django-models Getting started with django-models Installation or Setup

Example

Generally, each model maps to a single database table.We to write the field type,limits,size,etc in model.py file of the app. This will create the necessary table and fields in the database.

'''   models.py    '''
from django.db import models
    
    class table_name(models.Model):
        field_name= models.field_type(conditions)

Next we need to inform Django in settinggs.py about the app which will be using this model.

    '''  settinggs.py  ''''
    
    INSTALLED_APPS = [
    #...
    'app_name',
    #...    ]

We are almost done. Next we need to migrate this app so that database tables are created. In terminal type the following:

python manage.py migrate

migrate will create the necessary databases by checking the app_installed in the setting.py

By makemigrations, Django will know the changes that are made to the models.

python manage.py makemigrations

That's it. Your database is created and you can see the schema in the terminal

python manage.py sqlmigrate app_name 0001
