Python Getting Started to Practice - Djando for Beginners
Installation and initialization
Installing django is actually quite simple, open the command line terminal tool and execute
pip3 install django
For more information about django please follow [official website content](https://www.djangoproject.com/)
Once installed, you need to verify that the installation was successful, which can be done as follows.
After verifying it, move on to the next side and go build a Djando project to get over it. In the command line, type
$ cd djando # Go to a file home that you created (the folder I went into here is named django, you name it whatever you want)
$ django-admin startproject webapp # Create awebapp Job Catalog
$ cd webapp # Once created go intowebapp table of contents
$ py manage.py runserver # Enter the command to run a Django project to see
Performing system checks...

Django version 1.11.6, using settings 'webapp.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
After executing the command, access via browser.
http://127.0.0.1:8000/
The results are as follows
databases
I've just initialized the webapp project I created and run it to see the results, now let's compile the database needed
Go to the project directory and execute the command to compile the database
$ cd webapp
$ py manage.py makemigrations
reimplementation
$ py manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
Applying contenttypes.0001_initial... OK
Applying auth.0001_initial... OK
Applying admin.0001_initial... OK
Applying admin.0002_logentry_remove_auto_add... OK
Applying contenttypes.0002_remove_content_type_name... OK
Applying auth.0002_alter_permission_name_max_length... OK
Applying auth.0003_alter_user_email_max_length... OK
Applying auth.0004_alter_user_username_opts... OK
Applying auth.0005_alter_user_last_login_null... OK
Applying auth.0006_require_contenttypes_0002... OK
Applying auth.0007_alter_validators_add_error_messages... OK
Applying auth.0008_alter_user_username_max_length... OK
Applying sessions.0001_initial... OK
Note: This command basically means to create a database for our project webapp, where makemigrations compiles the database file and migrate gives effect to the compiled database file
If you follow the above command as I output, you have created the database file successfully
To verify and see the results together.
py manage.py runserver
Preview http://127.0.0.1:8000/admin after executing the command
After the backend login screen can be previewed we have to create a username and password to login to the backend
Go to the project folder
$ cd webapp
Execution of orders
$ py manage.py createsuperuser
Enter the login you need to create Username
Username (leave blank to use 'fjun'): fjun
Enter the email address you need to use
Email address: 921516@qq.com
Enter the login password you need to create
Password:
Password to confirm login
Password (again):
Prompt created successfully
Superuser created successfully.
Once created
Running items
$ py manage.py runserver
Open your browser and type
http://127.0.0.1:8000/admin
How you just created a username and password to see the following screen indicates successful access to the backend
Those who come meet in person, those who go forget in the jungle.
