That won't work.

objectitem.data is a reference to a list of dicts

changing something inside, doesn't signal the model that it's data has changed, as the reference doesn't change.

 

You need to manipulate the data as it's own structure, then assign it:

 

data = objectitem.data

data[0]['processed'] = True

objectitem.data = data

objectitem.save()

 

If the above don't work:

objecitem.save(force_update=True, update_fields=('data',))
