I have two models, Client
and PaymentOptions
.
class Client(models.Model):
name = models.CharField(max_length=50, null=True, unique=False)
contact = models.CharField(max_length=50, null=True, unique=False)
address = models.CharField(max_length=300, null=True, unique=False)
class ClientPaymentOption(models.Model):
name = models.CharField(max_length=30, null=True, unique=False, choices=CARD_TYPE)
action = models.CharField(max_length=30, null=True, unique=False, choices=CLIENT_PAYMENT_OPTION)
percent = models.FloatField(max_length=10, null=True, unique=False)
fixamount = models.FloatField(max_length=20, null=True, unique=False)
itemcharged = models.CharField(max_length=10, null=True, unique=False)
in my admin.py I have this :
admin.site.disable_action('delete_selected')
class ClientAdmin(admin.ModelAdmin):
#display list
list_display = ('name','contact','address')
#display fields
fields = ('name','contact','address')
pass
admin.site.register(Client, ClientAdmin)
class PaymentOptionAdmin(admin.ModelAdmin):
list_display = ('name', 'action', 'percent', 'fixamount', 'itemcharged', 'client')
fields = ('name', 'action','percent', 'fixamount', 'itemcharged', 'client')
admin.site.register(ClientPaymentOption, ClientPaymentOptionAdmin)
is it possible that whenever I create a new Client
in django admin
it will also automatically create it's ClientPaymentOption
?
I try to do this in my admin.py:
class ClientAdmin(admin.ModelAdmin):
#display list
list_display = ('name','b_type','banner','logo',
'contact','address','account_type',
'status','currency','color','user',
)
#display fields
fields = ('name','b_type','banner','logo','contact',
'address','account_type','status',
'currency','color','user',
)
pass
def save_model(self, request, obj, form, change):
ClientPaymentOption.objects.create(name='MasterCard',action='% Charged', client=obj.id, percent=0.10)
ClientPaymentOption.objects.create(name='Visa', action='% Charged',client=obj.id, percent=0.10)
but i got this error:
ValueError at /admin/client_app/client/add/
Cannot assign None: "ClientPaymentOption.client" does not allow null values.
when I try to print
the parameters, i have noticed that the Client still not saved...
print obj.id
None
do anyone have an idea or suggestion about my case?
thanks in advance ...

Call the parent's method before attempting to create the new objects.
