我有一个模式,可以显示用户的照片,在该模式中,该照片带有一个垃圾桶图标,供用户删除照片,然后,他单击该垃圾桶,就会出现另一个模式,询问他是否确定他要删除照片。 并确认照片已删除。 问题在于您总是要删除第一张照片,而不是删除模态中的照片。 如果我在图库中间的任何照片中都单击并单击,则该照片会以模态打开,即我选择的照片,但是在尝试删除时,请始终删除图库的第一张照片

答案 0 :(得分:1)
您删除模式的id
属性不是唯一的,因此$('#delete')
始终引用相同的模式。
您可以为模型创建唯一的ID,然后将数据属性添加到.pop2
按钮中。这样的事情应该起作用:
perfil.html
{% for photo in photos %}
...
<a class="pop2" data-target="delete-{{ for.counter }}" href="{% url 'delete' photo.id %}" >
...
<div class="modal fade" id="delete-{{ for.counter }}">
...
modalconfirmedelete.js
$(function() {
$('.pop2').on('click', function() {
$($(event.delegateTarget).data('target')).modal('show');
});
});
另一方面,我强烈建议更改您的delete
视图,以仅对POST
个请求执行删除操作:
views.py
def delete(request, id):
if request.method != 'POST':
return HttpResponseNotAllowed(['POST'])
photos = Photo.objects.get(id=id)
photos.delete()
return redirect('sistema_perfil')
您可以使用表单和按钮来代替<a href="{% url 'delete' photo.id %}"
:
perfil.html
<form action="{% url 'delete' photo.id %}" method="POST">
{% csrf_token %}
<submit class="btn bg-danger">...
