Hi Everyone,
I am quite new to Django(4months actually), I am struggling with this
problem for last 2 days, I think I am making some stupid mistake. Any
help or input is highly appreciated. I am using Django 1.3, so old
(1.1 -) solutions are not helpful much actually there are many on
stack-overflow.
In the model I have,
BUSINESS_GROUP = (
('MNC','Multinational'),
('INT','International (Export/Import)'),
('DOM','Domestic/National'),
('LOC','Local'),
('VIR','Virtual'),
)
class BusinessGroup(models.Model):
bgroup_type = models.CharField(max_length=15, choices =
BUSINESS_GROUP, blank = True, null = True)
class Business(models.Model):
business_group_choices = models.ManyToManyField(BusinessGroup,
verbose_name= "Business Group")
In Form I am doing like,
def __init__(self, *args, **kwargs):
self.fields['business_group_choices'].widget =
forms.CheckboxSelectMultiple(choices=BUSINESS_GROUP)
My view looks like,
if request.method == 'POST':
form = BusinessForm(request.POST, instance = business)
#print request
#print form
if form.is_valid():
new_business = form.save(commit=False)
new_business.created_by = request.user
new_business.is_blocked=False
form_values = form.cleaned_data
new_business.save()
assign('edit_business', request.user, new_business)
return
HttpResponseRedirect(new_business.get_absolute_url())
I am getting error like this,
"DOM" is not a valid value for a primary key.
"INT" is not a valid value for a primary key.
etc.
I found source of error here in Django model source,
http://www.java2s.com/Open-Source/Python/Web-Frameworks/Django/django/forms/models.py.htm
But not clear how to interpret and workout this problem.
