Question

我正在尝试使用django rest框架来轻松处理一些模型作为restful资源。这是我的代码：

Django: 1.7.1

Django REST Framework: 2.4.4

jQuery: 2.1.1

# models.py

class DocumentNodeTemplate(MPTTModel):
    """

    """
    document_template = models.ForeignKey(
        DocumentTemplate,
        related_name="nodes",
        verbose_name="Document template"
    )
    parent = TreeForeignKey(
        'self',
        null=True, blank=True,
        related_name='children'
    )
    section_template = models.ForeignKey(
        'SectionTemplate',
        related_name="node_templates",
        verbose_name="Section template"
    )

    def __unicode__(self):
        return  self.section_template.name

    def get_class(self):
        type = self.section_template.type
        return import_string(type)


# serializers.py

class DocumentNodeTemplateSerializer(serializers.ModelSerializer):
    class Meta:
        model = DocumentNodeTemplate
        fields = ('document_template', 'parent', 'section_template')


# views.py

class DocumentNodeTemplateAPIView(CreateAPIView, RetrieveUpdateDestroyAPIView):
    queryset = DocumentNodeTemplate.objects.all()
    serializer_class = DocumentNodeTemplateSerializer


<!-- HTML (section - admin's change form customization)-->
<fieldset class="module aligned">
    <h2>{{ node_fieldset_title }}</h2>
    <div class="form-row document-nodes">
        <div
        style="width: 100%; min-height: 450px;" id="general-container"
        data-document_model="{{ document_model }}"
        >
            <form id="changelist-form" action="" method="post" novalidate>{% csrf_token %}
                <div id="tree-container">
                    <div id="tree"
                         data-url="{{ tree_json_url }}"
                         data-save_state="{{ app_label }}_{{ model_name }}"
                         data-auto_open="{{ tree_auto_open }}"
                         data-autoescape="{{ autoescape }}"
                            >
                    </div>
                    <div class="add-node">
                        <a href="/admin/document/{{ model_name }}/add/?_to_field=id&document_id={{ object_id }}" class="add-another"
                            onclick="return showCustomAddAnotherPopup(event, this);">
                            <img src="/sitestatic/admin/img/icon_addlink.gif" width="10" height="10"
                                 alt="Add another node"> Add another node
                        </a>
                    </div>
                    <ul class='node-custom-menu'>
                        <li data-action="delete">Delete node</li>
                    </ul>
                </div>
            </form>
            <div id="node-container">
                <h3 id="node-name"></h3>
                <br/>

                <div id="node-content"></div>
            </div>
        </div>
    </div>
</fieldset>


// javascript 
var performCRUDaction = function(action, api_url, callback) {
var csfrtoken = $('input[name="csrfmiddlewaretoken"]').prop('value');
var _reloadNodeTree = function () {
    window.nodeTree.tree('reload');
}
var _performAction = function () {
    jQuery.ajax({
            type: actionType,
            url: api_url,
            data: { 'csrfmiddlewaretoken': csfrtoken },
            success: function () {
                console.log("action " + action + " successfully performed on resource " + api_url);
                _reloadNodeTree();
            },
            error: function () {
                console.log("action " + action + " failed on resource " + api_url);
            }
        });
    }


    var actionType,
        documentModel = null;
    var nodeDataObj = {};
    switch (action) {
        case "delete":
            actionType = "DELETE";
            break;
        case "update":
            actionType = "PUT";
            break;
        case "create":
            actionType = "POST";
            break;
        case "retrieve":
            actionType = "GET";
            break;
    }
    _performAction();
    callback();
}

我没有发布所有代码，无论如何当触发ajax调用时，我得到403错误：

任何人都遇到过相同或类似的问题，可以提供帮助吗？

Answer 1

您应该通过进入历史记录选项卡然后清除浏览数据来删除所有Cookie和其他网站和插件数据以及缓存的图像和文件...另一个选项是使用@csrf_exempt装饰器和基于类的视图。
