Comment (by girzel):
I had no idea! It works perfectly. Consider this a documentation bug
report, then. :)
First, it might be nice to note this requirement here:
https://docs.djangoproject.com/en/1.7/ref/forms/fields/#django.forms.ModelMultipleChoiceField
And just say that, if you want to hide the input, you have to use
MultipleHiddenInput. Second, the HiddenInput widget documentation (which I
did look at) says this:
> Note that there also is a MultipleHiddenInput widget that encapsulates a
set of hidden input elements.
"A set of hidden input elements" is not at all how I was thinking of a
ManyToManyField. Perhaps something like "that is used to hide inputs that
return multiple values". Or, "that return a list of values". Or...
What would probably be nicest is to have a way to say
`fields["authors"].hidden = True`, and let Django figure it out. That
would be a much larger project, however.
Also I found this intriguing, though incomprehensible:
https://docs.djangoproject.com/en/1.7/releases/1.7.3/#database-denial-of-
service-with-modelmultiplechoicefield
Thanks very much for your help.
