How To Install Sqlalchemy-Imageattach

In this guide, we’ll walk through the installation process and provide a simple code example to demonstrate how to use SQLAlchemy-ImageAttach.

What is Sqlalchemy-Imageattach?

SQLAlchemy-ImageAttach is a powerful extension for SQLAlchemy, a popular Object-Relational Mapping (ORM) library in Python, designed to simplify image handling within your database. This extension provides a seamless way to associate and manage image files associated with your SQLAlchemy models.

How To Install Sqlalchemy-Imageattach?

Below, are the step-by-step of How To Install Sqlalchemy-Imageattach.

Step 1: Create a Virtual Environment

First, create the virtual environment using the below commands

python -m venv env 
.\env\Scripts\activate.ps1

Step 2: Install SQLAlchemy-ImageAttach

To get started, you need to install SQLAlchemy-ImageAttach using pip. Open your terminal or command prompt and run the following command:

pip install sqlalchemy-imageattach

Step 3: Check the Version

To check the version of the installed sqlalchemy-imageattach library, you can use the following command in your terminal or command prompt:

pip show sqlalchemy-imageattach

Check the Installation Using Code

Example : In this example, provided code defines a SQLAlchemy model BlogPost with columns id, title, and content, creates a SQLite database named ‘example.db’, and initializes a session for database operations.

The code sets up the database schema and initializes a session, preparing it for subsequent database interactions such as inserting, querying, or updating data in the ‘blog_posts’ table. The output will be a silent execution without errors, indicating the successful setup of the database and session.

Python3

from sqlalchemy import create_engine, Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker

# Define the Base object
Base = declarative_base()

# Define your model class
class BlogPost(Base):
    __tablename__ = 'blog_posts'

    id = Column(Integer, primary_key=True)
    title = Column(String)
    content = Column(String)

    # Add any other columns or relationships here

# Replace 'sqlite:///example.db' with your desired database connection string
DATABASE_URL = 'sqlite:///example.db'

try:
    engine = create_engine(DATABASE_URL)
    Base.metadata.create_all(bind=engine)

    Session = sessionmaker(bind=engine)
    session = Session()

    # Your code using the session goes here

except Exception as e:
    print(f"An error occurred: {e}")

finally:
    # Ensure that the session is closed, regardless of success or failure
    if session:
        session.close()

Output :

<ipython-input-16-8690c5d918f1>:6: MovedIn20Warning: The ``declarative_base()``
 function is now available as sqlalchemy.orm.declarative_base(). (deprecated since: 2.0) 
(Background on SQLAlchemy 2.0 at: https://sqlalche.me/e/b8d9)
  Base = declarative_base()

Code Will succesffully run and show the output . However, since there’s no actual data insertion or query operations in the code, there won’t be any visible output.
