Hola,
After successfully implementing two range based filters using the admin's
list_filter
docs:
PATH/ref/contrib/admin/index.html#django.contrib.admin.ModelAdmin.list_filter
I've added one more filter, but now I'm getting a NotImplementedError and I
can't see what I've done wrong. The model has a field called "island" and I
would like to distinguish between the main island and the "outer islands"
(all the rest). Note the commented out returns - me trying to find any
subtle changes to fix this:
class IslandFilter(admin.SimpleListFilter):
title = 'islands'
parameter_name = 'island'
def lookup(self, request, model_admin):
return (
('tarawa', 'Tarawa'),
('outer-islands', 'Outer Islands'),
)
def queryset(self, request, queryset):
if self.value == 'tarawa':
return queryset.filter(island=='Tarawa')
#return queryset.filter(island__exact='Tarawa')
else:
return queryset.exclude(island=='Tarawa')
#return queryset.exclude(island__exact='Tarawa')
class ApplicantAdmin(admin.ModelAdmin):
list_filter = ('gender', 'disability', MathTestFilter,
EnglishTestFilter, IslandFilter,'successful', 'applied_for', 'eligibility')
Can anyone see what I've done wrong please?
Cheers
L.
