variables - Where should I store calculated values I use throughout my application in Rails? -

i have following variable definition:

@monday = (time.now).at_beginning_of_week 

i use in different models, controllers, , views.

where can define (and how should define -- @@? ) can define once , use throughout rails application?

should in environment.rb? should @@?

i add application controller:

before_filter :load_date  def load_date   @monday =  (time.now).at_beginning_of_week end 

so accessible in of yours controllers , views. if want use in models, need param, on example scopes. controller place should pass variable model:

@models = mymodel.before_date(@monday) 

i don't think need have 1 instance of variable whole application. initializing quite simple. not when initialize , don't use it. me hard imagine need in of controllers , actions.

the other way can define class:

class mydate   def self.get_monday     time.now.at_beginning_of_week   end end 

and put in config/initializers (probably there better place put it). can access anywhere in application:

mydate::get_monday
