Code to be run on server start up

[Mike Witt]

In Rails 4.2, is there a place where I can put code that I want to be
called immediately after the rails server starts up (as opposed to when
an HTTP request comes in). In other words, I want my code executed
right after I do a "rails server" command or a "heroku restart."

As one simple example, suppose I wanted to maintain an item in the
database that would simply count system reloads. Where would that code
go?

Initializers are called *during* startup; would that do?

I'm not sure. Would I have access to the database, either through
ActiveRecords or ?

Pardon my ignorance here. I'm not sure where to find documentation
concerning the "transition" between getting all the framework
initialized and the "normal" rails stuff where you're just responding
to http requests one-by-one.

OK, well it does appear to work. I created a file in
config/initializers and put my code in there. It seems to be running as
hoped for. At least in development mode. Thank you Hassan.

As you've noted, config/initializers is the right place for this. For reference or general curiosity, there's a detailed guide to the Rails initialization process here:
