配置約翰尼緩存

我想在我的開發機器上設置約翰尼緩存，但我遇到了一些問題。使用基於文件的緩存是這樣的：配置約翰尼緩存

CACHES = { 
    'default' : dict(
     BACKEND= 'johnny.backends.filebased.FileBasedCache', 
     LOCATION= '/tmp', 
    ) 
} 

MIDDLEWARE_CLASSES = (
    'johnny.middleware.LocalStoreClearMiddleware', 
    'johnny.middleware.QueryCacheMiddleware', 
)

我得到：

Traceback (most recent call last): 
    File "/Users/kitsunde/.virtualenvs/media-pop/lib/python2.7/site-packages/django/core/servers/basehttp.py", line 283, in run 
    self.result = application(self.environ, self.start_response) 
    File "/Users/kitsunde/.virtualenvs/media-pop/lib/python2.7/site-packages/django/contrib/staticfiles/handlers.py", line 68, in __call__ 
    return self.application(environ, start_response) 
    File "/Users/kitsunde/.virtualenvs/media-pop/lib/python2.7/site-packages/django/core/handlers/wsgi.py", line 273, in __call__

    self.exiting(exc_value, self.using) 
    File "/Users/kitsunde/.virtualenvs/media-pop/lib/python2.7/site-packages/django/db/transaction.py", line 281, in exiting 
    commit(using=using) 
    File "/Users/kitsunde/.virtualenvs/media-pop/lib/python2.7/site-packages/johnny/transaction.py", line 147, in newfun 
    self._flush(commit=commit, using=using) 
    File "/Users/kitsunde/.virtualenvs/media-pop/lib/python2.7/site-packages/johnny/transaction.py", line 135, in _flush 
    self.cache_backend.set(key, value, self.timeout) 
    File "/Users/kitsunde/.virtualenvs/media-pop/lib/python2.7/site-packages/johnny/backends/filebased.py", line 23, in set 
    return super(CacheClass, self).set(key, value, timeout=timeout, **kwargs) 
NameError: global name 'kwargs' is not defined

如果我嘗試使用基於一個記憶：

CACHES = { 
    'default' : { 
     'BACKEND': 'johnny.backends.locmem.LocMemCache', 
    } 
}

連接只是掛在那裏。我現在打開了零緩存。任何想法如何設置？

你發現了一個在JohnnyCache基於文件的後端的錯誤。請注意，我具有相同的版本，Memcached後端可以工作，因此您可以使用它。 – jpic 2012-02-29 07:36:07

您在JohnnyCache文件的後端發現了一個錯誤。我有同樣的錯誤，但是我設法讓FileBased後端工作。我通過將這些代碼放在settings.py中修正了這個錯誤：

import sys 
from johnny.backends import filebased 
def fixed_set(self, key, value, timeout=None): 
    if timeout is 0: 
     timeout = sys.maxint 
    return super(filebased.CacheClass, self).set(key, value, timeout=timeout) 
filebased.CacheClass.set = fixed_set

但是，您應該報告錯誤。

注意：我推薦的memcached後端開箱即用，超級超快！

我不明白你爲什麼只有兩個中間件。你不應該有這樣的：

MIDDLEWARE_CLASSES = [ 
    'johnny.middleware.LocalStoreClearMiddleware', 
    'johnny.middleware.QueryCacheMiddleware', 
    'django.middleware.common.CommonMiddleware', 
    'django.contrib.sessions.middleware.SessionMiddleware', 
    'django.middleware.transaction.TransactionMiddleware', 
    'django.middleware.csrf.CsrfViewMiddleware', 
    'django.contrib.auth.middleware.AuthenticationMiddleware', 
    'django.contrib.messages.middleware.MessageMiddleware', 
]
