Re: Contact Enquiry model expecting identity value

2009-03-22 Thread grimmus 

Sorry, i am a bit of a beginner at Django and Python.

I am following the contact form tutorial from chapter 7 of the new
book and instead of emailing the form contents i want to save it to a
database.

I referenced the model part from the main Django tutorial on the
website.

Ill have a look into ModelForm, i havent heard of it before

Thanks

You're passing the name as the first param, which is by default the primary
key.  You can avoid that by passing everything as kwargs.

Is there any reason you aren't using a ModelForm though?

Re: Contact Enquiry model expecting identity value

2009-03-22 Thread grimmus 

I am creating an instance of the model in a view like so:

form = ContactForm(request.POST)
if form.is_valid():
cd = form.cleaned_data

c = ContactEnquiry(cd['name'],cd['subject'],cd['email'],cd
['message'],datetime.datetime.now())
c.save()

return HttpResponseRedirect('/contact/thanks/')

if i enter an integer before cd['name'] the instance gets saved in the
database but this integer should be an identity/autonumber value.

How are you creating an instance of the model, can you paste the code you
are running and the full traceback.

Contact Enquiry model expecting identity value

2009-03-22 Thread grimmus 

Hi,

I have a class like so

class ContactEnquiry(models.Model):
name = models.CharField(max_length=100)
subject = models.CharField(max_length=100)
email = models.EmailField()
message = models.CharField(max_length=100)
enquiry_date = models.DateTimeField('enquiry date')
def __unicode__(self):
return self.name

when i make an instance of this class it throws the error :

invalid literal for int() with base 10: 'name value'

when i pass an int as the first parameter it works fine but i thought
an autonumber would be passed as the id value ?

Thanks for any help
