Test: Custom Filters - Finally, add your custom filter to the CourseAdmin's list_filter attribute.

This is the Task 4 of 4. Finally, add your custom filter to the CourseAdmin's list_filter attribute.

Seems like the easiest thing but I can't get my code to pass. Maybe a fresh set of eyes will help.

courses/admin.py 
from django.contrib import admin

from . import models

class TextInline(admin.StackedInline):
    model = models.Text

class QuizInline(admin.StackedInline):
    model = models.Quiz

class AnswerInline(admin.StackedInline):
    model = models.Answer

class TopicListFilter(admin.SimpleListFilter):
    title = 'topic'
    parameter_name = 'topic'

    def lookups(self, request, model_admin):
        return (('Python',('Python')), ('Ruby',('Ruby')), ('Java',('Java')))

    def queryset(self, request, queryset):
        if self.value() == 'python':
            return queryset.filter(title__contains='python')
        if self.value() == 'ruby':
            return queryset.filter(title__contains='ruby')
        if self.value() == 'java':
            return queryset.filter(title__contains='java')

class CourseAdmin(admin.ModelAdmin):
    inlines = [TextInline, QuizInline]

    list_filter = ['created_at', 'is_live', 'TopicListFilter']

admin.site.register(models.Course, CourseAdmin)

The error you receive is:

Bummer: You need to add the TopicListFilter class to the end of the list_filter property of the CourseAdmin class.

To add the TopicListFilter class you wouldn't enclose it in quotes
