Question

i i have different class and controller.
and i need that one instance of model will be available in controller/
now i’m doing something like this:

def method1
    inst = @MyClass.new(params)
    inst.action
    ....
def method2
    inst = @MyClass.new(params)
    inst.action

    ....
def method2
     @inst.action

or self.inst i’t doesn’t matter

how i can do it?

def self.inst
    MyClass.new(params)
end

Answer 1

You can use a before_filter callback.

Heres how you use it

 class YourController < ApplicationController

   before_filter :find_resource 

   def action1
      @some_instance.magic
   end

   def action2
     @some_instance.magic
   end

  private
   def find_resource
      @some_instance = YourModel.find
   end

 end

You can also specify the actions that callback is run on with :only or :except options
