Question

1. AppScreenshot

   class AppScreenshot < ActiveRecord::Base
     include Cacheable
     belongs_to :app
   
     model_cache do
       with_key
     end
   
     scope :available , where(["state > ? and is_icon = ? ",0,0])
   
   end
   

2. App:

   class App < ActiveRecord::Base
     include Cacheable
     #acts_as_cached :ttl => 30.minutes
   
     has_many :apk_files
   
     has_many :app_screenshots.available
   
   end
   

why has_many :app_screenshots.available ?

Answer 1

:app_screenshots is just a Ruby symbol, so you can’t call methods on it like that.

I think something like has_many :app_screenshots, :conditions => 'state > 0 and is_icon = 0'

should work in your case.
