Apply HTTP basic auth just to the admin interface

flask_admin_http_basic_auth.py

# The docs say "Unfortunately, there is no easy way of applying HTTP Basic Auth just to your admin interface."
# But this is not true :)
# First:
# pip install flask-admin
# pip install flask-basicauth

from flask_admin import Admin
from flask_admin.contrib.sqla import ModelView
from flask_admin.base import expose, AdminIndexView
from flask_basicauth import BasicAuth

auth = BasicAuth()

class SecureModelView(ModelView):
    def is_accessible(self):
        return auth.authenticate()

    def inaccessible_callback(self, name, **kwargs):
        return auth.challenge()


class SecureAdminIndexView(AdminIndexView):
    @expose()
    @auth.required
    def index(self):
        return super(SecureAdminIndexView, self).index()


admin = Admin(index_view=SecureAdminIndexView())
# admin.add_view(SecureModelView(Order, db.session))
