Insert the folium maps into the jinja template

I want to insert follium map into the jinja template.

run.py

from flask import Flask, render_template

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()
    return render_template('index.html', folium_map=folium_map)


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

template/index.html - jinja template for Flask

{% extends "layout.html" %}
{% block title %}Test{% endblock %}
{% block head %}
{{ super() }}
{% endblock %}
{% block body %}
**<div><!--Folium map here-->{{ folium_map }}</div>**
{% endblock %}

My site shows current line:

<folium.folium.Map object at 0x00000000069D5DA0>

But I need map that generate method follium_map.save('map.html') in this div block.

How can I do this?

Solution

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.

    folium_map = folium.Map(location=start_coords, zoom_start=14)

index.html

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

    {% include "map.html" %}
