Re: Form Validation Error: 'No' value must be either True or False.

Another bit of info, just in case anyone is currently looking at this..

The error is coming from /usr/local/lib/python2.7/dist-packages/django/db/models/fields/__init__.py

class BooleanField(Field):

    empty_strings_allowed = False

    default_error_messages = {

        'invalid': _("'%s' value must be either True or False."),

    }

    description = _("Boolean (Either True or False)")

    def __init__(self, *args, **kwargs):

        kwargs['blank'] = True

        if 'default' not in kwargs and not kwargs.get('null'):

            kwargs['default'] = False

        Field.__init__(self, *args, **kwargs)

    def get_internal_type(self):

        return "BooleanField"

    def to_python(self, value):

        if value in (True, False):

            # if value is 1 or 0 than it's equal to True or False, but we want

            # to return a true bool for semantic reasons.

            return bool(value)

        if value in ('t', 'True', '1'):

            return True

        if value in ('f', 'False', '0'):

            return False

        msg = self.error_messages['invalid'] % value

        raise exceptions.ValidationError(msg)

So it's failing validation because it's seeing the field as a BooleanField, when I quite obviously have set it as a CharField.

I'm absolutely stuck.

Hi all. Really really confused by this one. Can someone show me where I'm being stupid please?

Standard Django 1.5.1 app with MySQL. Trying to save to a VARCHAR(3) column with a forms.CharField form field and a models.CharField model field.

When I try to save the form I get this validation error:

This is the MySQL column definition:

`customers_impacted` varchar(3) DEFAULT NULL,

This is from forms.py (it's a ModelForm):

YES_NO = (

        ('No', 'No'),

        ('Yes', 'Yes'),

        )

customers_impacted = forms.CharField(widget=forms.Select(choices=YES_NO),max_length=3)

This is from models.py:

customers_impacted = models.CharField(max_length=3)

The field was originally a BooleanField but I changed it to CharField and I can't see anywhere it could still be getting the Boolean / True / False info from.

Strangely, it works fine using the development server, but this error happens when using Apache + mod_wsgi. I've rebooted the server, restarted everything, tried changing collation etc.

Could anyone suggest anything? Any extra logging etc I can turn on somewhere to show where the validation is failing?

Thanks.

Darren (confused)
