MODELS IN DJANGO (create database models, do migrations and use ORM operations)

In Django, model refers to a python object/class which acts as source of information, represents structure of data and provides method to interact with the data. Generally a model maps to a single database table and attributes in the model map to the database table fields. Create a django project and create an app in it: django-admin startproject mytestproject (navigate inside the project like cd mytestproject) python manage.py startalp test1_app In the file models.py : class Articles(models.Model): "to save data in the articles table" title = models.CharField(max_length=150) description = models.TextField() created_by = models.CharField(max_length=150) created_at = models.DateTimeField(default=timezone.now) updated_at = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title class Meta: db_table = 'articles' Save the file and run: python manage.py makemigrations python manage.py migrate ORM(Object-Relational Mapper) is an API acting as a bridge between the django models and the database. ORM provides the pythonic methods to interact to do CRUD operations on the database. To use ORM, activate the shell: python manage.py shell Type: from test_app.models import Articles p1 = Articles(title='test title', description='testing desc notes', created_by='admin') p1.save() Articles.objects.all() Articles.objects.values() Articles.objects.filter(id=1).update(title='updated title') Articles.objects.get(id=1) Articles.objects.get(id=1).delete() There are many other ORM methods.
