Initialize a variable at start

Rails
#1

I have a class variable (@neo) that that get initialized by using
something:

Graph.connect

where the connect method will initialize the variable @neo

Right now I call the Graph.connect method in any other class that
needs to have the variable initialized.

is there a way to have the variable initialized at the start of the
execution of the app, regardless of point of entry?

You could specify it in a before_filter in application_controller.
Then it will get run for any action.

That would work, but is there a way to have it initialized for both
controllers and models at the start.
Something like the db yaml configs?

What do you mean by initialised for a model?
You said that you are initialising a class variable, I assumed you
meant a controller class variable.

A model is a class as well, right? Maybe, I should explain that the
variable is actually a connection to an external rest-dd, the Graph
model is actually responsible for all interactions with the db.

Right now, I check if the connection is set and if not I set the
connection. What I would like is to have the connection set at app
start.

The answer would be to place this inside the related environments file

config.after_initialize do

   Graph.neo = Neography::Rest.new()
 end
