Django : Excluded fields are saved - django

Question

I have a model :
from django.db import models
from tinymce.models import HTMLField
class Team(models.Model):
name = models.CharField(max_length=100, verbose_name='Team name')
city = models.CharField(max_length=100, verbose_name='Team city')
biography = HTMLField(verbose_name='Team biography')
country = models.ForeignKey('Country')
slug = models.SlugField(max_length=100)
def __str__(self):
return self.name
class Country(models.Model):
name = models.CharField(max_length=100, verbose_name='Country name')
code = models.CharField(max_length=5, verbose_name='Country code')
def __str__(self):
return self.code
And a form for this model:
from django import forms
from teams.models import Team
class TeamForm(forms.ModelForm):
class Meta:
model = Team
fields = (
'biography',
'city',
'country'
)
And this is my view:
def add(request):
if request.method == 'POST':
form = TeamForm(request.POST)
if form.is_valid():
send = True
form.save()
else:
form = TeamForm()
return render(request, 'teams/add.html', locals())
As you can see, all my model fields are required because I don't add argument 'null' to True in my model attributes.
In my ModelForm, for testing, I just specify fields biography, city and country.
But when I fill the form and send-it, data are saved in database, however is missing name and slug....
Why dont i have a django exception ?
Thanks for youre help

Answer 1

Neither of those fields are saved as Null, though. They are both character fields (SlugField is a subclass of CharField), and an empty charfield is saved as an empty string - which is perfectly valid from the database point of view.
