属性误差Django应用程序运行时collectstatic

Question

我收到以下错误，当我运行collectstatic：

AttributeError: 'cStringIO.StringO' object has no attribute 'name' 

一切工作正常，直到我尝试和gzip使用储存“AWS_IS_GZIPPED”我的设置文件（请参阅我的设置.py下面）。

我使用django存储，它利用boto发送我的静态文件到S3和Django压缩器来压缩它们。

这里是我的错误的完整回溯：

这里是我的storage.py

class CachedS3BotoStorage(S3BotoStorage): 
    def __init__(self, *args, **kwargs): 
     super(CachedS3BotoStorage, self).__init__(*args, **kwargs) 
     self.local_storage = get_storage_class('compressor.storage.CompressorFileStorage')() 

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

我也有任何帮助，将不胜感激在我的settings.py

Answer 2

我解决了这个问题是这样的：

的问题是使用相同的[参数内容]保存本地和上传到S3。因为当我们将参数内容传递给super（CachedS3BotoStorage，self）.save（name，content）时，内部参数内容被修改，所以当传递给下一个.save _self.local_storage时。 保存（名称，内容）他与其他国家的AWS_IS_GZIPPED配置相同，即压缩文件内容。 要解决这个问题，只需创建一个内容参数副本。

在settings.py

STATICFILES_STORAGE = 'mypackage.s3utils.CachedS3BotoStorage' 

在mypackage.s3utils.py

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

class CachedS3BotoStorage(S3BotoStorage): 
    """ 
    S3 storage backend that saves the files locally, too. 
    """ 

    location = 'static' 

    def __init__(self, *args, **kwargs): 
     super(CachedS3BotoStorage, self).__init__(*args, **kwargs) 
     self.local_storage = get_storage_class(
      "compressor.storage.CompressorFileStorage")() 

    def url(self, name): 
     """ 
     Fix the problem of dont show the natives images django admin 
     """ 
     url = super(CachedS3BotoStorage, self).url(name) 
     if name.endswith('/') and not url.endswith('/'): 
      url += '/' 
     return url 

    def save(self, name, content): 
     content2 = copy.copy(content) #-> THE SECRET IS HERE 
     name = super(CachedS3BotoStorage, self).save(name, content) 
     self.local_storage._save(name, content2) #-> AND HERE 
     # print id(content) 
     # print id(content2) 
     return name 

    def get_available_name(self, name): 
     if self.exists(name): 
      self.delete(name) 
     return name
