Description
Attempting to json.dumps() the result of apps.get_models() leads to a TypeError:
TypeError at /uploader/select-models/ 'Designates whether this user should be treated as active. Unselect this instead of deleting accounts.' is not JSON serializable
That is because "Designates whether this user should be treated as active. ...." is not a string, but the converted representation of a django.utils.functional.lazy.<locals>proxy object. That is not JSON serializable.
Debugging this is onerous because in all respects the help text looks and acts like a string.
Note:
See TracTickets
for help on using tickets.
Django has a special JSON encoder to dumps typical Django data: https://docs.djangoproject.com/en/2.2/topics/serialization/#djangojsonencoder
I don't see what we could do to prevent your bad debugging session, but if you have ideas, feel free to suggest them.
