Class DatabaseCache

Declaration

Methods

• ▶ def add(self, key, value, timeout=DEFAULT_TIMEOUT, version=None) override

  inherited doc Set a value in the cache if the key does not already exist. If timeout is given, use that timeout for the key; otherwise use the default cache timeout.

  source link

  This method overrides django.core.cache.backends.base.BaseCache.add.

  Return True if the value was stored, False otherwise.

• ▶ def clear(self) override

  inherited doc Remove *all* values from the cache at once.

  source link

  This method overrides django.core.cache.backends.base.BaseCache.clear.

• ▶ def delete(self, key, version=None) override

  inherited doc Delete a key from the cache and return whether it succeeded, failing silently.

  source link

  This method overrides django.core.cache.backends.base.BaseCache.delete.

• ▶ def delete_many(self, keys, version=None) override

  inherited doc Delete a bunch of values in the cache at once. For certain backends (memcached), this is much more efficient than calling delete() multiple times.

  source link

  This method overrides django.core.cache.backends.base.BaseCache.delete_many.

• ▶ def get(self, key, default=None, version=None) override

  inherited doc Fetch a given key from the cache. If the key does not exist, return default, which itself defaults to None.

  source link

  This method overrides django.core.cache.backends.base.BaseCache.get.

• ▶ def get_many(self, keys, version=None) override

  inherited doc Fetch a bunch of keys from the cache. For certain backends (memcached, pgsql) this can be *much* faster when fetching multiple values.

  source link

  This method overrides django.core.cache.backends.base.BaseCache.get_many.

  Return a dict mapping each key in keys to its value. If the given
  key is missing, it will be missing from the response dict.

• ▶ def has_key(self, key, version=None) override

  inherited doc Return True if the key is in the cache and has not expired.

  source link

  This method overrides django.core.cache.backends.base.BaseCache.has_key.

• ▶ def set(self, key, value, timeout=DEFAULT_TIMEOUT, version=None) override

  inherited doc Set a value in the cache. If timeout is given, use that timeout for the key; otherwise use the default cache timeout.

  source link

  This method overrides django.core.cache.backends.base.BaseCache.set.

• ▶ def touch(self, key, timeout=DEFAULT_TIMEOUT, version=None) override

  inherited doc Update the key's expiry time using timeout. Return True if successful or False if the key does not exist.

  source link

  This method overrides django.core.cache.backends.base.BaseCache.touch.
