Changes between Initial Version and Version 1 of Ticket #27824

-              initial
+              v1
 With the following model:
+```
+{{{
 from django.contrib.postgres.fields import JSONField
 from django.db import models
 …
 class Subscription(models.Model):
     inputs = JSONField()
+```
+}}}
 I'd like this query to work (assuming a inputs look like `{'first_name': '...'}`:
+```
+{{{
 Subscription.objects.filter(inputs__first_name__unaccent__icontains="...")
+```
+}}}
 But it fails with:
+```
+{{{
 django.db.utils.ProgrammingError: operator does not exist: jsonb #> text
 LINE 1: ...%' OR UPPER("subscriptions_subscription"."inputs" #> ARRAY['...
+                                                             ^
 HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.
+```
+}}}
 cecef94275118dc49a1b0d89d3ca9734e2ec9776 registered a bunch of lookups for chaining after a key transform, but unaccent wasn't included. I suggest to include it as well.
