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, ) # Adding this method will show the values def multi_choices_array_display(self): result = '' choices = dict(self.CHOICES) for index, value in enumerate(self.multi_choices_array): result += ""{0}"".format(choices[value]) if not index == len(self.multi_choices_array) - 1: result += ', ' return result example = Example.objects.create(multi_choices_array= [1, 2]) example.get_multi_choices_array_display() # Will raise a Type Error exception example.multi_choices_array_display() # Will print 'value1, value2' }}}",New feature,closed,contrib.postgres,dev,Normal,fixed,,chedi,Accepted,1,0,0,0,0,0
