How to render template in Flask interval using apscheduler?

Question

Flask

@app.route('/')
def main():
    data = get_content()
    return render_template('article.html', data=data)

get_content() should, conditionally, look at the data every 2 minutes. After that, you need to render the template.

scheduler.add_job(main, trigger='interval', seconds=120)

Gives an error message

AttributeError: 'NoneType' object has no attribute 'app'

Perhaps it makes sense to write a second function that will call get_content, and put main itself in the add_listener of the same apscheduler. But, in theory, AttributeError will not go anywhere.
A completely different option is to add a client to Vue, but I don’t want to install vue-cli at all. The application itself is very small. Although this seems to be the only correct option.

Answer 1

As a result, I still wrote a client in Vue and organized an interval request to the server.
