  • Dateutil fields render issue, and consistency issue.
  • Optional validator failed when raw_data was absent

  • Add preliminary support for providing a translations object that can translate built-in validation and coercion errors.

Version 0.6

Released 2010-04-25

  • HTML is now marked as safe (using __html__) so that compatible templating engines will not auto-escape it.
  • Field._default is now Field.default.
  • All fields now have a raw_data property.

  • Added FloatField, based on IntegerField.
  • ext.appengine now supports FloatProperty and GeoPtProperty.
  • ext.sqlalchemy QueryMultipleSelectField changed to QuerySelectMultipleField.

Version 0.5

Released 2010-02-13

  • Added a BaseForm class which provides the core processing and validation functionality of Form without requiring declarative subclassing.
  • Field labels now default to a humanized field name.
  • Fields now have a short_name property which is the un-prefixed name.
  • DecimalField now rounds values for display without float coercion. See docs for details on how to format decimals.
  • ext.sqlalchemy.fields now has an additional QuerySelectMultipleField, and all fields can now support multiple-column primary keys.

  • Added ext.dateutil for flexible date-time parsing.
  • Added ext.appengine contributed by Rodrigo Moraes.
  • Added AnyOf and NoneOf validators.

Version 0.4

Released 2009-10-10

  • Fields have much greater control over input processing. Filters have been added to implement a simple way to transform input data.
  • Added fields that encapsulate advanced data structures such as dynamic lists or child forms for more powerful field composing.
  • Fields now use widgets for rendering.
  • All built-in validators have been converted to classes to clean up the code.
  • Form.auto_populate and Field.populate were renamed to populate_obj to clarify that they populate another object, not the Form or Field. This is an API breaking change.
  • Dropped support for Python 2.3.

Version 0.3.1

Released 2009-01-24

  • Several fixes were made to the code and tests to make WTForms compatible with Python 2.3/2.4.
  • Form's properties can now be accessed via dictionary-style access such as form['author']. This also has the intended effect of making variable lookups in Django templates more reliable.
  • Form and Field construction changes: Form now uses a metaclass to handle creating its _unbound_fields property, and Field construction now gives an instance of the new UnboundField class instead of using a partial function application. These are both internal changes and do not change the API.

Version 0.3

Released 2009-01-18

  • Fields are now responsible for their own validation, instead of mostly relying on Form. There are also new pre_validate and post_validate hooks on subfields, adding a great deal of flexibility when dealing with field-level validation. Note that this is an API breaking change if you have any subfields that override Field.validate. These will need to be updated to use the new hooks.
  • process_data no longer accepts the has_formdata parameter.
  • At form instantiation time, process_data will be called only once for each field. If a model object is provided which contains the property, then this value is used. Otherwise, a keyword argument if specified is used. Failing that, the field's default value is used.
  • If any form data is sent, process_formdata will be called after process_data for each field. If no form data is available for the given field, it is called with an empty list.
  • wtforms.ext.django has been overhauled, both to mirror features and changes of the Django 1.0 release, and to add some useful fields for working with Django ORM data in forms.
  • The checker keyword argument to SelectField, SelectMultipleField, and RadioField has been renamed to coerce to reflect the actual functionality of this callable.

Version 0.2

Released 2009-01-13

  • We have documentation and unit tests!
  • Fields now have a flags property which contain boolean flags that are set either by the field itself or validators being specified on a field. The flags can then be used in checks in template or Python code.
  • Changed the way fields take parameters, they are no longer quasi magic. This is a breaking change. Please see the documentation for the new syntax.
  • Added optional description argument to Field, accessible on the field as description. This provides an easy way to define e.g. help text in the same place as the form.
  • Added new semantics for validators which can stop the validation chain, with or without errors.
  • Added a regexp validator, and removed the not_empty validator in favour of two validators, optional and required. The new validators allow control over the validation chain in addition to checking emptiness.
  • Renamed wtforms.contrib to wtforms.ext and reorganised wtforms.ext.django. This is a breaking change if you were using the Django extensions, but should only require changing your imports around a little.
  • Better support for other frameworks such as Pylons.

Version 0.1

Released 2008-07-25

  • Initial release.
