I tried making fields null=True and/or blank=True still I get the
validation error, why?
With some changes on the whole set-up I got this new error,
Select a valid choice. [u'MNC', u'INT', u'DOM', u'LOC', u'VIR'] is
not one of the available choices.
New setup:
In the model
class BusinessGroup(models.Model):
bgroup_type = models.CharField(max_length=15)
class Business(models.Model):
business_group_choices = models.ManyToManyField(BusinessGroup,
verbose_name= "Business Group", choices=BUSINESS_GROUP)
In Form I have something like,
def __init__(self, *args, **kwargs):
super(BusinessForm, self).__init__(*args, **kwargs)
self.fields['business_group_choices'].widget =
forms.CheckboxSelectMultiple(choices=BUSINESS_GROUP)
I am not sure which is correct approach, I am sorry to say but this is
first I am stuck with poor documentation of Django.
Please!! Any input is greatly appreciated
cheers
