Hello,
I'm trying to show the result of a model method in the admin view. My
problem is that the dev server crashes with this error:
Exception Value: 'PersonaAdmin.fieldsets[3][1]['fields']' refers to
field 'age' that is missing from the form.
I have the method 'age' inside a class named 'Persona', and I show it
just putting it in admin.py (following the instructions in Tutorial 1
and 2)
Code:
---models.py
<class here>
def age(self):
today = datetime.date.today()
birth = self.birth_date
diff = today - birth
years = diff/365
return years
---admin.py
class PersonaAdmin(admin.ModelAdmin):
fieldsets = [
('Datos personales', {'fields': \
[('name', 'avatar'),
('lastname', 'nickname'),
('dni', 'birth_date'), 'age']}),
<rest of fieldset and PersonaAdmin class here>
Sorry if it's a stupid question, but i'm just learning Django.
