建audiofield.log文件：

touch /var/log/audio-field.log
