我不确定在用户通过之前的 html 表单提交输入后如何让 html/js 在浏览器上工作...我似乎到处都在寻找,并且有很多类似的解决方案问题,但我可以没有人去工作!
谢谢!
此回复是为了增加像我一样在尝试在 Django 模板中渲染 Folium 地图时也遇到此问题的其他人的 google 覆盖率。
请参阅每个代码块内的注释,了解如何按预期渲染地图。
map = folium.Map(location=[df['latitude'].mean(),
df['longitude'].mean()],tiles="cartodbpositron",zoom_start=12)
map.save("map.html")
# {'my_map': map} will output the object, which is what you are seeing
# to rectify this we need to turn it into an iframe which
# the template can then render.
context = {'my_map': map} # change to {'my_map': map._repr_html_()}
return render(request, 'my_map.html', context)

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
# after making the change in our views.py this will return the html but
# the template will not render it as expected because it is being escaped.
# You must declare it 'safe' before it will be rendered correctly.
{{ my_map }} # change to {{ my_map | safe }}
