cs.linguacopier

Full Documentation

This products adds an action to copy contents to a selected language.

We have faced many times the work to create the contents of a site in one language and then recreate it in another language to let the customer or translators translate it.

This products provides an action with several options, which allows the content editor to recreate the contents of one section of the site in one or more languages, easing the work of the content editor.

Disclaimer: this product does not effectively translate the contents (does not translate "House" to "Casa"), it just copies the actual content in the other language.

Installation

Install cs.linguacopier by adding cs.linguacopier it to your project's dependencies (either buildout, pyproject.toml, requirements.txt, uv or whatever you use to manage your Plone project's dependencies).

REST API

When plone.restapi is installed, the copier is also available over REST, so a Volto front end can use it:

POST /<content>/@copy-content-to

with a JSON body such as:

{
  "target_languages": ["es", "ca"],
  "include_context": true,
  "include_children": true
}

The endpoint requires the Manage portal permission and always answers 200 with a per-object result. See the documentation for the full request and response contract.

Changelog

2.0 (2026-10-02)

Breaking changes

• Replace pkg_resources namespace with PEP 420 native namespace. Support only Plone 6.2 and Python 3.10+. #3928
• Rename the @@copy-content-to form fields to include_context and include_children, matching the new REST API parameter names.

New features

• Add a POST /<content>/@copy-content-to REST service so that a Volto front end can copy content and its subobjects into target languages. The endpoint is available when plone.restapi is installed.
• Show the outcome of a copy in the classic-UI @@copy-content-to form: a per-object report (created, updated, skipped, failed) with the reasons for the failures, exportable as CSV.
• Stop offering the content's own language as a copy target: the @@copy-content-to form lists only the other supported languages (and is hidden when there is none), and the REST endpoint rejects a request that names the content's own language.

Bug fixes

• Fix copy_other_things adapter lookup and updating of existing properties in copy_other_properties.
