plone.volto 3.0.0a1

Volto Blocks Support

plone.volto enables the new Volto Blocks editor on Document, Language Root Folder and Site Root.

Multilingual Support

plone.volto supports multilingual websites. Install PAM before installing this package and demo homepages will be created in each enabled language. Currently only support for EN/DE.

Volto Blocks for Plone Site Root

plone.volto contains a hack to make the Plone site Volto blocks-enabled with some demo content. You can take only the hack to enable the blocks on your site.

You can see it in action in the Volto demo: https://volto.kitconcept.com

Install the provided profile to install it by default:

plone.volto:default-homepage

e.g. in your GS metadata.xml along with your other dependencies:

<metadata>
<version>1000</version>
<dependencies>
  <dependency>plone.volto:default-homepage</dependency>
</dependencies>
</metadata>

Document Content Type

plone.volto disables the Richtext and Table of Contents behaviors for the Document content type. Rich Text functionality is provided by the new Volto Blocks editor. The Table of Contents functionality is provided by the Table of Contents Block in Volto.

CORS Profile

A quick helper for enable CORS for development config is also provided in the plone.volto module. So you can call:

<include package="plone.volto.cors" />

from your ZCML while developing.

Enable it on demand, since it’s considered a security issue if you enable CORS in your productions sites.

It’s planned that Volto will feature a development pass-through proxy to the backend in the future. It will be addressed in next sprints.

ZLog Patch

p.restapi low level errors are routed through the ancient ZLog and are plone_error enabled, making it difficult to follow since all are marked with a UUID. Specially if using helpers like Sentry. This patch removes the UUID so the same error is categorized all together. This is planned to be addressed in next sprints.

Patch for subject Field

There are some problems of serialization on special characters derivated from how the current shape of the Plone’s default Dexterity subjects field that has to be addressed in order to make it work properly with Volto (and other systems that are not Plone). This will be fixed in core in upcoming sprints.

Preview Image Behavior

The preview image behavior makes content types provide a preview_image field that can store a preview image that Volto views can pick up. This is especially userful for listings (e.g. listing block customizations) and teaser elements (e.g. teaser blocks such as [volto-blocks-grid](https://github.com/kitconcept/volto-blocks-grid)).

The “volto.preview_image behavior can be enabled in the generic setup XML definition of a content type (e.g. “/profiles/default/types/MyContentType.xml”):

<?xml version="1.0" encoding="UTF-8" ?>
<object i18n:domain="fzj.internet" meta_type="Dexterity FTI" name="MyContentType"
  xmlns:i18n="http://xml.zope.org/namespaces/i18n">

  ...

  <!-- Enabled behaviors -->
  <property name="behaviors" purge="false">
    ...
    <element value="volto.preview_image" />
  </property>
  ...
</object>

Navigation Title Behavior

The navigation title makes content types provide a nav_title field that is used by Volto in the main navigation, the breadcrumbs and the navigation portlet.

The “volto.navtitle behavior can be enabled in the generic setup XML definition of a content type (e.g. “/profiles/default/types/MyContentType.xml”):

<?xml version="1.0" encoding="UTF-8" ?>
<object i18n:domain="fzj.internet" meta_type="Dexterity FTI" name="MyContentType"
  xmlns:i18n="http://xml.zope.org/namespaces/i18n">

  ...

  <!-- Enabled behaviors -->
  <property name="behaviors" purge="false">
    ...
    <element value="volto.navtitle" />
  </property>
  ...
</object>

Head Title Behavior

The headtitle makes content types provide a headtitle field that can be used by Volto in teasers and alikes.

The “volto.head_title” behavior can be enabled in the generic setup XML definition of a content type (e.g. “/profiles/default/types/MyContentType.xml”):

<?xml version="1.0" encoding="UTF-8" ?>
<object i18n:domain="fzj.internet" meta_type="Dexterity FTI" name="MyContentType"
  xmlns:i18n="http://xml.zope.org/namespaces/i18n">

  ...

  <!-- Enabled behaviors -->
  <property name="behaviors" purge="false">
    ...
    <element value="volto.head_title" />
  </property>
  ...
</object>

Image Scales

This package introduces new Plone image scales in Plone and redefines a couple of existing ones. These are know to work well with Volto layout and grid system:

icon 32:32
tile 64:64
thumb 128:128
mini 200:65536
preview 400:65536
teaser 600:65536
large 800:65536
larger 1000:65536
great 1200:65536
huge 1600:65536

This change is opinionated and may collide with your previously defined ones, so make sure your add-on’s profiles are applied AFTER this one.
