I have built my own completely fresh templates for sign in and registration, rather than using their provided ones. Following the documentation, I have placed these templates at templates/flask_user/login.html , templates/flask_user/register.html and so on. I have also set USER_UNAUTHENTICATED_ENDPOINT = "login"

问题 I'm running a simple test site on PythonAnywhere using Flask. When I run the script, the initial site (index.html) appears, and everything seems fine. However, when I click on any of the links (like signup.html), I get a 404 error: Not Found The requested URL was not found on the server.

问题 How would I use a decorator on a route to HTML escape its output. That is, how do I write the html_escape function here: @app.route('/') @html_escape def index(): return '<html></html>' (I feel like there should be an extension for this and other simple decorators) 回答1: Flask has its own escape , doc: flask.escape so, you can: from flask import escape @app.route('/') def index(): return escape("<html></html>") if you insist on using decorator: from functools import wraps from flask import
