九、用户模块
7、取消收藏机构
用户取消收藏机构应该在operations下实现。
（1）、url
from django.urls import path from .views import * app_name = 'operations' urlpatterns = [ path('user_ask', user_ask, name='user_ask'), path('user_love', user_love, name='user_love'), path('user_comment', user_comment, name='user_comment'), path('user_delete', user_delete, name='user_delete'), ]
（2）、前端页面
用户收藏的机构是由后端传递过去的，前端通过for循环遍历，将机构存放在dl中，这时候我们需要知道用户取消哪个机构。
所以将class='delete jsDeleteFav_org'的div中的data-favid直接存为机构的id。
<script> $(function () { $('.delete').click(function () { // prop()用来取自带属性的值或设置值， attr()用来去元素自定义的属性的值或设置值 var loveid = $(this).attr('data-favid'); // 如果天生的属性用 prop() var lovetype = 1; var obj = $(this); $.ajax({ type: 'GET', url: '{% url 'operations:user_delete' %}', data:{ loveid:loveid, lovetype:lovetype }, success(callback){ if (callback.status == 'ok'){ alert(callback.msg); //拿到点击对象的祖先节点当中有类名是des的对象 obj.parents('.des').remove() //拿到dl标签,并移除 }else{ alert(callback.msg) } } }) }) }) </script>
同时在调试的过程中，发现二级base中的一个js对当前页面有影响，为了保留原本的js，切不影响当前页面，在二级base中挖坑，将这个js包含，当前页面填坑重写。置空。

（3）、视图函数
# operations/view.py def user_delete(request): loveid = request.GET.get("loveid", '') lovetype = request.GET.get('lovetype', '') if loveid and lovetype: love = UserLove.objects.filter(love_id=int(loveid), love_type=int(lovetype), love_man=request.user, love_status=True) if love: love[0].love_status = False love[0].save() return JsonResponse({ 'status': 'ok', 'msg': '取消成功' }) else: return JsonResponse({ 'status': 'fail', 'msg': '取消失败' }) return JsonResponse({ 'status': 'fail', 'msg': '取消失败' })
