The string you're referring to is appended to the help_text of a
ManyToManyField in django.db.models.fields.related. It's not being
set by newforms, merely inherited. You also wouldn't be seeing it if
you were using CheckboxSelectMultiple, only if the normal HTML select
widget were being used.
The only case that I'm aware of where this comes up is using the
form_for_* shortcuts. To remove the string, one option is to define
your own form class. For example:
class MyForm(Form):
categories = ModelMultipleChoiceField(Category.objects.all())
If you wish to continue using the form_for_* shortcuts, you'll need to
modify the form class before instantiating it. This may be a little
uglier, but something like:
klass = form_for_model(MyModel)
klass.base_fields['categories'].help_text = ''
would do the trick, with the caveat that any other help text the model
field may have specified gets erased too.
