road map

click here to begin my work

• Creating a project

django-admin startproject buddha
python manage.py runserver 0.0.0.0:port

• Creating a app

python manage.py startapp teachings

• Write my first view

Add view
Create urls.py
Modify urlpatterns

• Database setup

//creates any necessary database table according to the database in buddha/settings.py
python manage.py migrate

• Creating models

A model is the single, definitive source of truth about your data. 
It contains the essential fields and behaviors of the data you’re storing. 
Django follows the DRY Principle. 
The goal is to define your data model in one place and automatically derive things from it.

• Activating models

Create a database schema (CREATE TABLE statements) for this app.
Create a Python database-access API for accessing your objects.
add 'teachings.apps.TeachingsConfig' in settings.py
python manage.py makemigrations teachings
python manage.py sqlmigrate teachings 0001
python manage.py migrate

• Three-step guide to making model changes：

Change your models(in models.py)
Run 'python manage.py makemigrations' to create migrations for those changes.
Run 'python manage.py migrate' to apply those changes to the database.
