Over ride the save() method on teh Actions:
class Actions(models.Model):
date_start_preview = models.DateField('Data Prevista Inicial',
blank=True)
date_end_preview = models.DateField('Data Prevista Final', blank=True)
date_start = models.DateField('Data Real Inicial', blank=True)
date_end = models.DateField('Data Real Final', blank=True)
actionplan = models.ForeignKey(Actionplan, verbose_name='Ações',
related_name='actions')
def save(self, *args, **kwargs):
# if you want the time "now"
self.actionplan.date_start = datetime.datetime.now()
# OR if you want the time to be the same as in the action:
# self.actionplan.date_start = self.date_start
# etc etc, do same for each var
super(Actions, self).save(*args, **kwargs)
(check syntax if you need Timezones:
https://docs.djangoproject.com/en/1.8/topics/i18n/timezones/ , and here are
the docs on method overriding:
https://docs.djangoproject.com/en/1.8/topics/db/models/#overriding-predefined-model-methods
)
cheers
