Django複製對象

Question

我試圖在我的白板內部實現評論功能。該功能允許學生對彼此的圖片進行評論。

我有一個應用程序，學生可以創建虛擬白板並在白板內張貼與作業相關的圖片。

當用戶單擊以查看特定圖片下的評論時。該評論確實出現在該特定圖片上，但所有圖片上都出現相同的評論，這也不是假設。

我一直在想辦法實現評論功能，這是我唯一的想法。 我怎麼能解決這個重複的問題，因爲我的「M一直在試圖想出一個辦法來的圖片與註釋關聯。

我的白板。 HTML

{% if picture %} 
<ul> 
    {% for pet in picture %} 


     {% if pet.image %} 

    <a href ="{% url world:LikePicture pet.id %}"><br> 
     <img src= "{{ pet.image.url }}" style="cursor:pointer"></a> 
<br> 
    </a> 
</li> 
     {% endif %} 

<br> 
<a href="{% url world:CommentCreator pet.id %}">View Comment</a><br/> 
     {% for c in comment %} 
      <br>{{ c.body }}</li> 
      <br>{{ c.created}}</li> 
      <br>{{ c.user}}</li> 
{% endfor %} 
{% endfor %} 
       </ul> 
{% endif %} 

我views.py

def Boat(request ,animal_id): 
     if not request.user.is_authenticated(): 
      return HttpResponseRedirect(reverse('world:LoginRequest')) 

    picture = Picture.objects.filter(whiteboard=animal_id) 

    return render(request,'whiteboard.html',{'picture':picture}) 

def CommentCreator(request,picture_id): 
    p = Picture.objects.get(pk=picture_id) 
    comment = Comment.objects.filter(picture=p) 
    Whiteboard = WhiteBoard.objects.get(whiteboard=p) 
    the_id = board.id 
    picture = Picture.objects.filter(whiteboard=the_id) 

    return render(request,'whiteboard.html',{'picture':picture,'comment':comment}) 

我的models.py

class WhiteBoard(models.Model): 

    user = models.ForeignKey(User) 
    name = models.CharField(max_length=100) 
    picture = models.OneToOneField('Picture',related_name='picture',blank=True,null=True)

    image = models.FileField(upload_to="images/",blank=True) 
    description = models.TextField() 
    is_primary = models.BooleanField(default=False) 

    def __unicode__(self): 
     return self.description 
class Comment(models.Model): 
    created = models.DateTimeField(auto_now_add=True) 
    user = models.ForeignKey(User) 
    body = models.TextField() 
    picture = models.ForeignKey(Picture)
