Problem Statement :
I want to develop a custom "XBlock" for edx-platform which allows the course creator to upload images, associate a text description with each image which will show up as a Slider on course content.
I have a basic slider working with some static images, however I am having some issues while uploading the images using the Xblock.Basically I think there are two ways to achieve this functionality.
Using edx's default APIs to upload the image asset and then retrieving its relative path in my xblock content. However, I am not sure how I should go about this.. Sending request on below url from cms's url.py:
url(r'^assets/{}/{}?$'.format(settings.COURSE_KEY_PATTERN, settings.ASSET_KEY_PATTERN), 'assets_handler'),
From some other sources on the internet, I figured that may be I should create a custom upload handler for my xblock which would upload the files to server.
I did try create a handler using method : 2, but I ran into the following error as soon as I upload my image using Ajax multipart/form-data.
Traceback (most recent call last):

Any hints regarding how I should approach this problem would greatly help. Thanks in advance.
