Formulator changes
1.6.2
Bugs Fixed
- Fixed bug which caused validation of listfields to throw an
exception when a list of strings was used as the value of
<items> and one of the elements was 2 characters long.
- Formulator should now work again in Zope 2.7; Zope 2.7 has a
change to the way it retrieved the character set it used to to
display the ZMI. This interacted badly with the recent changes
in Formulator to support unicode.
- Added 'refresh.txt'. I don't consider it a bug if this doesn't
work for you though -- I'm not using it. :)
- XML representation of method-values attributes did not work.
- python 2.1.3 compatibility: boolean values like "required"
are translated to int on XML serializations/deserialization.
The last two fixes are due to Sebastien Robin
- render_hidden of DateTimeField's and fields allowing multiple
selections did not lead to something useful for validation.
- RadioField and ListField did not display the text but the value
in render_view.
Other
- Whitespace normalization in sources.
1.6.1
Bugs Fixed
- Adding Fields to empty Groups had not been possible.
- ZMI "Order" tab of an empty form did raise an exception.
1.6.0
Features Added
- FileSystemSite/DirectoryView improvements:
* XML filesystem representation of Formulator forms can now
also be used with CMF (if FileSystemSite is not installed).
* FSForm gets automatically registered with the directory
view system if CMF or FileSystemSite is installed.
- Infrastructure for Validators not to get taken into account in
validation procedures (need_validate).
- A new label field. Doesn't participate in validation. It shows
its text as a label in the form.
- Unicode mode. A form can now be put in 'unicode mode', which
means it stores all its textual data as unicode strings. This
allows for easier integration with Zope systems that use unicode
internally, such as Silva.
- Disabling of fields. A field can now be disabled from being
displayed or validated by unchecking the 'Enabled' validator
property. This can be done dynamically as well using TALES
overrides.
Bugs Fixed
- The css_class value of a DateTime field had been ignored. It
is now properly passed down to its subfields, so all subfield
elements are rendered with the given css_class value.
1.5.0
Features Added
- Added ProductForm, which provides a wrapping around
Formulator.BasicForm, allowing it to be created inside a
product but used outside it.
- Allow turning off of XML prologue section.
- Optimization of TALESMethod by caching compiled expression.
This speeds SilvaMetadata indexing up by a lot if a fallback
on default is made, especially in the case of Python
expressions, as it avoids lots of compilation overhead.
- Extra attribute defined for list/multicheckbox/radio fields
called 'extra_item', which allows setting HTML attributes to
individual list item/checkbox/radio button.
Bugs Fixed
- XML serialization should be more consistent now; field properties
are now ordered by name upon serialization.
- Allow XML export of BasicForm.
1.4.2
Bugs Fixed
- Sticky forms should now work correctly in the presence of unicode.
Encoded data is automatically converted to unicode if the information
is pulled from the REQUEST form.
1.4.1
Bugs Fixed
- It was not possible to make DateTime fields not required when
'allow_empty_time' was enabled. Fixed.
1.4.0
Features Added
- Added limited ability to output unicode for selected
fields. Only works properly in Zope 2.6.x, and the HTML pages
these forms are in need an output encoding set (such as
UTF-8, which is also Formulator's default encoding). If
'unicode' checkbox is checked Formulator will try to interpret
its input in the Form's encoding (default is UTF-8). It will
also try to display its values in that encoding. Note that
only field values and items currently work with unicode -- the
rest of the textual properties of a field are still stored as
8-bits. If you make sure that these properties are encoded as
UTF-8 (or whatever encoding you choose for the form) things
should be okay, however.
- Can now also change forms using XML (not just view it).
- DateTime fields can now optionally input AM/PM.
- DateTime fields can now optionally be set to allow time to
be left empty.
- 'whitespace_preserve' option on string type fields. If turned on,
whitespace will not be automatically stripped and will count as
input.
- 'render_view' method on fields to render the value outside a
widget.
- Added some code support used by SilvaMetadata to enable rendering
of fields with Zope's ':record' syntax.
Bugs Fixed
- Fixed a Python2.2 compatibility bug in XMLObjects.py
- DateTimeField now picks up default values from REQUEST
properly if necessary.
- XML representation of the LinkField "check_timeout" value
messed the type="float" attribute.
- Additional unit tests.
1.3.1 (2002/12/20)
Features Added
- Error messages can now be included in the XML serialization.
- Ability to encode lists as a special type in values.
Bugs Fixed
- Some more proper encodings.
- Handle case where group has no field.
- Handle DateTime field better.
1.3.0 (2002/11/26)
Features Added
- FormToXML and XMLToForm modules have functions to serialize
(most of) form to XML and read it in again (over an existing
form).
- New XML tab for forms which shows the XML serialization (no
saving option yet).
- FSForm.py uses XML serialization to provide a formulator form
version for FileSystemSite. It does not get imported by
default.
Bugs Fixed
- The email validator has an improved regular expression.
- Fix error that occured when trying to render DateTimeField as
hidden.
1.2.0 (2002/03/06)
Features Added
- Changes to exception infrastructure so errors can now be
imported and caught in a through the web Python script. Example::
from Products.Formulator.Errors import ValidationError, FormValidationError
- added __getitem__ to Field so instead of using get_value() you can
also do this in Python: form.field['title'], and in ZPT you can
use this in path expressions: form/field/title
- made a start with Formulator unit tests; some validators get
automatically tested now.
Bugs Fixed
- Removed dependencies of the name of 'Add and Edit' button to make
internationalization of the management interface easier.
- added permission to make ZClasses work a bit better (but they
still don't cooperate well with Formulator, I think. I don't use
ZClasses, so I hope to hear from this from ZClass users)
- Form's properties tab now visible and form tabs stopped
misbehaving.
- Lists and such should handle multiple items with the same value
a bit better, selecting only one.
- the LinkField now checks site-internal links better.
1.1.0 (2001/10/26)
Bugs Fixed
- Fixed bug in form settings tab.
- the LinkField now checks site-internal links better.
1.0.9 (2001/10/05)
Features Added
- New TALES tab for fields as a more powerful Override tab;
PageTemplates needs to be installed to make it work.
- added 'name' attribute for forms. When the form header is
rendered, name will be an attribute. This can be used to
control forms with Javascript.
Bugs Fixed
- More compliance with Zope product guidelines; moved dtml
files from www dir to dtml dir.
- Fixed a bug in that form titles would not work. Forms now have
titles, and you can change them in the settings tab. (Formulator
does not use the title property internally though)
1.0.1 (2001/07/27)
Bugs Fixed
- Fixed bug with renaming groups. Previously, renamed groups were not
properly stored in the ZODB.
- Made MultiSelectionValidator (used by MultiListField among others)
deal better with integer values.
- Hacked around CopySupport changes in Zope 2.4.0; renames work
again now.
1.0 (2001/07/10)
Features Added
- New field: RawTextAreaField. A textarea field that doesn't
do a lot of processing on the text input.
- Checked in BSD license text.
Bugs Fixed
- Fixed minor bug in year handling of DateTimeField.
- Now hidden fields also take text from 'extra' property.
- Fixed bug in MultiItemsWidget; would not deal with only a
single item being selected.
0.9.5 (2001/06/27)
Features Added
- Added FileField (with browse button). Can be used to upload
files if form is set to multipart/form-data.
- Added LinkField for URLs.
- Made ListField and RadioField more tolerant of integer
(and possibly other) values, not only strings.
- Made ListField and RadioField happy to deal with non-tuples too in the
items list. In this case, the item text and value will be identical.
- Refactored ListWidget and RadioWidget so they share code; they both
inherit from SingleItemsWidget now.
- Added LinesField to submit a list of lines in a textarea.
- Added MultiListField and MultiCheckBoxField, both use new
MultiItemsWidget and MultiSelectionValidator.
- Added EXPERIMENTAL PatternField.
0.9.4 (2001/06/20)
Features Added
- Added API docs for Form, BasicForm and ZMIForm.
- Renamed the confusingly named PythonForm and PythonField to
ZMIForm and ZMIField, as they are used from the Zope Management
Interface and not from Python.
- Added render() method to form for basic form rendering.
- Added Formulator HOWTO document.
Bugs Fixed
- Removed some validation code that wasn't in use anymore (items_method).
- Removed 'has_field_id' in Form as this duplicated
the functionality of 'has_field'.
- Turned <br> in Python sources to <br /> for XHTML compliance.
- Tweaked radiobutton; text is now closer to the button itself,
different buttons are further apart.
0.9.3 (2001/06/12)
Features Added
- added RadioField for simple display of radio buttons.
- added action, method and enctype property to form settings.
These are displayed using the special form.header() and form.footer()
methods.
- added override tab to allow all properties to be overridden by
method calls instead. 'items_method' in ListField went
away.
- added ability to display DateTimeFields using drop down lists
instead of text input. Added some other bells and whistles to
DateTimeField. Changed some of the inner workings of composite
fields; component fields are now unique per field instance
instead of shared between them.
- is_required() utility method on field to check whether a field
is required.
- some internal features, such the ability to have a method
called as soon as a property has changed.
Bugs Fixed
- Fixed typos in security assertions.
- use REQUEST.form instead of REQUEST where possible.
- display month and day with initial zero in DateTimeField.
- Fixed bug in validate_all_to_request(); what can be validated
will now be added to REQUEST if possible, even if a
FormValidationError is raised.
0.9.2 (2001/05/23)
Features Added
- Ability to rename groups, including the first 'Default' group.
- Improved support for sticky forms; form.render() can now
take an optional second argument, REQUEST, which can come
from a previous form submit. Even unvalidated fields will
then be sticky.
- fields can call an extra optional external validation
function (such as a Python script).
- New alternate name property: the alternate name is added to
the result dictionary or REQUEST object after validation. This
can be useful to support field names which wouldn't be valid
field names, which can occur in some locales.
- New extra property; can be used to add extra attributes to
a HTML tag.
- Some IntegerField properties can now be left empty if
no value is required, instead of having to set them to 0.
- Merged functionality of RangedIntegerField into IntegerField.
RangedIntegerField is not addable anymore, though supported
as a clone of IntegerField for backwards compatibility. Leaving
'start' and 'end' empty in the new IntegerField will mean those
checks will not be performed.
Bugs Fixed
- Added more missing security declarations.
- html_quote added in various places to make fields display
various HTML entities the right way.
0.9.1 (2001/05/13)
Features Added
- Widgets now have a 'hidden' property. If set, the widget is
drawn as a 'hidden' field. 'hidden' fields do get validated
normally, however.
- Changed API of Widget and Validator slightly; render() and
validate() methods now take an extra 'key' argument indicating
the name the field should have in the form. This is necessarily
to handle sub fields of composite fields.
- Added EmailField and FloatField.
- Added some infrastructure to support 'composite fields'; fields
composed out of multiple sub fields.
- Added DateTimeField, the first example of a composite field
(field made of other fields).
Bugs Fixed
- General code cleanups; removed some unused methods.
- Fixed security assertion for validate_all_to_request() method.
- MethodFields now check whether they have 'View' permission to
execute listed Python Script or DTML Method.
- RangedInteger is now < end, instead of <=, compatible with the
documentation.
