Render a Jinja template stored on an FTP server

I have some templates on an FTP server, and my app is running on another server. Can I use render_template to render a template at an FTP link?

Yes, one can use render_template() function with the template files on another server. Create a loader that gets the remote template from the link. In this example, I use an HTTP server, but you can use an FTP server by changing the URL passed to the UrlLoader constructor.

from flask import Flask, render_template
from jinja2 import BaseLoader, TemplateNotFound
from urllib import urlopen
from urlparse import urljoin


class UrlLoader(BaseLoader):
    def __init__(self, url_prefix):
        self.url_prefix = url_prefix

    def get_source(self, environment, template):
        url = urljoin(self.url_prefix, template)
        try:
            t = urlopen(url)
            if t.getcode() is None or t.getcode() == 200:
                return t.read().decode('utf-8'), None, None
        except IOError:
            pass
        raise TemplateNotFound(template)

app = Flask(__name__)
app.jinja_loader = UrlLoader('http://localhost:8000/')


@app.route('/')
def root():
    return render_template('hello.html')

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