Django - Preventing translation of available language names in template

Question

I have my available languages in settings.py

LANGUAGE_CODE = 'en'
LANGUAGES = (
    ('fr', _('French')),
    ('en', _('English')),
)

When i loop in my template, I think it is the expected behavior that django gives me the translated names via {{ lang.1 }}. But i don't want lang names to be translated so i have changed my settings.py as below:

LANGUAGES = (
        ('fr', 'Francais'),
        ('en', 'English'),
    )

I am still getting translated lang names. Do you have an idea? Does {% get_available_languages as languages %} template tag automatically translates the list items? If so how can i use untranslated language names while looping in available languages?

---- EDIT ---

I have checked the code of get_available_languages template tag of django. I think it is translated here:

class GetAvailableLanguagesNode(Node):
    def __init__(self, variable):
        self.variable = variable

    def render(self, context):
        context[self.variable] = [(k, translation.ugettext(v)) for k, v in settings.LANGUAGES]
        return ''

Maybe i have to write my own template tag...

if i write ('en', 'test'), for example it works and gives 'test' as expected... — ratata, Feb 25 '15 at 15:39
Seems like you have answered your own question. You should just write your own template tag, or access settings.LANGUAGES directly. — Håken Lid, Feb 10 '16 at 14:11

No Hacks, this time

According to the translation documentation you can use the available language tools either in the template or in the python code.

In the template, using the get_language_info template tag:

{% get_language_info for "pl" as lang %}

Language code: {{ lang.code }}<br />
Name of language: {{ lang.name_local }}<br />
Name in English: {{ lang.name }}<br />
Bi-directional: {{ lang.bidi }}
Name in the active language: {{ lang.name_translated }}

which can be combined with other tags and build a mechanism that allows you to change languages:

{% for lang_code, lang_name in languages %}  
   {% if lang_code != LANGUAGE_CODE %}      
     {% get_language_info for lang_code as lang_info %}
     {% language lang_code %}                            
     {% url request.resolver_match.url_name as no_slug %}
     {% url request.resolver_match.url_name slug=object.slug as yes_slug %}  
     <p>Link to: {% firstof yes_slug no_slug %} Local name: {{ lang_info.name_local }}</p>
     {% endlanguage %}
   {% endif %}
 {% endfor %}

In this thread the same result is achieved in the view.

Otherwise, you can use get_language_info in your code as follows:

>>>from django.utils.translation import get_language_info
>>>li = get_language_info('en')
>>>print(li)
{'bidi': False, 'code': 'en', 'name': 'English', 'name_local': 'English'}

and use it in the context of the following example:

from django.utils import translation

def welcome_translated(language):
    cur_language = translation.get_language()
    try:
        translation.activate(language)
        text = translation.ugettext('welcome')
    finally:
        translation.activate(cur_language)
    return text

if i write ('en', 'test'), for example it works and gives 'test' as expected

Thank you! This idea brought forward the following ~~solution~~ hack:

LANGUAGES = (
        ('fr', 'Francais'),
        ('en', ' English'),
    )

Notice the space added before the word English.

I had the same issue (wanting the language names in their own translation) and simply redefined the languages variable in views before passing it to the template:

   from django.utils.translation import get_language_info
   languages = [(lang[0], get_language_info(lang[0])['name_local'] for lang in settings.LANGUAGES]

That basically allows to have quickly a variable of language codes and names in their own translation, namely :

   [('en', 'English'), ('fr', 'Français')]

I guess the same line would do the job in a custom template tag. Hope it helps !
