[PYTHON] WEB application development using Django [Initial settings]

Continued from the startup

Make initial settings for developing WEB applications. Edit the settings.py file in project1 in the project1 folder. This time, we will use Atom as an editor.

Edit settings.py

In settings.py, database settings and authentication are described. Sqlite3 is set as the standard for Django. (However, sqlite seems to use PostgreSQL or MySQL in the production environment because the response becomes slow as the number of accesses increases.) First, change the "Language setting" and "Time zone".

#Language setting
#LANGUAGE_CODE = 'en-us'

#Time zone setting
TIME_ZONE = 'Asia/Tokyo'

Then start the Django server and check for changes.

$ python3.6 manage.py runserver

You can check the startup screen by entering "" in the browser. screencapture-127-0-0-1-8000-2020-09-14-07_24_17.png I was able to confirm that it would change to Japanese.

Stop the server with Control + C at the command prompt.

Next, perform migration. You can create a database table by migrating.

$ python3.6 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 admin.0003_logentry_add_action_flag_choices... 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 auth.0009_alter_user_last_name_max_length... OK
  Applying auth.0010_alter_group_name_max_length... OK
  Applying auth.0011_update_proxy_permissions... OK
  Applying auth.0012_alter_user_first_name_max_length... OK
  Applying sessions.0001_initial... OK

You have successfully created the database. We will be adding the necessary information to this table in the future.
