Generalised insert into sqlalchemy using dictionary

Generalised insert into sqlalchemy using dictionary

To perform a generalized insert operation using SQLAlchemy with a dictionary in Python, you can follow these steps:

  • Import Required Modules: Import the necessary modules from SQLAlchemy.
from sqlalchemy import create_engine, Column, Integer, String
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
  • Connect to Database: Create an SQLAlchemy engine and establish a connection to your database.
# Replace with your database URL
DATABASE_URL = "sqlite:///my_database.db"
engine = create_engine(DATABASE_URL)

Base = declarative_base()
  • Define a Model: Define an SQLAlchemy model that corresponds to the table you want to insert data into.
class MyTable(Base):
    __tablename__ = 'my_table'

    id = Column(Integer, primary_key=True)
    name = Column(String)
    age = Column(Integer)
  • Create Session: Create a session using the sessionmaker with the created engine.
Session = sessionmaker(bind=engine)
session = Session()
  • Insert Data: Define a function that takes a dictionary containing data to be inserted into the database.
def insert_data(data_dict):
    new_record = MyTable(**data_dict)
    session.add(new_record)
    session.commit()
  • Usage: Now you can use the insert_data function to insert data into your database.
if __name__ == "__main__":
    data = {"name": "Alice", "age": 25}
    insert_data(data)

This example demonstrates a generalized way to insert data using SQLAlchemy. You can customize the model and dictionary according to your specific use case.

Please remember to customize the database URL (DATABASE_URL) to match your database configuration, and adjust the model class (MyTable) and dictionary keys to match your table structure and data.
