I've been looking at this for a couple hours and I can't seem to get a handle on why I'm getting this message...
int() argument must be a string or a number, not 'tuple'
on this line from my views.py (NOTE: Exception actually occurrs one level deeper inside django core, but this my line of code which eventually triggers the exception)...
service_interest = ServiceInterest.objects.get_or_create(service = service, client = client)
Why am I getting this error? For your benefit, see below models.py, a forms.py, and a snippet from views.py.
models.py:
class Client(models.Model):
name = models.CharField(max_length=100)
email = models.EmailField()
site = models.URLField()
contact_date = models.DateField(default = datetime.date.today())
class Service(models.Model):
name = models.CharField(max_length=200)
class ServiceInterest(models.Model):
service = models.ForeignKey('Service')
client = models.ForeignKey('Client')
class Meta:
unique_together = ("service", "client")
forms.py...
class ContactForm(forms.Form):
SERVICE_CHOICES = (
('first_choice', 'Description of first choice'),
('second_choice', 'Description of second choice'),
('third_choice', 'Description of third choice'),
('other', 'Other')
)
SERVICE_CHOICES_DICT = dict(SERVICE_CHOICES)
name = forms.CharField(label='What would you like us to call you?', max_length=200, required=False)
email = forms.EmailField(label='What is your email address?', help_text='Ex: [email protected]')
url = forms.URLField(label='If you have a website, please provide a link', required=False, help_text="Ex: www.yoursite.com")
service_interest = forms.MultipleChoiceField(label="Please check all of the services you're interested in:", widget=forms.widgets.CheckboxSelectMultiple, choices=SERVICE_CHOICES, required=True)
other = forms.CharField(label='If you selected \"Other\", please specify:', max_length=200, required=False)
message = forms.CharField(max_length=10000, required=False, label='Any other information you think we should know?', widget=forms.widgets.Textarea)
def clean_other(self):
cleaned_data = super(ContactForm, self).clean()
if 'service_interest' in cleaned_data.keys():
options = cleaned_data['service_interest']
if 'other' in options:
other_input = cleaned_data['other']
if other_input == None or len(other_input) == 0:
raise forms.ValidationError('Required when \"Other\" is checked')
return cleaned_data
relevent code from views.py:
name = form.cleaned_data['name']
email = form.cleaned_data['email']
url = form.cleaned_data['url']
interests = form.cleaned_data['service_interest']
other = form.cleaned_data['other']
message = form.cleaned_data['message']
client = Client.objects.get_or_create(name = name, email = email, site = url)
for interest in interests:
service = None
if(interest != 'other'):
service = Service.objects.get_or_create(name = ContactForm.SERVICE_CHOICES_DICT[interest])
else:
service = Service.objects.get_or_create(name = other)
# Appears to be responsible for the stack trace, even though exception
# is one level deeper in...
# /Library/Python/2.7/site-packages/django/core/handlers/base.py in get_response
service_interest = ServiceInterest.objects.get_or_create(service = service, client = client)
get_or_create
returns a tuple, in the form of (instance, created)
. The second parameter tells you whether it had to create it or not, obviously enough. Do the following instead:
client, created = Client.objects.get_or_create(name = name, email = email, site = url)
