Question

我想通过“anno”订购模板的一些元素，但我不知道如何或在哪里（如果来自视图或模板）。我试过了，但我认为我错过了其他的东西。请问你能帮帮我吗...？？？！！！感谢...

my models.py:

class Anno( models.Model ):
    anno = models.CharField( max_length=4 )
    def __unicode__(self):
        return self.anno
    class Meta:
        verbose_name_plural = "Anni"

class Sequel_Film( models.Model ):
    saga = models.CharField( max_length=30 )
    def __unicode__(self):
        return self.saga
    class Meta:
        verbose_name_plural = "Sequels"

class Film( models.Model ):
    titolo = models.CharField( max_length=39 )
    trama = models.TextField( max_length=1000 )
    locandina = models.FilePathField( path="C:/Users/Federico/Google Drive/Umore/apps/Database/static/Film/Locandina", recursive=True )
    copertina = models.FilePathField( path="C:/Users/Federico/Google Drive/Umore/apps/Database/static/Film/Copertina", recursive=True )
    trailer = models.FilePathField( path="C:/Users/Federico/Google Drive/Umore/apps/Database/static/Film/Trailer", recursive=True )
    data_inserimento = models.DateField( null=True, verbose_name="data d'inserimento" )
    anno = models.ForeignKey( Anno )
    durata = models.IntegerField( max_length=5 )
    attori = models.ManyToManyField( Attore )
    registi = models.ManyToManyField( Regista )
    studi = models.ManyToManyField( Studio )
    umori = models.ManyToManyField( Umore )
    generi = models.ManyToManyField( Genere_Film )
    sequels = models.ManyToManyField( Sequel_Film )
    def __unicode__(self):
        return self.titolo + " " + self.trama
    class Meta:
        verbose_name_plural = "Films"

my views.py：

def film(request, id):
    film = get_object_or_404( Film, pk=id )
    return render_to_response('Film.html', { 'film': film })

我的模板Film.html：

  {% for sequel in film.sequels.all %}
    {% for film in sequel.film_set.all %}
    {% endfor %}
  {% endfor %}

但是模板中的标签之间有......

  {% for sequel in film.sequels.all %}
  {% for film in sequel.film_set.all %} #{% for sequel_film in sequel.ordered_film_set %}

我如何使用{{sequel_film}} ???对不起，但我不明白......

您可以为模型添加帮助：

class Sequel_Film( models.Model ):
    ...

    def ordered_film_set(self):
        return self.film_set.all().order_by('anno__anno')

在模板中：

{% for sequel in film.sequels.all %}
    {% for sequel_film in sequel.ordered_film_set %}
        {{sequel_film}}
    {% endfor %}
{% endfor %}

使用_set.all时的订单模板
