修改polls/admin.py：

from django.contrib import admin

from .models import Choice, Question

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)

修改polls/models.py：

import datetime

from django.db import modelsfrom django.utils import timezone

class Question(models.Model):    question_text = models.CharField(max_length=200)    pub_date = models.DateTimeField('date published')

    def __str__(self):        return self.question_text

    def was_published_recently(self):        now = timezone.now()        return now - datetime.timedelta(days=1) <= self.pub_date <= now

    was_published_recently.admin_order_field = 'pub_date'    was_published_recently.boolean = True    was_published_recently.short_description = 'Published recently?'

class Choice(models.Model):    question = models.ForeignKey(Question, on_delete=models.CASCADE)    choice_text = models.CharField(max_length=200)    votes = models.IntegerField(default=0)

    def __str__(self):        return self.choice_text
