[Flask] Babel tries...

Sun Dec 13 14:26:57 EST 2015

Hi,

I have a simply app:

# Imports
from flask import Flask, jsonify, request, make_response, render_template,
url_for, flash, redirect
from yaml import load, dump
try:
    from yaml import CLoader as Loader, CDumper as Dumper
except ImportError:
    from yaml import Loader, Dumper
from flask.ext.babel import Babel

# Global variables
version = "0.1"
app = Flask(__name__)
app.secret_key = 'el meu secret'

# Babel settings
app.config.from_pyfile('configuration.cfg')
babel = Babel(app)
LANGUAGES = {
    'en': 'English',
    'es': 'Español',
    'ca': 'Català'
}

@babel.localeselector
def get_locale():
    return request.accept_languages.best_match(LANGUAGES.keys())

# Main procedure
def create_new_activity():
    """It creates a new activity after a POST request"""
    flash(request.form.get('name'))
    flash(request.form.get('body'))
    flash(request.form.getlist('tags'))
    return redirect(url_for('add_activity'))

def show_new_activity_form():
    """It shows a form for create a new activity"""
    return render_template('add_activity.html')

@app.route("/add/", methods=['GET', 'POST'])
def add_activity():
    """Add a new activity to the collection"""
    if request.method == 'POST':
        return create_new_activity()
    else:
        return show_new_activity_form()

if __name__ == "__main__":
    app.run(debug=True)

My babel.cfg is

[python: **.py]
[jinja2: **/templates/**.html]
extensions=jinja2.ext.autoescape,jinja2.ext.with_

and my configuration.cfg is

BABEL_DEFAULT_LOCALE="en"

When I run
#!/usr/bin/env sh
pybabel extract -F babel.cfg -o messages.pot templates/
pybabel init -i messages.pot -d translations -l ca
pybabel init -i messages.pot -d translations -l en
pybabel init -i messages.pot -d translations -l es
pybabel compile -d translations

I get EMPTY (nothing to be translated) files, although in my templates I
have the base.html with words for translating:

Any hints?
