*Episode 3* DJANGO (Apps Life Cycle of Django)

 

Apps Life Cycle

    A project is made up of many applications. Each of these applications has an object that could equally be used in any other project. A good example of this is the contact form used on a website, as it can be used on other websites. It should be seen as a module for a project.

•  Creating an Application :-

     Our assumption is that you are in the project folder. The main “project1” folder is similar to the folder “manage.py”.

$ python manage.py startapp myapplication

     At this point, you will have created the application “myapplication” and we can then create the “myapplication” folder with the structure given below:

myapplication/

__init__.py

admin.py

models.py

tests.py

views.py

•   __init__.py- this will ensure that Python handles the folder as a package.
•  admin.py- this helps to make the app be modifiable in admin interface.
•  models.py- this will store all the models for the application.
•  tests.py- this has the unit tests.
•  views.py- this is where the application views are stored.

     Now that we have the application “myapplication”, it is a good time for us to register it to the Django project we previously created, which is “project1”. To do this, update the INSTALLED_APPS tuple located in the file settings.py for our project. This is shown below:

INSTALLED_APPS = (

‘django.contrib.admin’,

‘django.contrib.auth’,

‘django.contrib.contenttypes’,

‘django.contrib.sessions’,

‘django.contrib.messages’,

‘django.contrib.staticfiles’,

‘myapplication’,

)
