Dear Folks,
I have an Admin form which has two textfields namely country and state. I
have made it more user friendly by making textfield a dropdown with the
value to select for those fields.
The model i have has some constraints which I cannot change i.e. that the
country value must be a 2 letters in length such as 'US' for United States
as these codes are unique. Simlarly for states of a country which can have
code up to 10 letters in length. Since my dropdown contains the names and
not the codes I need a way to excude them from validation change there
values so that they are database friendly and save them.
After much research I came across two methods full_clean() and
clean_fields() which is where the key lies but I have no idea how to use
them.
So far the validation errors on country and state keep firing and there
does not seem a way to stop it. Secondly if you exclude fields from
validation do I access them directly using the POST data and modify them
before saving?
The relevant code is below:
class GroupAdminForm(forms.ModelForm):
creator =
CustomCreatorChoiceField(queryset=User.objects.order_by('last_name'))
country =
CustomLocationChoiceField(queryset=Country.objects.order_by('name'))
state =
CustomLocationChoiceField(queryset=Subdivision.objects.order_by('name'))
def clean_fields(self, exclude=['country', 'state']): # or I could use
full_clean
print "Inside clean_fields"
return
def __init__(self, *args, **kwargs):
super(GroupAdminForm, self).__init__(*args, **kwargs)
self.fields['country'].initial = DEFAULT_COUNTRY
My model is below:
class Group(models.Model):
# Name of the group
name = models.CharField(max_length=100)
# Longer description of group
description = models.TextField(blank=True)
# Group owner
creator = models.ForeignKey(User, related_name='groups_created')
# Creation date
creation_date = models.DateTimeField()
# Country foreign key to Country table in Geography App
country = models.CharField(max_length=2, null=True, default='US')
# State foreign key to State table in Geography App
state = models.CharField(max_length=10, null=True, blank=True)
# City where group is located
city = models.CharField(max_length=40, null=True, blank=False)
# Public (searchable) group
public = models.BooleanField(default=True, null=False)
Please do let me know if anything else is needed.
Cheers,
nav
