Django中的“惰性翻译”方法的相关使用

from django.utils.translation import ugettext_lazy

class MyThing(models.Model):
  name = models.CharField(help_text=ugettext_lazy('This is the help text'))

# This is fine: putting a unicode proxy into a unicode string.
u"Hello %s" % ugettext_lazy("people")

# This will not work, since you cannot insert a unicode object
# into a bytestring (nor can you insert our unicode proxy there)
"Hello %s" % ugettext_lazy("people")
