#Flask blueprint update code
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 Flask's DispatcherMiddleware to the rescue! 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). Then the blueprint is registered with the application when it is available in the factory function. Rather than registering views and other code directly with an application, they are registered with a blueprint. You can use it like this: app = Flask(_name_)Īpp.route = prefix_route(app.route, '/your_prefix') A Blueprint is a way to organize a group of related views and other code. Services/DAO Singleton Design Pattern: A pattern I have found that works very well in a Flask app is the services/dao (database access object) singleton pattern. 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. Blueprints are a great way to organize your routes and a must use for large applications. The mask argument is a `format string` formatted with, in that order: Return "The URL for this page is '):ĭefines a new route function with a prefix. You can call this instead of ablueprint. 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(): Fractions from The NOAAESRL Carbon Cycle cooperative Global Air Sampling Network,(/ccg/co2/flask/event/,(19682007),version:(20080724.). 1 Answer Sorted by: 2 I wrote a small snippet to add a jsonroute method to an already existing blueprint (instance of the Blueprint class). The answer depends on how you are serving this application.
