python - django permissions and contenttypes translations -

i've been using django-modeltranslation translate models in django while. straightforward , works on apps i've been developing, all model translated content gets inserted forms final user.

eg: inputs: content, content_en, content_pt, ...

i have build application need translate 'built-in' model strings generated django, 'auth.permission.name' or 'contenttypes.contenttype.name' and add them translation django.po files.

i came solution works fine,

which uses post_migration signals create file lists of ugettext_lazy elements, new strings, new contenttype.name example, added 'django.po' dynamically , loaded database.

yet, bit weird having create file ugettext calls

in order register strings, didn't find way of registering , adding them dynamically django.po file, need help

here's have done:

1. created app named 'tools', last 1 on installed_apps, migrations naturally last ones called. app not have models, runs migrations, has django-modeltranslation translation.py file , application config post_migration signal call.

# translations.py  modeltranslation.translator import translator, translationoptions django.contrib.auth.models import permission django.contrib.contenttypes.models import contenttype  class permissiontranslationoptions(translationoptions):     fields = ('name',)  class contenttypetranslationoptions(translationoptions):     fields = ('name',)  translator.register(permission, permissiontranslationoptions) translator.register(contenttype, contenttypetranslationoptions) 

2. running 'manage.py makemigrations' creates migrations on 'auth' , 'contenttypes' applications 'name_*' fields.

3. app has application config has post_migrate signal

# __init__.py  default_app_config = 'apps.tools.config.systemconfig' 

# config.py  django.apps import appconfig django.db.models.signals import post_migrate apps.tools.translations.exporter import make_translations apps.tools.translations.importer import load_translations   def run_translations(sender, **kwargs):      # creates translations     make_translations()      # loads the translations db     load_translations()   class systemconfig(appconfig):      name = 'apps.tools'     verbose_name = 'tools'      def ready(self):         # call post migration operations         post_migrate.connect(run_translations, sender=self) 

4. make_translations() called after migrations , generates file lists of uggettext_lazy calls.

this bit change. need create file?

# exporter  import os django.contrib.auth.models import permission django.contrib.contenttypes.models import contenttype django.utils import translation django.contrib.contenttypes.management import update_all_contenttypes   # todo  # has got way  def make_translations():     # lets go default     translation.activate("en")     update_all_contenttypes()      try:         f = open(os.path.join(os.path.realpath(os.path.dirname(__file__)), 'translations.py'), 'w')          # write file         f.write("from django.utils.translation import ugettext_lazy _\n\n")          # permissions lazy text         f.write('permissions = {\n')         perm in permission.objects.all().order_by('id'):             f.write('    "'+str(perm.id)+'": _("'+perm.name+'"),\n')         f.write('}\n\n')          # content types lazy text         f.write('content_types = {\n')         content in contenttype.objects.all().order_by('id'):             f.write('    "'+str(content.id)+'": _("'+content.name+'"),\n')         f.write('}\n\n')          # closing file         f.close()          # importing file registered ugettext_lazy         try:             apps.tools.translations import translations         except:             print('could not import file')             pass     except:         print('could not create file')         pass 

the above results in file this:

from django.utils.translation import ugettext_lazy _  permissions = {     "1": _("can add permission"),     "2": _("can change permission"),     "3": _("can delete permission"),     "4": _("can add group"),   ... }  content_types = {     "1": _("group"),     "2": _("user"),     "3": _("permission"),     "4": _("content type"),     "5": _("session"),   ... } 

5. running 'makemessages' add strings 'django.po' files, yet, post_migration signal not stop here, , loads existing compiled strings in database

# importer  django.contrib.auth.models import permission django.contrib.contenttypes.models import contenttype django.conf import settings django.utils import translation   def load_translations():     try:         apps.tools.translations.translations import permissions, content_types     except:         # file not exists         print('translations not loaded')         return      # each language     lang in settings.languages:          # activate language         translation.activate(lang[0])          # loading translated permissions         all_permissions = permission.objects.all()         permission in all_permissions:             permission.name = unicode(permissions[str(permission.id)])             permission.save()          # loading translated content_types         all_contenttypes = contenttype.objects.all()         contenttype in all_contenttypes:             contenttype.name = unicode(content_types[str(contenttype.id)])             contenttype.save() 

how can replace 'make_translations()' without creating file , register strings ugettext_lazy?

thanks help
