Question

Trying to get a value from a object isn’t working out.

  class Asset < ActiveRecord::Base
  attr_accessible :description,
                  :file,
                  :file_cache
  belongs_to :attachable,
             :polymorphic => true
  mount_uploader :file, AssetUploader

In console

  profile = Profile.first

  Profile Load (0.5ms)  SELECT `profiles`.* FROM `profiles` LIMIT 1 etc

profile.assets.inspect

Asset Load (0.6ms)  SELECT `assets`.* FROM `assets` WHERE `assets`.`attachable_id` = 1 AND `assets`.`attachable_type` = 'Profile'
 => "[#<Asset id: 1, description: nil, file: \"fa731ee80a.jpg\", attachable_id: 1, attachable_type: \"Profile\", created_at: \"2012-01-30 00:29:21\", updated_at: \"2012-02-07 22:13:17\">]" 

How would I get the file attribute from this?
Tried numerous things but I just seem to be unable to figure it out

profile = Profile.first then profile.assets.first.file works 

BUT

profile = Profile.where(:user_id => 2 ) then profile.assets.first.file returns a NoMethodError: undefined method `assets' for #<#

Answer 1

Quick answer: profile.assets.first.file

Actual answer: Your profile model should have a has_one :asset, :as => :attachable if each profile will only have one attached file, but it seems that you have a has_many.

Update

Try:

profile = User.find(2).profile
profile.assets

Or:

profile = Profile.where(:user_id => 2).first
profile.assets
