These stacks are implemented as LocalStack objects in global memory in Flask. Once Flask has a Response object that represents the route function's response, it does a few things with it. Among them, it passes it to any defined after_request handlers, which gives the application a chance to insert or modify headers, change the body or the status code, or even replace the response with a completely new one if it so desires. g is an object provided by Flask. It is a global namespace for holding any data you want during a single app context. For example, a before_request handler could set g.user , which will be accessible to the route and other functions.

Unsure what that g object is? It’s something in which you can store information for your own needs, check the documentation of that object (g) and the Flask에서 SQLite 3 사용하기 for more information.

In Flask, this is called a context-local . Context locals are similar to but ultimately different than Python's thread-local implementation for storing data that is specific to a thread.

route ('/') def index (): When the Flask application handles a request, it creates a Request object based on the environment it received from the WSGI server. Because a worker (thread, process, or coroutine depending on the server) handles only one request at a time, the request data can be … Raise exception if an unexpected attr is set, a “controlled” flask.g. In Flask 0.9 this property was called request_globals_class but it was changed in 0.10 to app_ctx_globals_class because the flask.g object is not application context scoped. Here I'm storing the form in g.search_form, so then when the before request handler ends and Flask invokes the view function that handles the requested URL, the g object is going to be the same, and will still have the form attached to it.
