python - Django RegexValidator Not working as expected -

i'm stuck regexvalidator class.

i'm trying allow input of defined html(p, ul, li) tags in character field. next regex need i'm having difficulty implementing it.

<\/?(?!p|ul|li)[^/>]*>

i'm trying implment django model in next way:

description = models.charfield(max_length = 255, validators=[ regexvalidator( regex = r'<\/?(?!p|ul|li)[^/>]*>', message = 'disallowed tags', code = 'disallowed_tags', ), ], )

i'm using django 1.6. when implement above code, seems form submissions (using admin interface) fail validation.

any ideas?

thanks

do won validator , if rexep match throw error since shouldn't allowed. here more info validator.

import re django.core.exceptions import validationerror def test(val): if re.match('<\/?(?!p|ul|li)[^/>]*>', val): raise validationerror('disallowed tags') class foo(models.model): name = models.charfield(max_length = 150, validators=[test])
