Hi,
I am relatively new to Django, and am trying to update a many-to-many
related table using a ModelForm.
I see fro the documentation that if I use save(commit=False) - which I
do - I need to use save_m2m() after saving the initial form. I am
using the save_m2m(), but my related table does not get updated.
Any help appreciated.
I am using django V1.3.1 on linux using Postgresql as the db.
Details:
The Model:
class srvorders(models.Model):
client = models.CharField('Client', max_length=200)
server = models.CharField('Server Type', max_length=200)
os = models.CharField('Operating System', max_length=200)
osopts = models.CharField('Operating System Options',
max_length=200, blank=True, null=True)
ordertotal = models.IntegerField()
notes = models.TextField('Notes', blank=True, null=True)
orderdate = models.DateTimeField()
orderIP = models.IPAddressField()
status = models.CharField('Order Status', max_length="20")
srvopts = models.ManyToManyField(srvoptions, blank=True,
null=True)
class Meta:
ordering = ["id"]
verbose_name_plural = "Server Orders"
def __unicode__(self):
return str(self.id)
class Admin:
pass
The ModelForm:
class NewOrderForm(forms.ModelForm):
Server_CHOICES = [('', '-- choose a Server --'), ] + [(s.id,
s.name) for s in products.objects.all()]
OS_CHOICES = [('', '-- choose a Server --'), ] +[(o.id, o.name)
for o in OS.objects.all()]
OPTION_CHOICES = [('', '-- choose a Server --'), ] +[(opt.id,
opt.name) for opt in osoptions.objects.all()]
server=forms.ChoiceField(choices=Server_CHOICES)
os = forms.ChoiceField(choices=OS_CHOICES)
osopts=forms.ChoiceField(choices=OPTION_CHOICES, required=False)
ordertotal=forms.CharField(required=False)
notes=forms.CharField(required=False)
class Meta:
model= srvorders
exclude = ('client', 'orderdate', 'orderIP', 'status')
The View snippet:
if request.method == 'POST':
form = NewOrderForm(request.POST)
if form.is_valid():
new_item = form.save(commit=False)
new_item.client = orderClient
new_item.orderdate = datetime.now()
new_item.orderIP = remote_ip
new_item.status = "Not_Paid"
new_item.save()
form.save_m2m()
Regards,
Leslie
