Django-debug-toolbar: 使用 Django 调试工具栏 1.8 时的堆栈溢出（在 1.7 中工作正常）

创建于 2017-06-01  ·  11评论  ·  资料来源: jazzband/django-debug-toolbar

下午好，当我尝试在 Wagtail CMS 提供的路由上使用 DJDT 1.8 时遇到堆栈溢出错误。 相同的路由/页面适用于 DJDT 1.7。 我正在运行 Django 1.11.2 和 Wagtail 1.10.1。 这是跟踪：

Fatal Python error: Cannot recover from stack overflow.

我现在可以运行 1.7，但是我不知道从哪里开始深入研究这个问题。 任何想法、建议或希望的解决方案？ 提前致谢。

在 Django 1.8 中使用 DDT 1.8 时，我可以确认同样的问题。

patchman-daniel picture patchman-daniel 于 2017-06-06

我见过同样的问题——它是在使用指定模板的 StreamField 块时触发的。 将该模板添加到SKIP_TEMPLATE_PREFIXES调试工具栏配置是一种解决方法。 我记得（虽然是前一段时间），根本问题是块对象在其__str__方法中呈现模板，这导致调试工具栏的 TEMPLATES 面板中的无限递归。

我在 DDT 1.8、Django 1.11.2 和 Wagtail 1.10.1 上也经历过同样的事情。
用 Python 3.6、3.6.1 和 3.7a 复制它

经过一番调查，在panel.py:128中创建了一个无限循环，在value可以是一个StructValue字符串表示实际上是一个模板渲染，它触发了一个信号template_rendered .

我已经对它进行了猴子修补以使其适用于使用 Wagtail 的人。 补丁在这里：

https://github.com/FlipperPA/django-debug-toolbar/commit/e68cfa509566bf5332c37f03c0fd9753a873d491

我不希望这应该是 PR，因为它是特定于 Wagtail 的。

FlipperPA picture FlipperPA 于 2017-06-23

另一个修补程序是从调试工具栏中排除StructBlock使用的模板。 例如

class MyStructBlock(StructBlock):
    ...
    class Meta:
        ...
        template = 'myblocks/structblock.html'

并添加到settings.py文件中：

DEBUG_TOOLBAR_CONFIG = {
    'SKIP_TEMPLATE_PREFIXES': ('django/forms/widgets/', 'admin/widgets/', 'myblocks/structblock.html'),
}

来自SKIP_TEMPLATE_PREFIXES DDT 文档：

收集呈现的模板和上下文时，将跳过以这些字符串开头的模板。 默认情况下会跳过基于模板的表单小部件，因为面板 HTML 可以轻松地增长到数百兆字节，其中包含许多表单字段和许多选项。

为我工作。

我们在 Django 调试工具栏 1.8 和 django-floppyforms 中遇到了这个问题，并以类似的方式解决了这个问题：

DEBUG_TOOLBAR_CONFIG = {
    'SKIP_TEMPLATE_PREFIXES': (
        'django/forms/widgets/',
        'admin/widgets/',
        'floppyforms/'
    ),
    'DISABLE_PANELS': {
        'debug_toolbar.panels.redirects.RedirectsPanel',
        'debug_toolbar.panels.redirects.TemplatesPanel'
    },
}

我们还决定默认禁用 TemplatesPanel，因为它严重减慢了页面速度。 与 Django 调试工具栏 1.7 相比，页面加载速度慢了三倍。

在https://github.com/wagtail/wagtail/pull/3738 中修复 - 我认为这可以关闭，因为这是一个 Wagtail 问题。

也会影响django-el-pagination==3.1.0 ，将'el_pagination/',到SKIP_TEMPLATE_PREFIXES有所帮助。
