Django JavaScript translation empty catalog (i18n/jsi18n)

Question

I keep ending up with an empty catalog in my jsi18n JavaScript. I have tried all the solutions on StackOverflow including Empty catalog when internationalizing JavaScript code, but the catalog is still empty. My setup is this: ``` project_dir - locale - nl (contains LC_MESSAGES with django.po and djangojs.po) - app1 - app2 - main_app - settings.py - urls.py - wsgi.py ``` In settings.py I have ``` # Where to find locale LOCALE_PATHS = ( os.path.join(SITE_ROOT, 'locale'), ) ``` SITE_ROOT is the absolute path to my project dir, so this translates to In urls.py I have ``` # i18n js_info_dict = { 'domain': 'djangojs', 'packages': ('wrnpro', ), } ``` and ``` (r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict), ``` as part of my urls. If I run the app and call `http://localhost:8000/jsi18n/` I get ``` /* gettext library */ var catalog = new Array(); function pluralidx(count) { return (count == 1) ? 0 : 1; } … ``` So far I have tried every variation of settings etc. I could f…

Accepted Answer

This is what ended up working for me:

```
js_info_dict = {
   'domain': 'django',
   'packages': None,
}

urlpatterns = [
    url(r'^jsi18n/$', javascript_catalog, js_info_dict, name='javascript-catalog'),
    # ...
]
```

Still not working? Troubleshooting tips:

I don't know particularly why this works, but I can tell you how I found out how to make it work. If you use the same troubleshooting technique, maybe you'll find a way too. I used Python debugger, like this:

```
def javascript_catalog_pdb(*args, **kwargs):
    import pdb
    pdb.set_trace()
    return javascript_catalog(*args, **kwargs)

url_patterns = [
    url(r'^jsi18n/$', javascript_catalog_pdb, js_info_dict, name='javascript-catalog'),
    ...
]
```

Then using PDB, I stepped into `javascript_catalog`, until I got to the line:

```
catalog, plural = get_javascript_catalog(locale, domain, packages)
```

I then experimented with different values for `domain` and `packages`, right there in the debugger, until I discovered the values I needed.
