Translate values dict-like in Django templates

In my Model I define choices along the lines of:

LANG_CHOICES = (
    ("Englisch", (
        (u"en-gb", u"England"),
        (u"en-us", u"United States of America"),
    ), )

T开发者_如何学JAVAhe field is defined as:

lang_source = models.CharField(max_length=5, choices=LANG_CHOICES, default="en-gb")

Naturally, in my template I'd want to display the human-readable value, i.e.

{{ object.lang_source }}

should not print "en-gb" (or the respective value) but rather "England".

What is the most elegant way to accomplish this? (Besides in the View importing a dict from the Model and manually translating the value.)

Try:

object.get_lang__source_display()

Documentation:

• http://docs.djangoproject.com/en/1.1/ref/models/instances/#django.db.models.Model.get_FOO_display

{{ object.get_lang_source_display }}

should work.

Using two underscores in a row when defining field name is forbidden, because of the way django filters QuerySets: http://docs.djangoproject.com/en/dev/topics/db/models/#field-name-restrictions
