Django：如何顯示與模型給出的單個關聯的數據列表.ManyToManyField

我是新手，也許這是一個愚蠢的問題，所以先謝謝你提前援助。我想在模板中看到由某位導演執導的電影列表。以下文件是我迄今爲止創建的，請在文件中添加更正。Django：如何顯示與模型給出的單個關聯的數據列表.ManyToManyField

這裏的models.py：

from django.db import models 

class Genere_Film(models.Model): 
    genere = models.CharField(max_length=25) 
    def __unicode__(self): 
     return self.genere 
    class Meta: 
     verbose_name_plural = "Generi_Film" 

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

class Durata(models.Model): 
    durata = models.CharField(max_length=5) 
    def __unicode__(self): 
     return self.durata 
    class Meta: 
     verbose_name_plural = "Durata" 

class Attore(models.Model): 
    nome = models.CharField(max_length=30) 
    cognome = models.CharField(max_length=30) 
    foto = models.CharField(max_length=100) 
    data_inserimento = models.DateField(null=True, verbose_name="data d'inserimento") 
    def __unicode__(self): 
     return self.nome + " " + self.cognome + " " + self.foto 
    class Meta: 
     verbose_name_plural = "Attori" 

class Regista(models.Model): 
    nome = models.CharField(max_length=30) 
    cognome = models.CharField(max_length=30) 
    foto = models.CharField(max_length=100) 
    data_inserimento = models.DateField(null=True, verbose_name="data d'inserimento") 
    def __unicode__(self): 
     return self.nome + " " + self.cognome + " " + self.foto 
    class Meta: 
     verbose_name_plural = "Registi" 

class Studio(models.Model): 
    nome = models.CharField(max_length=30) 
    foto = models.CharField(max_length=100) 
    data_inserimento = models.DateField(null=True, verbose_name="data d'inserimento") 
    def __unicode__(self): 
     return self.nome #+ " " + self.foto 
    class Meta: 
     verbose_name_plural = "Studi" 

class Trailer(models.Model): 
    trailer = models.CharField(max_length=100) 
    data_inserimento = models.DateField(null=True, verbose_name="data d'inserimento") 
    def __unicode__(self): 
     return self.trailer 
     class Meta: 
      verbose_name_plural = "Trailers" 

class Film(models.Model): 
    titolo = models.CharField(max_length=39) 
    trama = models.CharField(max_length=1000) 
    locandina = models.CharField(max_length=100) 
    copertina = models.CharField(max_length=100) 
    trailer = models.ForeignKey(Trailer) 
    data_inserimento = models.DateField(null=True, verbose_name="data d'inserimento") 
    anno = models.ForeignKey(Anno) 
    durata = models.ForeignKey(Durata) 
    attori = models.ManyToManyField(Attore) 
    registi = models.ManyToManyField(Regista) 
    studi = models.ManyToManyField(Studio) 
    generi = models.ManyToManyField(Genere_Film) 
    def __unicode__(self): 
     return self.titolo + " " + self.trama + " " + self.locandina + " " + self.copertina 
    class Meta: 
     verbose_name_plural = "Film"

這裏的urls.py：

from django.conf.urls.defaults import * 

urlpatterns = patterns('',  
    (r'^Film$', 'Database.views.film'), 
)

這裏的views.py：

from django.shortcuts import render_to_response 
from django.template import RequestContext 
from models import * 

def film(request): 
    film = Film.objects.all() 
    return render_to_response('Film.html', { 'film': film, })

這裏的template.html：

enter code here

您需要主管ID傳遞給url：

urlpatterns = patterns('',  
    url(r'^film/$', 'Database.views.film'), 
    url(r'^film/director/(?P<director_id>\d+)/$', 'Database.views.film', name="films_by_director"), 
)

然後通過它查看過濾：

def film(request, director_id=None): 
    film = Film.objects 
    if director_id: 
     director = get_object_or_404(Regista, id=director_id) 
     film = film.filter(registi=director) 
    else: 
     film = film.all() 
    return render_to_response('Film.html', { 'film': film, })

而且在模板列表，如：

<ul> 
{% for f in film %} 
    <li>{{ f }}</li> 
{% endfor %} 
</ul>
