When I register my model to the admin it doesn't allow me to use a
method in list_filter :(
This pseudo code should explain my situation:
class MyModel:
gender = models.CharField()
age = models.IntegerField()
@property
def man(self):
return self.gender == 'male' and self.age > 18
objects = SpecialManager()
The special manager I use makes it possible to do this:
>>> MyModel.objects.filter(man=True)
I achived that by wrapping filter() and exclude(). No big deal.
The admin is registered like this:
class MyModelAdmin(admin.ModelAdmin):
list_display = ('__unicode__', 'user', 'man')
list_filter = ('man', ) # thise causes the ImproperlyConfigured
error!
def man(self, object_):
return object_.man
man.short_description = 'Man?'
man.allow_tags = False
admin.site.register(MyModel, MyModelAdmin)
Why can't I use methods instead of fields in list_filter?
Is there a solution to this problem?
