# How to set up language files
|
|
|
|
Inspired by https://phrase.com/blog/posts/i18n-advantages-babel-python/#Integration_with_Jinja2_templates
|
|
|
|
Add translate statements to jinja2 templates
|
|
|
|
```
|
|
<title>{% trans %}Page title{% endtrans %}</title>
|
|
```
|
|
|
|
To parse the jinja templates to extract the messages, first
|
|
create a file named `babel-mapping.ini`:
|
|
|
|
```
|
|
[python: **.py]
|
|
[jinja2: **/templates/**.html]
|
|
extensions=jinja2.ext.i18n,jinja2.ext.autoescape,jinja2.ext.with_
|
|
```
|
|
|
|
Then extract the base messages from templates:
|
|
> pybabel extract -F babel-mapping.ini -o locale/messages.pot ./
|
|
|
|
This file is not persisted on github.
|
|
|
|
If the above command gives this ouput:
|
|
```
|
|
AttributeError: module 'jinja2.ext' has no attribute 'autoescape'
|
|
```
|
|
|
|
Just comment out the extensions line in the `babel-mapping.ini` file:
|
|
```
|
|
[python: **.py]
|
|
[jinja2: **/templates/**.html]
|
|
;extensions=jinja2.ext.i18n,jinja2.ext.autoescape,jinja2.ext.with_
|
|
```
|
|
|
|
Then rerun the command for extracting base messages.
|
|
|
|
|
|
Now setup a new language (french) using the init command:
|
|
> pybabel init -d locale -l fr -i locale/messages.pot
|
|
|
|
Or update an existing language using:
|
|
> pybabel update -d locale -l fr -i locale/messages.pot
|
|
|
|
Run compile command to generate MO files:
|
|
> pybabel compile -d locale -l fr
|
