双语模特

Question

根据__unicode__，request.session['django_language']是否有办法返回西班牙语或英语？我应该以不同的方式设计我的模型，还是这是标准的做事方式？

class Tip(models.Model):
    '''A small random tip for users to see on the login page'''
    en_text = models.CharField(max_length=500)
    es_text = models.CharField(max_length=500)

    def __unicode__(self):
        pass

然后从视图到模板......

try:
    tip = Tip.objects.order_by('?')[0]
except:
    tip = None

- ＆GT;

<p>{{ tip }}</p>

Answer 1

我不确定这是最好的方法，但我遇到了类似的情况并做了以下事情：

class Image(models.Model, TranslatedModelMixin):
     artifact = models.ForeignKey(Artifact)
     caption = models.CharField(max_length=500, null=True, blank=True)
     caption_fr = models.CharField(max_length=500, null=True, blank=True)
     image = models.ImageField(upload_to='artifacts/images')

     language_code = 'en'
     translated_fields = ['caption']

     def __unicode__(self):
         return u'Image for %s' % self.artifact.name


 class TranslatedModelMixin(object):
     """
     Given a translated model, overwrites the original language with
     the one requested
     """

     def set_language(self, language_code):
         if language_code == 'en':
             return

         self.language_code = language_code

         for field in self.translated_fields:
             translated_field_key = field + '_' + language_code
             translated_field = getattr(self, translated_field_key)
             setattr(self, field, translated_field)

         return

因此，如果我想要法语模型数据，我只需image.set_language('fr')，然后在我的模板中我可以{{ image.caption }}获取翻译版本。我不会使用__unicode__在模板中显示模型。
