plone.app.multilingual 1.2.2

Root Language folders

After the setup, PAM will create root folders for each of your site’s languages and put translated content into the appropriate folders. A language folder implements INavigationRoot, so from the user’s point of view, each language is “jailed” inside its correspondent language folder. There are event subscribers in place to capture user interaction with content and update the language in contents accordingly, for example when user moves or copy content between language folders.

Babel view

An evolution of the LP translate view, unified for either Archetypes and Dexterity content types. It features an already translated content viewer for the current content being edited via an ajaxified dinamic selector that shows them on the fly on user request.

Language independent fields

PAM has support for language independent fields, but with a twist respect the LP implementation. As PAM does design does not give more relevance to one translated object above the others siblings (has no canonical object), fields marked as language independent get copied over all the members of the translation group always. The PAM UI will warn you about this behavior by reminding you that the values in the field on the other group participants will be overwritten.

Translation locator policy

When translating content, this policy decides how it would be placed in the site’s structure. There are two policies in place:

• LP way, the translation gets placed in the nearest translated folder in parent’s hierarchy

• Ask user where to place the translated element in the destination language root folder

Language selector policy

While browsing the site, the language selector viewlet allows users to switch site’s content language and ease access between translations of the current content. There are two policies in place in case the translation of a specific language does not exist (yet):

• LP way, the selector shows the nearest translated container.

• Shows the user an informative view that shows the current available translations for the current content.

Neutral root folder support

The root language folders are used to place the tree of the correspondent language content. However, there are some use cases we need content that does not belongs to any language. For example, for assets or side resources like images, videos and documents. There is need to maintain a language neutral folder for place this kind of objects. After PAM setup, there is a special folder called Language shared. All items placed in this folder will have neutral as its default language and will be visible from the other root language folders as they were placed there.

Translation map

In order to ease the translation tasks, we devised a tool that displays in a useful way all the current translated objects and its current translation information. The map also shows a list of missing translations in case you want to build a mirrored (completely) translated site.

Google Translation Service integration

If you are subscriber of the Google Translation service (a paid service), you can setup your API key on Languages site setup. Then, you will notice a new icon in the babel view that takes the original field on the left side and using Google Translations service, translates its contents and fill the right side field.

LinguaPlone migration

You can migrate your existing LP powered sites to PAM using the Migration tab in the Languages control panel. The migration has been divided into 4 steps for separation of concerns and for improving the success of each of the required procedures.

Archetypes

By default, if PAM is installed, Archetypes-based content types are marked as translatables

Dexterity

Users should mark a dexterity content type as translatable by assigning a the multilingual behavior to the definition of the content type either via file system, supermodel or through the web.

Archetypes

The language independent fields on Archetype-based content are marked the same way as in LinguaPlone:

atapi.StringField(
    'myField',
    widget=atapi.StringWidget(
    ....
    ),
    languageIndependent=True
),

Dexterity

There are four ways of achieve it.

from plone.multilingualbehavior import directives
directives.languageindependent('field')

<field name="myField" type="zope.schema.TextLine" lingua:independent="true">
    <description />
    <title>myField</title>
</field>

from plone.multilingualbehavior.interfaces import ILanguageIndependentField
alsoProvides(ISchema['myField'], ILanguageIndependentField)

There is no canonical content object

Having a canonical object on the content space produces a dependency which is not orthogonal with the normal behavior of Plone. Content objects should be autonomous and you should be able to remove it. This is the reason because we removed the canonical content object. There is a canonical object on the translation infrastructure but is not on the content space.

Translation reference storage

In order to maintain the relations between the different language objects we designed a common object called a translation group. This translation group has an UUID on its own and each object member of the group stores it in the object catalog register. You can use the ITranslationManager utility to access and manipulate the members of a translation group given one object of the group.

Adapt all the steps on translation

The different aspects involved on a translation are adapted, so it’s possible to create different policies for different types, sites, etc.

• ITranslationFactory - General factory used to create a new content

  • ITranslationLocator - Where we are going to locate the new translated content

    Default : If the parent folder is translated create the content on the translated parent folder, otherwise create on the parent folder.

  • ITranslationCloner - Method to clone the original object to the new one

    Default : Nothing

  • ITranslationIdChooser - Which id is the translation

    Default : The original id + lang code-block

• ILanguageIndependentFieldsManager - Manager for language independent fields

  Default: Nothing

Language get/set via an unified adapter

In order to access and modify the language of a content type regardless the type (Archetypes/Dexterity) there is a interface/adapter:

plone.multilingual.interfaces.ILanguage

You can use:

from plone.multilingual.interfaces import ILanguage
language = ILanguage(context).get_language()

or in case you want to set the language of a content:

language = ILanguage(context).set_language('ca')

Translatable marker interface

In order to know if a content can be translated there is a marker interface:

plone.multilingual.interfaces.ITranslatable
