  • Regex on memcached key?

    - by Mickey Cheong
    Hi, Is it possible to grab a list of memcached key based on some regex? I understand that one solution is to store the key in the database and grab the list when I need to delete those keys. This means that, it is going to incur additional cost to the db. I was wondering if there is another way to do it without DB overhead. Cheers, Mickey

  • Edit/show Primary Key in Django Admin

    - by emcee
    It appears Django hides fields that are flagged Primary Key from being displayed/edited in the Django admin interface. Let's say I'd like to input data in which I may or may not want to specify a primary key. How would I go about displaying primary keys in Django-admin, and how could I make specifying it optional? Many thanks in advance, beloved hive-mind.
