In order to really include folium into custom django template you have to render your figure first before adding it to context (This will recursivly load all parts of the map into the figure). Afterwards in your template, you have to access header, html and script parts of figure seperatly by calling their render function. Additionally, those parts have to marked as "safe" by django template tag in order to allow html insertion. See example below.
Example:
views.py:
import folium
from django.views.generic import TemplateView
class FoliumView(TemplateView):
template_name = "folium_app/map.html"
def get_context_data(self, **kwargs):
figure = folium.Figure()
m = folium.Map(
location=[45.372, -121.6972],
zoom_start=12,
tiles='Stamen Terrain'
)
m.add_to(figure)
folium.Marker(
location=[45.3288, -121.6625],
popup='Mt. Hood Meadows',
icon=folium.Icon(icon='cloud')
).add_to(m)
folium.Marker(
location=[45.3311, -121.7113],
popup='Timberline Lodge',
icon=folium.Icon(color='green')
).add_to(m)
folium.Marker(
location=[45.3300, -121.6823],
popup='Some Other Location',
icon=folium.Icon(color='red', icon='info-sign')
).add_to(m)
figure.render()
return {"map": figure}
templates/folium_app/map.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

{{map.header.render|safe}}
