'dict' object has no attribute 'method'

[robertovergallo]

Hi Brad, thank you for your work. I'm trying to configure your scorm xblock using a scorm quiz. I know this is a work in progress and I'd like to help. When I submit the answer, the local js tells perfectly the score, but I see a 500 error in the network console. Is it the same problem you face? Thanks Roberto

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 500 page.

It seems solved by putting the whole content of scorm_commit in scorm_set_value Now I can see the SCORM apis setting successfully the variables in the Dict. Unfortunately, user's selections get not selected in the quiz GUI when he returns to the quiz

Hello! This is just to let you know that this issue is not being ignored. I'm just returning from a vacation, and have to catch up with my day-job work first, though, but I will investigate this as soon as I can. In the mean-time, please keep experimenting and let me know if you find any other problems.

This project is still in very early stages, but especially if there are people out there who want to use it, I would love to keep trying to make it work!

I spent some time on this this evening, but to be honest I haven't had time to work with this code for a while, and I have not had much insight except to remember that when I was last working on it I'd encountered some kind of roadblock around the way xblocks store data not being easily compatible with the way SCORM models it.

In the mean-time, @ihowson has been working more recently on his own fork of this xblock, which is focused on xAPI support but may also support SCORM. You might wish to look there and see if you get better results.

Hi Brad! Thank you for your kind replies! I've also tried ihowson's fork, but it asked me for Tin Can API files which I don't have and don't need at all right now. I like your code because it's very clean. I'm going to experiment more in the next days, if I have news I'll let you know. Bye! Roberto
