⚜What is an ORM?
🛡ORM stands for Object Relational Mapper. It allows you to create and manage your databases easily using models.
🔱A typical model in SQLalchemy might be like that:
Article(Base):
__tablename__ = 'articles'
id = Column(Integer, primary_key=True)
title = Column(String)
author = Column(String)
⚜The advantages are:
- You don't have to use SQL codes
- You don't have to create the table
- Easy CRUD operations.
Adding a record is as easy as
record = Article(title="Religion And Civilisation", author="A. True Scholar")
session.add(record)
other queries demo:
session.query(Task).filter(record.id == some_id).first()
session.query(Task).like(search).all()
💠To Note:
- You might still need SQL for complex operations
- Change in models require the change to propagate. This is achieved using migrations.
