Thanks a lot, Tom, I think this is just what I need, I will try it asap
and see which is better, between the two solutions.
Regards,

Thanks, Tom,
I'm not sure I need to use signals altogether, as I know when a Song
is added. If I make a method in the Song model, I suppose I can
import the model and run it in the shell? Or is there a way I could
run it directly from the admin site?
Yes and yes.
python manage.py shell
>>> from yourapp.models import Song
>>> s = Song.objects.get(title='your title here')
>>> s.make_words()
For the admin interface, look at the actions keyword for admin
classes. Something like
class SongAdmin(admin.ModelAdmin):
...
actions = ['gen_words']
...
def gen_words(self, request, queryset):
for obj in queryset:
obj.make_words()
pass
return
gen_words.description='Generate words for selected songs'
To do the same for all songs at once you can implement a management
command for the command line or if in the admin GUI you will likely
want to implement a GUI button. I'd stayed away from GUI buttons
previously but it turns out to be pretty simple once you have one done.

This nicely enables an automatic path of execution. But if you also
want to execute this code, say, from the admin interface or
separately for testing then you may want to package the fundamental
code into a method of the Song model, then run that method in the
signal handler.
