Answer 1

You could save your generated html with folium_map.save('templates/map.html'). Then you can use jinja2 to {% include "map.html" %}. The generated html does not render a map when wrapped in div tags as indicated, if encapsulation is necessary consider using iframes or custom folium templates.

myapp
├── run.py
└── templates
    ├── index.html
    └── layout.html

run.py

from flask import Flask, render_template
import folium

app = Flask(__name__)

@app.route('/')
def index():
    start_coords = (46.9540700, 142.7360300)
    folium_map = folium.Map(location=start_coords, zoom_start=14)
    folium_map.save('templates/map.html')
    return render_template('index.html')

if __name__ == '__main__':
    app.run(debug=True)

layout.html

  


  
{% block head %}{% endblock %}
  {% block body %}{% endblock %}

index.html

{% extends "layout.html" %}
{% block title %} Test {% endblock %}
{% block head %} {{ super() }} {% endblock %}
{% block body %}
    {% include "map.html" %}
{% endblock %}
