Customing the admin site

1. Customize the admin form

   # polls/admin.py
   from django.contrib import admin
   from .models import Question
   
   class QuestionAdmin(admin.ModelAdmin):
       fields = ['pub_date', 'question_text']
   
   admin.site.register(Question, QuestionAdmin)
   

   # 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']}),
       ]
   
   admin.site.register(Question, QuestionAdmin)
   

2. Adding related objects

   # polls/admin.py
   from django.contrib import admin
   from .models import Choice, Question
   # ...
   admin.site.register(Choice)
   

   # polls/admin.py
   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]
   
   admin.site.register(Question, QuestionAdmin)
   

   # polls/admin.py
   class ChoiceInline(admin.TabularInline):
       #...
   

3. Customize the admin change list

   polls/admin.py
   class QuestionAdmin(admin.ModelAdmin):
       # ...
       list_display = ('question_text', 'pub_date')
   

   # polls/admin.py
   class QuestionAdmin(admin.ModelAdmin):
       # ...
       list_display = ('question_text', 'pub_date', 'was_published_recently')
   

   # polls/models.py
   class Question(models.Model):
       # ...
       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?'
   

   list_filter = ['pub_date']
   

   search_fields = ['question_text']
   

4. Customizing your project’s templates

   # mysite/settings.py
   TEMPLATES = [
       {
           'BACKEND': 'django.template.backends.django.DjangoTemplates',
           'DIRS': [os.path.join(BASE_DIR, 'templates')],
           'APP_DIRS': True,
           'OPTIONS': {
               'context_processors': [
                   'django.template.context_processors.debug',
                   'django.template.context_processors.request',
                   'django.contrib.auth.context_processors.auth',
                   'django.contrib.messages.context_processors.messages',
               ],
           },
       },
   ]
   

   # Where are the Django source files?
   $ python -c "import django; print(django.__path__)"
   

   {% block branding %}
   <h1 id="site-name"><a href="{% url 'admin:index' %}">Polls Administration</a></h1>
   {% endblock %}
