How to call method before index and new from model

I have a method in my model,

def self.interests(user)
    City.joins("INNER JOIN property_of_interests ON property_of_interests.city_id = cities.id").where(:property_of_interests => {:user_id => user})
end

I want to call this method into my controller before index and new action, how can I can I do that ?

And all the model and controller are of different entities

If I use before_filter in the controller how will I pass current_user argument to the method ?

You can pass a lambda, in this case {@interests = Widget.interests current_user}, into before_action to achieve what you want.

app/controllers/widgets_controller.rb

class WidgetsController < ApplicationController
  before_action(only: [:show]) {@interests = Widget.interests current_user}

  def show
    # do something with @interests
  end
end

app/models/widget.rb

class Widget < ActiveRecord::Base
  def self.interests(user)
    City.joins("INNER JOIN property_of_interests ON property_of_interests.city_id = cities.id").where(:property_of_interests => {:user_id => user})
  end
end
