Thank you for your hard work on this project! 😊 While your implementation meets many of the task requirements, there are a few critical issues that need to be addressed before we can approve the pull request:
-
Response Handling in
patch_movie: The function currently raises anHTTPExceptionwith a status code of 200, which is incorrect. Instead, it should return a JSON response with a success message and a status code of 200. This is crucial for ensuring the API behaves as expected. -
Data Integrity in Relationships: There are several areas where the handling of related data (genres, actors, languages) could lead to data integrity issues. Specifically, the current checks might not account for partial matches, which could result in duplicate entries or missing data. It's important to ensure that only missing related entities are created.
-
Error Handling and Logging: Consider improving error handling by logging exception details. This will aid in debugging and provide better error tracking.
Please address these issues to ensure the functionality and integrity of the code. Once these are resolved, we can proceed with the approval. Keep up the great work, and don't hesitate to reach out if you need any assistance! 🚀

The check for genres_data being empty might not be sufficient if some genres exist and some don't. Consider handling partial matches by creating only the missing genres.

Similar to genres, the check for actors_data might not account for partial matches. Ensure that only missing actors are created.

The same issue applies here for languages_data. Handle cases where some languages exist and others need to be created.

Consider logging the exception details for better debugging and error tracking, rather than just raising a generic HTTPException.

The patch_movie function should return a success response, not raise an HTTPException. Consider returning a JSON response with a success message instead.

The date field in MovieCreateSchema allows dates up to one year in the future. Ensure this aligns with your application's requirements for movie release dates.

Review Summary
Great job on implementing the code! 🎉 While the overall structure and functionality are well thought out, there are several critical issues that need attention to ensure the application runs smoothly and maintains data integrity. Here are the key points to address:
-
Response Handling in
patch_movie: The function should return a JSON response with a success message and a status code of 200 instead of raising anHTTPException. This change is crucial for ensuring the API behaves as expected. -
Data Integrity in Relationships: The current logic for handling genres, actors, and languages may lead to duplicates if some entities already exist. Modify the logic to create only the missing entities to prevent data integrity issues.
-
Error Handling and Logging: Improve error handling by wrapping database operations in try-except blocks and logging exceptions. This will aid in debugging and provide better error tracking.
-
Session Binding in SQLite: Bind the session directly to
sqlite_engineinstead ofsqlite_connectionto avoid issues with transaction management. -
Path Construction in
settings.py: Correct the syntax error in thePATH_TO_MOVIES_CSVpath construction to ensure it points accurately to theimdb_movies.csvfile. -
Migration Configuration: Ensure the
run_migrations_offlinefunction is correctly configured to use a URL instead of an engine for offline migrations.
These improvements will enhance the robustness and maintainability of your code. Keep up the good work, and use this feedback to refine your skills further. Remember, addressing these issues will not only improve this project but also help you avoid similar problems in the future. Happy coding! 🚀

There is a syntax error in the path construction for PATH_TO_MOVIES_CSV. The path should not end with a slash, as it is not a directory. Ensure the path is correctly constructed to point to the imdb_movies.csv file.

The current logic for handling genres, actors, and languages may lead to data integrity issues. If any of these entities partially exist, the create_objects function will create duplicates for the non-existing ones. Consider modifying the logic to only create missing entities.
| if not actors_data: | ||
| actors_data = create_objects(movie.actors, ActorModel, db) |

Similar to the genres handling, the logic for actors may lead to duplicates if some actors already exist. Ensure that only missing actors are created.

The logic for handling languages can also lead to duplicates if some languages already exist. Modify the logic to create only the missing languages.

Consider adding logging for the SQLAlchemyError to improve error tracking and debugging.

The update_movie function correctly returns a success message upon successful update. Ensure consistency in response format across different endpoints.

The normalize_country validator correctly normalizes the country code to uppercase. Ensure that the input data is consistent with this format.

The normalize_list_fields validator capitalizes the first letter of each word in the list fields. This is a good practice to ensure consistency in data formatting.

Ensure that the next_page link is correctly formatted and matches the expected URL structure. This is crucial for verifying pagination functionality.

The test for duplicate movie creation correctly checks for a 409 conflict error. Ensure that the error message is consistent with the expected format.
