在Flask中绘制叶贴图

Question

我创建了一个flask应用程序，它映射了几个变化的变量。每次浏览器窗口刷新时，地图上的一个元素都应该更改

假设我的叶映射是map

开始时，我找到了map._repr_html_()对象。这在几天内运行良好，然后在一夜之间停止

我没有对代码做任何更改，现在我只得到了html的文本表示，地图应该在哪里

有什么想法吗

看起来是这样的,；相当长。对不起

“app.py”中使用的代码如下所示：

要创建地图，请执行以下操作：

map=folium.Map(zoom_level=0)
folium.Marker([userlat,userlon]).add_to(map)
folium.Marker([latitude,longitude],icon=folium.Icon(icon='cloud')).add_to(map)

要将地图渲染到.html，请执行以下操作：

return render_template('index.html',**pass_data, map=map._repr_html_())

要在html中调用映射，请执行以下操作：

{{ map }}

Answer 1

通过在Python对象的调用中添加“safe”一词，找到了一个解决方案

{{ map | safe }}
