Description (last modified by thewamz)

In a django form, when I set a value for the empty_label parameter, a TypeError is raised. TypeError: init() got multiple values for keyword argument 'empty_label'

field_name = forms.ModelMultipleChoiceField(queryset=MyModel.objects.all(), empty_label="Select something")

Hello
In version 3.8 of module forms line 1315 , The class ModelMultipleChoiceField.__init__ calls super().__init__ with empty_label = None. This a real bug easy to correct.

Please don't reopen closed ticket. This is not a bug, ModelMultipleChoiceField doesn't support empty_label (see ​docs).
