Django：用ManyToManyField循环遍历两个for循环

Question

大家好，我在这个问题上苦苦挣扎，谷歌搜索了这个硬核。

我正在开发一个图像库，每个相册输出，当点击一个屏幕覆盖显示图像库。艰苦的工作已经在JavaScript中已经完成了在画廊中显示的每个图像，所以我只需要由给定的图像路径：

{{ images.content }} 

下面是我的文件，我用我的Django项目。

对此的帮助将会很棒。

manage.py

from django.db import models 

PHOTO_PATH = 'media_gallery' 

class Gallerys(models.Model): 
    title = models.CharField(max_length=30, help_text='Title of the image maximum 30 characters.') 
    slug = models.SlugField(unique_for_date='date', help_text='This is automatic, used in the URL.') 
    date = models.DateTimeField() 

    class Meta: 
     verbose_name_plural = "Image Galleries" 
     ordering = ('-date',) 

    def __unicode__(self): 
     return self.title 

class Images(models.Model): 
    title = models.CharField(max_length=30, help_text='Title of the image maximum 30 characters.') 
    content = models.FileField(upload_to=PHOTO_PATH,blank=False, help_text='Ensure the image size is small and it\'s aspect ratio is 16:9.') 
    gallery = models.ManyToManyField(Gallerys) 
    date = models.DateTimeField() 

    class Meta: 
     verbose_name_plural = "Images" 
     ordering = ('-date',) 

    def __unicode__(self): 
     return self.title 

import models 
from django.contrib import admin 

class ImagesAdmin(admin.ModelAdmin): 
    list_display = ('title', 'date') 

class GallerysAdmin(admin.ModelAdmin): 
    list_display = ('title', 'date', 'slug') 

admin.site.register(models.Images, ImagesAdmin) 
admin.site.register(models.Gallerys,GallerysAdmin) 

views.py

from django.http import HttpResponse 
from notices.models import Notices 
from django.shortcuts import get_object_or_404 
from django.shortcuts import render_to_response 
from gallery.models import * 
from navigation.models import * 

# when the galleries page is requested, all image galleries are listed by date created with the latest first, 
# each gallery displayed contains a javascript tag containing an index of images separated by ';' 
def galleries(request): 
    gallery = Gallerys.objects.all() 
    images = Images.objects.all() 

    return render_to_response('galleries.html', {'Galleries': gallery, 'Images': images}) 

galleries.html

 {% for galleries in Galleries %} 
      <h1>{{ galleries.title }}</h1> 
      {% for images in galleries.gallery.all %} 
       <h2>{{ images.content }}</h2> 
      {% empty %} 
       none 
      {% endfor %} 
     {% endfor %} 

当我通过迭代：

<h2>{{ images.content }}</h2> 

我什么也没得到，我哪里出错了？

谢谢！

在Galleries对象中没有称为gallery的属性。

用户的默认反向M2M访问images_set

{% for images in galleries.images_set.all %} 

{% endfor %}
