This PR adds support for the
empty_value
kwarg that was added toforms.CharField
in Django 1.11.On Django < 1.11, form fields that inherit from
forms.CharField
set an empty string for values that are inself.empty_values
. On Django >= 1.11, form fields that inherit fromforms.CharField
setself.empty_value
for values that are inself.empty_values
. This means all of the fields now support theempty_value
kwarg even when it'sNone
.The downside to this change is that form fields that inherit from
forms.CharField
will need to use theEmptyValueCompatMixin
until we drop support for Django < 1.11.Related #294 #295
Closes #297
