You can add authentication to your Flask app with the Flask-Login package. a flask decorated with the picture of a donkey carrying a cross. # Serve app at APPLICATION_ROOT for localhost development. English Introduction Allowing users to log in to your app is one of the most common features you will add to your web applications. # Load a dummy app at the root URL to give 404 errors. # app.config = index():įrom gi import DispatcherMiddleware # to the config - I'm not exactly sure how! Temporary policy: Generative AI (e.g., ChatGPT) is banned. Stack Overflow at WeAreDevelopers World Congress in Berlin. I'll copy the code here for posterity: "Serve a Flask app on a sub-url during localhost development."Īpp.om_object(_name_) # I think this adds APPLICATION_ROOT Im learning Blueprints in Flask and wrote the following short script to test how urls can be served from the blueprint: from flask import Flask. app/main/views.py: Blueprint with application routes from. Flask's DispatcherMiddleware to the rescue! Example 77 shows the routes of the application updated to be in the blueprint. However, if you would like this to work during development while running the Flask app in debug, take a look at this gist. So, I believe that a valid answer to this is: the prefix should be configured in the actual server application that you use when development is completed. In order to avoid a 404 custom re-implementation, please from werkzeug.exceptions import NotFound and then raise NotFound() if the check fails. In addition, you might want to check the submitted prefix against some rules, and return a 404 if the check fails. NB: It is worth nothing that it is possible to use a variable in the prefix (for example by setting it to /), and then process this prefix in the functions you decorate with your If you do so, you obviously have to declare the prefix parameter in your decorated function(s). You can use it like this: app = Flask(_name_)Īpp.route = prefix_route(app.route, '/your_prefix') Return route_function(mask.format(prefix, route), *args, **kwargs)Īrguably, this is somewhat hackish and relies on the fact that the Flask route function requires a route as a first positional argument. The mask argument is a `format string` formatted with, in that order: Rather it is a blueprint of how to construct or extend. Return "The URL for this page is '):ĭefines a new route function with a prefix. A Blueprint object works similarly to a Flask application object, but it is not actually an application. Sub-mounted inside of another WSGI containerĪssuming that you are going to run this application inside of a WSGI container (mod_wsgi, uwsgi, gunicorn, etc) you need to actually mount, at that prefix the application as a sub-part of that WSGI container (anything that speaks WSGI will do) and to set your APPLICATION_ROOT config value to your prefix: app.config = index(): The answer depends on how you are serving this application.
