Flask G Before_Request at Steven Payton blog

Flask G Before_Request. For example you could use 'g' to set a flag at the beginning of a request and handle it at the end. Before each request, before_request() functions are called. G is an object provided by flask. It is a global namespace for holding any data you want during a single app context. The g module or flask.g is provided by flask which is used as a global object while developing a flask app by developers to store. These functions will be called before the before_request() functions. The function can modify the values captured from the matched. It is often used in request decorators like @app.before_request, @app.after_request and @app.teardown_request. Flask.before_request() is a decorator used in flask web applications to register a function that will be executed before each request is handled by. When testing flask applications, you might call preprocess_request() to ensure before_request functions are executed before your test code. It can also be used for resource management like managing database connections. If one of these functions return a value, the other functions are skipped.
