Part 2: The admin site 

====> Creating an admin user

   Username: admin
   Email address: admin@example.com
   Password: **********
   Password (again): *********
   Superuser created successfully.


====> Start the development server 
$ python manage.py runserver



====> Enter the admin site 
(http://127.0.0.1:8000/admin/)


====> Make the poll app modifiable in the admin
$ edit polls\admin.py

from django.contrib import admin

from .models import Question

admin.site.register(Question)



====> Explore the free admin functionality



====> Customize the admin form
$ edit 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)





====> Split the form up into fieldsets
$ edit 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)




====> Assign arbitrary HTML classes to each fieldset
$ edit 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'], 'classes': ['collapse']}),
    ]

admin.site.register(Question, QuestionAdmin)



====> Adding related objects
$ edit polls\admin.py

from django.contrib import admin

from .models import Choice, Question
# ...
admin.site.register(Choice)

$ edit 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)




====> Change the display style of the related objects in a more compact, table-based format

class ChoiceInline(admin.TabularInline):
    #...



====> Customize the admin change list -- use the list_display admin option
$ edit polls\admin.py

class QuestionAdmin(admin.ModelAdmin):
