README

Adds Deepl translation API to a Fluent translated SilverStripe CMS. For now it only adds UI-Elements to texty fields (TextField, TextareaField, HTMLEditorField) to translate their contents.

Installation

composer require arillo/silverstripe-deepl-translator

Configuration

Create a Deepl API key and add it to your .env:

DEEPL_APIKEY="<YOUR_DEEPL_APIKEY>"

If you are using the glossary feature, it is necessary, to set a unique name prefix in your .env. It will prevent old glossaries from deletion if their names do not start with that name prefix. This is handy if you are using the same API key in multiple instances (e.g. dev & prod).

DEEPL_GLOSSARY_NAME_PREFIX="myky-dev"

Configure your DataObjects to display the Deepl translation handles.

NOTE: It is important, that this configurations happens AFTER fluent was added to these DataObjects. Otherwise the UI will not appear.

Let's assume you have the following fluent config, named myfluentcms:

---
Name: myfluentcms
After: 
 - '#basei18n'
 - '#fluentcms'
 - '#fluentcms-pages'
---
SilverStripe\i18n\i18n:
  default_locale: de_CH

Arillo\Elements\ElementBase:
  extensions:
    - 'TractorCow\Fluent\Extension\FluentVersionedExtension'

Field-wise translator

Apply the deepl config after #myfluentcms:

---
Name: mydeepl
After: 
 - '#myfluentcms'
 - '#silverstripe-deepl-translator'
---
SilverStripe\CMS\Model\SiteTree:
  extensions:
    - Arillo\Deepl\FieldWiseTranslationExtension

Arillo\Elements\ElementBase:
  extensions:
    - Arillo\Deepl\FieldWiseTranslationExtension

Make URLSegmentFields translatable (CAUTION: is expirimental; JS implementation WIP):

Arillo\Deepl\FieldWiseTranslationExtension:
  deepl_fieldwise_translate_urlsegment_field: true

Alternate field value gathering for field-wise translator

To preload current values for field-wise translations this module uses the following method $record->{$fieldName}. However, it is possible to specify an alternate data source by implementing a class method called deeplFieldValueFromRecord to overwrite the default behavior, e.g.:

    // in some DataObject class
    // ...

    public function deeplFieldValueFromRecord($fieldName)
    {
        switch ($fieldName) {
            case 'AOLink_Title':
                return $this->LinkObject()->Title;

            case 'AOLink_URL':
                return $this->LinkObject()->URL;

            default:
                return $this->{$fieldName};
        }
    }

Add translation features to selected fields only:

Below you see an example configuration that will only add field-wiese translation features to Title and Description for that App\Model\MyDataObject.

App\Model\MyDataObject:
  extensions:
    - Arillo\Deepl\FieldWiseTranslationExtension
  deepl_fieldwise_included_fields:
    - Title
    - Description

DataObject-wise translator

Automatically translates all translatable fields of a DataObject. Just add Arillo\Deepl\DataObjectWiseTranslationExtension to extensions of that DataObject class, e.g.:

---
Name: mydeepl
After: 
 - '#myfluentcms'
 - '#silverstripe-deepl-translator'
---
SilverStripe\CMS\Model\SiteTree:
  extensions:
    - Arillo\Deepl\DataObjectWiseTranslationExtension

Arillo\Elements\ElementBase:
  extensions:
    - Arillo\Deepl\DataObjectWiseTranslationExtension

Optionally you can define relations that also will be translated. Make sure that the according DataObject also use soem Fluent extensions.

To configure the wanted relations just use the deepl_dataobject_included_relations configuration, e.g.:

Arillo\Elements\ElementBase:
  extensions:
    - Arillo\Deepl\DataObjectWiseTranslationExtension
  deepl_dataobject_included_relations:
    - Elements
    - LinkObject

Glossary

If you want to use the glossary features of Deepl, you can edit your glossaries in SiteConfig.

You need to set a glossary name prefix in your .env, like so:

DEEPL_GLOSSARY_NAME_PREFIX="mysite-prod"

These prefixes are usefull if you run your app in different environments, e.g.: dev or live.

As of this writing, keep in mind that the deepl glossary API does not allow for updates of glossaries. So updates are deletes and creates. The purging mechanism takes the name prefixes into account. E.g.: If your env is set to mysite-prod it will only delete glossaries where the name starts with that prefix. This should help to prevent unwanted glossary deletes.

CMS

In CMS you have to add USE_DEEPL permission to non-admin groups.
