Plone Integration with YAFOWIL

This is the Plone Integration for YAFOWIL

Functionality

Resources Integration with GenericSetup

Addon widgets may provide custom javascripts, CSS, images and so on.

This package registers the directories containing these assets as resource directories. Thus they can be accessed from the webbrowser. The registration schema is ++resource++MODULENAME/....

The "YAFOWIL Form Library" GS profile registers all resources related to so called "resource groups" in the CSS and javascript registries.

This resource groups must be enabled explicitly(!). The resource groups configuration happens via the portal registry.

You need to provide a Generic setup profile containing a registry.xml with the resource groups configuration, e.g.:

<!-- yafowil.widget.array -->
<record name="yafowil.widget.array.common">
  <field type="plone.registry.field.Bool">
    <title>Array widget common resources</title>
  </field>
  <value>True</value>
</record>

The record name maps to the resource group name.

Note

The profile to register the resoures in resource registries (the default profile) must run AFTER the resource groups have been configured. Thus you are forced to use 2 profiles; one registering the resource groups, and one depending on the resource groups profile and the yafowil profile in it's metadata.xml. In other words, if you add a plugin (like yafowil.widget.autocomplete) after yafowil.plone installation you MUST re-install yafowil.plone in order to get new plugin's resources registered.

Take a look into registry.xml of the yafowil.plone:profiles/demoresources profile for more examples or consider the referring resource providing code inside the addon widgets, usually contained in the packages __init__.py file to get available resource groups.

Integration with Translation

The package adds an translation method for Zope2 i18n messages. It's added using by defining a global preprocessor

Request wrapper

This package registers a global preprocessor for YAFOWIL. It wraps the Zope2 request by an own request instance providing the behavior expected by YAFOWIL. Spezial behaviors:

File Uploads provided by Zope2 as ZPublisher.HTTPRequest.Fileupload objects are turned into Dicts with the keys:

file
file-like object to read data from
filename
submitted name of the upload
mimetype
type of the upload
headers
all headers
original
keeps the original ZPublisher.HTTPRequest.Fileupload object

Base Forms

This package ships with base forms to be extended.

The following form base classes are available:

yafowil.plone.form.BaseForm
does not define a `__call__` method: define a template in ZCML or a `__call__` method. It provides a method named `render_form` which processes and renders the form.
yafowil.plone.form.Form
renders the naked form on __call__.
yafowil.plone.form.YAMLBaseForm
similar to BaseForm above. Expects properties form_template pointing to a YAML file and message_factory providing the message factory used for YAML message strings.
yafowil.plone.form.YAMLForm
similar to YAMLBaseForm renders the naked YAML form on __call__.

Concrete implementation may look like:

>>> from yafowil.base import factory
>>> from yafowil.plone.form import Form

>>> class MyForm(Form):
...     action_resource = '@@view_name_callable_by_browser'
...
...     def prepare(self):
...         form = factory(
...             'form',
...             name='myform',
...             props={
...                 'action': self.form_action,
...             })
...
...         # form widgets creation here...
...
...         self.form = form

Convenience for creating YAML forms:

>>> from zope.i18nmessageid import MessageFactory
>>> from yafowil.plone.form import YAMLBaseForm

>>> class MyYAMLForm(YAMLBaseForm):
...     action_resource = '@@view_name_callable_by_browser'
...     form_template = 'package.name:forms/myform.yaml'
...     message_factory = MessageFactory('package.name')

Form classes inherit from Products.Five.BrowserPage, thus they must be registered via ZCML browser:page directive:

<browser:page
  for="*"
  name="form_registration_name"
  class=".forms.MyYAMLForm"
  template="myyamlform.pt"
  permission="cmf.ModifyPortalContent"
/>

Forms build with this base form classes need a template in order to insert such a form in a layout. It must be called inside a wrapper template `myform.yaml`:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"
      xmlns:tal="http://xml.zope.org/namespaces/tal"
      xmlns:metal="http://xml.zope.org/namespaces/metal"
      xmlns:i18n="http://xml.zope.org/namespaces/i18n"
      lang="en"
      metal:use-macro="context/main_template/macros/master"
      i18n:domain="package.name">
  <body>
    <metal:content-core fill-slot="content-core">
      <metal:block define-macro="content-core">
        <tal:form replace="structure view/render_form" />
      </metal:block>
    </metal:content-core>
  </body>
</html>

History

2.0.2

  • fix resource group names [thet]
  • correct getSite import, cleanup [thet]

2.0.1

  • Provdide default title attribute value for richtext blueprint of yafowil.widget.richtext addon widget in order to provide TinyMCE configuration as expected by plone integration.

2.0

  • YAFOWIL resource including configuration via generic setup. [rnix, 2012-10-03]

1.3.1

  • Simplify base forms for plone. [jensens, 2012-05-21]
  • Not ZIP safe! [jensens, 2012-04-15]

1.3

  • GS profile marker - fix wrong filename. [rnix, 2012-04-11]
  • Add yafowil.plone.form module containing base classes. [rnix, 2012-04-11]

1.2

  • Rename to yafowil.plone - seems a 2 at the end of a package name confuses easy_install. wtf!? [jensens, 2012-03-20]

1.1

  • Depend on yafowil 1.3 in setup.py and bump version. [jensens, 2012-03-20]

1.0

  • Resources are registered using the new plugin infrastructure. Theres now an import step for generic setup registering all javascripts and stylesheets provided by the plugins. They are registred without any thirdparty dependencies. If a resource is already registered its registration is skipped. Such its possible to register or overide the defaults using xml files. [jensens, 2012-02-01]
  • Automatic browserresources for plugins. [jensens, 2012-02-16]
  • Depends on yafowil 1.3 plugin infrastucture. [jensens, 2012-02-15]
  • Example form and senseful default-classes and plans for plone. [hpeter, bennyboy, 2012-02-15]

1.0-beta

  • Made it work. [jensens, rnix, et al, 2010-12-27]
