Caution Review failedThe pull request is closed. WalkthroughThe changes involve enhancements to the Telegram bot's functionality, including the addition of a new option for showing subject statistics, the introduction of a chart generation module, and new database methods for retrieving solution counts and grades by subject. Additionally, a utility function for fetching and displaying subject statistics through charts has been added. A modification in the Changes

1-8: LGTM: Imports are well-organized and relevant.The imports are logically organized, with standard library imports separated from third-party imports. All imported modules are relevant to the chart generation functionality.
11-13: LGTM: ChartType enum is well-defined.The
ChartTypeenum provides a clear and type-safe way to specify chart types. Using an enum instead of strings reduces the chance of errors and improves code readability.
1-63: Overall, the new charts.py module is well-implemented and aligns with the PR objectives.The introduction of this module enhances the Telegram bot's functionality by adding chart generation capabilities. The code is well-structured, uses appropriate libraries, and follows good coding practices. The suggestions provided in the review comments, if implemented, would further improve the robustness and efficiency of the code.
Key strengths:
- Clear and type-safe
ChartTypeenum- Well-structured asynchronous
send_chartfunction- Appropriate use of seaborn and matplotlib for chart generation
Areas for potential improvement:
- Optimizing file I/O in
send_chart- Enhancing error handling across all functions
- Making chart parameters more dynamic in
prepare_hist_chartOverall, this is a solid addition to the project that will provide valuable visualization capabilities for the Telegram bot.

80-80: Approve the change, but verify its impact on the codebase.The modification of
related_namefrom "students" to "solutions" is a good improvement. It better reflects the relationship betweenSubjectTaskandSolutionmodels.However, this change might affect existing code that relies on the old
related_name.Please run the following script to check for any occurrences of the old
related_nameusage:If the script returns any results, those occurrences will need to be updated to use
solutionsinstead ofstudents.tgbot/misc/database.py (2)
108-113: 🛠️ Refactor suggestionImprove efficiency and handle potential null grades
The method logic is correct, but there are opportunities for improvement:
Efficiency: For large datasets, retrieving all solutions before extracting grades could be memory-intensive and slow.
Null Handling: The method doesn't account for the possibility of null grades, which could lead to errors if grades can be null in your database schema.
Consider applying the following changes to address these issues:
async def get_grades_by_subject(self, subject: Subject) -> list[int]: - solutions = await self.solution.filter( - subject_task__subject=subject - ).all() - return [solution.grade for solution in solutions] + return await self.solution.filter( + subject_task__subject=subject, + grade__isnull=False + ).values_list('grade', flat=True)These changes will:
- Improve efficiency by only retrieving the grade values directly from the database.
- Exclude any null grades from the result set.
To ensure these changes don't introduce any regressions, please run the following verification script:
#!/bin/bash # Description: Verify the usage of get_grades_by_subject method # Test: Check if the method is used correctly elsewhere in the codebase rg --type python -A 5 "get_grades_by_subject" # Test: Verify that the return value is treated as a list of integers rg --type python "get_grades_by_subject.*\s*=\s*" -A 3
94-106:⚠️ Potential issueImprove error handling and efficiency, and fix type hint
The method logic is sound, but there are a few areas for improvement:
Error Handling: The method doesn't handle the case where there are no students, which could lead to a division by zero error.
Efficiency: For large datasets, making separate database queries for each task's solutions could be inefficient.
Type Hint: The return type hint suggests int values, but the actual values are floats.
Consider applying the following changes:
async def get_count_solutions_by_subject( self, subject: Subject -) -> dict[str, int]: +) -> dict[str, float]: students = await self.student.filter(subjects=subject).count() tasks = await self.subjecttask.filter(subject=subject).all() stats = {} if students: - for task in tasks: - solutions = await self.solution.filter( - subject_task=task - ).count() - stats[task.name] = solutions / students + task_ids = [task.id for task in tasks] + solution_counts = await self.solution.filter(subject_task_id__in=task_ids).values('subject_task_id').annotate(count=Count('id')) + solution_dict = {sc['subject_task_id']: sc['count'] for sc in solution_counts} + for task in tasks: + stats[task.name] = solution_dict.get(task.id, 0) / students return statsThese changes will:
- Prevent division by zero when there are no students.
- Improve efficiency by fetching all solution counts in a single query.
- Correct the return type hint to reflect the actual float values.
To ensure these changes don't introduce any regressions, please run the following verification script:

198-198: LGTM: Correct addition to theutilsdictionary.The
subject_statsfunction has been properly added to theutilsdictionary, maintaining consistency with the existing pattern.tgbot/handlers/teacher.py (1)
151-151: LGTM! Verify implementation and update documentation.The addition of the "Show stats" option is consistent with the existing structure and aligns with the introduction of subject statistics functionality mentioned in the PR summary.
To ensure the completeness of this feature:
- Verify that the "subject_stats" functionality is implemented elsewhere in the codebase.
- Update any relevant documentation to reflect this new option for teachers.
Run the following script to check for the implementation of the "subject_stats" functionality:
If the implementation is not found, consider opening an issue to track the implementation of this feature.
