Update dates in models auto

[Juliano Araújo Farias]

Dears,

First I thx for ur attentions... and I novete in Django... but a have a question...

Second:

I have this in my model:

class Actionplan(models.Model):

    date_start_preview = models.DateField('Data Prevista Inicial', blank=True, null=True)

    date_end_preview = models.DateField('Data Prevista Final', blank=True, null=True)

    date_start = models.DateField('Data Real Inicial', blank=True, null=True)

    date_end = models.DateField('Data Real Final', blank=True, null=True)

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')

-----------------------

and I want in admin do:

When the user create a action, the dates in actionplans update with the sum dates...

thx a lot...

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
