Question

我必须从Django db中删除记录使用Jquery / Ajax。你能救我吗？

django / views function

def owner(request, identifer):
    x = get_object_or_404()
    if request.method == "DELETE":
        x.objects.delete()

ajax代码：

 $(document).ready(function() {
       $(".delete").click(function(){
            var id_number = this.id;
            alert(id_number);
            $.ajax({
               type: 'DELETE',
               url: 'owner/{item.id}/',
               data: 'identifer='+id_number,
               success: function(){
                  if(data) {alert("Success!")}
            });
         });
  });

您必须为数据类型定义

    <script>
        function deleteCommand(svCommandId) {
            var url = $('#service_command_form').attr('action') + svCommandId;
            $.ajax({
                url: url,
                type: "DELETE",
                dataType: "json",
                beforeSend: function (xhr) {
                    xhr.setRequestHeader("X-CSRFToken", '{{ csrf_token }}');
                },
                success: function () {
                    $('#service_command_' + svCommandId).remove();
                    addMessage("Deleted data successfully");
                },
                error: function () {
                    addMessage("Delete failed!");
                }
            });

您没有解释出现了什么问题，但是如果我查看您的代码，您似乎需要更改您的查看代码：

def owner(request, identifer):

    try:
        x = <YourModelName>.objects.get(id=identifier)

    except <YourModelName>.DoesNotExist:

        return error message here ...

    x.delete()

    return success message here ...

您的JS代码中也有错误，您没有使用双括号：

url: "owner/{{item.id}}/"

但更好的是你不应该对你的网址进行硬编码，使用{％url％}模板标签会更好

url: "{% url 'name-of-owner-view' item.id %}"

使用ajax删除Django数据库中的记录
