Module Contents

pylons.decorators.cache.beaker_cache(key='cache_default', expire='never', type=None, query_args=False, cache_headers=('content-type', 'content-length'), invalidate_on_startup=False, cache_response=True, **b_kwargs)

Cache decorator utilizing Beaker. Caches action or other function that returns a pickle-able object as a result.

Optional arguments:

key
None - No variable key, uses function name as key “cache_default” - Uses all function arguments as the key string - Use kwargs[key] as key list - Use [kwargs[k] for k in list] as key
expire
Time in seconds before cache expires, or the string “never”. Defaults to “never”
type
Type of cache to use: dbm, memory, file, memcached, or None for Beaker’s default
query_args
Uses the query arguments as the key, defaults to False
cache_headers
A tuple of header names indicating response headers that will also be cached.
invalidate_on_startup
If True, the cache will be invalidated each time the application starts or is restarted.
cache_response

Determines whether the response at the time beaker_cache is used should be cached or not, defaults to True.

Note

When cache_response is set to False, the cache_headers argument is ignored as none of the response is cached.

If cache_enabled is set to False in the .ini file, then cache is disabled globally.
