Re: CAS and Django cache

Yes, get followed by set can lead to data loss. What you want is cache.add(). This sets the value if and only if there is no existing value. Its atomic on backends that support it - notably memcached. Sent from my iPhone, please excuse any typos On 27 Oct 2011, at 07:26, Dan Julius wrote:

Localization without translation

Hi, is it possible to have localization available without translation? I've tried to figure this out without much success. What I did was removing the default LANGUAGE_CODE so that Django has to check HTTP_ACCEPT_LANGUAGE header. After that I set USE_I18N = False in my settings and leave USE_L10N

You can run different versions of python using virtualenv [1]. It is hands down the best way to handle multiple python environments. You can use virtualenvwrapper [2] to automate some of the process. I'm not sure how good it is on Mac OS, but you should be fine. I found a link [3] that looks like
