ruby on rails - How to set in a middleware a variable accessible in all my application? -

-
i using ruby on rails 3 , trying use middlewares in order set variable @variable_name accessible later in controllers. for example middleware is class auth def initialize(app) @app = app end def call(env) @account ||= account.find(1) @app.call(env) end end the above code set @account variable, isn't available in application (in controllers, models, views, ...). so, how can accomplish that? i seen this answer way need, have @account variable "directly accessible". is, without use way making available, example in views, this: <%= debug @account %> you can use 'env' that. in middleware this: def call(env) env['account'] = account.find(1) @app.call(env) end you can value using 'request' in app: request.env['account'] and please don't use global variables or class attributes people suggest here. that's sure way troubles , bad habit.
