Ease customizing the JSONField widget

[Charlie Denton]

On normal form fields, one can customise the widget with an attribute of the field. eg:

class CoffeeField(django.forms.CharField):
    widget = CoffeeWidget

>>> CoffeeField().widget
<CoffeeWidget object at 0xc0ffeec0ffee>

However, with contrib.postgres.forms.jsonb.JSONField this doesn't work. Instead, once must override __init__() or pass widget in as a kwarg.

Luckily, it's pretty easy to fix, and I've almost completed writing a patch. I'll link to it here once done.

Thank you for accepting the patch, charettes :)

I'm curious what the policy is here -- will this be backported into existing versions, or will this become available when 1.10 comes out?

In f2c0eb19:

Fixed #26748 -- Allowed overriding JSONField's widget with an attribute.

This will be in 1.11, see our ​supported versions policy for details on the backport policy.
