search_fields = ['question_text'] from Tutorial07 not working.

[Patrick Kyne]

Following the django tutorial from the beginning, everything works as it should except the Search Fields example in Tutorial 07.

Following the tutorial, my polls/admin.py appears below. However, no search field appears in Google Chrome or in Firefox. No error is thrown by the django server either. I did not find any relevant google responses to the issue, nor did I find it here in Trac.

## polls/admin.py:
from django.contrib import admin

# Register your models here.

from .models import Question, Choice

class ChoiceInline(admin.TabularInline):
    model = Choice
    extra = 3


class QuestionAdmin(admin.ModelAdmin):
    fieldsets = [
        (None,               {'fields': ['question_text']}),
        ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),
    ]
    inlines = [ChoiceInline]

    list_display = ('question_text', 'pub_date', 'was_published_recently')

    list_filter = ['pub_date']

    search_fields = ['question_text']

admin.site.register(Question, QuestionAdmin)

I've tested it with both the search_fields as:

search_fields = ['question_text']

-and-

search_fields = ['question_text', 'pub_date']

to see if there were any difference or error thrown. No difference. No search field is displayed, and no error is thrown.
