hi.
I have a ModelForm based on an Model like this:
class MyModel(models.Model):
attr1 = models.CharField()
attr2 = models.CharField()
attr3 = models.CharField()
createdby = models.ForeignKey(User, related_name='createdby',
db_column='createdbyid')
calculatedfield = models.CharField()
class MyModelForm(ModelForm):
class Meta:
model = MyModel
the attribute fields attr1, attr2 and attr3 are properly shown on my
html page, and correctly restored on my server-side view like this:
def save(request,id):
user = request.user
try:
mymodel = MyModel.objects.get(pk=id)
except:
mymodel = MyModel()
form = MyModelForm(request.POST, instance=mymodel)
now comes the problem: I want to set the createdby attribute only on
my view, AFTER the html page Post. I want to set the createdby and any
other calculated field on server side. is it possible?
I tried:
form['createdby'] = request.user
but it didn't seem to work.
this field (createdby) is NOT NULL and so I wouldn't like to set it to
NULL, save the form with form.save() and later recover the entity
again and manipulate the remaining fields...
any ideas?
thanks in advance.
