html render_template not working

here's the code:

@app.route('/sentdex') def sentdex(): return render_template ("index.html", title = "hi", paragraph = "the para")

I'm using pythonanywhere.com. I have two variables in my index.html page, title and paragraph

the message I'm getting is 'internal server error'

here's the index.html file contents:

<!DOCTYPE html> <html> <head></head>

<body class = 'body'>
    <body>
        <h3>{{ title }}</h3>
        <p>{{ paragraph }}</p>
    </body>

</body>

</html>

I have html tags but they aren't showing up here

Just a bit of sanity check:

  • You have render_template imported?
  • Your index.html template is in the templates/ directory?
  • You created a Flask app named app? Usually you do this with something like app = Flask(__name__)

OK, so let's try some more stuff :)

Is your app running in debug mode? app.debug = True or app.run(debug=True)

it wasn't, I added it to the end of the app and the error message changed, now it says:

"Something went wrong :-(

OK, so, what's in the site and error logs?

I don't know much about PythonAnywhere. Surely they have some server/error logs available if they suggest you check them. If not, maybe start here for turning on logging for your app?
