def process_form(request, FormClass, *args, **kwargs):
    """Form processing helpers allowing to keep DRY in views.

    Arguments:

     - ``request``: HttpRequest instance
     - ``FormClass``: form to process
     - ``dest_url``: destination url to redirect after successful form saving.
       If it is not present, then the method ``get_absolute_url`` of object
       returned by form will be used. In case of its unavailability user will be
       redirected to current page.
     - ``on_success``: function to run if form was successfully saved, should
       receive 1 argument.

    ``dest_url`` and ``on_success`` should always be keyword arguments. All
    other arguments are passed directly to FormClass' init.
