Session was a cookie designed to be erased when the browser was closed and was a method for exchanging it: Rails Tutorial Note-What is a Rails Session?

Abstract: What is a Rails Session?

I noticed from the time of Progate that I was next to session

As you progress through the Rails tutorial

Something like a variable called a session Login maintenance mechanism using cookies to supplement it I had a feeling of being moody, but in reality

Both

--Mechanism for making HTML stateful --Both are stored in cookies by default

However

--session was implemented by Rails, but login maintenance by cookie was implemented later. --session has a time limit (default?), While the latter is permanent (intentionally designed)

I used a time-limited cookie A mechanism for making HTML stateful called a session ** The developer did not intend ** to implement the session method in Rail.

Note: What is a Rails Session?

HTML is stateless by nature and has no continuity persistence

Session is a mechanism for making stateless HTML stateful

Is it a ** mechanism like Cookie **? I did it in Chapter 8 of the Rails tutorial

If you think In the first place, Rails stores session in cookie by default.

I checked it with Chrome's developer tools I have a _sample_app_session that seems to be for the Rails tutorial sample_app

Furthermore, the expiration date is ** "at the end of the browser session" **. This was the reason for the ephemeral feel imprinted in the Rails tutorial.

What is session in Rails?

session is a method, not a variable Since it was automatically generated by the process of rails new sample_app

I understood that ** it was used as a matter of course **

For example, if Rails new hoge is installed with Rails installed, a Rails application will be created, and if rails g controller sessions in the hoge directory will generate SessionsController that inherits ApplicationController, it will be written as session [: hoge] from the beginning.
