Explanation to Create a Project, Creation of Apps and their Structure, Working with ADMIN Console Django - Creating a Project
Now that we have installed Django, let's start using it. In Django, every web app you want to create is called a project; and a project is a sum of applications. An application is a set of code files relying on the MVT pattern. As example let's say we want to build a website, the website is our project and, the forum, news, contact engine are applications. This structure makes it easier to move an application between projects since every application is independent. Create a Project Whether you are on Windows or Linux, just get a terminal or a cmd prompt and navigate to the place you want your project to be created, then use this code − $ django-admin startproject myproject This will create a "myproject" folder with the following structure − myproject/ manage.py myproject/ init.py settings.py urls.py wsgi.py The Project Structure The “myproject” folder is just your project container, it actually contains two elements − manage.py − This file is kind of your project local django-admin for interacting with your project via command line (start the development server, sync db...). To get a full list of command accessible via manage.py you can use the code − $ python manage.py help The “myproject” subfolder − This folder is the actual python package of your project. It contains four files − init.py − Just for python, treat this folder as package. settings.py − As the name indicates, your project settings. urls.py − All links of your project and the function to call. A kind of ToC of your project.
Django - Apps Life Cycle A project is a sum of many applications. Every application has an objective and can be reused into another project, like the contact form on a website can be an application, and can be reused for others. See it as a module of your project. Create an Application We assume you are in your project folder. In our main “myproject” folder, the same folder then manage.py − $ python manage.py startapp myapp You just created myapp application and like project, Django create a “myapp” folder with the application structure − myapp/ init.py admin.py models.py tests.py views.py init.py − Just to make sure python handles this folder as a package. admin.py − This file helps you make the app modifiable in the admin interface. models.py − This is where all the application models are stored. tests.py − This is where your unit tests are. views.py − This is where your application views are. Get the Project to Know About Your Application
At this stage we have our "myapp" application, now we need to register it with our Django project "myproject". To do so, update INSTALLED_APPS tuple in the settings.py file of your project (add your app name) − INSTALLED_APPS =( 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'myapp',) Django - Admin Interface Django provides a ready-to-use user interface for administrative activities. We all know how an admin interface is important for a web project. Django automatically generates admin UI based on your project models. Starting the Admin Interface The Admin interface depends on the django.countrib module. To have it working you need to make sure some modules are imported in the INSTALLED_APPS and MIDDLEWARE_CLASSES tuples of the myproject/settings.py file. For INSTALLED_APPS make sure you have − INSTALLED_APPS =( 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'myapp',) For MIDDLEWARE_CLASSES − MIDDLEWARE_CLASSES =( 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware',) Before launching your server, to access your Admin Interface, you need to initiate the database −
That interface will let you administrate Django groups and users, and all registered models in your app. The interface gives you the ability to do at least the "CRUD" (Create, Read, Update, Delete) operations on your models. 8.Activities/ Case studies/related to the session—NA 9.Examples&contemporary extracts of articles/ practices to convey the idea of the session---NA 10.Table Numbering---NA 11Figures with captions—NA 12.SAQ's-Self Assessment Questions:
