This code defines a set of CRUD (Create, Read, Update, Delete) endpoints for comments in a FastAPI application. Here's a breakdown of the functionality:
|
|
|
|
1. `create_comment` endpoint: Accepts a `CommentCreate` Pydantic model and creates a new comment in the database.
|
|
2. `get_all_comments` endpoint: Retrieves a list of all comments from the database.
|
|
3. `get_comment` endpoint: Retrieves a single comment by its ID. If the comment is not found, it raises an `HTTPException` with a 404 status code.
|
|
4. `update_comment` endpoint: Updates an existing comment by its ID. If the comment is not found, it raises an `HTTPException` with a 404 status code.
|
|
5. `delete_comment` endpoint: Deletes a comment by its ID. If the comment is not found, it raises an `HTTPException` with a 404 status code.

Note: You will need to import the required models and schemas in your application and ensure that the database connection is properly configured. |
