Возникновение ошибки, если входное значение равно False (булево) при загрузке листа excel через Django Form

У меня есть Django форма, через которую я загружаю лист excel в базу данных,

Здесь некоторые колонки имеют булевы поля (True/False).

В таких полях (например, block_covered, village_covered и т.д.), я хочу выдавать ошибку, такую как: "Это поле не может быть ложным", всякий раз, когда значение поля равно False(0), чтобы оно принимало только значения, которые являются True(1) и игнорировало пользователя/себя, чтобы дать ложное булево значение в качестве ввода в лист excel при загрузке, т.е. предотвратить их от загрузки листа.

Ниже приведены соответствующие файлы.

Model.py

BOOL_CHOICES = ((True, 'Yes'), (False, 'No'))
UNIT_CATEGORIES = (('ABC', 'ABC'), ('XYZ', 'XYZ'))
  
class GroupDetail(models.Model):
    unit_type = models.CharField(max_length=16, choices=UNIT_CATEGORIES)
    state_name = models.CharField(max_length=100)
    unit_name = models.CharField(max_length=100)
    districts_covered = models.BooleanField(verbose_name=_('Districts Covered "yes/no"'), choices=BOOL_CHOICES)
    block_name = models.CharField(max_length=100)
    block_covered = models.BooleanField(verbose_name=_('Block Covered "yes/no"'), choices=BOOL_CHOICES)
    village_name = models.CharField(max_length=100)
    village_covered = models.BooleanField(verbose_name=_('Village Covered "yes/no"'), choices=BOOL_CHOICES)
    number_of_group = models.PositiveIntegerField(validators=[MinValueValidator(1), MaxValueValidator(100)])
    number_of_farmers = models.PositiveIntegerField(validators=[MinValueValidator(1), MaxValueValidator(1000)])

Как это сделать?

class add_to_database(forms.ModelForm):
    village_covered = forms.BooleanField(..., required=True)
    # (repeat for other boolean fields that are required)

    class Meta:
        ...

class add_to_database(forms.ModelForm):
    ...

    def clean_village_covered(self, value):
        if not value:
            raise forms.ValidationError("Village covered must be set")
        return value
