forms.RegexField

class RegexField(**kwargs) [source]

• Default widget: TextInput
• Empty value: '' (an empty string)
• Normalizes to: A Unicode object.
• Validates that the given value matches against a certain regular expression.
• Error message keys: required, invalid

Takes one required argument:

regex

A regular expression specified either as a string or a compiled regular expression object.

Also takes max_length, min_length, and strip, which work just as they do for CharField.

strip

Defaults to False. If enabled, stripping will be applied before the regex validation.
