The development server automatically reloads Python code for each request, as

needed. You don't need to restart the server for code changes to take effect.

However, some actions like adding files or compiling translation files don't

trigger a restart, so you'll have to restart the server in these cases.

.. versionchanged:: 1.7

    Compiling translation files now also restarts the development server.

If you are using Linux and install `pyinotify`_, kernel signals will be used to

autoreload the server (rather than polling file modification timestamps each

* The :djadmin:`runserver` command now uses ``inotify`` Linux kernel signals

  for autoreloading if ``pyinotify`` is installed.

* The :djadmin:`runserver` command is now restarted when a translation file is

  changed.
