#34648 closed Bug (duplicate)

`get_prep_value` now being called for JSONField

Description

In #34539, a change was made in 4.2.2 which I think causes a regression in the expected/normal behaviour of JSONField. I ought to point out that I have reviewed the discussion in #34539 but I am not sufficiently knowledgeable to say if/how valid the arguments there are.

The behaviour change is in an add-on Django app called social-django, which sets a JSONField called extra_data and then save()s the model instance here:

https://github.com/python-social-auth/social-app-django/blob/8d0a2052d1b22a899454571c62237d23aa25af97/social_django/storage.py#L24

On the stack, I have the frames show in the attachment "stack frame", and the important point is that when I enter the two lines of code added in #34539, the value is a dict, but is flattened into a string by the new code. The result is that the database JSONField has the saved string instead of the dict as expected. I believe that to be incorrect.

Please advise.
