Django - 在單獨頁面上加載完整圖像

Question

我一直在試圖在圖像縮略圖上放置一個超鏈接，這將使用戶獲得完整尺寸的圖像。但我不斷收到錯誤。

這裏

，因爲它表明，scribblemedia是亂塗

models.py

class ScribbleMedia(models.Model): 
    media = models.FileField(upload_to=get_file_path) 
    def __unicode__(self): 
     return self.media 
    def find_typecheck(self): 
     filename = self.media.name 
     try: 
      ext = filename.split('.')[-1] 
      imgcheck=['jpg','jpeg','png','gif','tiff','bmp'] 
      if ext in imgcheck : 
       chk='image' 
      else: 
       chk='other' 
     except Exception: 
      chk='not supported' 
     return chk 

class Scribble(models.Model): 
    title = models.CharField(max_length=120) 
    body = models.TextField() 
    user = models.ForeignKey(User) 
    media = models.ForeignKey(ScribbleMedia) 
    def __unicode__(self): 
     return u'%s, %s' % (self.user.username, self.media) 

views.py

@login_required 
def image_page(request,pk): 
    img=get_object_or_404(ScribbleMedia,pk=pk) 
    image=img.media 
    variables= RequestContext(request,{ 
    'image': image 
    }) 
    return render_to_response('image_page.html',variables) 

urls.py

(r"^image/(\d+)/$", image_page), 

image_page一個ForeignKey .html

{% if image %} 
    <img src= {{ image.url }} /> 

這是圖像的縮略圖可在頁面

scribble_page.html

{% if scribble.media.media %} 
       {% if scribble.media.find_typecheck == 'image' %} 
        {% thumbnail scribble.media.media.url "700x500" crop="center" as im %} 
          <a href="/image/{{ scribble.media.pk }}/" target="_blank"><img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}"></a> 
        {% endthumbnail %} 
       {% else %} 
        do something else 
       {% endif %} 
      {% endif %} 

它不斷給我下面的錯誤：

TemplateSyntaxError在/圖像/ 2/ 未封閉標籤'if'。尋找其中一個：elif，else，endif

Answer 1

您的scribble_page.html中的if語句沒問題。你需要關閉你的image_page.html模板中的if塊...

{% if image %} 
    <img src="{{ image.url }}" /> <!-- Also note the added quotations... --> 
{% endif %} <!-- This is the line you need to add -->
