<!------------------------- New Learning in this project ------------------------------------------->

### Add new column or Database table change
	-> delete migration file except __init__.py 
	-> python manage.py makemigrations posts  [posts is app name]
	-> python manage.py migrate --fake posts zero
	-> python manage.py migrate posts

			otherwise --
			Initialize migrations for your existing models:

		./manage.py makemigrations myapp
		Fake migrations for existing models:

		./manage.py migrate --fake myapp
		Add the new field to myapp.models:

		from django.db import models

		class MyModel(models.Model):
			... #existing fields
			newfield = models.CharField(max_length=100) #new field
		Run makemigrations again (this will add a new migration file in migrations folder that add the newfield to db):

		./manage.py makemigrations myapp
		Run migrate again:

		./manage.py migrate myapp
