Making queries to create , save , and update with save(), create(), set(), add() p9 | Django in deep

Once you’ve created your data models, Django automatically gives you a database-abstraction API that

lets you create, retrieve, update and delete objects. This tutorial explains how to use this API.

#creating objects

To represent #database-table data in #python objects, #django uses an intuitive system
A model class represents
a #database table, and an instance of that class represents a particular record in the database table.
To create an object, instantiate it using keyword arguments to the model class, then call save() to save it to
the database or use the #create () method to create and save the object in one single line of code .

Saving changes to objects
To save changes to an object that’s already in the database, use #save () .
