Question

I’m working on writing the models.py file, and I need some controls to perform the automatic compilation of some fields.

MOTIVOINGRESSO = (
         (u'sequestro ', u'sequestro'),
         (u'fermo ', u'fermo'),
         (u'confisca final ', u'confisca final'),
         (u'cambio custodian ', u'cambio custodian'),
     )
     motivo_ingresso = models.CharField (max_length = 50, choices = MOTIVOINGRESSO)


FERMO = (
         (u'30 ', u'30'),
         (u'60 ', u'60'),
         (u'90 ', u'90'),
         (u'180 ', u'180'),
         (u'1 month ', u'1 month'),
         (u'3 months, 'u'3 months'),
         (u'indeterminato ', u'indeterminato'),
     )
     durata_in_giorni_del_fermo = models.CharField (max_length = 20, choices = STOPPED, blank = True)

If the administrator the choice click 'sequestro', in durata_in_giorni_del_fermo will automatically selected 'indeterminato'.
Should I report the values ​​entered? or machine cycles if within the models?

Any Ideas?

Its very easy if you will do it through Jquery in template. I don’t know, this can be possible in models.py. Below links are much relevant to your question.
