Practical drills of "Python efficient development practices"-application Building 2 and python efficient development practices

To develop practical applications that conform to the MVC Architecture in the project, you need to create a Django application in the project. Each Django project can contain multiple Django applications. The syntax for creating an application is:

# Python manage. pystartapp Application name

Manage. py is a command line tool generated in the project directory when a project is created. startapp is a command keyword, for example:

 

#cd djangosite#python manage.py startapp

 

After the command is complete, the following directory and file structure will be created in the project directory:

App/

_ Init _. py

Admin. py

Apps. py

Migrations/

_ Init _. py

Models. py

Tests. py

Views. py

The file function is parsed as follows:

 

• _ Init _. py: NO content exists. The existence of this file makes the app a Python package.
• Admin. py: manages the site model declaration file, which is empty by default.
• Apps. py: application information definition file. The AppConfig class is generated, which is used to define Meta data such as the application name.
• Migrations package: used to define the reference migration function.
• Models. py: file used to add data classes at the model layer.
• Tests. py: test the code file.
• Views. py: defines the URL response function.

 

All the above files have no actual content at the time of application creation, and developers need to write code to complete their functions.
