Multilingual Sites with Kotti.

Kotti's data model includes a language attribute on the Content class, from which all content types inherit. However, this attribute is neither exposed by Kotti's UI, nor used in any other way. kotti_multilingual provides a generic approach to build multilingual sites.

Work in Progress

kotti_multilingual is still in an early stage of development. It is neither feature complete nor can be considered API stable. Things will change!


The package contains a single content type LanguageRoot which is supposed to be the container of all content in a specific language. All content that is created in (or moved into) such a subtree will be automatically tagged with the language of the root. This is done by subscribing to Kotti's ObjectInsert and ObjectUpdate events.

You can place LanguageRoot instances wherever you want in your content tree, but it is considered best practice to have a tree structure like this:

- /            Document        language neutral
   - /en       LanguageRoot    English
   - /de       LanguageRoot    German
   - /nl       LanguageRoot    Dutch
   - /images   Document        language neutral


To activate the kotti_multilingual add-on in your Kotti site, you need to add an entry to the kotti.configurators setting in your Paste Deploy config. If you don't have a kotti.configurators option, add one. The added entry should look like this:

kotti.configurators = kotti_multilingual.kotti_configure

You can register an optional kotti_multilingual.blacklist with the list of the type names not handled by kotti_multilingual.


The test setup requires additional steps:

$ virtualenv --no-site-packages .
$ source bin/activate
$ pip install -r requirements.txt
$ python setup.py develop
$ python setup.py dev

How to launch tests:
