deform 0.9.5

Another form generation library

Latest Version: 2.0a2

Deform

A Python HTML form library. It runs under Python 2.6, 2.7, and 3.2.

Please see http://docs.pylonsproject.org/projects/deform/en/latest/ for the documentation.

See https://github.com/Pylons/deform for in-development version.

Changes

0.9.5 (2012-04-27)

  • Add translations for TinyMCE. Thanks OCHIAI, Gouji.
  • Japanese translation thanks to OCHIAI, Gouji.
  • Modified Russian translation thanks to aleksandr.rakov
  • Date(Time)Widget supports now options to configure it, thx to gaston tjebbes, kiorky
  • FileUploadWidget now sanitizes IE/Windows whole-path filenames before passing them back to the caller during deserialization/validation.
  • Add docs and dev setup.py aliases ala Pyramid.
  • Add MoneyInputWidget widget type.
  • Allow a custom i18n domain to be used for the "Add ${subitem_title}" link of a SequenceWidget. See https://github.com/Pylons/deform/issues/85 .
  • Allow the use of Integer values with SelectWidget. See https://github.com/Pylons/deform/issues/81 .
  • CheckedInputWidget and CheckedPasswordWidget now populate the "confirm" element with the cstruct value (for edit forms).
  • Update to JQuery 1.7.2.
  • Update to jquery.form 3.09.

0.9.4 (2012-02-14)

  • No longer Python 2.5 compatible. Python 2.6+ is required.
  • Python 3.2 compatible.
  • Translate title attribute for remove button in sequence fields.
  • Do not output empty error messages for sequence items. After translation these would insert the PO file metadata.
  • Update to lingua for translations, add french translation
  • fix multiple i18n issues.
  • Fix a bug where displaying error could lead on an error when you have imbricated Mapping objects
  • Fix issue #54: form.pt does not show validation errors from the top node of the schema. See https://github.com/Pylons/deform/issues/54 for more information.
  • Previously, all CheckedInputWidget and CheckedPasswordWidget fields had hardcoded input[name] attributes of 'value' and 'confirm'. When deserializing a form, this caused colander.null to be passed to the widget deserialization function since neither submitted value matched the name of the field. This change simply replaces 'value' with the name of the field and 'confirm' with the name of the field with '-confirm' appended.
  • In select widget, add css_class to <select> rather than only <option>.
  • Allow RichText fields to load their editor only after clicking on them
  • There is no longer a deform_ajaxify global javascript function. Instead forms are AJAXified directly by the javascript callback for the form.

0.9.3 (2011-08-10)

  • Update Dutch translations.
  • Translate title and description of items for sequence fields.
  • Add a new API method to field objects: translate. This method will use the translator passed to the underlying renderer to translate message ids into text.

0.9.2 (2011-07-22)

  • Chameleon 2 compatibility.
  • Use default widgets for a schema's baseclass if known instead of always falling back to a text widget.
  • Deform now includes a beautify.css (contributed by Ergo^) in its static directory, which can be used to make form element styling prettier.
  • Moved deformdemo into its own package and Github repository (https://github.com/Pylons/deformdemo).

0.9.1 (2011-06-23)

  • Add Dutch translation.

  • Add the deform.widget.DateTimeWidget widget, which uses the jQueryUI Timepicker add-on.

    DateTimeWidget uses the ISO8601 combined date and time format internally, as expected by colander.DateTime, but converts to the more friendly separate date and time format for display in the widget.

    This widget is now the default for colander.DateTime schema types.

  • Upgrade to jquery-ui 1.8.11, as required by the timepicker.

  • Compile all .po files to .mo in deform/locale and remove Texan locale (funny, but breaks python setup.py compile_catalog with an UnknownLocale error.)

  • Fix references to repoze.bfg and update obsoletes URLs in the demo application

  • Remove unused jquery.autocomplete.min.js file from static directory.

  • SelectWidget now has a size attribute to support single select widgets that are not dropdowns.

  • The value fed to the deform.form.Button class as name would generate an invalid HTML id if it contained spaces. Now it converts spaces to underscores if they exist in the name. See https://github.com/Pylons/deform/pull/14 .

  • Deformdemo application now has a Time field demonstration.

  • Deform Chameleon templates now contain i18n:translate tags.

  • German translation updated.

  • Fixed invalid HTML generated for "select" widget.

  • When using an ajax form without a redirect, a submit overwrites the form. In the case of a form validation failure on first submit, no event handlers were registered to submit the form via ajax on the second submit. This is now fixed. See https://github.com/Pylons/deform/pull/1 .

0.9 (2011-03-01)

  • Moved to GitHub (https://github.com/Pylons/deform).
  • Added tox.ini for testing purposes.
  • Fix select dropdown behavior on Firefox by fixing CSS (closes http://bugs.repoze.org/issue152).
  • Removed wufoo.css, minimized form.css. Changed templates around to deal with CSS changes.
  • Sequence widgets now accept a min_len and a max_len argument, which influences its display of close and add buttons.
  • Convert demo application from repoze.bfg to Pyramid.
  • Depend on Chameleon<1.999 (deform doesn't yet work with Chameleon 2).

0.8.1 (2010-12-17)

Features

  • Allow deform.form.Button class to be passed a disabled flag (false by default). If a Button is disabled, its HTML disabled setting will be set true.

0.8 (2010-12-02)

Features

  • Added Polish locale data: thanks to Marcin Lulek.

Bug Fixes

  • Fix dynamic sequence item adding on Chrome and Firefox 4. Previously if there was a validation error rendering a set of sequence items, the "add more" link would be rendered outside the form, which would cause it to not work. Wrapping the sequence item <li> element in a <ul> fixed this.

0.7 (2010-10-10)

Features

  • Added Danish locale.
  • Added Spanish locale: thanks to David Cerna for the translations!
  • DatePartsWidget now renders error "Required" if all blank or "Incomplete" if partially blank for consistency with the other widgets.
  • Different styling involving <li> and <ul> for checkbox choice, checked input, radio choice, checked password, and dateparts widgets (via Ergo^). See http://bugs.repoze.org/issue165.

Dependencies

  • Deform now depends on colander version 0.8 or better (the demo wants to use schema bindings).
  • Deform now depends on Chameleon (uppercase) rather than chameleon to allow for non-PyPI servers.

Demo

  • New addition to the demonstration application: schema binding.

0.6 (2010-09-03)

Features

  • Sequence widgets are no longer structural by default; they now print the label of the sequence above the sequence adder.

  • Radio buttons in a radio button choice widget are now spaced closer together and the button is on the left hand side.

  • The sequence remove button is no longer an image.

  • The sequence widget now puts the sequence adding link after any existing items in the sequence (previously the link was always beneath the sequence title).

  • It is now possible to associate a widget with a schema node within the schema directly. For example:

    import colander
    import deform.widget
    
    class MySchema(Schema):
        description = colander.SchemaNode(
                          colander.String(),
                          widget=deform.widget.RichTextWidget()
                          )
    

    For more information, see "Changing the Default Widget Associated With a Field" in the documentation.

  • The constructor of deform.Field objects (and thus deform.Form objects) now accept arbitrary keyword arguments, each of which is attached to the field or form object being constructed, as well as being attached to its descendant fields recursively.

  • The form object's template now respects the css_class argument / attribute of the form node.

  • CheckboxChoice and RadioChoice widgets now use <ul> and <li> to display individual choice elements (thanks to Ergo^), and both widgets put the label after the element instead of before as previously.

  • The deform.widget.AutocompleteInputWidget widget now uses JQuery UI's autocomplete sublibrary <http://docs.jquery.com/UI/Autocomplete> instead of the jquery.autocomplete library to perform its job in order to reduce the number of libraries needed by Deform. Some options have been changed as a result, and the set of resources returned by form.get_widget_resources has changed.

    This change also implies that when a widget which uses a remote URL as a values input, the remote URL must return a JSON structure instead of a \n-delimited list of values.

Requirements

  • This Deform version requires colander version 0.7.3 or better.

Bug Fixes

  • RichTextWidget, AutocompleteInputWidget, TextInputWidget with input masks, and CheckedInputWidget with input masks could not be used properly within sequences. Now they can be. See also Internal and Backwards Incompatibilities within this release's notes. This necessitated new required deform.load() and deform.addCallback() JavaScript APIs.
  • Radio choice widgets included within a submapping no longer put their selections on separate lines.
  • Rich text widgets are now 500 pixels wide by default instead of 640.
  • RadioChoiceWidgets did not work when they were used within sequences. Making them work required some changes to the its template and it added a dependency on peppercorn >= 0.3.
  • To make radio choice widgets work within sequences, the deform.addSequenceItem JavaScript method needed to be changed. It will now change the value of name attributes which contain a marker that looks like an field oid (e.g. deformField1), and, like the code which changes ids in the same manner, appends a random component (e.g. deformField1-HL6sgP). This is to support radio button groupings.
  • The mapping and sequence item templates now correctly display errors with msg values that are lists. Previously, a repr of a Python list was displayed when a widget had an error with a msg value that was a list; now multiple <p> nodes are inserted into the rendering, each <p> node containing an individual error message. (Note that this change requires colander 0.7.3).

Backwards Incompatibilities

  • The JavaScript function deform.load() now must be called by the HTML page (usually in a script tag near the end of the page, ala <script..>deform.load()</script>) which renders a Deform form in order for widgets which use JavaScript to do proper event and behavior binding. If this function is not called, built-in widgets which use JavaScript will no longer function properly.
  • The JavaScript function deformFocusFirstInput was removed. This is now implied by deform.load().
  • The closebutton_url argument to the SequenceWidget no longer does anything. Style the widget template via CSS to add an image.

Internal

  • Provided better instructions for running the demo app and running the tests for the demo app in deformdemo/README.txt.
  • Try to prevent false test failures by injecting sleep statements in things that use browser.key_press.
  • Moved deformdemo/tests/test_demo.py to deformdemo/test.py as well as moving deformdemo/tests/selenium.py to deformdemo/selenium.py. Removed the deformdemo/tests subdirectory.
  • The date input widget now uses JQueryUI's datepicker functionality rather than relying on JQuery Tools' date input. The latter was broken for sequences, and the former works fine.
  • The various deform* JavaScript functions in deform.js have now been moved into a top-level namespace. For example, where it was necessary to call deformFocusFirstInput() before, it is now necessary to call deform.focusFirstInput().
  • Make the TinyMCE rich text widget use mode: 'exact' instead of mode: 'textareas'.
  • richtext, autocomplete_input, textinput, checked_input, and dateinput, and form templates now use the new deform.addCallback indirection instead of each registering their own JQuery callback or performing their own initialization logic, so that each may be used properly within sequences.
  • Change sequence adding logic to be slightly simpler.
  • The sample app form page now calls deform.load() rather than deformFocusFirstInput().
  • Added new demo app views for showing a sequence of autocompletes, a sequence of dateinputs, a sequence of richtext fields, a sequence of radio choice widgets and a sequence of text inputs with masks and tests for same.

Documentation

  • Added a note about get_widget_resources to the "Basics" chapter.
  • Added a note about deform.load() JavaScript requiredness to the "Basics" chapter.
  • Add new top-level sections named Widget Templates and Widget JavaScript to the "Widgets" chapter.

0.5 (2010-08-25)

Features

  • Added features which make it possible to inquire about which resources (JavaScript and CSS resources) are required by all the widgets that make up a form rendering. Also make it possible for a newly created widget to specify its requirements. See "Widget Requirements and Resources" in the widgets chapter of the documentation.
  • Add the get_widget_requirements method to deform.Field objects.
  • Add the get_widget_resources method to deform.Field objects.
  • Allow deform.Field (and deform.Form) objects to accept a "resource registry" as a constructor argument.
  • Add the deform.Field.set_widgets method, which allows a (potentially nested) set of widgets to be applied to children fields of the field upon which it is called.
  • Add the deform.widget.TextInputCSV widget. This widget is exactly like the deform.widget.TextAreaCSV widget except it accepts a single line of input only.
  • The default widget for colander.Tuple schema types is now deform.widget.TextInputCSV.
  • The deform.widget.FileUploadWidget now returns an instance of deform.widget.filedict instead of a plain dictionary to make it possible (using isinstance) to tell the difference between file upload data and a plain data dictionary for highly generalized persistence code.

0.4 (2010-08-22)

Bug Fixes

  • When the hidden widget is used to deserialize a field, return colander.null rather than the empty string so that it may be used to represent non-text fields such as colander.Integer. This is isomorphic to the change done previously to deform.TextInputWidget to support nontextual empty fields.
  • Fix typo about overriding templates using set_zpt_renderer in templating chapter.
  • Fix link to imperative schema within in Colander docs within "Basics".
  • Remove duplicate deform.widget.DateInputWidget class definition.

Features

  • Add a deform.widget.RichTextWidget widget, which adds the TinyMCE WYSIWIG javascript editor to a text area.
  • Add a deform.widget.AutocompleteInputWidget widget, which adds a text input that can be supplied a URL or iterable of choices to ease the search and selection of a finite set of choices.
  • The deform.widget.Widget class now accepts an extra keyword argument in its constructor: css_class.
  • All widgets now inherit a css_class attribute from the base deform.widget.Widget class. If css_class` contains a value, the "primary" element in the rendered widget will get a CSS class attribute equal to the value ("primary" is defined by the widget template's implementor).
  • The deform.Field class now as an __iter__ method which iterates over the children fields of the field upon which it is called (for item in field == for item in field.children).

0.3 (2010-06-09)

Bug Fixes

  • Change default form action to the empty string (rather than .). Thanks to Kiran.

Features

  • Add deform.widget.DateInputWidget widget, which is a date picker widget. This has now become the default widget for the colander.Date schema type, preferred to the date parts widget.
  • Add text input mask capability to deform.widget.TextInputWidget.
  • Add text input mask capability to deform.widget.CheckedInputWidget.

Backwards Incompatibilities

  • Custom widgets must now check for colander.null rather than None as the null sentinel value.
  • Dependency on a new (0.7) version of Colander, which has been changed to make using proper defaults possible; if you've used the default argument to a colander.SchemaNode, or if you've defined a custom Colander type, you'll want to read the updated Colander documentation (particularly the changelist). Short story: use the missing argument instead.
  • If you've created a custom widget, you will need to tweak it slightly to handle the value colander.null as input to both serialize and deserialize. See the Deform docs at http://docs.repoze.org/deform for more information.

0.2 (2010-05-13)

  • Every form has a formid now, defaulting to deform. The formid is used to compute the id of the form tag as well as the button ids in the form. Previously, if a formid was not passed to the Form constructor, no id would be given to the rendered form and the form's buttons would not be prefixed with any formid.

  • The deform.Form class now accepts two extra keyword arguments in its constructor: use_ajax and ajax_options.

    If use_ajax is True, the page is not reloaded when a submit button is pressed. Instead, the form is posted, and the result replaces the DOM node on the page.

    ajax_options is a string which allows you to pass extra options to the underlying AJAX form machinery when use_ajax is True.

  • Added a couple Ajax examples to the demo app.

  • Add a rudimentary Ajax chapter to the docs.

0.1 (2010-05-09)

  • Initial release.
