Description
#34539 introduced a change to 4.2.2 which seems to have broken the social_django code I use. AFAIK, the old behaviour was present well before the apparent regression noted in #34539 between 4.1 and 4.2.
I'm not especially knowledgeable about the issues debated above, but here is what I see. First, social_django sets a JSONField extra_data and then saves the value here:
Second, on the stack, I have the frames shown in the attachment "stack frames". The important point is that when I enter the two new lines of code added in #34539, value is a dict, but the value is flattened into a string by the new code.
The result is that the database JSONField has the saved string while previously, the dict was saved as expected. I believe that to be incorrect.
(Perhaps the intent here was to only have this change apply to subclasses of JSONField?)
Advice appreciated.
