Setup

Before using library, you need setup some things in your django project, please follow this steps

1. Setup all required variables in your settings.py

from django.utils.translation import gettext_lazy as _
# Mention the lanuage with respective language code which you will be using in your project
LANGUAGES = [
    ('en', _('English')),
    ('fr', _('French')),
   ('es', _('Spanish')),
   ('de',_('German')),
   ('en-IN',_('English (India)'))
    # Add more languages as needed

]

LANGUAGE_CODE = 'en-in' # default =  'en'

LOCALE_PATHS = [
    os.path.join(BASE_DIR, 'locale'),  # Optional, default path './locales' folder
]

TIME_ZONE = 'UTC'

USE_I18N = True

USE_L10N=True

LANGUAGES_BIDI = [
    'he', 'ar',  # Add right-to-left languages if required
]

# Below mention localization of number system according to current language code of project

THOUSAND_SEPARATOR=','
DECIMAL_SEPARATOR='.'
USE_THOUSAND_SEPARATOR=True
NUMBER_GROUPING=(3,2,0)

2. Create a JSON file with translation data in the following format:

{
  "fr": {
    "Hello": "Bonjour",
    "Goodbye": "Au revoir"
  },
  "de": {
    "Hello": "Hallo",
    "Goodbye": "Auf Wiedersehen"
  },
  "es": {
    "Hello": "Hola",
    "Goodbye": "Adiós"
  }
}

3. Import and use the create_files() function from the translation_file_generator module:

    from mt_django_i18n.json_to_po import create_translator_files
    from django.utils.translation import gettext as _

    create_files(json_file_path,project_name,target_lang)

1. json_file_path = This parameter represent file path for translation
2. project_name = Name of project
3. target_lang = Lagunages which language file should be converted in binary format file i.e .mo files

Example

views.py

from mt_i18n.json_to_po import create_files
import os
from django.utils.translation import gettext as _
# Create your views here.


def blog(request):
    'hello':_('Hello'), # this mark to value stored in _('') are to translated 
    if not (os.path.exists("locale") and os.path.isdir("locale")):
        
        os.mkdir('locale')
        create_files("translator.json","blog",['fr', 'de', 'es'] )
    

Templates - HTML pages

• The static text to be translated should be marked throught {% trans Hello world! %} or via variable format as mention below

    <p>{{example}}</p>
    <p>{% trans %}</p>

• For localization

                    {% load l10n %}
                    {% localize on %}
                    <tr>
                      <td><h6 class="text-muted">Category</h6></td>
                      <td> <h6 class="fw-bold">
                        {{my_currency|localize}}
                      </h6></td>
                    </tr>

                    <tr>
                      <td><h6 class="text-muted">Number</h6></td>
                      <td> <h6 class="fw-bold">{{my_number|localize}}
                      </h6></td>
                    </tr>

                    <tr>
