通过AJAX删除导致CSRF令牌丢失或不正确

标签: django

Django 1.10

DetailView呈现" detail.html"。

在" detail.html"我放置"删除"按钮。换句话说,我希望用户能够按"删除"完全来自" detail.html"当他们看到物体本身时。

所以,按下"删除"我通过AJAX调用FrameDelete。

您能否帮我理解为什么会收到错误: CSRF令牌丢失或不正确。

class Frame(models.Model):

    title = models.CharField(max_length=100,
                             null=False,
                             blank=False,
                             default="",
                             unique=True,
                             verbose_name="Заголовок")
    def get_delete_url(self):
        return reverse("frame:frame_delete", kwargs=self.get_kwargs())

class FrameDelete(ActionDeleteMixin, DeleteView):
    model = Frame
    success_url = reverse_lazy("empty")
    template_name = 'general/ajax/ajax_confirm_delete.html'

class ActionDeleteMixin():
    def get_context_data(self, **kwargs):
        context = super(ActionDeleteMixin, self).get_context_data(**kwargs)
        context["action"] = self.object.get_delete_url()
        return context

JS

    function post_delete(){
        $.ajax({
            method: 'POST',
            url: "{{ object.get_delete_url }}",
            success: redirect_to_frame_list,
            error: fail
        });
    }

function fail(jqXHR, textStatus, errorThrown){
    debugger;   
}

ajax_confirm_delete.html

{% block content %}
    <form action="{{ action }}" method="post">{% csrf_token %}
        <p>Are you surely want to delete "{{ object }}"?</p>
        <input id="confirm" type="submit" value="Confirm" />
    </form>
{% endblock %}

在浏览器中检查Chrome中的元素时:

<form action="/frame/18/delete/" method="post"><input type="hidden" name="csrfmiddlewaretoken" value="bHZxf62Oa9WrapuacCm8gLVNlY2nJHllfwqPsAHoPO0RS8z8NnhMSv5tnIFQZKPP">
        <p>Are you surely want to delete "18: Michael's news"?</p>
        <input id="confirm" type="submit" value="Confirm">
    </form>

**

在浏览器中停止在失败函数的调试器断点处

    CSRF token missing or incorrect.

  <p>In general, this can occur when there is a genuine Cross Site Request Forgery, or when
  <a
  href="https://docs.djangoproject.com/en/1.10/ref/csrf/">Django's
  CSRF mechanism</a> has not been used correctly.  For POST forms, you need to
  ensure:</p>

  <ul>
    <li>Your browser is accepting cookies.</li>

    <li>The view function passes a <code>request</code> to the template's <a
    href="https://docs.djangoproject.com/en/dev/topics/templates/#django.template.backends.base.Template.render"><code>render</code></a>
    method.</li>

    <li>In the template, there is a <code>{% csrf_token
    %}</code> template tag inside each POST form that
    targets an internal URL.</li>

    <li>If you are not using <code>CsrfViewMiddleware</code>, then you must use
    <code>csrf_protect</code> on any views that use the <code>csrf_token</code>
    template tag, as well as those that accept the POST data.</li>

    <li>The form has a valid CSRF token. After logging in in another browser
    tab or hitting the back button after a login, you may need to reload the
    page with the form, because the token is rotated after a login.</li>
  </ul>

  <p>You're seeing the help section of this page because you have <code>DEBUG =
  True</code> in your Django settings file. Change that to <code>False</code>,
  and only the initial error message will be displayed.  </p>

  <p>You can customize this page using the CSRF_FAILURE_VIEW setting.</p>

您应该添加csrf_exempt或生成csrf token with ajax
