Django完善图片管理功能

一删除图片

1 修改mysite/image/views.py

# 删除图片功能
@login_required(login_url='/account/lobin/')
@require_POST
@csrf_exempt
def del_image(request):
    image_id = request.POST['image_id']
    try:
        image = Image.objects.get(id=image_id)
        image.delete()
        return JsonResponse({'status':"1"})
    except:
        return JsonResponse({'status':"2"})

2 配置URL

from django.conf.urls import url
from . import views

urlpatterns = [
    # 展示图像列表
    url(r'^list-images/$', views.list_images, name="list_images"),
    # 上传图片
    url(r'^upload-image/$', views.upload_image, name='upload_image'),
    # 删除图片
    url(r'^del-image/$', views.del_image, name='del_image'),
]

3 编写mysite/templates/image/list_images.html

{% extends "article/base.html" %}
{% load staticfiles %}
{% block title %}图像{% endblock %}

{% block content %}
<div>
    <button type="button" class="btn btn-primary btn-lg btn-block" onclick="addImage()">添加图片</button>
    <div style="margin-top:10px;">
    <table class="table table-hover">
        <tr>
            <td>序号</td>
            <td>标题</td>
            <td>图片</td>
            <td>操作</td>
        </tr>
        {% for image in images %}
        <tr>
            <td>{{ forloop.counter }}</td>
            <td>{{ image.title }}</td>
            <td>{{ image.image }}</td>
            <td><a nane="delete" href="javascript:" onclick="del_image(this, {{ image.id }})"><span class="glyphicon glyphicon-trash" style="margin-left:20px;"></span></a></td>
        </tr>
        {% empty %}
        <p>还没有图片，请点击上面的按钮添加图片</p>
        {% endfor %}
    </table>
    </div>
</div>

<script src="{% static 'js/jquery.js' %}"></script>
<script src="{% static 'js/layer.js' %}"></script>
<script type="text/javascript">
function addImage(){
    var index=layer.open({

                layer.close(index);
                window.location.reload();
              } else {
                layer.msg("图片无法获取，请更换图片");
              }
            },
          });
        });
      },
    });
}

function del_image(the, image_id){
  var image_title = $(the).parents("tr").children("td").eq(1).text();
  layer.open({
    type: 1,
    skin: "layui-layer-rim",
    area: ["400px", "200px"],
    title: "删除图片",
