python - Is it possible to order a Django Model using the active language? -


i'm working on django 1.5.1 , i'm wondering following question: possible define ordering in model on translatable field, using django-transmeta , using active language user accessing admin?

so far, achieved use translated field , order using default language, not active one, call get_language() returns default defined in settings.py if call method meta class (or modeladmin class).

here code i'm working on, , help:

class startuptype(models.model):      __metaclass__ = transmeta      name = models.charfield(_("name"), max_length=30, unique=true)     slug = models.slugfield(_("slug"), max_length=30, unique=true, editable=false)      class meta:          verbose_name = _("startup type")         verbose_name_plural = _("startup types")         translate = (             "name",         )         ordering = [             "name_" + language_code,         ]

according documentation can define get_ordering() method use dynamic order:

# admin.py django.contrib import admin .models import startuptype  class startuptypeadmin(admin.modeladmin):     def get_ordering(self, request):         language_code = request.language_code[:2]         return ('name_%s' % language_code,)  admin.site.register(startuptype, startuptypeadmin)

this works using get_language() instead of request.language_code.

if still not correct language, make sure added locale middleware after session middleware in settings.py, e.g.:

middleware_classes = (      'django.middleware.common.commonmiddleware',      'django.contrib.sessions.middleware.sessionmiddleware',      'django.middleware.locale.localemiddleware',      'django.middleware.csrf.csrfviewmiddleware',      'django.contrib.auth.middleware.authenticationmiddleware',      'django.contrib.messages.middleware.messagemiddleware',      'django.middleware.clickjacking.xframeoptionsmiddleware',  )

edit: added alternative define dynamic ordering on model.

if want set ordering on model class, seems tad bit more complicated, best come with:

from django.db import models django.db.models.options import options django.utils.translation import get_language django.utils.translation import ugettext_lazy _  transmeta import transmeta, get_real_fieldname   class translatedoptions(options):     @property     def ordering(self):         lang = get_language()[:2]         return [get_real_fieldname(f, lang) f in self.orig_ordering]      @ordering.setter     def ordering(self, value):         self.orig_ordering = value   class transmetaordering(transmeta):     def __new__(cls, name, bases, attrs):         new_class = super(transmetaordering, cls).__new__(cls, name, bases, attrs)         options = translatedoptions(none)         k, v in new_class._meta.__dict__.iteritems():             setattr(options, k, v)         new_class._meta = options         return new_class   class startuptype(models.model):     __metaclass__ = transmetaordering      name = models.charfield(_("name"), max_length=30)     slug = models.slugfield(_("slug"), max_length=30, editable=false)      class meta:         verbose_name = _("startup type")         verbose_name_plural = _("startup types")         translate = (             "name",         )         ordering = (             "name",         )

this replace startuptype._meta (an object of type django.db.models.options.options) new object of type translatedoptions expose ordering dynamic property.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
