Installation

Install the package from PyPI:
python -m pip install wagtail-localize-smartling

Add "wagtail_localize_smartling" to INSTALLED_APPS in your Django
settings. Make sure it's before "wagtail_localize" and
"wagtail_localize.locales":
INSTALLED_APPS = [
...
"wagtail_localize_smartling",
"wagtail_localize",
"wagtail_localize.locales",
...
]

Configure the plugin in your Django settings:
WAGTAIL_LOCALIZE_SMARTLING = {
# Required settings (get these from "Account settings" > "API" in the Smartling dashboard)
"PROJECT_ID": "<project_id>",
"USER_IDENTIFIER": "<user_identifier>",
"USER_SECRET": "<user_secret>",
# Optional settings and their default values
"REQUIRED": False, # Set this to True to always send translations to Smartling
"ENVIRONMENT": "production", # Set this to "staging" to use Smartling's staging API
"API_TIMEOUT_SECONDS": 5.0, # Timeout in seconds for requests to the Smartling API
}

If your project's locales do not match those in Smartling (e.g. ro in your
project, ro-RO in Smartling), then you can provide a Wagtail locale ID to
Smartling locale ID mapping via the LOCALE_TO_SMARTLING_LOCALE setting:
WAGTAIL_LOCALIZE_SMARTLING = {
"LOCALE_TO_SMARTLING_LOCALE": {
"ro": "ro-RO"
}
}

... or you can specify a callable or a dotted path to a callable in the
LOCALE_MAPPING_CALLBACK setting:
def map_project_locale_to_smartling(locale: str) -> str:
if locale == "ro":
return "ro-RO"
return locale

WAGTAIL_LOCALIZE_SMARTLING = {
# ...
"LOCALE_MAPPING_CALLBACK": "settings.map_project_locale_to_smartling"
}

The callback receives a WAGTAIL_CONTENT_LANGUAGES local code string and is
expected to return a valid mapped locale ID (or the original locale ID).
Note that by default, when syncing translations the project will attempt to
reformat a mixed-case, Smartling-style language code (e.g. zh-CN) into a
Django-style all-lowercase code (e.g. zh-cn). Depending on how language
codes are set up in your project, this behaviour may not be appropriate. You
can disable it by settings the REFORMAT_LANGUAGE_CODES setting to False
(the default is True):
WAGTAIL_LOCALIZE_SMARTLING = {
# ...
"REFORMAT_LANGUAGE_CODES": False
}

Run migrations:
./manage.py migrate

Setup
Smartling project setup
For the plugin to work with a Smartling project, the Django/Wagtail internationalization- and localization-related settings must be compatible with the project's language settings:

Only Wagtail content authored in the same language as the Smartling project's source language can be translated.
Ideally, the language tags in WAGTAIL_CONTENT_LANGUAGES should be the exact, case-insensitive matches for the Smartling projects target locales. For example, if your Smartling project targets fr-FR, then you must have "fr-fr" in your WAGTAIL_CONTENT_LANGUAGES, not just "fr".
However, if that is not possible, use the LOCALE_TO_SMARTLING_LOCALE or LOCALE_MAPPING_CALLBACK settings to map your Wagtail language codes to the Smartling language codes.

Synchronization
The plugin provides a sync_smartling management command that:

Creates jobs in Smartling for new content that's awaiting translation
Checks the status of pending translation jobs
Downloads and applies translations for completed jobs

This command should be set to run periodically via cron or similiar:
./manage.py sync_smartling

We recommend running this regularly, around once every 10 minutes.
Callbacks
As well as the sync_smartling management command, the plugin sets the callbackUrl field on the Smartling jobs it creates to the URL of webhook handler view. This handler will proactively download and apply translations from completed jobs without waiting for the next sync_smartling run. This URL is based on the WAGTAILADMIN_BASE_URL setting, so it's important that's set and accessible from the internet.

[!WARNING]
Callbacks should not be relied on as the only method for downloading translations. Always make sure the sync_smartling command is run regularly to ensure your translations are up-to-date.

Usage
Submitting new content for translation

Updating translations

Signals
This app provides a single wagtail_localize.signals.translation_imported
signal that is sent when translation are imported from Smartling.
Signal kwargs:

sender: The wagtail_localize_smartling.models.Job class
instance: The Job instance for which translation are being imported
translation: The wagtail_localize.models.Translation instance the translations are being imported to.
Use translation.get_target_instance() to get the model instance that the translation is for (e.g. a page or snippet)

Cutting a new release

Bump the version in https://github.com/mozilla/wagtail-localize-smartling/blob/main/src/wagtail_localize_smartling/__init__.py
Update CHANGELOG.md
Commit and land the changes in main (via a PR, or committing to main if you're sure this won't cause clashes)
Tag the release as vX.Y.Z on main – or make a tag via the GH UI in Step 6. (Remember to push up the new tag if you made it locally, with git push --tags)
Add a new Release via https://github.com/mozilla/wagtail-localize-smartling/releases
Select (or create) the new tag, add the title and description
Ensure the new Release is marked as latest (see checkboxes below the Release description)
Publish the new Release within GitHub - automation will take of the rest and push it up to PyPI
