The horizon.utils.fields Module

class horizon.utils.fields.IPField(*args, **kwargs)

Bases: django.forms.fields.Field

Form field for entering IP/range values, with validation. Supports IPv4/IPv6 in the format: .. xxx.xxx.xxx.xxx .. xxx.xxx.xxx.xxx/zz .. ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff .. ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff/zz and all compressed forms. Also the short forms are supported: xxx/yy xxx.xxx/yy

horizon.utils.fields.version

Specifies which IP version to validate, valid values are 1 (fields.IPv4), 2 (fields.IPv6) or both - 3 (fields.IPv4 | fields.IPv6). Defaults to IPv4 (1)

horizon.utils.fields.mask

Boolean flag to validate subnet masks along with IP address. E.g: 10.0.0.1/32

horizon.utils.fields.mask_range_from

Subnet range limitation, e.g. 16

That means the input mask will be checked to be in the range

16:max_value. Useful to limit the subnet ranges

to A/B/C-class networks.

IPField.clean(value)

IPField.invalid_format_message = u'Incorrect format for IP address'

IPField.invalid_mask_message = u'Invalid subnet mask'

IPField.invalid_version_message = u'Invalid version for IP address'

IPField.max_v4_mask = 32

IPField.max_v6_mask = 128

IPField.validate(value)

class horizon.utils.fields.SelectWidget(attrs=None, choices=(), data_attrs=(), transform=None)

Bases: django.forms.widgets.Select
