django.git/django/db/backends/sqlite3/base.py, branch 3.1.6

[3.1.x] Fixed #31836 -- Dropped support for JSONField contains and contained_by lookups on SQLite.

2020-07-28T11:08:19Z

The current implementation works only for basic examples without supporting nested structures and doesn't follow "the general principle that the contained object must match the containing object as to structure and data contents, possibly after discarding some non-matching array elements or object key/value pairs from the containing object". Backport of ba691933cee375195c9c50f333dd4b2a3abbb726 from master.

Fixed #12990, Refs #27694 -- Added JSONField model field.
