This SQLAlchemy model defines a `Book` class that extends the `Base` class. It includes the following columns:
|
|
|
|
- `id`: An integer primary key with an index.
|
|
- `title`: A string column for the book title with an index.
|
|
- `author`: A string column for the book author with an index.
|
|
- `description`: A string column for the book description.
|
|
- `published_year`: An integer column for the year the book was published.
|
|
- `isbn`: A string column for the book's ISBN number, which is set as unique.
|
|
- `created_at`: A datetime column that stores the creation timestamp, defaulting to the current time.
|
|
- `updated_at`: A datetime column that stores the last update timestamp, defaulting to the current time and updating on each change.
|
|
|
|
With this model, you can query books by title and author using the indexes on those columns. The `isbn` column is set as unique to prevent duplicates. The timestamps will automatically record when a book record was created and last updated. |
