Download all assignment data!

Post date: Jan 14, 2014 8:8:36 PM

Assignment managers (both instructors, and TAs listed as observers) can now download all assignment data! 

There are two steps required.  

First, you need to download a Json file that contains a description of the assignment. 

You can do so by going to the assignment, and selecting Download Assignment Data. 

Second, you need to get the Python CrowdGrader assignment downloader from GitHub.

You can then run the downloader via:

./download_assignment.py <assignment_file.json> <destination_directory>

This will produce a directory in <destination_directory>, and it will create one sub-directory for each submission.  In the sub-directory for each submission, you will find the submission metadata, the submission text, the reviews if any, and the files that have been uploaded.  The format should be self-explanatory. 

The reason you have to go through this two-step process is that an assignment can consist of a very large amount of data (up to several GB for some assignments, depending on the files that have been uploaded).  Therefore, downloading an entire assignment can take a long time, and cannot be performed as a single download. 

The downloader code is supplied with a MIT license, so please feel free to improve it and to share back your improvements.
