如何在heroku上设置django-compressor,离线压缩到S3

Question

我按照在SO和不同博客中找到的每个QA建议,在我的开发机器上一切正常,在heroku上没有任何作用.

这是我的设置:

DEFAULT_FILE_STORAGE = 'arena.utils.MediaRootS3BotoStorage' # media files
# storage

AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID')
AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY')
AWS_STORAGE_BUCKET_NAME = os.environ.get('AWS_STORAGE_BUCKET_NAME')
AWS_PRELOAD_METADATA = True # necessary to fix manage.py collectstatic command to only upload changed files instead of all files

S3_URL = 'https://%s.s3.amazonaws.com' % AWS_STORAGE_BUCKET_NAME
MEDIA_URL = S3_URL + '/media/'

STATIC_URL = S3_URL + '/static/'

ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/'


COMPRESS_URL = STATIC_URL
COMPRESS_OFFLINE = True
COMPRESS_STORAGE = 'utils.CachedS3BotoStorage'
STATICFILES_STORAGE = COMPRESS_STORAGE

当我运行collectstatic/compress时,一切正常,我看到文件被收集到S3并放入适当的位置.我看到了清单文件.

加载任何带有压缩标签的页面,显示错误再次OfflineGenerationError: You have offline compression enabled but key "d2a53169c44dec41ce3ee7da19b2b9d4" is missing from offline manifest.运行python manage.py compress不会解决任何问题.当我检查清单文件时,它确实找不到的密钥.

这里出了什么问题？

问题我已经检查过了:

如何使用亚马逊的S3配置django-compressor和django-staticfiles？

带有S3 URL Heroku的Django Compressor

使用远程存储配置django-compressor(django-storage - amazon s3)

Answer 1

在我这边，我有非常相似的配置，并且我已经成功使用压缩器超过 2 年了。

设置.py

COMPRESS_STORAGE = 'MyAwesomeApp.app.CachedS3BotoStorage.CachedS3BotoStorage'

AWS_ACCESS_KEY_ID = '#######'
AWS_SECRET_ACCESS_KEY = '########################+#########+BqoQ'
AWS_STORAGE_BUCKET_NAME = 'myAmazonS3cdn.myawesomewebsite.com'
AWS_S3_SECURE_URLS = False
AWS_QUERYSTRING_AUTH = False

COMPRESS_ROOT = 'MyAwesomeApp/static'
STATIC_ROOT = 'MyAwesomeApp/static/javascript'
COMPRESS_OUTPUT_DIR = 'compressed'
STATICFILES_STORAGE = COMPRESS_STORAGE

STATIC_URL = "http://myAmazonS3cdn.myawesomewebsite.com/"
COMPRESS_URL = STATIC_URL
COMPRESS_ENABLED = True

缓存S3BotoStorage.py

from django.core.files.storage import get_storage_class
from storages.backends.s3boto import S3BotoStorage

from django.core.files.base import File

class CachedS3BotoStorage(S3BotoStorage):
    """
    S3 storage backend that saves the files locally, too.
    """
    def __init__(self, *args, **kwargs):
        super(CachedS3BotoStorage, self).__init__(*args, **kwargs)
        self.local_storage = get_storage_class("compressor.storage.CompressorFileStorage")()

    def save(self, name, content):
        name = super(CachedS3BotoStorage, self).save(name, content)
        self.local_storage._save(name, content)
        return name

我正在本地运行python managep.py compress，并在静态文件目录中生成清单。Heroku 只处理 collecstatic 并将最新的清单版本传递到我的 CDN。
