Hi,
i have a problem when saving a form for updating.
In my model, i have a field date_created.
Now when i edit the form, i don't want that field to be editable and
thus is don't include it in the field list.
I have specified a form where i specify the fields that i want to see on the
form.
I have left 'date_created' out of there.
In my view, i setup the form like this:
form = ActionForm(request.POST, action)
I thought this would take care of setting the date_created field, apparantly
not.
I get an error when saving the updated form.
IntegrityError at /management/action/edit/9/
null value in column "date_created" violates not-null constraint
This is the form:
class ActionForm(forms.ModelForm):
performed_by =
forms.ModelChoiceField(queryset=User.objects.filter(is_active__exact=True,
is_staff__exact=True).order_by('first_name') )
description = forms.CharField(widget=forms.Textarea(attrs={'cols':'90'}))
class Meta:
model = Action
fields = ('performed_by', 'description', 'public')
The model:
class Action(models.Model):
class Meta:
verbose_name = _('Action')
verbose_name_plural = _('Actions')
db_table = 'calltracking_action'
ordering = ('date_created',)
app_label = 'management'
performed_by = models.ForeignKey(User, limit_choices_to = {'is_staff':True})
date_created = models.DateTimeField("Date action
performed",auto_now_add=True, blank=False)
description = models.TextField()
call = models.ForeignKey(Call)
public = models.BooleanField(default=False)
attachement = models.FileField(upload_to="/files/",blank=True)
def __unicode__(self):
return self.description[:40]
The template only contains labels and fields for the 3 visible fields.
I have the same problem with the call field. I don't want people to be able to
change it.
I now save the info like this in my view:
actionf=form.save(commit=False)
actionf.call = Call.objects.get(pk=action.call.id)
actionf.save()
form.save_m2m()
What is the best solution for this problem?
Should i explicitely set the date_created in the view too? That would mean i
just need to get
it from the existing action but as i said, i thought "form =
ActionForm(request.POST, action)"
took care of that.
Or is it better to specify the fields as hiddenfields?
Thanks
