# BBGradebookOrganiser
Blackboard Gradebook Organiser

## Description

**Blackboard Gradebook Organiser** is a tool for organising a downloaded gradebook with assignment submissions from [Blackboard Learn](https://en.wikipedia.org/wiki/Blackboard_Learn).
The submission files are organised per student, by extracting the student number from the submission file names and creating a directory per student. Any compressed files (.zip, .rar, .7z) are extracted into the student's directory, with any remaining files submitted individually also moved into the student's directory. Student comments from submissions are also extracted into a single text file for convenient access and review. 

### Features
- Extracts, and organises per student, the content of submitted compressed files with extensions: .zip, .rar, .7z
  - Detects invalid/corrupt files
  - Doesn't extract macOS system generated files (ignores directory *__MACOSX* inside the compressed file)
- Deletes each compressed file after successful extraction into student directory
- Organises per student any remaining individually submitted files
- Checks and extracts any comments from the student submission generated text files
- Checks if any compressed files (from the contents of the submitted compressed files) have been extracted and organised per student
  - The path of any extracted and organised compressed files will be displayed on the terminal - they need to be extracted manually

## Instructions

### Download gradebook
- Go to the course page on Blackboard
- Go to *Grade Centre -> Full Grade Centre*
- Find assignment and click on the arrow for more options, and select *Assignment File Download*
- Select all (click *Show All* at the bottom first, to display all users) and click submit to generate the gradebook zip file
- Wait for the generated download link to appear, and click to download

### Extract gradebook
- Extract the downloaded gradebook in a new directory inside *BB_gradebooks*

### Run script
- Before running the script for the first time, install the required packages 
  - `python -m pip install -r requirements.txt`
  - If running on Linux/Mac, you also need to have *unrar* installed in order to be able to extract .rar files
    - `sudo apt install unrar` for Linux
    - `brew install rar` for Mac
- Provide the name of the directory (from section *Extract gradebook* above) as an argument when running the script
  - `python organise_gradebook.py GRADEBOOK_DIR_NAME`
- While running, the script displays on the terminal information and stats about the gradebook submissions and files

### Post-run
- All submission files can be found - organised in directories per student number - in directory *BB_submissions* under the sub-directory named after the gradebook name provided when running the script
  - e.g. `python organise_gradebook.py GRADEBOOK_DIR_NAME` creates the directory *GRADEBOOK_DIR_NAME* inside *BB_submissions*
- Each student directory contains the student's extracted and individually submitted files, and the text file generated by Blackboard with the submission (which also contains any comments left by the student)
- All comments found in the gradebook are extracted in a text file in *BB_submissions*, with the gradebook name as prefix
  - e.g. *AssignmentX_comments.txt* will be created for gradebook *AssignmentX*
- Compressed files are deleted after successfully extracting and organising the contents
  - any invalid/corrupt compressed files are moved into folder *\_\_BAD\_\_* inside the gradebook directory

## Notes

The Blackboard generated name for submission files must follow the pattern:
> ANYTHING_STUDENTNUMBER_attempt_DATETIME_FILENAME
