如何使用Amazon S3来配置django-compression和django-staticfiles？ [英] How to configure django-compressor and django-staticfiles with Amazon's S3?

问题描述

我正在尝试设置 django-compression 和 django-staticfiles ，以便压缩的CSS / Javascript和图像从Amazon S3获得。

我设法使用S3作为后端设置staticfiles，所以它是 collectstatic 命令将文件发送到S3而不是 STATIC_ROOT 。

但是，当尝试添加 django-compression 。关于设置远程存储的文档，我创建了一个存储后端的子类， boto ，所以我复制了示例到 storage.py 。一旦我开始使用这个缓存的后端，这些文件被复制到static_media而不是S3。第一页加载后，CACHE文件夹出现在S3和static_media文件夹中。

设置 STATICFILES_STORAGE 和 COMPRESS_STORAGE 返回到boto的正常S3类（ storages.backends.s3boto.S3BotoStorage ）导致静态资产收集到S3 bucket和no static_media文件夹。但是尝试重新加载页面会抛出错误：

 渲染时捕获NotImplementedError：此后端不支持绝对路径。 
  

突出显示 {％compress css％} as标签和 compression / base.py 作为原点。

我的 settings.py ：

  DEFAULT_FILE_STORAGE ='storages.backends.s3boto.S3BotoStorage '
 AWS_ACCESS_KEY_ID ='key'
 AWS_SECRET_ACCESS_KEY ='secret'
 AWS_STORAGE_BUCKET_NAME ='我的桶'
 S3_URL ='http://my-bucket.s3.amazonaws.com /'
 
 MEDIA_ROOT ='client_media'
 MEDIA_URL ='/ media /'
 STATIC_ROOT ='static_media'
 STATIC_URL = S3_URL 
 ADMIN_MEDIA_PREFIX = S3_URL + 'admin /'
 STATICFILES_DIRS =（
 join（DIRNAME，'static'），
）
 STATICFILES_FINDERS =（
'django.contrib.staticfiles.finders.FileSystemFinder '，
'django.contrib.staticfiles.finders.AppDirectoriesFinder'，
'compress.finders.CompressorFinder'，
）
 
 COM PRESS_ENABLED = True 
 COMPRESS_URL = S3_URL 
 COMPRESS_ROOT = STATIC_ROOT 
 COMPRESS_STORAGE ='storage.CachedS3BotoStorage'
 STATICFILES_STORAGE = COMPRESS_STORAGE 
  

那我哪里错了？在使用 CachedS3BotoStorage 自定义存储空间时，是否配置错误？

解决方案

p>您的设置看起来正确。您应该保持 STATICFILES_STORAGE 和 COMPRESS_STORAGE 设置为 storage.CachedS3BotoStorage 而不是切换回 storages.backends.s3boto.S3BotoStorage 。

根据这个 django压缩器问题，问题是django-staticfiles在收集过程中保存的方式（使用 shutil.copy2 ）。 django-staticfiles 的较新版本已更正此问题，其中可以使用，而不是Django 1.3附带的。

  pip install django-staticfiles == dev 
  

在您的 settings.py 中切换到更新版本：

  STATICFILES_FINDERS =（
＃django.contrib.staticfiles.finders.FileSystemFinder，
＃ django.contrib.staticfiles.finders.AppDirectoriesFinder，
staticfiles.finders.FileSystemFinder，
staticfiles.finders.AppDirectoriesFinder，
compress.finders.CompressorFinder，
）
 
 INSTALLED_APPS =（
'django.contrib.auth'，
'django.contrib.contenttypes'，
'django.contrib.sessions'，
＃'django.contrib.staticfiles'，
'staticfiles'，
＃... 
）
  

再次运行 python manage.py collectstatic 后，来自django-compression的CACHE目录和收集的staticfiles文件都应该出现在S3上。 p>

I'm trying to setup django-compressor and django-staticfiles so that the compressed CSS/Javascript and images are served from Amazon's S3.

I've managed to setup staticfiles using S3 as the backend so it's collectstatic command sends the files to S3 instead of STATIC_ROOT.

However when trying to add django-compressor to the mix is where it all seems to fall apart for me. Following the documentation on setting up remote storages I've created a subclass of the storage backend, boto, so I copied the example to storage.py. Once I start using this cached backend the files are copied into static_media and not S3. After the first page load the CACHE folder appears on S3 and in the static_media folder.

Setting STATICFILES_STORAGE and COMPRESS_STORAGE back to boto's normal S3 class (storages.backends.s3boto.S3BotoStorage) results in the static assets being collected into the S3 bucket and no static_media folder. However trying to reload the page throws the error:

Caught NotImplementedError while rendering: This backend doesn't support absolute paths.

highlighting {% compress css %} as the tag and compressor/base.py as the origin.

The s3/staticfiles/compressor section of my settings.py:

DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
AWS_ACCESS_KEY_ID = 'key'
AWS_SECRET_ACCESS_KEY ='secret'
AWS_STORAGE_BUCKET_NAME = 'my-bucket'
S3_URL = 'http://my-bucket.s3.amazonaws.com/'

MEDIA_ROOT = 'client_media'
MEDIA_URL = '/media/'
STATIC_ROOT = 'static_media'
STATIC_URL = S3_URL
ADMIN_MEDIA_PREFIX = S3_URL + 'admin/'
STATICFILES_DIRS = (
    join(DIRNAME, 'static'),
)
STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'compressor.finders.CompressorFinder',
)

COMPRESS_ENABLED = True
COMPRESS_URL = S3_URL
COMPRESS_ROOT = STATIC_ROOT
COMPRESS_STORAGE = 'storage.CachedS3BotoStorage'
STATICFILES_STORAGE = COMPRESS_STORAGE

So where am I going wrong? Have I mis-configured something when using the CachedS3BotoStorage custom storage maybe?

解决方案

Your settings look correct. You should keep both STATICFILES_STORAGE and COMPRESS_STORAGE set to storage.CachedS3BotoStorage though and not switch back to storages.backends.s3boto.S3BotoStorage.

According to this django-compressor issue, the problem is with the way django-staticfiles saves during the collectstatic process (using shutil.copy2). This issue has been corrected in the newer version of django-staticfiles, which can be used instead of the one that ships with Django 1.3.

pip install django-staticfiles==dev

And in your settings.py, switch to the updated version:

STATICFILES_FINDERS = (
    #"django.contrib.staticfiles.finders.FileSystemFinder",
    #"django.contrib.staticfiles.finders.AppDirectoriesFinder",
    "staticfiles.finders.FileSystemFinder",
    "staticfiles.finders.AppDirectoriesFinder",
    "compressor.finders.CompressorFinder",
)

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    #'django.contrib.staticfiles',
    'staticfiles',
    #...
)

After running python manage.py collectstatic again, both the CACHE directory from django-compressor and the collected staticfiles files should show up on S3.
