Thank you for your input. I tried what you suggested by first just
trying to loop through the data like so:
"
test_output = 0
for obj in serializers.deserialize('json', gantt_data)['ganttgroups']:
test_output = test_output + 1
"
This generated the following error:
"'generator' object is unsubscriptable"
I tried changing it slightly, moving "['ganttgroups']" inside the
brackets, to this:
"
test_test_output = 0
for obj in serializers.deserialize('json', gantt_data['ganttgroups']):
test_output = test_output + 1
"
This generated the error I originally received:
"string indices must be integers"
I am just so new to this that I'm not sure where to go from here. Do
you have any other suggestions as to what I may be doing wrong?
Again, any help with this would be greatly appreciated.
