Initialize called more than once?

Rails
1

Hi,

In my test case below, it seems that ‘initialize’ is called everytime
‘hello’ is called. Is this by design, a bug, or my pilot error?

class FooController < ApplicationController

    def initialize
        print "\n initialize \n"
    end

    def hello
        print "\n hello \n"
    end
end

I thought initialize will be called exactly once when the controller is
constructed and not when an action is executed.

Thanks for your help and sorry if duplicate,

-Danny

On every request, a controller object is created. When the controller
object is created, the initialized function is called.

Well the controler gets created every time a action is called, HTTP is a
stateless protocol : )

If you’re in dev mode, I believe the controller would be reloaded
with every request so you would see initialize called for each
invocation of hello.

This is correct, it’s just that a new FooController is being created
(instantiated, whatever) for each request.

Controllers get re-constructed on every invocation of every action, no
matter if you’re in development, test, or production mode.
