Download all photos and videos from your Class Dojo account

download_class_dojo_archive.py

"""
Download all ClassDojo photos and videos in your timeline.
by kecebongsoft

How it works:

1. Fetch list of items in the timeline, if there are multiple pages, it will fetch for all pages.
2. Collect list of URLs for the attachment for each item
3. Download the files into local temporary directory, and also save the timeline activity as a json file.

How to use:

1. Modify the session cookie in this script, check your session cookie by opening classdojo in browser and copy
the following cookies: dojo_log_session_id, dojo_login.sid, and dojo_home_login.sid
2. Run this script and wait for it to finish.

If error happens:

1. I ran this script in windows, make sure your path is correct if you are on linux
2. Make sure "classdojo_output" directory exists in the same folder as this script
3. Make sure you have a correct session cookies set in this script.
4. Make sure you can open the FEED_URL listed in this script from within your browser (assuming you can open ClassDojo website)

Hi Kate
I'm a teacher wanting to download portfolio photos from classdojo. However, calling me a novice at coding would be an understatement.
Where and how do I insert this code?
I have read your instructions above, but I am still unsure how to:

• Check my session cookies
• Run the script
  Any help would be much appreciated.
  Cheers

I just ran this and it worked great. It copies from a downloaded temp folder and has useless filenames, but you can batch rename them pretty easily.

You'll need to get your cookie id's using something like "Cookie Quick Manager" extension for Firefox.
Copy the cookie id's into the script where designated...lines 32, 33, 34.

Make sure you have python installed and install the requests module as well.
Make sure you create a subfolder where the script is located called "classdojo_output".

Run the python script: I did it on windows by opening a command prompt and change the directory to the script folder
then type "python <script name>"

I have set this up and runs, but all it will do is create the json file in the classdojo_output folder. There are no images or videos at all.

Can anybody help, my daughters account is being turned off tomorrow. Thank you!

It's best to use os.path.join() instead of using a \\ path separator. Even though, I believe a / should also work on Wintendo.

@kecebongsoft Thanks for the script. I have modified it to better suit my purpose, and introduced a NOT_BEFORE parameter to more easily keep a cache/offline-copy here. I'll try to put a bit of a CLI around it and may share it here later.

You're a savior. Thanks for this script, much appreciated :)

This is fantastic, thank you! Do you have any ideas for grabbing the comments on pictures? I can try to figure out how to get them but wanted to ask before I started from scratch.

Bravo!

Very good script indeed.
Worked as expected for me.
Thanks a lot.
