polls/admin.py

from django.contrib import admin
    
    from .models import Question
    
    
    class QuestionAdmin(admin.ModelAdmin):
        fieldsets = [
            (None,               { 'fields': ['question_text']}),
            ('Date information', { 'fields': ['pub_date']}),

## 添加Choice ##

### 方法一 ###

from django.contrib import admin
    
    from .models import Question, Choice
    
    
    class QuestionAdmin(admin.ModelAdmin):
        fieldsets = [
            (None,               { 'fields': ['question_text']}),
            ('Date information', { 'fields': ['pub_date']}),
        ]
    
    
    admin.site.register(Question, QuestionAdmin)
    admin.site.register(Choice)

对于外键类型，系统会自动生成选择框，而且点击加号，可以创建新的Question

### 方法二 ###

from django.contrib import admin
    
    from .models import Choice, Question
    
    
    class ChoiceInline(admin.StackedInline):
        model = Choice
        extra = 3
    	# extra 每次点击会额外生成3个choice
    
    class QuestionAdmin(admin.ModelAdmin):
        fieldsets = [
            (None,               { 'fields': ['question_text']}),
            ('Date information', { 'fields': ['pub_date'], 'classes': ['collapse']}),
        ]
        inlines = [ChoiceInline]
    
    admin.site.register(Question, QuestionAdmin)

## 完善admin ##

from django.contrib import admin
    
    from .models import Choice, Question
    
    
    class ChoiceInline(admin.StackedInline):
        model = Choice
        extra = 3
    
    
    class QuestionAdmin(admin.ModelAdmin):
        fieldsets = [
            (None,               { 'fields': ['question_text']}),
            ('Date information', { 'fields': ['pub_date'], 'classes': ['collapse']}),
        ]
        inlines = [ChoiceInline]
        # 更多list_display信息https://docs.djangoproject.com/en/2.2/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display
        list_display = ('question_text', 'pub_date', 'was_published_recently')
        list_filter = ['pub_date']
        search_fields = ['question_text']
    
    
    admin.site.register(Question, QuestionAdmin)

polls/models.py修改Question

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