A Django project which deals with customizing Django Admin Interface. It is impressed from https://books.agiliq.com/projects/django-admin-cookbook/en/latest/ and uses similar/different kind of examples.
To read colourful documentation visit https://hygull.github.io/try-django-admin-cookbook/.
The purpose of this project is to learn by making mistakes so don't think about model's structure first time as later it has been enhanced.
Please focus on how it flows and changes as we advance.
- In
cookbook/urls.py, add the following lines just after import statements
# Admin Interface: change site-header, site-title & index-title
admin.site.site_header = "Admin Interface Cookbook"
admin.site.site_title = "Customizing Admin Interface"
admin.site.index_title = "Apps and related models"so that it will look like below.
Note: I am not going to paste the whole code next time, this is to make sure my point is clear to you readers only first time. So stay active, stay focused.
"""cookbook URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.2/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path
# Admin Interface: change site-header, site-title & index-title
admin.site.site_header = "Admin Interface Cookbook"
admin.site.site_title = "Customizing Admin Interface"
admin.site.index_title = "Apps and related models"
urlpatterns = [
path('admin/', admin.site.urls),
]-
Now create 2 apps named users and posts.
-
Define the following 2 models in users/models.py.
class Address(models.Model):
city = models.CharField(max_length=50, default='', help_text="User's village name")
village = models.CharField(max_length=50, default='', help_text="User's city name")
district = models.CharField(max_length=50, null=True, help_text="User's district name")
state = models.CharField(max_length=50, blank=True, help_text="User's state name")
def __str__(self):
return "Address - {0}".format(self.pk)
class User(models.Model):
first_name = models.CharField(max_length=50, null=False, blank=False, help_text="User's first name")
last_name = models.CharField(max_length=50, null=False, blank=False, help_text="User's last name")
date_of_birth = models.DateField(help_text="User's date of birth")
address = models.ForeignKey(Address, on_delete=models.CASCADE, help_text="User's address")
created_at = models.DateTimeField(auto_now_add=True, help_text="User created at")
updated_at = models.DateTimeField(auto_now=True, help_text="User details last updated at")
active = models.BooleanField(default=True, help_text="Active status")
def __str__(self):
return "User {0}".format(self.pk)- Now, define the following 2 models(including 1 import statement) in posts/models.py.
from users.models import User
class Category(models.Model):
name = models.CharField(max_length=50, help_text="Name of category")
description = models.TextField(default='', help_text="Description of category")
def __str__(self):
return "Category - {0}".format(self.pk)
class Post(models.Model):
title = models.CharField(max_length=50, default='', help_text="Post's title")
description = models.TextField(help_text="Post's description")
posted_by = models.ForeignKey(User, on_delete=models.CASCADE, help_text="Who posted?")
created_at = models.DateTimeField(auto_now_add=True, help_text="Post created at")
updated_at = models.DateTimeField(auto_now=True, help_text="Post last updated at")
category = models.ForeignKey(Category, on_delete=models.CASCADE, help_text="Post belongs to")
active = models.BooleanField(default=True, help_text="Active status")
def __str__(self):
return "Post - {0} by {1}".format(self.pk, self.posted_by.first_name)-
Now, makemigrations & migrate.
-
Add following to users/admin.py.
from users.models import User, Address
@admin.register(User)
class UserAdmin(admin.ModelAdmin):
list_display = [
"pk",
"first_name",
"last_name",
"date_of_birth",
"created_at",
"updated_at",
"active"
]
search_fields = [
"pk",
"first_name",
"last_name"
]
@admin.register(Address)
class AddressAdmin(admin.ModelAdmin):
search_fields = [
"pk",
"city",
"village",
"district",
"state"
]- Now add following to posts/admin.py.
from posts.models import Post, Category
@admin.register(Post)
class PostAdmin(admin.ModelAdmin):
list_display = [
"pk",
"title",
"active",
"posted_by",
"created_at",
"updated_at"
]
search_fields = [
"pk",
"title",
"active"
]
@admin.register(Category)
class CategoryAdmin(admin.ModelAdmin):
search_fields = [
"pk",
"name"
]-
Runserver
python manage.py runserverand check. Now you can see your apps in admin interface. -
You will be seeing Categorys in the page, so just update the Category model by adding Meta class. And it will change Categorys to Categories.
class Category(models.Model):
name = models.CharField(max_length=50, help_text="Name of category")
description = models.TextField(default='', help_text="Description of category")
def __str__(self):
return "Category - {0}".format(self.pk)
class Meta:
verbose_name_plural = "Categories"- Append the following code in users/admin.py (very bottom).
# *---* Separate Admin site *---*
class UserAdminSite(admin.AdminSite):
site_header = "User Admin Site"
site_title = "Users"
index_title = "Users list"
users_admin_site = UserAdminSite(name="users-admin-site")
users_admin_site.register(User)
users_admin_site.register(Address)- Now, append the following code in posts/admin.py (very bottom).
# *---* Separate Admin site *---*
class PostAdminSite(admin.AdminSite):
site_header = "Post Admin Site"
site_title = "Posts"
index_title = "Posts list"
posts_admin_site = PostAdminSite(name="posts-admin-site")
posts_admin_site.register(Post)
posts_admin_site.register(Category)- Open cookbook/urls.py, add first 2 import at very top
from users.admin import users_admin_site
from posts.admin import posts_admin_site- And then only change urlpatterns to
urlpatterns = [
path('admin/', admin.site.urls),
# After defining the following 2 patterns, you won't be able to access
# default home(/) page. Need to design our own custom home(/) page
path('users-admin/', users_admin_site.urls),
path('posts-admin/', posts_admin_site.urls),
]- Now, it's time to hide User & Group (from
django.contrib.authapp) from admin interface. Add the below import statement after the import statements that we added in previous step.
from django.contrib.auth.models import User, Group- Then add the following statements just before urlpatterns list.
# Hide User & Group from admin (/admin/)
admin.site.unregister(User)
admin.site.unregister(Group)
