I think using ArrayField as a many choices field would be awesome.
Passing choices to ArrayField works fine with MultipleChoiceField on the
form.
But calling get_foo_display return a TypeError: unhashable type: 'list',
maybe this method need to check if the field is an ArrayField it can
return a string representation of the choices separated by comma.
{{{#!python
class Example(models.Model):
CHOICES = (
(1, 'value1'),
(2, 'value2'),
(3, 'value3'),
)
multi_choices_array = ArrayField(
base_field=models.IntegerField(),
choices=CHOICES,
)
example = Example.objects.create(multi_choices_array= [1, 2])
example.get_multi_choices_array_display()
# Will raise a Type Error exception
