django makemessages does nothing

When I run django-admin makemessages -l en nothing happens and no po files are created. It only says processing locale en

This is my folder structure

/myproject
    myapp/
    locale/
    media/
    static/
    templates/
    db.sqlite
    manage.py
    settings.py
    urls.py
    wsgi.py

settings.py

import os

BASE_DIR = os.path.dirname(os.path.abspath(__file__))

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'myapp',
]

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django_user_agents.middleware.UserAgentMiddleware',
]

ROOT_URLCONF = 'urls'

WSGI_APPLICATION = 'wsgi.application'

LANGUAGE_CODE = 'fr'

TIME_ZONE = 'UTC'

USE_I18N = True

USE_L10N = True

USE_TZ = True

LOCALE_PATHS = [os.path.join(BASE_DIR, 'locale')]

Solution

I realized that makemessages does not create po files if translations are not referenced in any of the templates

I was expecting makemessages to create an empty po file that can I continue editing, but it does not work that way. At least one of the templates must have translations for the file to be created at the first time.

{% load i18n %}
....
{% trans 'Welcome' %}

python manage.py makemessages -l en

I hope this will be useful to anyone encountering the same issue
