I'm pleased to announce FormEncode 0.3. What is it? -----------
FormEncode is a package for form validation and conversion. It also includes modules for parsing, filling, and extracting metadata from HTML forms. It features robust conversion both of incoming and outgoing data, attention paid to helpful error messages, and a wide variety of pre-build validators. It also supports composition of validators, and validating structured data, including nested and repeating form elements. FormEncode is being used in several projects, including Subway, TurboGears, and SQLObject. Where is it? ------------ Website and docs: http://formencode.org Download: http://cheeseshop.python.org/pypi/FormEncode What has changed? ----------------- >From the news file: * Allow errors to be inserted automatically into a form when using ``formencode.htmlfill``, when a ``<form:error>`` tag isn't found for an error. * Added ``if_key_missing`` attribute to ``schema.Schema``, which will fill in any keys that are missing and pass them to the validator. * ``FancyValidator`` has changed, adding ``if_invalid_python`` and ``validate_python`` options (which also apply to all subclasses). Also ``if_empty`` only applies to ``to_python`` conversions. * ``FancyValidator`` now has a ``strip`` option, which if true and if input is a string, will strip whitespace from the string. * Allow chained validators to validate otherwise-invalid forms, if they define a ``validate_partial`` method. The credit card validator does this. * Handle ``FieldStorage`` input (from file uploads); added a ``formencode.fieldstorage`` module to wrap those instances in something a bit nicer. Added ``validators.FieldStorageUploadConverter`` to make this conversion. * Added ``StringBoolean`` converter, which converts strings like ``"true"`` to Python booleans. Bugfixes ~~~~~~~~ * A couple fixes to ``DateConverter``, ``FieldsMatch``, ``StringBoolean``, ``CreditCardValidator``. * Added missing ``Validator.assert_string`` method. * ``formencode.htmlfill_schemabuilder`` handles checkboxes better. * Be a little more careful about how ``Invalid`` exceptions are created (catch some errors sooner). * Improved handling of non-string input in ``htmlfill``. Experiments ~~~~~~~~~~~ * Some experimental work in ``formencode.formgen``. Experimental, I say! * Added an experimental ``formencode.context`` module for dynamically-scoped variables. -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
