-
-
-Here's a breakdown of the code:
-
-
-
-3. Inside the `log_activity` function, the start time is recorded using `datetime.now()`.
-
-
-
-
-
-8. The `ActivityLog` instance is added to the database session using `db.add(activity_log)`, and the changes are committed using `db.commit()`.
-
-9. If an exception occurs during the database operation, an error message is printed (you may want to implement more robust error handling).
-
-10. Finally, the database session is closed using `db.close()`.
-
-
-To use this middleware in your FastAPI application, you need to include it in the middleware stack. You can do this by adding the following code to your `main.py` file or wherever you configure your FastAPI application:
-
-from fastapi import FastAPI
-from app.api.core.middleware.activity_tracker import log_activity
-
-app = FastAPI()
-app.middleware("http")(log_activity)
-
-
-
-Note: This example assumes that you have already defined the `ActivityLog` model in your `app.db.models` module and set up the necessary database connections and session management.

-   - `post_id`: an integer foreign key column referring to the `posts` table, which is required (`nullable=False`).
-6. We define the relationships between the `Comment` model and the `User` and `Post` models using the `relationship` function from SQLAlchemy:
-   - `user`: a one-to-many relationship with the `User` model, using the `back_populates` parameter to enable bi-directional access.
-   - `post`: a one-to-many relationship with the `Post` model, using the `back_populates` parameter to enable bi-directional access.

-   - `content`: A non-nullable `Text` column for the post content.

-   - `updated_at`: A `TIMESTAMP` column that defaults to the current time when a new row is inserted and updates to the current time whenever the row is updated.
-   - `user_id`: A non-nullable `Integer` column that acts as a foreign key referencing the `id` column of the `users` table.
-4. The `user` attribute is defined as a SQLAlchemy relationship to the `User` model, which is assumed to be defined in another file (e.g., `app/api/v1/models/users.py`). The `back_populates` parameter specifies the name of the attribute on the `User` model that should be used for the reverse relationship.
+The `author` attribute is a relationship with the `User` model (assumed to be defined elsewhere), using the `back_populates` parameter to create a bidirectional relationship. This means that each `Post` instance will have an `author` attribute that references the associated `User` instance, and each `User` instance will have a `posts` attribute that contains a list of associated `Post` instances.
 
-Note: This code assumes that you have already set up the necessary database connection and defined the `Base` class in the `app/db.py` file. Additionally, you'll need to create the `users` table and define the `User` model in a separate file (e.g., `app/api/v1/models/users.py`) to establish the relationship between posts and users.

+The endpoints use SQLAlchemy models and Pydantic schemas for data validation and serialization. The `get_current_user` dependency is used to ensure that only authenticated users can access certain endpoints (e.g., read all users, read a single user, update a user, and delete a user).
