django-filters prevents django admin app from starting

[rmunoz10]

Hello,

Trying to add django-filters to my django admin app. App works without filter. But runserver errors out with "The value of 'list_filter[0]' must inherit from 'ListFilter'." when I add "list_filter = (SfAccountFilter,)" to admin.py. See below for details

Not sure what I'm missing

I would appreciate any insight

Thanks

admin.py

from django.contrib import admin

Register your models here.

from .models import SfAccountHierarchy
from .filters import SfAccountFilter

Define the admin class

class SfAccountHierarchyAdmin(admin.ModelAdmin):
list_filter = (SfAccountFilter,)

Register the admin class with the associated model

admin.site.register(SfAccountHierarchy, SfAccountHierarchyAdmin)

---

filters.py

import django_filters
from .models import SfAccountHierarchy

class SfAccountFilter(django_filters.FilterSet):
account_nm = django_filters.CharFilter(lookup_expr='icontains', label='Account Name')
class Meta:
model = SfAccountHierarchy
fields = ['account_nm']

---

models.py

from django.db import models

Create your models here.

from django.urls import reverse # Used in get_absolute_url() to get URL for specified ID

class SfAccountHierarchy(models.Model):
id = models.CharField(primary_key=True, max_length=30, help_text='Account ID')
account_nm = models.CharField(max_length=60)
master_parentid = models.CharField(blank=True, null=True, max_length=30)
master_account_nm = models.CharField(blank=True, null=True, max_length=60)
parentid = models.CharField(blank=True, null=True, max_length=30)
parent_account_nm = models.CharField(blank=True, null=True, max_length=30)
account_nm_alias = models.CharField(blank=True, null=True, max_length=60)
parent_account_nm_alias = models.CharField(blank=True, null=True, max_length=60)

class Meta:
    managed = False
    db_table = 'sf_account_hierarchy'


def __str__(self):
    return self.id


def get_absolute_url(self):
    """Returns the URL to access a detail record for this account."""
    return reverse('account-detail', args=[str(self.id)])

Django Filter's filters are not the same thing as admin filters. You need to use those:
