Using django/appengine, how can I present a form which allows entry of certain model fields, and then set additional model fields in code. Calling form.save(commit=False) raises an exception because user is not set. What the correct Django way to handle cases such as this?
I have the following model and form classes:
class FooModel(db.Model):
user = db.UserProperty(required=True)
date = db.DateProperty(required=True)
class FooForm(djangoforms.ModelForm):
class Meta:
model = models.FooModel
exclude = ['user']
And the following request handler code:
if request.method == 'POST':
form = forms.FooForm(request.POST)
# form.save() raises an exception because 'user' is not set
foo = form.save(commit=False)
foo.user = users.get_current_user()
foo.save()
