我一直在尝试将 django paginator 实现到我的白板应用程序中，这样我就可以将图片分成不同的页面。

当我尝试在不同页面之间移动时会出现问题。我将每个页面限制为 1 个对象并上传了几张图片以测试页面之间的分页是否有效，但是当我尝试使用分页方法在不同页面之间移动时，它没有响应.

我一直在研究和测试通过 django 分页文档解决这个问题的方法，我认为问题出在我的模板中的分页模块方法上。

我的观点.py

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

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

    paginator = Paginator(picture,1)
    page = request.GET.get('page')
    try:
             picture = paginator.page(page)

         except PageNotAnInteger:
             picture = paginator.page(1)
         picture = paginator.page(paginator.num_pages)


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

我的船.html

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


        {% if pet.image %}

    <br>
        <img src= "{{ pet.image.url }}" </a>
 <br>
    </a>
 </li>
        {% endif %}

 <br>
 <a href="{% url world:CommentCreator pet.id %}">View Comment</a>  <a href="{% url      world:LikePicture pet.id %}">Like</a><br/>
 {% for c in picture %}
     {% ifequal c.picture.id pet.id %}

 <br>{{ c.body }}</li>
 <br>{{ c.created}}</li>
 <br>{{ c.user}}</li>
     {% endifequal %}
 % endfor %}

 {% endfor %}
 </ul>
 {% endif %}
 <a href="{% url world:PictureCreator %}">Add Pictures to your board</a><br/>

 {% if number %}
 {{number}}
 {% endif %}
 <a href="{% url world:Profile %}">Return back to Profile</a><br/>

 <br><br><br><br><br>

 <div class="pagination">
     <span class="step-links">
         {% if picture.has_previous %}
             <a href="?page={{ picture.previous_page_number }}">previous</a>
         {% endif %}

         <span class="current">
             Page {{ picture.number }} of {{ picture.paginator.num_pages }}.
         </span>

         {% if picture.has_next %}
             <a href="?page={{ picture.next_page_number }}">next</a>
         {% endif %}
     </span>
 </div>

我的模块的一部分

class Picture(models.Model):
    user = models.ForeignKey(User)
    board = models.ForeignKey(Board,blank=False,null=False,related_name='board')
    image = models.FileField(upload_to="images/",blank=True)
    description = models.TextField()
    is_primary = models.BooleanField(default=False)

    def __unicode__(self):
        return self.description
