Django照片應用程序不顯示

Question

我使用這個輕型鳥教程製作照片應用程序。

問題是，我上傳的圖片。不會顯示在頁面上。 我從來沒有顯示在以前的Django的圖片，我認爲這個問題是與配置

我的models.py

from django.db import models 
    from django.contrib.auth.models import User 
    from django.contrib import admin 
    from string import join 
    import os 
    from PIL import Image as PImage 
    from mysite.settings import MEDIA_ROOT 

    class Album(models.Model): 
     title = models.CharField(max_length=60) 
     public = models.BooleanField(default=False) 
     def __unicode__(self): 
      return self.title 
     def images(self): 
      lst = [x.image.name for x in self.image_set.all()] 
      lst = ["<a href='/media/%s'>%s</a>" % (x, x.split('/')[-1]) for x in lst] 
    return join(lst, ', ') 
     images.allow_tags = True 
    class Tag(models.Model): 
     tag = models.CharField(max_length=50) 
     def __unicode__(self): 
      return self.tag 

    class Image(models.Model): 
     title = models.CharField(max_length=60, blank=True, null=True) 
     image = models.FileField(upload_to="images/") 
     tags = models.ManyToManyField(Tag, blank=True) 
     albums = models.ManyToManyField(Album, blank=True) 
     created = models.DateTimeField(auto_now_add=True) 
     rating = models.IntegerField(default=50) 
     width = models.IntegerField(blank=True, null=True) 
     height = models.IntegerField(blank=True, null=True) 
     user = models.ForeignKey(User, null=True, blank=True) 
     def save(self, *args, **kwargs): 
      """Save image dimensions.""" 
      super(Image, self).save(*args, **kwargs) 
      im = PImage.open(os.path.join(MEDIA_ROOT, self.image.name)) 
      self.width, self.height = im.size 
      super(Image, self).save(*args, ** kwargs) 

     def size(self): 
      """Image size.""" 
      return "%s x %s" % (self.width, self.height) 

     def __unicode__(self): 
      return self.image.name 

     def tags_(self): 
      lst = [x[1] for x in self.tags.values_list()] 
      return str(join(lst, ', ')) 

     def albums_(self): 
      lst = [x[1] for x in self.albums.values_list()] 
      return str(join(lst, ', ')) 

     def thumbnail(self): 
      return """<a href="/media/%s"><img border="0" alt="" src="/media/%s" height="40" /></a>""" % (
                   (self.image.name, self.image.name)) 
thumbnail.allow_tags = True 
     def __unicode__(self): 
      return self.image.name 

    class AlbumAdmin(admin.ModelAdmin): 
     search_fields = ["title"] 
     list_display = ["title"] 

我views.py

from django.http import HttpResponseRedirect, HttpResponse 
    from django.shortcuts import get_object_or_404, render_to_response 
    from django.contrib.auth.decorators import login_required 
    from django.core.context_processors import csrf 
    from django.core.paginator import Paginator, InvalidPage, EmptyPage 
    from django.forms import ModelForm 
    from mysite.settings import MEDIA_URL 

    from photo.models import * 

    def main(request): 
     """Main listing.""" 
     albums = Album.objects.all() 
     if not request.user.is_authenticated(): 
      albums = albums.filter(public=True) 

     paginator = Paginator(albums, 10) 
     try: page = int(request.GET.get("page", '1')) 
     except ValueError: page = 1 

     try: 
      albums = paginator.page(page) 
     except (InvalidPage, EmptyPage): 
      albums = paginator.page(paginator.num_pages) 

     for album in albums.object_list: 
      album.images = album.image_set.all()[:4] 

     return render_to_response("photo/list.html", dict(albums=albums, user=request.user, 
      media_url=MEDIA_URL)) 

     class TagAdmin(admin.ModelAdmin): 
      list_display = ["tag"] 

     class ImageAdmin(admin.ModelAdmin): 
      search_fields = ["title"] 
      list_display = ["__unicode__", "title", "user", "rating", "size", "tags_", "albums_", 
    "thumbnail", "created"] 
      list_filter = ["tags", "albums", "user"] 

      def save_model(self, request, obj, form, change): 
       obj.user = request.user 
       obj.save() 

     admin.site.register(Album, AlbumAdmin) 
     admin.site.register(Tag, TagAdmin) 
     admin.site.register(Image, ImageAdmin) 

Answer 1

好吧，問題是爲什麼圖片沒有顯示。您調用不正確的並覆蓋圖像的路徑。記住，你已經把函數模型中的縮略圖，以便在你的模板，你必須只放：

<ul> 
    {% for album in albums.object_list %} 
    <div class="title">{{ album.title }} ({{ album.image_set.count }} images)</div> 
     <ul> 
      {% for img in album.images %} 
       {{img.thumbnail}} 
      {% endfor %} 
     </ul> 
    {% endfor %} 
</ul> 

這是正確的，但我的問題是，當我測試時，允許標籤功能沒有任何影響，因此輸出一個鏈接，而不是圖像。所以我修改了它並獲得了圖像顯示。

{% for img in album.images %} 
    <a href="{{MEDIA_URL}}{{ img.image}}"> 
     <img border="0" alt="" src="{{MEDIA_URL}}{{ img.image}}" /> 
    </a> 
{% endfor %}
