copied!<p>So, using the <a href="http://turbogears.org/2.1/docs/main/Caching.html" rel="nofollow">TurboGears documentation</a> as a guide, what settings do you have for the url?</p> <pre><code>[app:main] beaker.cache.type = ext:memcached beaker.cache.url = 127.0.0.1:11211 # you can also store sessions in memcached, should you wish # beaker.session.type = ext:memcached # beaker.session.url = 127.0.0.1:11211 </code></pre> <p>It looks to me as if <a href="https://github.com/tav/pylibs/blob/master/beaker/ext/memcached.py" rel="nofollow">memcached requires a url</a> to initialize correctly:</p> <pre><code>def __init__(self, namespace, url=None, data_dir=None, lock_dir=None, **params): NamespaceManager.__init__(self, namespace) if not url: raise MissingCacheParameter("url is required") </code></pre> <p>I am not really sure why the code allows url to be optional (defaulting to None) and then requires it. I think it would have been simpler just to require the url as an argument.</p> <hr> <p>Later: in response to your next question:</p> <blockquote> <p>when I used cache.url I've got next error: AttributeError: 'MemcachedNamespaceManager' object has no attribute 'lock_dir'</p> </blockquote> <p>I'd say that the way I read the code below, you have to provide either <code>lock_dir</code> or <code>data_dir</code> to initialize self.lock_dir:</p> <pre><code> if lock_dir: self.lock_dir = lock_dir elif data_dir: self.lock_dir = data_dir + "/container_mcd_lock" if self.lock_dir: verify_directory(self.lock_dir) </code></pre> <p>You can replicate that exact error using this test code:</p> <pre><code>class Foo(object): def __init__(self, lock_dir=None, data_dir=None): if lock_dir: self.lock_dir = lock_dir elif data_dir: self.lock_dir = data_dir + "/container_mcd_lock" if self.lock_dir: verify_directory(self.lock_dir) f = Foo() </code></pre> <p>It turns out like this:</p> <pre><code>>>> f = Foo() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<stdin>", line 7, in __init__ AttributeError: 'Foo' object has no attribute 'lock_dir' </code></pre>
