generally you should keep this type of business logic out of the model
the place to put it is either in the Form
or the view
class OrderModelForm(forms.ModelForm):
class Meta:
model = Order
def save_model(self, request, obj, form, change):
"""
Given a model instance save it to the database.
"""
if not change: # only when adding
obj.created_by = request.user
if(not obj.from_email):
obj.from_email = request.user.email
#create your invoice now
obj.save()
# and if you are using that in the admin then add it to the admin too:
class OrderAdmin(admin.ModelAdmin):
form = OrderModelForm
and register it
