-------------------------------------+-------------------------------------
The `django.db.models.FileField` currently allows only to store a single
file URL.
This behavior seems outdated considering that `input[type=file]` supports
a `multiple` attribute, which is supported by all major Browsers.
See: https://www.w3schools.com/tags/att_input_multiple.asp
I would suggest to have a similar attribute on the database field itself,
as well as on the form field and widget.
The major point for discussion would be how to store the data. The easiest
would be to coma separate the paths in a single char field. The major
concern here would be the lack of atomicity. For databases like Postgres I
would be sensical to use the `ArrayField` as an underlying structure.
Another way for serialisation would be the use of JSONs in a char field.
All solutions based on a text or char field have an issue related to the
compatibility with the current `FileField` which is limited to 100
characters. The type would need to be migrated to a text type or the
length would need to be increased. The latter options bares the question
to which point.
Another approach would be to defer the storage issue and only provide
support for multiple files on form level.
This would mean to add a `multiple` attribute to the form field and
widget. Users would be able to create forms with multiple files in a
single field and handle storage according to their preference.
