Django-filter: MultipleChoiceFilter with empty square brackets

[art1415926535]

Can I create a PHP style MultipleChoiceFilter field?
?field[]=var1&field[]=var2

That's the default.

The default is ?field=var1&field=var2 not ?field[]=var1&field[]=var2.

Ah, I see... One way: You could use custom widget to affect the input rendering (to add the [] to the name attribute)

You'll have to decide if it's what you want though:

>>> from django.http.request import QueryDict
>>> GET = QueryDict('field[]=var1&field[]=var2')
>>> GET
<QueryDict: {'field[]': ['var1', 'var2']}>

(You end up with the [] on the field name for the incoming data too.)

There is also the undocumented QueryArrayWidget.

Ah, yes. Well done! There's already a widget. Great.

(I was sure we'd had this conversation before... 🙂)
