Flask-Admin link back to main site

Question

Is there any way to modify the home button url link on the flask-admin admin top panel so that I redirect back to a main site?

I can add a link in a custom.html page eg:

{% extends 'admin/master.html' %}
{% block body %}
    <a href="{{ url_for('main.home') }}">Home</a>
{% endblock %}

But this is hidden away inside the custom page. I'd prefer a top-bar link out of admin.

Easiest way is to add a menu link and leave the admin home page alone (you might want to add a dashboard or suchlike in the future):

from flask_admin.menu import MenuLink

# Create admin
admin = Admin(app, name='Admin', url='/')
admin.add_view(ImageView(model=Image, session=db.session, category='Database', name='Images'))
# Add custom link to public website home page
admin.add_link(MenuLink(name='Public Website', category='', url=url_for('main.home')))

Note, url_for needs to be called within a Flask application context. For example, if using the Flask application factory pattern, this would look something like the following:

def create_app(config):

    app = App('app')

    #  setup config

    #  setup blueprints 

    #  setup Flask-Admin

    from app.admin import create_admin
    from app.admin.configure import configure_admin
    with app.app_context():
        admin = create_admin(app=app)
        configure_admin(app, admin)

    #  more stuff

   return app

__init__.py in app.admin module

def create_admin(app=None):
    return Admin(app, template_mode='bootstrap3')

configure.py in app.admin module

def configure_admin(app, admin):

    # setup views

    # add link to home page

    admin.add_link(MenuLink(name='Public Website', category='', url=url_for('home.HomeView:index')))
