Flask

问题 I chose to use a server-side session management with Flask using Flask-Session. I store the data using filesystem and as expected, these files are stored under a /flask_session folder in my config directory. Here is how I set this up in my __init__.py # __init__.py from flask_session import Session [...] app.config['SESSION_TYPE'] = 'filesystem' app.config['SECRET_KEY'] = config.SECRET_KEY sess = Session() sess.init_app(app) As expected, session files generated & stored under /flask_session ▾

问题 I'm working on a web application using Flask in Python. I have small function in my application that calculates some values in the background and displays the result on the web page via a flashing message. Everything is displaying and working fine but it requires page reloading to get the flashing message. I want to display messages without reloading page. I heard that I can do that with js, but I'm not familiar with js. If you have any ideas or suggestion I would appreciate. There is my code

问题 Other than the ability to automatically generate an interactive documentation for our API using Swagger UI, are there any real advantages of using Flask-RESTplus over Flask-RESTful? 回答1: update When reading this accepted answer, consider that there is Flask-RESTX which is a fork of Flask-RESTPlus that is maintained, as an alternative option. I am aware of the fact that this answer is probably too late, but it still might be helpful in the future. According to https://github.com/noirbizarre

问题 I'm new to Flask, and having some issues setting up a very basic Flask app. Right now, I'm trying to get the user to submit a form on the homepage and then save that form to a SQL database.

问题 I am using Flask and Flask-RESTful to build a REST API. Within this API some of my resources contain url relations to other resources. When performing POST requests to these resources I am finding that I am needing the inverse of Flask's url_for() function to parse the incoming url. For example, a POST to https://www.example.com/buildings may contain the following json: { "address": "123 Lyall St", ... "owner": { "href": "https://www.example.com/users/21414512" }, "tenant": { "href": "https:/
