Dash 数据表不会在 django-plotly-dash 中的页面上呈现
Dash datatable wont render on page in django-plotly-dash
我正在使用 django_plotly_dash 创建一个 Web 应用程序，这是一个将 Django、Plotly 和 Dash 组合到一个包中的模块。我遇到一个问题，我可以尝试加载一些作为破折号应用程序一部分的破折号数据表，但它们永远不会在页面上呈现。页面卡在“加载中...”，如下所示：
如您所见，页面中间（从主页开始）是应该加载破折号数据表的位置，但屏幕卡在“正在加载...”上。
从启动应用程序后的日志输出来看，似乎与 Django 没有找到正确的静态文件有关。下面是输出：

如果需要更多信息来解决此问题，请告诉我。
通过将 settings.py 的 PLOTLY_DASH 变量中的 "serve locally" 键更改为 False 解决了这个问题。留下这个问题并为将来可能遇到相同问题的任何人回答。请将您的 settings.py 与 django-plotly-dash.

我正在使用 django_plotly_dash 创建一个 Web 应用程序，这是一个将 Django、Plotly 和 Dash 组合到一个包中的模块。我遇到一个问题，我可以尝试加载一些作为破折号应用程序一部分的破折号数据表，但它们永远不会在页面上呈现。页面卡在“加载中...”，如下所示：
如您所见，页面中间（从主页开始）是应该加载破折号数据表的位置，但屏幕卡在“正在加载...”上。
从启动应用程序后的日志输出来看，似乎与 Django 没有找到正确的静态文件有关。下面是输出：

如果需要更多信息来解决此问题，请告诉我。
通过将 settings.py 的 PLOTLY_DASH 变量中的 "serve locally" 键更改为 False 解决了这个问题。留下这个问题并为将来可能遇到相同问题的任何人回答。请将您的 settings.py 与 django-plotly-dash.
