Localization
============
Flask-Admin makes it possible for you to serve your application in more than one language. To do this, it makes use of
the `Flask-BabelEx `_ package for handling translations. This package is a
fork of the popular `Flask-Babel `_ package, with the following features:
1. It is API-compatible with Flask-Babel
2. It allows distribution of translations with Flask extensions
3. It aims to be more configurable than Flask-Babel
Currently *Flask-BabelEx* is the only supported way of enabling localization support in Flask-Admin.
How to enable localization
--------------------------
1. Install Flask-BabelEx::
pip install flask-babelex
2. Initialize Flask-BabelEx by creating instance of `Babel` class::
from flask import app
from flask.ext.babelex import Babel
app = Flask(__name__)
babel = Babel(app)
3. Create a locale selector function::
@babel.localeselector
def get_locale():
# Put your logic here. Application can store locale in
# user profile, cookie, session, etc.
return 'en'
4. Initialize Flask-Admin as usual.
You can check the `babel` example to see localization in action. When running this example, you can change the
locale simply by adding a query parameter, like *?en=* to the URL. For example, a French version of
the application should be accessible at:
`http://localhost:5000/admin/userview/?lang=fr `_.
